Types of USB connectors. What you need to know about USB Type-C - the only connector in the new MacBook Usb type c description

Have you ever met a person who enthusiastically said, "My smartphone has Type-C"?

The debate about the modernity and the usefulness of the new interface has been going on for a long time. Some consider it the future, others - a utopia. The trouble is that both sides have strong evidence that they are right. To understand the situation, it is necessary to comprehensively study the issue.

Development

Not everyone remembers the first USB Type-A connector, which is still used today in the latest computers, laptops and tablets. In the distant 90s, it had the same physical form, but a different standard - USB 1.1. In more detail, there were restrictions on the data transfer rate.

In 2001, the 2.0 standard was developed, which is the most widespread today. It provided data transfer rates up to 480 Mbps. At this moment, the era of creation of a universal and high-speed connector for connection began.

The first generally accepted connector, which gained great popularity and distribution, was the Type-B Mini. It is successfully used in telephones, cameras, camcorders and allows you to connect devices to a computer. However, this should not be considered a big breakthrough, only the form has changed, the standard has remained the same - USB 2.0. In other words, the transfer rate has not increased.

The desire to minimize the size of gadgets has led to the creation new Type-B Micro. He continues to be the protagonist of the overwhelming amount of modern technology, but he cannot offer users great advantages.

The real breakthrough was the USB 3.0 specification, which radically changed the way we look at many things. The new interface made it possible to increase the data transfer rate up to 5 Gbps. The changes also affected the internal structure. In the new 3.0, a 9-pin group is presented (in 2.0 there were only 4 contacts).

The final step towards the emergence of Type-C was the adoption of the 3.1 standard, which remains the fastest and most efficient today. Users are now able to transfer data at speeds up to 10 Gbps. The new standard also allows a 100W charge to be transmitted.

The standard consists of 24 pins: two rows of 12 each. 8 pins of USB 3.1 interface are used for data exchange at high speed. Pins B8 and A8 (SUB1 and 2) are used to transmit analog signals into headphones (right and left), A5 and B5 (CC1 and 2) are required to select the power mode. There are also ground (GND) and power (V +) pins.

Benefits of Type-C

It is not so necessary, but just another physical modification that has received support for USB 3.1. But don't jump to conclusions, as there are a number of advantages that the new connector offers:

• Security... The connector is reversible, i.e. you can connect the cable in any position. This ensures complete safety and the safety of the gadget from breakdowns, which are accompanied by bent or broken contacts.
• Versatility... Fully compatible with all legacy standards starting with USB 1.1.
• Independence... Type-C supporting USB 3.1 can supply up to 100W of power to connected devices. Simply put, when connecting, there is not only a full-fledged power supply, but also recharging the batteries of other gadgets, as from "".
• Compactness... The connector has very small dimensions, therefore it is actively used in the production of modern tablets and tablets.

disadvantages

From a technical point of view, USB Type-C is almost perfect. So why hasn't it become the most popular yet? Why are manufacturers in no hurry to equip their equipment with them? There are no obstacles for technical equipment, but there are good reasons that slow down this process.

First of all, it has a unique physical structure, therefore, to connect most gadgets, you need adapter cables, all kinds of splitters and adapters. If the connected device does not support USB 3.1, such a connection simply loses its meaning, since the maximum data transfer speed and power support will not be provided.

Most of the released computer, mobile, audio and video equipment are equipped with Type-A, Type-B Mini / Micro, which do not have support for USB 3.1 or even 3.0. The massive move to USB Type-C will reduce demand for existing products that lack it. Regardless of the wishes and expectations of users, manufacturers deliberately push back effective technology and slow down its spread.

Second, even with two Type-C plug-in devices, it may not be possible to get the full benefit. This is due to the imperfect technology of processing and transmitting information of certain categories of devices. For example, you can sync your smartphone and personal computer / laptop via Type-C. However, data transfer in both directions will be limited, since the hard drive will not be able to provide the maximum speed.

Yes, new technology is available, it is in use, but the transition is still far from complete. You need to understand that in the event of a complete transition to USB Type-C, you will have to send all outdated equipment for recycling.

New USB standard Type-C is still underdeveloped in the market, but manufacturers are gradually adopting new technology. In smartphone construction, 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.

