USB type c connector. USB Type-C - what is it and what is it for?

The industry is on the verge of another change. In the coming years, prepare to throw away all your USB and HDMI cables. They will be replaced by an interface USB Type-C. The new format looks brilliant on paper, but... real life There are still a lot of questions for him. The main one is when to switch to it? Now let's figure it all out.

Why is USB Type-C the future?

The situation is obvious. The point is the versatility of the format, which is always a plus. What can regular USB do now? Only transfer data. Separate interfaces (HDMI, VGA, DVI) are required to connect the monitor and charge the laptop, which is inconvenient.

Type-C allows you to do everything at once. In addition to transferring files at speeds of up to 10 GB/s, the interface can broadcast images in 5K quality (5120x2880 pixels), power devices with a consumption of up to 100 W and a voltage of up to 20 V. And all this - at the same time. In addition, the connector itself is small (8.4 x 2.6 mm) and double-sided. Trying to blindly connect a flash drive or charge a smartphone in the dark when the microUSB doesn’t want to fit into the connector will become a thing of the past.

Where did it all start?

The trend was set by Apple, a company that many now criticize for its inability to surprise, or to do it in a very strange way: by introducing innovations that turn into headaches for customers.

In 2015, the Cupertino team introduced the new Macbook. The model was clearly planned to replace Macbook Air, which are already quite boring and outdated. Their TFT matrix screens look especially bad, while other products sport Retina displays. So, in the new Macbook, in addition to the 3.5 mm headphone jack, there was only one output - USB Type-C. Autumn 2016 Apple of the Year showed new generations of Macbook Pro, which already have four similar ports and no other interfaces (only the mini-jack was retained).

Other manufacturers are also catching up: laptops with USB Type-C are produced by HP, ASUS, Dell, MSI. But these companies went more safe method. Along with USB Type-C, their devices also have the usual USB 3.0, HDMI, and an SD card slot. Apple cuts without waiting for peritonitis.

Wait, but Apple introduced Lightning a couple of years ago...

Yes, but this interface is only used on iPhone and iPad. And we are almost sure that the company will completely switch to USB Type-C in smartphones and tablets in a couple of years.

Devices from other manufacturers (Google Nexus 5X and Pixel, ASUS Zenfone 3) have already received new standard. So we have a chance to live until that bright day when any mobile phone, laptop or other gadget can be charged via one cable.

But Apple can't bury Lightning so quickly. When the company announced with the release of the iPhone 5 that the bulky 30-pin connector was a thing of the past, the forums were bursting with user indignation: what to do with purchased docking stations and acoustic systems? Gradually everyone came to terms and switched to a compact interface. But if, five years later, people are again told about a change in format, Apple won’t seem to care enough. In addition, Lightning is their own standard, and it is especially difficult to abandon the native one. It will probably be unified with USB Type-C, as happened with Thunderbolt 3.

What exactly is the problem with USB Type-C?

The problem is not so much in the connector as in the periphery. There are only a few monitors with this interface, and they are not cheap. The same thing with flash drives, hard drives, batteries - they are there, but the choice is very limited.

It is unlikely that many people can completely upgrade their equipment at one time - this will amount to a very decent figure. This means that a Type-C adapter is required. And this is precisely the main problem.

Firstly, you need to buy Type-C adapters, and original adapters, especially from Apple, cost an indecent amount. Get out a calculator: USB-C/Lightning (for connecting to an iPhone/iPad) - 1,590 rubles; USB-C/HDMI, USB-C, USB 3.0 - 4090 rubles; adapter from USB Type-C to regular USB - 799 rubles. You won’t be able to insert a flash drive from a camera into your laptop either - again, get money for an adapter (Sandisk USB Type-C adapter costs, for example, about 1800 rubles). The minimum required set of additional devices will cost 6-7 thousand rubles. True, you can find a real combine that will immediately have USB 3.0, a LAN output, HDMI, and a slot for a memory card.

