Charger type c. USB: types of connectors and cables for a smartphone. What is USB Type-C?

The first version of the Universal Serial Bus (USB) was introduced in 1995. It is USB that has become the most successful interface in the history of computing systems. Tens of billions of devices communicate with each other via USB, so the importance of this data transmission channel can hardly be overestimated. It looks like with the advent of the connector USB Type-C , our understanding of the capabilities and role of the universal tire may change dramatically. Before talking about the prospects, let's see what the new format universal connector offers.

The advantages and disadvantages of the new format interface connector have been discussed on the net for some time. The USB Type-C specification was finally approved at the end of last summer, but the topic of the universal connector has attracted active interest after the recent announcement of a laptop, as well as a new version equipped with USB Type-C.

Design. Convenient connection

The USB Type-C connector is slightly larger than the usual USB 2.0 Micro-B, but noticeably more compact than the dual USB 3.0 Micro-B, not to mention the classic USB Type-A.


The dimensions of the connector (8.34x2.56 mm) make it easy to use for devices of any class, including smartphones / tablets with a minimum reasonable body thickness.

Structurally, the connector has an oval shape. Signal and power outputs are located on a plastic stand in the central part. The USB Type-C pin header includes 24 pins. This is much more than the previous generation USB connectors. Only 4 pins were allocated for the needs of USB 1.0 / 2.0, and USB 3.0 connectors have 9 pins.

The first obvious benefit of USB Type-C is the symmetrical connector, so you don't have to worry about which side to connect the plug to the outlet. The age-old problem of devices with USB connectors of any format is now finally solved. At the same time, the solution to the problem is achieved by not trivial duplication of all contact groups. It uses some kind of autonegotiation and switching logic.

Another nice thing - identical connectors are located on both sides of the interface cable. Therefore, using USB Type-C, you do not need to choose which side of the conductor to connect the master and slave devices.

The outer shell of the connector does not have any holes or cutouts. Internal side latches are used to secure it in the connector. The plug must be reasonably secure in the connector. There should not be any backlashes similar to those seen in USB 3.0 Micro-B.

Many are probably worried about the physical reliability of the new connector. According to the declared characteristics, the mechanical life of the USB Type-C connector is about 10,000 connections. The same indicator is typical for the USB 2.0 Micro-B port.

Separately, we note that USB Type-C is not a data transfer interface. This is a type of connector that allows you to link together various signal and power lines. As you can see, the connector is elegant from an engineering point of view, and most importantly, it should be easy to use.

Data transfer rate. 10 Gb / s is not for everyone?

One of the advantages of USB Type-C is the ability to use the USB 3.1 interface for data transfer, which promises an increase in bandwidth up to 10 Gb / s. However, USB Type-C and USB 3.1 are not equivalent terms and are definitely not synonyms. In the USB Type-C format, the capabilities of both USB 3.1 and USB 3.0 and even USB 2.0 can be realized. An integrated controller determines the support of a particular specification. Of course, USB Type-C ports are more likely to appear on devices that support high data transfer rates, but this is not a dogma.

Recall that even with the implementation of USB 3.1 capabilities, differences in maximum speed data transmission. For USB 3.1 Gen 1 this is 5 Gb / s, USB 3.1 Gen 2 is 10 Gb / s. By the way, the presented Apple Macbook and Chromebook Pixel have USB Type-C ports with a bandwidth of 5 Gb / s. Well, but a good example of the fact that new interface The other connector is very variable, it is the Nokia N1 tablet. It also comes with a USB Type-C connector, but its capabilities are limited to USB 2.0 with 480 Mb / s bandwidth.

The USB 3.1 Gen 1 designation can be called a marketing gimmick. Nominally, this port has the same capabilities as USB 3.0. Moreover, for this version of "USB 3.1" the same controllers can be used as for the implementation of the bus of the previous generation. At the initial stage, this technique will most likely be actively used by manufacturers, releasing new devices with USB Type-C for which maximum bandwidth is not required. When proposing a device with a new type of connector, many will want to present it in a favorable light, announcing the presence of not only a new connector, but also support for USB 3.1, even if only conditional.

It is important to understand that nominally, the USB Type-C port can be used for maximum performance connection at speeds up to 10 Gb / s, but in order to get such bandwidth, connected devices must provide it. The presence of USB Type-C is not an indication of the actual speed capabilities of the port. They should be preliminarily specified in the specifications of specific products.

Some restrictions also have cables for connecting devices. When using the USB 3.1 interface, for lossless data transfer at speeds up to 10 Gb / s (Gen 2), the cable length with USB Type-C connectors should not exceed 1 meter, for connection at speeds up to 5 Gb / s (Gen 1) - 2 meters.