Today almost everyone electronic devices are equipped with a USB connector. From desktop computers to smartphones and 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 technology Type-C. 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 is USB Type-C better than its 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 the previous generations of USB were more focused on increasing data transfer speeds and various other improvements, while Type-C from a physical point of view changes the design of the connector in the same way as 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. More 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. Instead, a new version of USB 1.1 was released - it was just this that 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
USB output 3.0 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 throughput 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. Short and rectangular steel plug original design for USB 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, beveled connector upper 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 However, the arrival of Type-C completely thwarted those plans, as USB-C is meant to completely replace legacy USB connectivity technologies. Also Type-C has been specially designed to additional options such as Mini or Micro did 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 options USB, but for such a use case, of course, you need adapters.

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 support Type-C. Thus, if an accessory does not conform to 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. Allowing USB Type-C to operate at unsupported voltage levels is likely to cause the cable and / or device 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. For full-fledged 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 8.4x2.6 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.

Why is the new USB standard really better than the usual USB ports of phones, tablets or laptops, and which devices already have USB Type-C connectors? The CHIP editors answer all these questions.

At first a little important information: The designations USB Type-C and USB 3.1, as they say, go toe-to-toe, since they mean virtually the same thing. When the numeric designation USB 3.1 is used, it is usually referring to the baud rate.

If you come across the name USB Type-C, it usually means directly the type of connector for connecting devices. First, let's compare the previous USB 3.0 standard with new USB 3.1. All details can be found in the table below.

Comparison of USB 3.0 and USB 3.1

Best USB Type-C Devices

What USB Type-C devices are currently available? The first of these was the 12-inch MacBook, in which this connector was generally the only one. The current Nexus 6P and 5X googlephones are also equipped with USB 3.1 - and in general, more and more manufacturers are integrating a port of the new standard into their smartphones.

In the following table, we have compiled a list of the most interesting USB Type-C devices for you.

USB Type-C: these devices already have it

The USB connector can no longer be connected incorrectly

USB Type-C: Type C plug (left) can be used either side

This is what makes USB Type-C so incredibly convenient: It is symmetrical. You no longer have to worry about trying to get the right plug into the socket. Previously, this property of the connector was a great product advantage. Apple, iPad or iPhone, and now it is becoming available to the general public. This cable can be inserted either way.

We will also mention one more significant advantage over the USB 3.0 standard: due to the maximum transmitted power increased to 100 W, via USB 3.1 in the future without additional source power supply will be able to connect various peripherals such as monitors or speakers. The 5A amperage also significantly shortens the charging time of the mobile phone.

The fact that the connector is called USB Type-C makes you wonder how it differs from previous versions A and B. The first thing that catches your eye is the other appearance... Type-C is more like not a full-fledged USB cable, but the cord with which we charge mobile gadgets.

Left to right: USB Type-C, Lightning, microUSB

Type-C is symmetrical and can be inserted either side. Remember the situations when a flash drive or mouse for some reason is inserted only the third time? This is now in the past. How iPhone owner 5 and Lightning cable I will say that it is very convenient. For example, it is much easier to grope and insert a wire in the dark.

Type-C bandwidth is 10 GB per second. Voltage - 20 V. Six months ago, many IT resources wrote that in the future, using this connector, we will be able to charge laptops in the same way as tablets and smartphones. Apple has turned the future into the present. V new MacBook only one connector - USB Type-C, which acts not only as a port for connecting peripherals, but also as a connector for charging a laptop.

At first it seems like it's insanely cool. Then too. But also there are thoughts that we have not yet managed to become so independent from gadgets with wires. Of course, the adapter that Apple quietly released with the release of the MacBook solves this problem. However, this turns the MacBook from portable device into a laptop with which you need to carry an additional connector everywhere.

Also important is the fact that the adapter costs $ 79. But third-party manufacturers have already started producing their own solutions, so the range will soon become much wider.

Connector for USB Type-C

The bandwidth of USB Type-C allows you to connect to the connector not only standard USB devices, but even HDMI and display the picture from the monitor on a second screen. With Apple often pioneering such engineering and technological innovations, it is possible that Type-C will soon become the ubiquitous solution.

And we need a bunch of adapters.

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 already managed to give us a certain amount of devices that have tried on new interface: 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. The largest manufacturers will continue to wage a fierce battle for the consumer, supplying Type-C connectors not only to their own flagship models but also offers in lower price segments.

If you regularly use external batteries or other portable charging device, sharpened 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 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 items 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 will receive 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 cable for microUSB.

Note that Anker PowerCore + boasts several unique finds that are responsible for legitimately fueling yours. 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 onboard, 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 provides USB interface 3A Type-C.

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.

The Talentcell 10400 mAh power supply is the cheapest 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 indicated 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 don’t have extra funds to buy an expensive “power bank”, Talentcell is ready to offer its services. The reviews from the project 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 10,000 mAh standard USB port and the 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.