So while USB Type-C does not make life easier, it only adds problems. For example, photographers cannot quickly transfer pictures from their camera to their laptop. If at work you are asked to write something onto a flash drive, then either carry an adapter with you at all times, or buy a drive with two interfaces (fortunately, there are such), or say apologetically, “I’m here at the peak of progress: only USB- C".

But USB Type-C will inevitably become widespread. It won’t be possible to stubbornly stick to USB 3.0: for another couple of years, manufacturers will definitely release solutions with familiar connectors, but gradually people will be forced to switch to the new standard. Fortunately, it will be cheaper to do this later than it is now.

So should we switch to USB Type-C or what?

The transition to USB Type-C depends on the specifics of how you work with devices. For example, if the laptop is used at maximum mobile gadget, data is transferred between devices via Wi-Fi, and the only wire you connect to it is the charging wire, then you will not have any problems with the new interface.

In extreme cases, you will need to buy one adapter, which has a connector for the usual USB and HDMI. An Apple smartphone, for example, can be connected via USB to this adapter rather than buying a Lighting/USB-C adapter.

But if you need to use many ports at the same time: HDMI, SD card slot, 2-3 USB, you will have to get rid of it. But hardly a large number of users connect so many things to their laptop at one time. In addition, the Macbook Pro, for example, has four connectors at once. By connecting the laptop to the TV, putting it on charge and connecting the flash drive to the triple adapter (for 4090 rubles), you will have three more free ports at your disposal.

Are there cheap adapters for USB Type-C?

Craftsmen from China tirelessly invent cheaper and more universal adapters. But you need to be careful when buying them. Budget options can burn the device when connected by supplying too much current. Adapters from well-known manufacturers are equipped with reliable protection that will prevent the destruction of your smartphone or laptop.

It is better to avoid suspiciously cheap options. Moshi, HyperDrive, Choetech, SanDisk - you can pay attention to the products of these companies. But 100% quality and reliability will be ensured only by branded adapters from manufacturers, and not from third-party brands. By the way, interesting thing produces Griffin - a magnetic charging cable, like in the now old Macbooks. If you touch it, the laptop will not crash to the floor - the cable will simply disconnect, and a small tail with USB Type-C will remain in the laptop.

We draw conclusions:

The future belongs to USB Type-C - that's for sure. I would like to believe that the interface will become widespread soon. But if required frequent connection different devices (flash drives, power banks, monitors, network cables), then don't rush. First, find adapters that suit you completely and estimate their cost, as well as how many adapters you will have to carry with you all the time.

The speed of the interface depends on installed controllers, and you'd be surprised what some manufacturers do with them. USB Type-C technology promises us data transfer speeds of up to 10 Gbps, but the first generation of devices with USB Type-C turns out to be far from that fast. In this article we figure out what's going on here...

USB Type-C is an intriguing new standard that began appearing on laptops, tablets, phones and other devices more than a year ago. And we have long had a desire to check what speed it can actually provide. With the arrival of the SanDisk Extreme 900, we can really push this two-way port to its limits. For testing, we prepared 8 laptops with USB Type-C, and also inserted a special PCIe card into the desktop PC to make the test more complete.

What your USB-C port is silent about

It is implied that USB Type-C will become universal standard port, but today its universality is manifested only in intricacy. USB Type-C can operate at 5 Gbps or 10 Gbps while still being labeled as USB 3.1 by the laptop manufacturer. Technically, USB Type-C can even operate at USB 2.0 speeds - a measly 480 Mbps. So if you see a USB Type-C port, all that can be said is that the interface speed can vary from a modest 480 Mbps to an impressive 10 Gbps.

To confuse things even more, Intel technology Thunderbolt 3 uses the USB Type-C port to transfer data over PCIe. And it also supports USB 3.1 at 10Gbps.

Thunderbolt 3 and support for video transmission over USB Type-C need to be discussed separately, and we will devote another article to this. However, power and not so universal charging via USB Type-C have already been mentioned.

Not all USB Type-C ports are created equal

What's installed on your laptop?

USB Type-C performance is affected by a number of key factors. The first is the capabilities of the hard drive in your PC. If you copy from the built-in hard drive, it is simply impossible to get a speed even close to the speed of the port, simply because most disk interfaces don't reach maximum performance USB Type-C.