Energy transfer. 100 W unit

Another important feature that USB Type-C brings is the ability to transfer power up to 100W. This is enough not only for powering / charging mobile devices, but also for the trouble-free operation of laptops, monitors or, for example, "large" external storage format 3.5 ”.

In the original development of the USB bus, power transmission was a secondary function. The USB 1.0 port provided just 0.75W (0.15A, 5V). Enough for mouse / keyboard operation, but nothing more. For USB 2.0, the nominal current was increased to 0.5 A, which made it possible to get already 2.5 W. This was often enough to power, for example, external hard drives format 2.5 ". For USB 3.0, a current of 0.9 A is nominally provided, which, with a constant supply voltage of 5V, already guarantees a power of 4.5 W. Special reinforced connectors on motherboards ah or laptops were capable of delivering up to 1.5 A to speed up charging of connected mobile devices, but this is still 7.5 W. Against the background of these numbers, the ability to transmit 100 watts looks like something fantastic. However, in order for the USB Type-C port to fill the necessary capacity, support for the USB Power Delivery 2.0 (USB PD) specification is required. If there is none, the USB Type-C port will be able to supply 7.5 W (1.5 A, 5 V) or 15 W (3A, 5 V) to the mountain, depending on the configuration.

In order to streamline the power capabilities of the USB PD ports, a system of power profiles has been developed that allow for possible combinations of voltages and currents. Compliance with Profile 1 guarantees the ability to transfer 10 W of energy, Profile 2 - 18 W, Profile 3 - 36 W, Profile 4 - 60 W, Profile 5 - 100 W. The port corresponding to the higher profile maintains all the states of the previous downstream. 5V, 12V and 20V are selected as reference voltages. The use of 5V is essential for compatibility with the vast array of USB peripherals available. 12V is the standard supply voltage for various system components. 20V is proposed taking into account the fact that external power supply units for 19-20V are used to charge the batteries of most laptops.

Of course, it's good when the device is equipped with USB Type-C supporting the maximum USB PD energy profile. It is this connector that allows you to transfer up to 100 watts of energy. It is obvious that ports with similar potential may appear on some powerful laptops, special docking stations or motherboards, where separate phases of the internal power supply will be allocated for the needs of USB Type-C. The point is that the required power must be generated somehow and brought to the USB Type-C contacts. And to transfer energy of such power, active cables will be required.

It is important to understand here that not every port of the new format will be able to provide the declared power of 100 watts. There is a potential for this, but this issue must necessarily be resolved by the manufacturer at the circuitry level. Also, do not entertain the illusion that the above 100 W can be obtained, say, from a power supply the size of a matchbox, and now you can power your gaming laptop and a 27-inch monitor connected to it with a smartphone charge. Nevertheless, the law of conservation of energy continues to work, and therefore an external 100 W PSU with a USB Type-C port will still be the same weighty block as before. In general, the very possibility of transmitting energy of such power using a universal compact connector is, of course, a plus. At the very least, this is a great opportunity to get rid of the inconsistencies in the original power connectors, which are especially common among laptop manufacturers.

Another useful feature of USB Type-C is the ability to change the direction of power transmission. If the circuitry of the devices allows, the consumer can, for example, temporarily become a source of charge. Moreover, for the reverse energy exchange, you do not even need to reconnect the connectors.

Alternative mode. Not USB single

The USB Type-C port was originally designed as a universal solution. In addition to direct USB data transfer, it can also be used in Alternate Mode to implement third-party interfaces. This flexibility of USB Type-C has been exploited by the VESA by introducing the ability to stream video through DisplayPort Alt Mode.

USB Type-C has four Super Speed ​​USB lines (pairs). If two of them are dedicated to the needs of DisplayPort, this is enough to get a picture with a resolution of 4K (3840x2160). At the same time, the speed of data transfer via USB does not suffer. At its peak, this is still the same 10 Gb / s (for USB 3.1 Gen2). Also, the transmission of the video stream does not in any way affect the energy capacity of the port. Even high-speed 4 lines can be allocated for DisplayPort needs. In this case, modes up to 5K (5120 × 2880) will be available. In this mode, USB 2.0 lines are not involved, so USB Type-C will still be able to transfer data in parallel, albeit at a limited speed.

In the alternative mode, the SBU1 / SBU2 pins are used to transmit the audio stream, which are converted to the AUX + / AUX- channels. They are not used for the USB protocol, so there are also no additional functional losses here.

When using the DisplayPort interface, the USB Type-C connector can still be connected either way. The required signal matching is provided initially.

Connecting devices using HDMI, DVI and even D-Sub (VGA) is also possible, but this will require separate adapters, however, these must be active adapters, since for DisplayPort Alt Mode, Dual-Mode Display Port (DP ++) is not supported ...

