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 a different 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, it can be inserted in any direction. Remember situations when a USB flash drive or mouse for some reason is inserted only the third time? Now it's in the past. As the owner of an iPhone 5 and a Lightning cable, I can say that this is very convenient. For example, groping and inserting a wire in the dark is much easier.
Type-C bandwidth - 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. The new MacBook has 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 there are also 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 introduction of the MacBook solves this problem. However, this turns the MacBook from a portable device into a laptop with which you need to carry an additional connector everywhere.
The fact that the adapter costs $79 is also important. But third-party manufacturers have already begun to produce 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 not only standard USB devices to the connector, but even HDMI and display the image from the monitor on the second screen. Considering that Apple is often a pioneer in such engineering and technological innovations, perhaps soon Type-C will become a ubiquitous solution.
And we need a bunch of adapters.
Is it really time for one unified connector to charge any device? More recently, such an assumption could be ridiculed. But even Apple is slowly giving up, and the MacBook with its USB Type-C is the first confirmation of this.
It is still far from nirvana, first you need to finish the periphery. First things first: before talking about the problems of the new port, you need to remember what kind of "beast" it is.
One ring One connector to rule them all
The idea of the USB Type-C connector is to replace all the others, whether it's charging, an HDMI port, or a regular socket for a USB flash drive. No more "I have the cord on the other side" or "I can only connect one monitor." I found the port, inserted the device, everything worked. Idyll.
Oh well. In practice, this "freedom" has created a lot of confusion. It is not enough to make a universal connector - it needs at least universal cable.
The fact is that the USB Type-C port has 24 pins, through which a breakthrough of signals of different protocols pass. That's what can be put into this universal connector.
- USB 2.0
The first devices equipped with a USB Type-C port actually worked in USB 2.0 mode and transferred data at a speed of 480 Mbps. Tablets and smartphones using this protocol are still found (hello, Nokia N1).
- USB 3.1 gen 1 (3.0, SuperSpeed USB)
It flies at speeds up to 5Gbps and is backwards compatible with USB 1.x and USB 2.0. Most likely, the blue port in your computer works with this protocol. MacBook is no exception.
- USB 3.1 gen2
The upgraded version of USB 3.0 is also backwards compatible. The data transfer rate has increased to 10 Gb / s, and the power to 100 watts. Almost like Thunderbolt!
- Alternate Mode (AM)
The Type-C connector can accommodate other non-USB protocols. For example, Thunderbolt, HDMI, MHL or DisplayPort. But not all peripherals understand this Alternate Mode.
- Power Delivery (PD)
The most delicious thing is charging via USB Type-C. Power Delivery supports 5 standard power profiles - up to 5V/2A, up to 12V/1.5A, up to 12V/3A, up to 12-20/3A and up to 12-20V/4.75-5A. Compliance with any profile is determined automatically.
- Audio Accessory Mode
Yes, analog audio can also be sent through the USB Type-C ports.
The hardest part is finding the right wire.
Ok, everything is clear with the port, it remains to buy a cable. But beginners usually face three problems:
1. Old protocol in a new connector
"New" USB Type-C cable for 150 rubles from Aliexpress? Beware, an ancient USB 2.0 may be hiding inside. It's not even about the reputation of Chinese entrepreneurs, many well-known brands are ready to sell a Type-C cable with an old protocol inside at a bargain price.
2. A bunch of specifications
Yes, everything is signed in the title. But how to understand the average person who does not care about all these new specifications? Which picks up the wire according to the shape of the connector? No way. He just understood the difference between USB 2.0 and 3.0 wires.
Yes, and outputting an image via USB Type-C is not an easy undertaking. In addition to Display Port and HDMI, there are three more generations of Thunderbolt that can also connect monitors. It is not enough to find a suitable cable - the device must clearly understand that it is connected to it through Alternate Mode.
3. Will it charge?
It will be if the name contains "charge" or "PD". But there is a catch here too: a cable that supports charging via USB Type-C must meet the required profile and be certified. What is fraught with? At best, slow charging, at worst - by igniting the device.
Why you can not insert the first cable that comes across
Because everything can be messed up. Here are three reasons:
1. Low data rate
Of course, to connect to an external hard drive or smartphone, almost any wire with the right connectors will do. But you should make sure that it works with the right protocol (for example, with USB 3.0), otherwise the data transfer speed will drop.
2. Bad picture or its absence
If the cable will connect the MacBook and the monitor, make sure that the wire transmits the signal at the correct frequency. Don't forget that Thunderbolt 3 doesn't work with previous generations.