Another important factor is the controller used to connect the port. There are two popular chips available in the market today. The first one is ASmedia ASM1142. This USB 3.1 chip, running at 10 Gbps, can be found in many early versions of laptops and desktops that were equipped with USB Type-C. And since we were unable to quickly find a laptop with this chip, we inserted an Atech BlackB1rd MX1 PCIe card into a desktop PC. Performance assembled system should be almost the same as laptops with this chip. Another candidate for leadership is the expensive Intel Thunderbolt 3 chip, which also supports USB operation at a speed of 10 Gbit/s.

And finally, a very popular solution today that can be found in many laptops is a USB 3.0 controller built directly into the chipset system logic Intel. The same chip is used to connect standard rectangular USB 3.0 Type-A ports. Many PC manufacturers simply pass its signal to oval USB Type-C ports. And this solution is the most popular, since it is cheaper and requires less energy. However, it also limits the work of anyone USB port Type-C maximum USB speed 3.0 - 5 Gbit/s.

SanDisk Extreme 900 is one of the first drives to support USB 3.1 10 Gbps

Test Method

To conduct our tests, we used a SanDisk Extreme 900 SSD, which actually supports USB connection Type-C at 10 Gbps. SanDisk was able to create this 2TB drive by combining two M.2 SSD drives into RAID array 0 inside one case. And it turned out to be a really fast USB drive. By connecting it to the USB Type-C ports of each computer, we ran the AS SSD utility, which allows us to evaluate the actual serial data transfer speed of the port.

You can see the results that speak for themselves in the chart below. We have arranged them in descending order of performance. The signatures indicate both laptop models and versions of installed controllers.

We evaluated 8 laptops to examine USB Type-C performance (click on image to enlarge)

It's not surprising that laptop manufacturers who choose the cheapest option (connecting an Intel USB 3.0 5 Gb/s controller to a USB Type-C port) give you... 5 Gb/s performance. We weren't able to test the 12-inch MacBook because the AS SSD doesn't work on OS X, but it uses the same controller. So you have to wait for equivalent performance.

Of much greater interest is the operation of chips with a speed of 10 Gbps: ASMedia and Thunderbolt 3. In the diagram they are represented by 2 Dell XPS models (for Thunderbolt) and an ASMedia card in a desktop PC. In our test ASmedia showed slight advantage over the Thunderbolt 3 controller. However, PC manufacturers confirm these data, citing the results of their own internal tests.

Samsung model Notebook 9 Pro only uses the USB 3.1 portion of the Intel Thunderbolt 3 controller

However, there is another interesting participant in the test - this samsung laptop Notebook 9 Pro. The 15.6-inch model uses the rather rare approach of equipping a USB Type-C port by using an Intel “Alpine Ridge” chip with Thunderbolt 3, but only includes USB support. Even in the Device Manager panel, you will only find the Intel USB 3.1 controller as shown in the above screenshot.

Samsung representatives confirmed that this laptop does not work with Thunderbolt 3. We tested this using an Akitio Thunderbolt 3 drive - indeed it does not work. Why Samsung engineers did this remains a mystery.

However, we do know that performance has been surprisingly poor. Yes, this port is faster than regular USB Type-C with built-in Intel chip, but much slower than ASMedia and full version Thunderbolt 3. Strange move.

Conclusion

One look at the test chart makes it clear that there are real benefits to having a full 10 Gbps USB 3.1 port in your computer. The most obvious conclusion is that you won't have to wait long for files to be copied to a USB drive. But besides this, only with a full-fledged port can you realize all the advantages of an external drive with USB 3.1. And as more and more PC models with USB ports Type-C, we recommend that you read the specifications more carefully before purchasing a computer.