Alternative USB mode Type-C can be used for more than just DisplayPort. Perhaps we will soon learn that this port learned, for example, to transfer data using PCI Express or Ethernet.

Compatibility. Difficulties of the "transition" period

If we talk about the compatibility of USB Type-C with devices equipped with USB ports of the previous generation, then it is not possible to connect them directly due to the fundamental differences in the connector design. To do this, you need to use adapters. Their assortment promises to be very wide. Of course, it's not just about converting USB Type-C to other USB types. Display adapters for displays with traditional DisplayPort, HDMI, DVI and VGA ports will also be available.

Apple simultaneously with the announcement new MacBook offered several options for adapters. A single USB Type-C to USB Type-A is priced at $ 19.

Given the presence of only one USB Type-C, the owner of a MacBook probably cannot do without a universal, more functional converter. Apple has introduced two of these adapters. One at the output has a pass-through port USB Type-C, VGA and USB Type-A, the second option is equipped with HDMI instead of VGA. The cost of these boxes is $ 79. A 29W PSU with native USB Type-C costs $ 49.


Google for new system The Chromebook Pixel offers single USB Type-C to Type-A (male / female) adapters for $ 13, while a DisplayPort / HDMI converter costs $ 40. The 60W PSU is priced at $ 60.

Traditionally, one should not expect humane price tags for additional accessories from equipment manufacturers. Adapter manufacturers are anticipating the demand for their new products. Belkin is already ready to ship kilometers of conductors, but their cost cannot be called low either ($ 20-30). The company also announced, but has yet to provide a USB Type-C to Gigabit Ethernet adapter. The cost has not yet been announced, there is only information that it will be available in early summer. It's funny, but it seems that up to this point, to connect to a wired network, you will need to use two adapters at once. It is possible that someone will be quicker than Belkin by offering an appropriate adapter earlier.

It will be possible to talk about a noticeable price reduction only after much less well-known companies from the "Celestial Empire" are tightly engaged in accessories with USB Type-C. Considering what prospects are opening up, we believe that they will not be the case.

USB Type-C devices. Someone must be first

Nominally, the tablet was the first device equipped with a USB Type-C port. At least, it was this device that became a harbinger of the fact that the ports of the new format left the development laboratories and "go to the people."

An interesting device, but, unfortunately, so far it is offered in a fairly limited edition. The tablet has a native USB Type-C port, although the USB 2.0 protocol is used for data transfer.

Perhaps the most iconic product to help boost the popularity of USB Type-C is its recent release. The 12-inch laptop is equipped with a single interface connector, so its owners will somehow become pioneers who will adapt to life with USB Type-C.

On the one hand, Apple obviously supported the development of the new standard, moreover, the company's engineers were directly involved in the development of USB Type-C. On the other hand, updated versions Macbook air and MacBook Pro did not receive this connector. Does this mean that in the "heavier" category of devices of the manufacturer USB Type-C will not be registered in the coming year? Controversial. After all, surely Apple will not be able to resist updating the line of laptops after the autumn announcement of Intel's new mobile platform with Skylake processors. Perhaps it is then that the Cupertines will allocate space on the interface panel for USB Type-C.

The situation with tablets and smartphones is even more controversial. Will Apple use USB Type-C for them instead of Lightning? In terms of capabilities, the proprietary connector is noticeably inferior to the new universal port, but what about the original peripherals that users of Apple mobile products have accumulated since 2012? We will find out the answers to these questions with the update or expansion of the iPhone / iPad lines.

Google has unveiled the second generation of stylish Chromebook Pixel laptops. Chrome OS systems are still quite niche solutions, but the quality Google systems captivating, besides, this time they are at the forefront of devices offering to join USB Type-C. Laptops are equipped with a pair of matching connectors. However, as a safety net, the Chromebook Pixel also has two classic USB 3.0 ports.

In general, Google representatives are very encouraged by the capabilities of the new connector, counting on the emergence of Android mobile devices with a USB Type-C connector in the near future. Uncompromising support for the largest platform holder is a powerful argument for other market players.

Motherboard manufacturers have been slow to add a USB Type-C port to their devices yet. MSI recently introduced the MSI Z97A GAMING 6, which is equipped with this connector with a data transfer rate of up to 10 Gb / s.

ASUS offers an external USB 3.1 controller with a USB Type-C port, which can be installed on any board with an empty PCI Express (x4) slot.

Peripheral devices with native USB Type-C are still frankly not enough. Surely, many manufacturers were in no hurry with the announcement, waiting for the emergence of systems with which it would be possible to use products with USB Type-C. In general, this is a typical situation when implementing the next industry standard.

Immediately after the announcement Apple MacBook LaCie has introduced a series of USB Type-C external portable hard drives.