3. 100 W current is no joke
With PD cables, it's a bit more complicated. The power threshold was raised - which means you need to be more careful, because in the event of a cable marriage, sad consequences are possible. Not so long ago, a man’s laptop and a couple of other devices burned down. Of course, this is an isolated case, and it is unlikely that your MacBook will burn down. But over time, the battery or power controller may suffer.
So, if you need a wire to charge your laptop, forget about nonames for two hundred square meters.
But for smartphones with USB 2.0 adapters, not everything is so scary. You can buy any USB Type-C - USB 2.0 cable and quietly charge your phone.
What to do?
Of course, USB Type-C is the future. There are more and more devices with new connectors and the time will soon pass when you took the first wire that came across without thinking.
Labels must be glued on USB Type-C cables. Seriously, how else to distinguish deshmansky, for external hard, from expensive, which can be used to charge any device?
The best option is to use original wires. Well, if you really buy, then only cool USB 3.1 with Power Delivery support. These cost $1,500 and up. With connectors from Alternate Mode, the situation is simpler, but the price tag is about the same.
It would seem that the USB Type-C standard has just begun to earn a reputation in the world of mobile technology, but 2015 has already managed to give us a certain number of devices that have tried on a new interface: memories of OnePlus 2, Nexus 5X and Nexus 6P are still fresh.
There is no doubt that this year the number of such devices will continue to grow. The largest manufacturers will continue to fight fiercely for the consumer, supplying Type-C connectors not only to their flagship models, but also to offers in lower price segments.
If you regularly use external batteries or other portable chargers designed for microUSB, it will add to your headache: in order to continue to benefit from your favorite accessories, be prepared to fork out a dozen different adapters.
But there is an alternative option - an 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: replenishing the charge of 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 types of portable chargers. Looks like it's time to figure out which products 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 listed 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.
Anker PowerCore+ with a capacity of 20100 mAh will cost you about $51. For this money, you will get a device with an 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 legitimately fueling your . Proprietary PowerIQ technology copies the charging protocols of each connected gadget, making the procedure safe and as efficient as possible. VoltageBoost will also be useful: it determines the resistance of the cable, thereby ensuring the stability of the process. Unfortunately, Anker PowerCore+ does not support Qualcomm Quick Charge 2.0 technology.
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. The Power Bank itself and a USB/USB Type-C cable are included. There is also an 18 month warranty. The device is charged both via microUSB and via the USB Type-C interface.
In fact, CHOETECH does not look very impressive when compared to Anker's model. It costs $20 less, but along with the price, half the capacity is lost somewhere. 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 a RAVPower power bank with a capacity of 20100 mAh is approximately $60. Inconspicuous design - a black box with a four-point LED indicator - contrasts brightly with excellent functionality: a microUSB connector responsible for recharging RAVPower; another USB port is ready to cooperate with Qualcomm Quick Charge 2.0 and 3.0 technologies; The speed is provided by the USB 3A Type-C interface.
A peculiar "chip" of the battery is the iSmart port. With it, RAVPower recognizes the type of connected device and optimizes its work based on the information received.
It is noteworthy that the claimed 20100 mAh should be enough to bring the Galaxy S6 back to life five times; to restore the full charge of the iPhone 6S, you will have about 8 attempts. RAVPower is also able to protect your device from overcharging and preserve the health of its sensitive microcircuits.
All in all, RAVPower is a great choice for those who want a large portable battery with tons of extras and Qualcomm's Quick Charge support. What else can I say, a luxurious thing with no less "luxurious" price.
Talentcell's 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 displayed by a small LED indicator. In the package you will find a Power Bank and a cable with Type-C connectors. You can use Talentcell with any gadget, except for the handsome 12-inch Macbook. And this wonderful battery allows you to simultaneously charge two smartphones.
If you do not have extra funds to buy an expensive power bank, Talentcell is ready to offer its services. The reviews of the project are quite good, but if you are still confused by a little-known brand, consider 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 is compensated by the possibility of "mega" fast charging from 0 to 100 percent in 3.5 hours.
It seems to us that it’s better to take TalentCell and eat, but it’s still worth considering an additional option - fast food is a harmful thing.