New USB standard Type-C is still not widely developed on the market, but manufacturers are gradually adopting the new technology. In smartphone industry USB-C already can be called a new trend because it is not only an improved charging port, but also a means of eliminating 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 all electronic devices are equipped with a USB connector. From desktop computers to smartphones and various storage devices with laptops. USB is a ubiquitous standard when it comes to connecting peripherals or transferring data between devices. Last thing major update USB came out 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, you can count on one hand the number of devices on the market that use USB Type-C technology. Among computers, these are the latest laptops from Apple, from Google, a line from Samsung and several more hybrid devices. Among the smartphones - mainly the 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 currently actively developing industry data transfer standard for computers and mobile devices. The main and most significant innovation of Type-C is a modified connector - universal, symmetrical, 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 the new USB standard. It also includes the largest technology companies, namely Apple, Samsung, Dell, HP, Intel and Microsoft. By the way, this is important to know, because USB Type-C was easily accepted by most PC manufacturers.

USB-C is the new standard

First of all, you need to know that USB Type-C is a new industry standard. Just like they once were USB 1.1, USB 2.0, USB 3.0 or the latest USB 3.1. Only 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 connector design in a similar way to technology modifications - MicroUSB and MiniUSB. However, the decisive difference is in this case is that, unlike MicroUSB and MiniUSB, Type-C is aimed at replacing absolutely all standards, on both sides (example USB-MicroUSB).

Main characteristics:

• 24 signal pins
• USB 3.1 support
• Alternate mode for implementing third-party interfaces
• Speed ​​up to 10 Gbps
• Power transmission 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. USB 3.1 can also 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 a new Type-C universal connector.

USB versions

To better understand why Type-C will become a replacement for traditional USB versions, it is first necessary to understand the difference between them. Exist different versions USB, as well as even different connectors - for example, Type-A and Type-B.

USB versions belong to a common standard, but they differ in the maximum data transfer speed and operating power. Of course, there are many other factors.

USB 1.1
Although USB 1.0 is technically the first version of USB, it 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 12 Mbps and consumes 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 maximum data transfer speed - up to 480 Mbit per second. USB 2.0 has also 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 was marked blue to valiantly distinguish it from older generations of USB. USB 3.0 can operate at speeds of up to 5 Gbps, using 5V at 1.8A for its operation. By the way, this version was presented in November 2008.

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

Type-A
Type-A is the classic USB interface. The short and rectangular plug became original design for USB remains to this day the standard connector for use at the host end of a USB cable. 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 complex nature of the socket. Currently, both of these Type-A variations are considered obsolete.

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

Type-C
So, after Type-A and Type-B, we come, obviously, to the newest Type-C. 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, since USB-C involves a complete replacement of outdated USB connection technologies. Also Type-C was developed in a special way, to additional options like Mini or Micro did not need to be released at all. This, again, is due to the intentions to replace all current connectors with USB Type-C.

Main feature Type-C standard is the versatility or symmetry of the connector. USB-C can be used by both sides like technology Apple Lightning- no more special sides for connection, which are also difficult 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 backwards compatible with existing options USB, but for this use case, of course, you will need adapters.

Disadvantages of USB Type-C

Naturally, 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 the physical design of the connector - it is very fragile due to its symmetrical design. Apple, despite the same versatility of its Lightning, uses a durable metal plug that is much more resistant to external influences.

Even more pressing and of significant concern USB problem Type-C is an unregulated connector, which has led to a number of dangerous accessories being sold. Some of these accessories, by using unsupported voltage levels, can fry the connected device. For example, this was the case with the flagship, which was magnificent at the start, which subsequently began to first ignite and then completely explode in the hands, trousers, cars and apartments of its owners.

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

Minuses:

• Design. The design of USB Type-C is good, but the design has suffered - it is quite fragile. Apple uses an all-metal plug in its Lightning, while Type-C uses an oval shape with the signal pins placed in the central part.
• Connector operation. Allowing USB Type-C to operate at unsupported voltage levels will likely cause the cable and/or device to catch fire.
• Compatibility. USB Type-C is an innovation in the USB world, but newest 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 additional adapters. This is an additional waste of money.