SanDisk is already offering a USB 3.0 Type-A and USB Type-C flash drive for trial. A similar product is offered by the lesser-known Microdia.

We will surely see a significant expansion of the range of USB Type-C devices soon. The flywheel of change will slowly but surely unfold. The support of "big" companies can influence the situation and speed up this process.

Outcomes

The need for a universal compact connector that could be used to transfer data, video-audio streams and electricity has been long overdue. Considering the mutual interest of both users and equipment manufacturers, there are all the prerequisites for USB Type-C to "shoot".

Compact size, simplicity and ease of connection, along with ample opportunities promise the connector to repeat the success of its predecessor. The familiar USB port has been upgraded several times, but the time has come for fundamental changes. 10 Gb / s with the possibility of further scalability, power transmission up to 100 W and a picture with a resolution of up to 5K. Not a bad start? Another argument in the USB Type-C piggy bank is an open standard that does not require royalties from manufacturers. There is still much work to be done, but the result is visible ahead, for the sake of which it is worth walking this path.

The rapid development of computer technology affects not only the basic components of systems. The possibilities are increasing, including various interfaces. As for the most common connection method peripheral devices, - USB, - here, in general, we can state a multiple increase in productivity in recent years. Universal Serial Bus bandwidth increases and functionality expands. The connectors used to connect a variety of USB devices are also subject to changes. Today, many people hear about USB, what are the advantages and disadvantages of the solution - the topic of this article.

Modern computer connectors

Glancing around the case of almost any laptop, you can find a number of different ports located on the sides. Among them there is definitely USB, almost always HDMI and some others. Modern models are often equipped with the latest USB Type-C port. What this connector is, many do not know, but it would be worthwhile to familiarize yourself with the capabilities of the port. Presumably, the connector will replace many other solutions in the future and become a truly universal standard. This is facilitated by the technical characteristics of the new way of pairing the computer and peripherals. The USB Type-C port offers users faster data transfer speeds, improved functionality, and new level ease of use. In short, the future of the standard looks very promising.

Many applications of one cable

The creators of USB Type-C used very simple idea... The user must have a single type of cable, and his computer equipment is equipped with one type of port. Anything can be connected by using a unified interface. For example using USB cable Type-C, can be plugged in at its core different devices represented by hard drives, monitors, audio interfaces, smartphones, tablet PCs. Among other things, it becomes possible to use the connector in question even for charging a laptop.

USB-A

Today, almost all peripheral devices are connected to a PC via the familiar USB-A connector. This port has firmly entered the computer world, has a familiar rectangular shape, and its use has become almost the standard for interfacing with PCs and laptops flash drives, external keyboards, mice, hard drives, printers and many other devices. This monopoly is likely to be broken soon - the USB Type-C cable is already taking its rightful place among the solutions used to connect a variety of devices.

Change of concept

Various cables are used to connect devices to the long-established USB-A port. The main difference between them is the connector located on the opposite side of the cable that connects to the computer. This is almost always a different type of connector. For example, micro-USB is used for smartphones, mini-USB is often used for other gadgets. You need a USB-B cable to connect your printer, and a micro USB-B cable to connect storage devices. This variety causes some inconvenience and complexity, because a user who owns several devices always needs to have a whole set of cables at hand. Designed to be the same for all devices, that is, the universal USB Type-C cable simplifies this situation many times over.

New format

With the development of the standard, it became possible to establish a single connector design for all devices, as well as the same connector at both ends of the cable. How to understand, picking up a USB Type-C cable, what exactly is it? The solution is a slim, oval-shaped connector that is significantly smaller than previous cable and connector formats of this type. In addition, USB 3 Type-C received essential characteristic represented by symmetry and reversibility. Overall very similar to the Lightning solution from Apple- very convenient, because you do not need to waste time manipulating the cable to find the right way to connect.

Future

Probably, today it can be argued that after a certain time, the USB Type-C connector will turn into the only universal port for all peripheral devices. Thus, there will be a replacement for USB-A, B, micro-USB and mini, which complicate the life of ordinary users today. All cables should be the same and be usable for any device. Of course, quick unification will not happen, too many workable devices with connectors other than USB Type-C are used today and will be in operation for several more years.

However, do not forget: the expansion of new solutions has already begun. For example, a USB Type-C flash drive is no longer a rarity on the shelves of computer stores. In addition, the fact of the release of flagship devices from the most famous brands equipped with the port under consideration, suggests that the described situation, i.e., the ousting of obsolete connectors from the market, will sooner or later come. For compatibility with old solutions, you will have to use a USB Type-C adapter for now.