The new USB Type-C standard is still not widely developed in the market, but manufacturers are gradually adopting fresh technology. In smartphones, USB-C is already a new trend, because it is not only an improved charging connector, but also a means to do away with 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 a variety of drives with laptops. USB is the ubiquitous standard when it comes to connecting peripherals or transferring data between devices. The last major update to USB came in 2013 with the release of USB 3.1, accompanied by the release of the 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 the fingers of devices using USB Type-C technology. Among computers, these are the latest laptops from Apple, from Google, a line from Samsung and several other hybrid devices. Among 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 rapidly evolving industry standard for data transfer for computers and mobile devices. The main and most significant innovation of Type-C is a modified connector - universal, symmetrical, capable of working with 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 has been easily adopted by most PC manufacturers.
USB-C is the new standard
First of all, you need to know that USB Type-C is the new standard for the industry. Just like they used to be 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 speed and various other improvements, while Type-C physically changes the design of the connector in a similar way to technology modifications - MicroUSB and MiniUSB. However, the decisive difference in this case is that, unlike MicroUSB and MiniUSB, Type-C aims to replace absolutely all standards, and on both sides (example USB-MicroUSB).Main characteristics:
- 24 signal outputs
- 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 possible question for the uninformed about USB Type-C might 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 - such a port is called USB 3.1 Type-A. But today it's much easier to meet USB 3.1 with a new Type-C universal connector.USB versions
To better understand why Type-C will become a replacement for traditional versions of USB, you first need to understand the difference between them. There are different versions of USB, as well as even different connectors - for example, Type-A and Type-B.USB versions belong to a common standard, but their difference lies in the maximum data transfer rate and power of operation. Of course, there are many other factors as well.
Although USB 1.0 is technically the first version of USB, it failed to fully reach the market. Instead, a new version of USB 1.1 was released - just it became the first standard to which we are all accustomed. USB 1.1 can transfer data at 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 release of USB 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 - the new version of the standard was designated blue to valiantly distinguish it from older generations of USB. USB 3.0 can operate at speeds up to 5 Gbps, taking 5V at 1.8A for its operation. By the way, this version was presented in November 2008.
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 up to 10Gbps throughput with a maximum power consumption of 5V/1A, or optional 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 they have never been widely accepted by the public due to the complex nest. Both of these Type-A variants are now obsolete.
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 on printers, although it is itself an extension of the USB 3.0 standard to introduce new connectivity options. The classic MiniUSB and MicroUSB are also available in the Type-B version, along with the absolutely clumsy MicroUSB 3.0, which uses additional plugs.
Type C
Thus, after Type-A and Type-B, we obviously came to the latest Type-C. The Type-A and Type-B versions were supposed to work together with each other through backwards compatibility, but the arrival of Type-C completely ruined these plans, since USB-C implies a complete replacement for obsolete USB connection technologies. Also, Type-C was designed in a special way so that additional variants such as Mini or Micro would not need to be released at all. This, again, is due to the intentions 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, similar to Apple's Lightning technology - no more special sides for connection, which, moreover, 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 of the latest version, including the highest speed.
USB-C is still backwards compatible with existing USB variants, but adapters will of course be needed for this use case.
Disadvantages of USB Type-C
Problems with the new USB Type-C standard, of course, also exist. 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 the symmetrical design. Apple, despite the same versatility of its Lightning, uses a durable metal plug that is much more resistant to external influences.An even more recent and significant problem with USB Type-C is the unregulated operation of the connector, which has resulted in a number of dangerous accessories being sold. 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 great at the start, which subsequently began to ignite 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 USB Type-C accessories. So, if the accessory does not meet the standard specifications of the USB Implementers Forum Inc., then the product will not be allowed to be sold. Also, to check the working status and authenticity of various third-party accessories, USB-IF has introduced 128-bit encrypted software that will allow devices with this connector to automatically check the 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 signal pins in the center.
- Connector work. Allowing USB Type-C to operate at unsupported voltage levels is likely to result in a fire hazard to the cable and/or device.
- Compatibility. USB Type-C is an innovation in the world of USB, but the newest generation leaves older devices behind because they don't support 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, higher data transfer rates and 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 to transmit video. So USB Type-C will replace the connectors familiar today and become the universal standard in any situation.
Pros:
- Symmetry. USB Type-C allows you to forget about situations when you have to remember 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 USB in the dark.
- Compactness. USB Type-C dimensions 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 be possible to charge both a laptop and a tablet or smartphone with a single cable.