Benefits of USB Type-C

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

Pros:

• Symmetry. USB Type-C allows you to forget about situations where you have to remember which side to insert the cable into the connector. Also, from now on you don’t have to worry about not finding the right side of the USB in the dark.
• Compactness. The dimensions of USB Type-C are 8.4x2.6 mm - this allows manufacturers to make computers and mobile devices much thinner.
• Versatility. Thanks to the integration of a single connector, it will become possible charging with one cable for both a laptop, a tablet or a smartphone.

Take a look at almost any laptop and you'll find a number of different ports gracing its sides: USB, HDMI, power connection, and a few others. Soon this may become a thing of the past, as manufacturers such as Apple, HP and are already ready to accept the new universal standard, offering increased speed, improved functionality and convenience. The time of USB-C is coming, and its future looks very promising.

One cable, many uses

The idea behind USB Type-C is simple. You have one type of cable, one type of port, and through them you connect everything you need. This means that you can use the same connector for hard drives, monitors, audio interfaces, smartphones, tablets and even for charging a laptop.

Nowadays, most peripherals connect to a PC via USB-A. It has a rectangular shape and is used on USB flash drives, external keyboards, mice, hard drives and on almost all other devices.

On the opposite side of the cable, there is usually another type of connector, such as Micro USB for connecting to smartphones, Mini USB for other gadgets, Micro USB-B for connecting to some storage devices, or square-shaped USB-B used in printers. The difficulty is that you need to have a separate cable for each device, and there is no guarantee that if you are somewhere else, you will be able to find exactly the one you need.

USB-C simplifies this situation by establishing one standard format for all devices, and even the same connector on both ends of the cable. The slim, oval-shaped connector is smaller in size than previous USB formats. Plus, it's also symmetrical/reversible like Apple's Lightning connector - hence the times you were fiddling with the cable to find The right way connections to your device will soon become a thing of the past.

Co USB-C time, will likely become the only universal port for all devices, replacing the USB-A, USB-B, Micro USB and Mini USB that make our lives so difficult now. All cables will be the same and will fit all devices. Admittedly, this will not happen very soon, since most peripherals on the market still use the old connection types. But with the release of the new line MacBook Pro from Apple, equipped exclusively with USB-C ports, Asus Zenbook 3 and HP Specter, which use the same approach, USB-C ports are becoming a common option on many modern laptops and 2-in-1 devices. This undoubtedly indicates that the future lies with the new platform.

What are the benefits of USB-C?

Of course, simply changing the design of the connector and port is unlikely to be a compelling reason to upgrade your entire peripheral, but this is not the only advantage of USB Type-C. The new format also supports the latest USB protocol 3.1, which is faster and more versatile than previous versions, used on devices with USB type A.

• Speed. When USB 1.0 was introduced back in 1996, it had a maximum data transfer speed of 12 MB/s. USB 2.0, which followed in 2000, “jumped” to 480 Mb/s. USB 3.0, which replaced it in 2008, provided a significantly improved performance of 5 Gb/s. Now USB 3.1 has doubled that figure, offering as much as 10 Gb/s and a number of additional benefits.
• Performance. These additional benefits include the ability to deliver up to 100 watts of power to connected devices, which is enough to charge any smartphone, tablet and almost any laptop. The new format can also carry 4K monitors and audio.
• Compactness. The smaller size and versatility of the ports means they will now become ubiquitous on ultra-thin laptops and Android smartphones such as the Google Pixel.
• Versatility. The universal nature of the new standard opens up a number of useful practical applications with just one cable. For example, a user can connect their USB-C-equipped laptop to an externally powered display and charge while watching video content. If other USB devices are connected to the monitor, for example, external drive, PC can also access it and transfer files. In addition, the cable can be used to connect and charge your smartphone.
• Compatibility. USB Type-C has backwards compatible with previous generations. If you have an adapter or dongle, you will be able to use your USB devices over USB-C. To meet this need, a number of interesting accessories, such as the Targus Dock 410, which offers not only three USB 3.0 ports, but also HDMI, Gigabit ethernet And various videos options. The fact that the device can manage this entire range of functions through a single USB-C port shows the potential of the platform - it's not for nothing that more and more modern laptops, for example, Apple's line of thin 12-inch MacBooks are equipped with a single port. Now there is an even faster form of USB Type-C, which also includes support for Thunderbolt 3.0. With it, devices like the MacBook Pro, Dell XPS 13 and HP Specter can reach speeds of up to 40 Gb/s - four times faster than USB 3.1. With increased data transfer speeds, users can connect USB-C cable to the aforementioned Targus Dock 410 and run two external displays with resolutions up to 3840x2160 by connecting them to the DVI-D and HDMI ports on the dock. Since the standard is still new, manufacturer specifications may vary between devices - so consumers need to ensure that accessories like the Dock 410 are compatible with their laptops.
• Reversibility. Who has never cursed while trying to get a Micro USB connector or even a standard USB connector into a device correctly? Apple's Lightning connector eliminates this inconvenience, and now USB-C is just as convenient.