Compatibility

After reading the above, you can think about what to do with already purchased devices equipped with connector types other than USB Type-C. I must say that this issue should not cause much concern. A wide variety of adapters have already been developed, produced and sold, allowing you to connect any device with a USB connector, regardless of its type. Adapters such as mini-USB - Type-C, micro-USB - Type-C and others are already widespread and perform their functions perfectly. The principle of support, which has been applied in computer technology for many years, is not going to be violated. If there is a USB Type-C port in a new laptop or computer, an adapter for other types of connector is a completely applicable and effective solution.

Learn more about the benefits of the connector

Of course, a simple design revision to which the connector and port have undergone will not be a weighty reason for encouraging the user to upgrade all the peripherals he has, but performance is far from the only advantage of the new solution. The new format supports the most modern USB 3.1 protocol, which carries an increase in the speed of data exchange and greater versatility in comparison with previous versions that are used on devices equipped with USB-A.

Speed

More than two decades have passed since the presentation of the first version of the connector. At that time, the maximum data transfer rate was 12 Mb / s. Today it can be argued, considering USBType-C, that this is the most fast interface for connecting peripheral devices from existing solutions. The USB 3.1 standard is capable of providing a data transfer rate of 10 Gb / s.

Performance

The additional advantages of the standard under consideration, of course, should include the performance represented by the ability to provide power transmission up to 100 watts. This figure is enough to power almost any laptop, not to mention smartphones, tablets and other gadgets. In addition to energy, the new format supports the transmission of a huge amount of data per unit of time. For example, already today, a video signal in 4K resolution is successfully transmitted via USB Type-C.

Versatility

The versatile nature of the latest standard opens up a wide range of practical applications. Mass useful functions can be provided with a single cable. For example, you can connect equipped USB-C laptop to an externally powered monitor and charge the laptop battery while watching video content. When storage devices are connected to the display, such as external drive, from a laptop you can access the information stored on the media.

Disadvantages of USB Type-C

This connector is a brilliant new format, no doubt claiming to be a ubiquitous solution in the very near future. At the same time, the initial stages of distribution and development, at which in this moment is still a standard, does not provide a complete absence of hazards, and also some confusion when using the connector.

Cheap accessories

The main problem that a user who decides to join modern trends may face is cheap, low-quality accessories and cables. In view of a large number the energy transmitted through the USB Type-C connectors, the use of cables of insufficient quality may damage the paired devices. This factor must be taken into account by users without fail. When buying cables and adapters, you should choose products from reliable trusted brands.

Confusion in standards

Another unpleasant moment that users of USB Type-C may face today is caused by the fact that the standard in question refers more to the type of connector used, rather than to the specifications of the interface itself. Therefore, it is quite possible that a device connected to a new connector will not work as fast as the owner of the device expected. The first generation uses USB 3.0 technology, providing a maximum speed of 5 Gb / s. The second generation USB-C supports the 3.1 standard, through which the data transfer speed reaches 10 Gb / s. Problems with each of the ports arise due to the fact that they look the same, but in the production of ready-made solutions, brands use different components even in the lines of similar models. In other words, before buying a device with a USB Type-C connector, you need to check that the actual specifications of the port correspond to the required parameters.

Lately, it is even easier to surprise people than it seems. When we were shown USB connector Type-C all just gasped, because it's so cool, now you can even put your device on charge the first time even at night. But is it worth it? Maybe USB Type-C isn't as good as it sounds? Maybe he is not needed at all now? Yes maybe…

Lately, it is even easier to surprise people than it seems. When we were shown the USB Type-C connector, everyone just gasped, because it's so cool, now you can even put your device on charge the first time even at night. But is it worth it? Maybe USB Type-C isn't as good as it sounds? Maybe he is not needed at all now?

Yes, the ability to charge your smartphone when you are drunk can be a good thing. Or maybe this is just another marketing ploy of large companies, so that you once again buy yourself a new tablet or smartphone? In this article, we have described five reasons why you don't need USB Type-C now.

1. USB Type-C does not mean "fast charging"

One of the most common myths about this connector is that it will charge your devices faster. This is not true. This is just a new version of the connector. Type-C is the same as previous standards, fast charging has nothing to do with it. Despite the fact that it supports the USB 3.1 standard, which carries a number of improvements, you should not think that it will be so on all smartphones.

OnePlus 2 is the most striking example of this. It has a USB Type-C connector, but the USB 2.0 standard, which does not give it any advantages, except for a "universal" cable, over older smartphones. In addition, there is still not a single smartphone that supports a new type of connector and a fast battery charging mode.

2. There will be no huge data transfer speed either

The second myth is the assumption that with it you will be able to transfer data at the speed of light compared to older solutions. Here, too, everything rests on such industry standards as USB 2.0, 3.0, 3.1. It is on these standards that the data transfer rate depends, but not in any way on the shape of the cable.