The rapid development of computer technology affects not only the main components of systems. Opportunities are increasing, including various interfaces. As for the most common way to connect peripherals - USB - here, in general, we can state a multiple increase in performance in recent years. The bandwidth of the universal serial bus is increasing, the functionality is expanding. The connectors used to connect a variety of USB devices are also subject to change. Today, many people hear about USB, what are the advantages and disadvantages of the solution - the topic of this article.
Modern computer connectors
Looking around the case of almost any laptop, you can find a number of different ports located on the sides. Among them, USB is always present, almost always HDMI and some others. Modern models are often equipped with the latest USB Type-C port. What kind of connector this 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 a new way of pairing a computer and peripherals. The USB Type-C port offers users increased data transfer speeds, improved functionality, and a new level of usability. In short, the future of the standard looks very promising.
Many uses for one cable
The creators of USB Type-C used a very simple idea when developing the standard. The user must have a single type of cable, and his computer equipment is equipped with one type of port. Through the use of a unified interface, anything is available to connect. For example, using a USB Type-C cable, you can connect inherently 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 the 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 flash drives, external keyboards, mice, hard drives, printers and many other devices with PCs and laptops. Such a monopoly is likely to be broken soon - the USB Type-C cable already occupies a worthy place among the solutions used to connect many devices.
Concept change
Various cables are used to connect devices to the now standard USB-A port. The main difference between them is the connector located on the opposite side of the cable connected to the computer. It is almost always a different type of connector. For example, micro-USB is used for smartphones, mini-USB is often used for other gadgets. To connect a printer, you need a USB-B cable, and to connect storage devices, you need a micro-USB-B cable. Such a variety causes some inconvenience and difficulties, 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, i.e. the universal USB Type-C cable greatly simplifies this situation.
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 is it exactly? The solution is a thin oval-shaped connector that is significantly smaller than previous cable and connector formats of this type. In addition, USB 3 Type-C received the most important characteristic represented by symmetry and reversibility. In general, it is very similar to Apple's Lightning solution - very convenient, because you do not need to spend 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 make life so difficult for ordinary users today. All cables should be the same and be able to be used for any device. Of course, quick unification will not happen, too many operable devices with connectors other than USB Type-C are used today and will be in operation for several more years.
At the same time, 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 that flagship devices from the most famous brands equipped with the port in question are coming out suggests that the described situation, i.e. the displacement of outdated connectors from the market, will come sooner or later. For compatibility with older solutions, for now, you will have to use a USB Type-C adapter.
Compatibility
After reading the above, you can think about what to do with devices already purchased that are equipped with connector types other than USB Type-C. Needless to say, 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 like mini-USB - Type-C, micro-USB - Type-C and others are already widespread and perform their functions perfectly. The principle of security used in computer technology for many years, no one is going to violate. If a new laptop or computer has a USB Type-C port, an adapter for other types of connector is a completely applicable and effective solution.
Learn more about connector benefits
Of course, a simple redesign of the connector and port will not be a good reason to encourage 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 latest USB 3.1 protocol, which offers increased data transfer speed and greater versatility compared to previous versions used on devices equipped with USB-A.
Speed
More than two decades have passed since the introduction of the first version of the connector. At that time, the maximum data transfer rate was 12 Mb/s. To date, it can be argued, considering USBType-C, that this is the fastest 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, include performance, represented by the ability to provide power transmission up to 100 watts. This indicator is enough to provide energy for almost any laptop, not to mention smartphones, tablets and other gadgets. In addition to energy, the new format supports the transfer 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. A lot of useful functions can be provided with a single cable. For example, you can connect a USB-C equipped laptop to an externally powered monitor and charge the laptop battery while watching video content. When storage devices, such as an external drive, are connected to the display, the information stored on the storage media can be accessed from the laptop.
Disadvantages of USB Type-C
This connector is a brilliant new format that no doubt claims to be a ubiquitous solution in the very near future. At the same time, the initial stages of distribution and development, at which the standard is still at the moment, do not provide a complete absence of dangers, as well as 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. Due to the large amount of power transferred through USB Type-C connectors, using cables of poor quality can 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 frustrating moment that users of USB Type-C today may encounter is due to the fact that the standard in question refers more to the type of connector used than to the specifications of the interface itself. Therefore, it is quite likely that the device connected to the 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 of USB-C supports the 3.1 standard, the data transfer rate through which already reaches 10 Gb / s. Problems with each of the ports arise because they look the same, but in the production of ready-made solutions, brands use different components, even in lines of similar models. In other words, before buying a device with a USB Type-C connector, you need to check that the actual technical characteristics of the port correspond to the required indicators.