What are the disadvantages of USB Type-C?

While USB-C is a shiny new format that will no doubt become ubiquitous in the near future, it is currently still in its infancy and therefore not without some confusion and dangers.

Since USB-C refers to a connector type rather than an internal specification, users may be unpleasantly surprised that their device isn't as fast as they expected. The first generation of USB-C uses USB 3.0 technology, which has a maximum speed of 5 Gb/s, while the second generation of USB-C supports USB 3.1, which provides 10 Gb/s. There is also a third generation that includes Thunderbolt 3 (for example, on new MacBooks Pro), with maximum speed up to 40 Gb/s. The problem with each of the ports is that they look the same, but the manufacturers use various components in their model lines. Therefore, to avoid disappointment, potential buyers You should check the specifications and speed of the connector before purchasing.

Cables can also be confusing as they all look the same but have various options performances that affect their capabilities. If you need a charging cable, you'll need to make sure it supports USB Power Delivery, and for HDMI, MHL, or DisplayPort, you need a USB-C cable with Alt Mode functionality. These inconveniences will undoubtedly be eliminated in the future, but at this stage The buyer should check all details carefully.

The main problem facing USB-C is cheap cables and accessories that can cause physical damage to the device. The problem is caused by the amount of energy they are capable of transmitting. This can be dangerous not only for devices, but also for people. Therefore, you should not purchase cheap, non-branded products from China, but choose reliable, proven brands.

USB Type-C isn't exactly a new concept for Android fans, but there are some who are still in the dark about this technology. In this article, we will find out what USB Type-C is and get some recommendations on how to use it.

USB (Universal Serial Bus) is a cable standard that allows you to transfer data and power between electronic devices. It first appeared in 1998 and has gone through several iterations since then, the most recent being USB Type-C.

Each version of USB has data transfer speeds and limits on the amount of electrical current through it. The previous USB Type-A and Type-B connectors only have four pins, but USB Type-C has 24, more and more high speed data transmission.

For example, Micro-USB 2.0, which is currently found on Android Android smartphones, supports 5V (volts)/2A (amps) power and 480Mbps data transfer rates. USB 3.1 Type-C, on the other hand, has 20V/5A power with transfer speeds up to 10Gbps.

What are the advantages of USB Type-C

Type-C has several others useful functions. The USB Type-C connector is reversible, meaning it will work no matter the orientation you plug it in, and has an identical pin on both ends.

What's more, the next generation of HDMI is USB Type-C compatible, meaning there is no need for a separate dongle to send audio/visual data high definition. In the future, laptops will no doubt fully embrace USB Type-C.

What are the disadvantages of USB Type-C

Not all manufacturers are adapting to the new USB standard. Some USB Type-C cables follow the USB 2.0 standard, which is a dangerous practice and may damage your smartphone.

If you need to buy a Type-C cable for your phone, you can purchase one from your device manufacturer at this time.

Another one a big problem, is the number of devices that use it. Nektus 5X, good luck finding a cable. Another disadvantage is that quality cables And charging device USB Type-C is expensive.

Beware of cheap USB Type-C cables, they can harm your phone.

Even if your smartphone has USB Type-C, it may not support USB 3.1 unless you check to see if it has it before purchasing. Always use the cable supplied with USB device Type-C