3. You will have to store it as "the apple of your eye"

If you are going somewhere to go on vacation and have forgotten the MicroUSB cable at home, then there is nothing to worry about, because you can charge your smartphone with a charger from the tablet, or you can even use someone else's cable for charging, because this standard distributed all over the world.

But the owners of the same OnePlus 2 will have to endure for an unknown amount of time and carry the cable all the time in their pocket or backpack. After all, if the battery of your smartphone "dies", then there will be simply nowhere to charge it. That is why, devices with such connectors need to be bought at least in a year, when there will already be a sufficient number of smartphones / tablets with this type of charger on the market. So do not chase the desire to get into the connector even at night, because by this you will have another significant problem that I described above.

4. The cable is rare and expensive

If you suddenly lose your cable, then you will have a hard time. First, in short time it is almost impossible to find it. Secondly, if you find it, then its cost is much higher than you think. And all because now the demand for this product is minimal.

5. Old accessories will become useless

Surely, you, like me, have a huge box of various trinkets and accessories for your smartphone. After purchasing a main device with a USB Type-C connector, they will all become useless in an instant. Since the "old" Type-A connectors are physically incompatible with the new type of cable. Of course, special adapters will help you, but think, is it worth it?

The new USB Type-C standard is still underdeveloped in the market, but manufacturers are gradually adopting the new technology. In smartphone manufacturing, USB-C is already a new trend, because it is not only an improved charging connector, but also a means of abandoning the traditional 3.5mm headphone port. Today we will talk in more detail about USB Type-C, and this article will tell you what it is.

Almost all electronic devices today are equipped with a USB connector. From desktops to smartphones to a variety of laptop drives. USB is the ubiquitous standard when it comes to connecting peripherals or transferring data between devices. The last major USB update came in 2013 with the release of USB 3.1, accompanied by the release of a new Type-C connector. As you can see, almost 4 years have passed since then, and Type-C has not taken root.

Currently on the market you can count on one hand the number of devices using USB Type-C technology. Among computers, these are the latest laptops from Apple, from Google, the line from Samsung and several other hybrid devices. Among smartphones, there are mainly flagships of the outgoing year:, and.

So why USB Type-C is better than their predecessors? Let's find out.

What is USB Type-C

USB Type-C is a new and rapidly evolving industry standard for data transmission for computers and mobile devices. The main and most significant innovation of Type-C is the redesigned connector - universal, balanced, capable of working on either side. The USB-C connector was invented by the USB Implementers Forum, a group of companies that developed and certified new standard USB. It also includes the largest technology companies such as Apple, Samsung, Dell, HP, Intel and Microsoft. By the way, this is important to know, because therefore USB Type-C has been easily adopted by most PC manufacturers.

USB-C is the new standard

The first thing to know is that USB Type-C is the new industry standard. Just like they used to be USB 1.1, USB 2.0, USB 3.0, or the most recent USB 3.1. Only previous generations of USB were more focused on increasing data transfer speed and various other improvements, while Type-C from a physical point of view changes the design of the connector in a similar way to the modifications of the technology - MicroUSB and MiniUSB. However, the decisive difference in this case is that, unlike MicroUSB and MiniUSB, Type-C is aimed at replacing absolutely all standards, and on both sides (for example, USB-MicroUSB).

Main characteristics:

  • 24 signal outputs
  • USB 3.1 support
  • Alternative mode for implementing third-party interfaces
  • Speed ​​up to 10 Gbps
  • Energy transfer up to 100 W
  • Dimensions: 8.34x2.56 mm

USB Type-C and USB 3.1

One of the possible questions for those who do not know about USB Type-C could be something like this: what does USB 3.1 have to do with USB Type-C? The fact is that USB 3.1 is the main data transfer protocol for Type-C. The speed of version 3.1 is 10 Gbps - in theory, this is 2 times faster than USB 3.0. Another USB 3.1 can be presented in the original connector format - this port is called USB 3.1 Type-A. But today it is much easier to find USB 3.1 with the new Type-C universal connector.

USB versions

To better understand why Type-C will replace traditional USB versions, the first step is to understand the difference between the two. There are different versions of USB, as well as even different connectors - for example, Type-A and Type-B.

The USB versions refer to a common standard, but the difference lies in the maximum data transfer rate and operating power. Of course, there are many other factors as well.

USB 1.1
Although USB 1.0 is technically the first version of USB, it has failed to fully reach the market. A new one was released instead. USB version 1.1 - it just became the first standard to which we are all accustomed. USB 1.1 can transfer data at a speed of 12 Mbps and draws a maximum of 100 mA of current.

USB 2.0
The second version of USB was introduced in April 2000. It provided the standard with a significant increase in the maximum data transfer rate - up to 480 Mbps. Also, USB 2.0 has become more powerful, consuming 1.8A at 2.5V.

USB 3.0
The USB 3.0 release brought with it not only the expected improvements in data transfer speed and power, but also new types of connectors. Moreover, USB 3.0 even got its own color - new version The standard has been marked in blue to valiantly distinguish it from older generations of USB. USB 3.0 can operate at speeds up to 5 Gbps, taking 5V to 1.8A for its operation. By the way, this version was presented in November 2008.

USB 3.1
Newest and most best version USB was released in July 2013, although it is still not widely used. USB 3.1 can provide users with a bandwidth of up to 10 Gbps with a maximum power consumption of 5V / 1A, or optionally 5A / 12V (60W) or 20V (100W).

Type-A
Type-A is the classic USB interface. The short and rectangular plug became the original design for USB and remains the standard connector for use at the host end of a USB cable to this day. There are also some variations of Type-A - Mini Type-A and Micro Type-A, but these have never been widely accepted by the public due to the intricate socket. Both of these Type-A variations are now deprecated.

Type-B
If Type-A has become one side of the USB cable we are used to, then Type-B is the other. The original Type-B is a tall connector with beveled top corners. Commonly found in printers, although it is itself an extension of the USB 3.0 standard to introduce new connectivity options. Classic MiniUSB and MicroUSB are also available in the Type-B version, along with the absolutely awkward MicroUSB 3.0, which uses additional plugs.

Type-C
Thus, after Type-A and Type-B, we have approached, obviously, the newest Type-C. The Type-A and Type-B versions were supposed to work together with each other through backward compatibility, but the arrival of Type-C completely ruined these plans, as USB-C implies a complete replacement of legacy USB connection technologies. Also, the Type-C was specially designed so that additional variants of the Mini or Micro type would not need to be produced at all. This, again, is due to the intention to replace all current connectors with USB Type-C.

The main feature of the Type-C standard is the versatility or symmetry of the connector. USB-C can be used on both sides just like Apple's Lightning technology - no more special connection sides that are hard to find in the dark. Also the Type-C version is based on USB 3.1, which means it supports all the benefits latest version, including the highest speed.

USB-C is still backward compatible with existing USB variants, but adapters will of course be needed for this use case.

Disadvantages of USB Type-C

Of course, the new USB Type-C standard also has problems. One of the main and most serious concerns of the latest version of the technology is called the physical design of the connector - it is very fragile due to the symmetrical design. Apple, despite the same versatility with its Lightning, uses a sturdy metal plug that is much more robust.

Even more relevant and of great concern USB problem Type-C is an unregulated connector that has resulted in a number of dangerous commercially available accessories. Some of these accessories, through the use of unsupported voltage levels, can "fry" the connected device. For example, this was the case with the flagship that was magnificent at the start, which subsequently began to ignite at first, and then completely explode in the hands, trousers, cars and apartments of its owners.

This problem led to the obvious and only solution - a massive ban on the production and sale of non-original accessories with USB Type-C support. Thus, if an accessory does not meet the standard specifications of the USB Implementers Forum Inc., the product will not be eligible for sale. Also, to verify the operational status and authenticity of various third-party accessories, USB-IF has provided 128-bit encrypted software that will allow devices with this connector to perform automatic check connected USB-C device or accessory.

Minuses:

  • Design. The USB Type-C design is good, but the design has suffered - it's rather fragile. Apple uses an all-metal plug in its Lightning, while the Type-C uses an oval shape with the signal pins in the center.
  • Connector operation. If USB Type-C is allowed to operate at unsupported voltage levels, the cable and / or device is likely to catch fire.
  • Compatibility. USB Type-C is an innovation in the USB world, but latest generation leaves old devices in the past because it does not support working with them.
  • Adapters. To fully work with USB Type-C on older devices, you will have to buy adapters. This is an additional waste of money.

Benefits of USB Type-C

Despite all of the above, USB Type-C can be confidently called a step forward for the industry. Installing this connector will allow manufacturers to make thinner computers and mobile devices with fewer ports, superior data transfer rates and headphone jacks. In the future, if USB Type-C hits the masses, the connector will be able to replace not only the 3.5 mm headphone port, but also HDMI - the interface used for video transmission. So USB Type-C will replace the usual connectors today and become a universal standard in any situation.

Pros:

  • Symmetry. USB Type-C allows you to forget about situations when you have to remember from which side to insert the cable into the connector. Also, from now on, you can not be afraid not to find the right side of the USB in the dark.
  • Compactness. The dimensions of USB Type-C are 8.4 x 2.6 mm, which allows manufacturers to make computers and mobile devices much thinner.
  • Versatility. Thanks to the integration of a single connector, it will be possible to charge both a laptop and a tablet or smartphone with one cable.

It would seem that the USB Type-C standard has just begun to earn a reputation for itself in the world. mobile technologies, but 2015 has already given us a certain number of devices that have tried on a new interface: the memories of OnePlus 2, Nexus 5X and Nexus 6P are still fresh.

There is no doubt that the number of such devices will grow relentlessly this year. Largest manufacturers will continue to wage a fierce struggle for the consumer, supplying Type-C connectors not only to their flagship models but also offers in lower price segments.

If you regularly use external batteries or other portable charging device designed for microUSB - will add to your headache: in order to continue to benefit from your favorite accessories, be ready to fork out for a dozen different adapters.

But there is Alternative option- external battery, or the so-called Power bank, with an already built-in connector for the USB Type-C connector, which, among other things, has a number of significant advantages over competitors: recharging the device through the Type-C connection is much faster, and you do not have to carry all the necessary adapters with you.

On the pages of online stores, you can find dozens of different names of portable chargers. It looks like it's time to figure out which items are worth buying. Taking into account the brand, rating and positive reviews, we have compiled a small subjective list for you. And if the power banks presented below are not in your local store, their cost allows you to order them on ebay, amazon or another online platform without any problems with customs.


The 20,100mAh Anker PowerCore + will set you back around $ 51. For this money, you get a device with a LED charge indicator, two USB ports with an output current of 2.4 A, and one USB Type-C port. Actually, the kit itself consists of a "power bank", a USB / USB Type-C cable for recharging the battery, a case and a wire for microUSB.

Note that Anker PowerCore + boasts several unique finds that are responsible for the legitimate power of your. The proprietary PowerIQ technology replicates the charging protocols of each plug-in gadget, making the procedure safe and as efficient as possible. VoltageBoost will also be useful: it determines the resistance of the cable, thereby ensuring process stability. Unfortunately, Anker PowerCore + does not support Qualcomm Quick Charge 2.0 technology.


The external battery CHOETECH with 10400 mAh inside costs $ 32. There are two USB ports on board, one of which is compatible with Qualcomm's Quick Charge 2.0 technology. The USB Type-C connector can be used to connect to a Macbook, Nexus 6P or Pixel C. Includes the Power Bank itself and a USB / USB Type-C cable. There is also a guarantee for 18 months. The device charges both via microUSB and via the USB Type-C interface.

In fact, the CHOETECH doesn't look very impressive when compared to the Anker model. It costs $ 20 cheaper, but half of the capacity is lost somewhere along with the price. Only its modest weight and size, as well as support for Quick Charge 2.0, can tip the scales in favor of CHOETECH.


The price of the RAVPower 20,100 mAh power bank is about $ 60. Discreet design - a black box with a four-point LED-indicator - clearly contrasts with excellent functionality: microUSB connector responsible for recharging RAVPower; one more USB port is ready to cooperate with Qualcomm Quick Charge 2.0 and 3.0 technologies; speed is provided by USB 3A Type-C interface.

The iSmart port is a peculiar feature of the battery. With its help, RAVPower recognizes the type of connected device and optimizes its operation based on the information received.

It is noteworthy that the declared 20,100 mAh should be enough to bring the Galaxy S6 back to life five times; recovery full charge iPhone 6S you will have about 8 tries. Also, RAVPower is able to protect your device from overcharging and keep its sensitive microcircuits healthy.

All in all, RAVPower is a great choice for those who dream of a roomy portable battery with a bunch of additional opportunities and Quick Charge support from Qualcomm. What else can you say, a luxurious thing with an equally “luxurious” price.


Talentcell 10400 mAh power supply is the most cheap accessory on our list. Its cost is $ 27. It is charged via microUSB 2.0, there is a USB Type-C connector. The battery status is displayed by a small LED indicator. In the package you will find a Power Bank and a Type-C cable. You can use Talentcell with any gadget, except for the 12-inch handsome Macbook. This wonderful battery also allows you to charge two smartphones at the same time.

If you do not have extra funds to buy an expensive “power bank”, Talentcell is ready to offer its services. The project's reviews are quite good, but if you are still confused by a little-known brand, think about purchasing the options discussed above.


And again, a product with a not too big name, but an attractive price. Such is the dilemma: for $ 32 you can buy Talentcell and two Big Mac Menus or iVoler with its 10000 mAh, standard USB port and Type-C interface. The lack of support for Qualcomm Quick Charge here is compensated by the possibility of "mega" fast charging from 0 to 100 percent in 3.5 hours.

It seems to us that it is better to take TalentCell and eat, but additional option nevertheless, it was worth considering - after all, fast food is a harmful thing.
