Why is it dangerous to insert anything into USB Type-C? The MacBook will burn out. USB Type-C - what is it? Connector type, cable USB type c charger buy

Mobile device users had a hard time in the 2000s - they were forced to put up with the so-called proprietary. The phones of each manufacturer were equipped with unique charging connectors - as a result, the charger, for example, for Nokia did not work with a Motorola phone. It even got to the point of absurdity - when for two phones from the same manufacturer (Finnish) we had to look for different chargers. The dissatisfaction of users was so strong that the European Parliament was forced to intervene.

Now the situation is completely different: almost all smartphone manufacturers equip their gadgets with ports for chargers same type. The user no longer has to buy a new charger “in addition” to the phone.

USB cables can be used not only to transfer data from a PC to a gadget, but also to charge a mobile device. Smartphones are capable of replenishing battery “reserves” both from an outlet and from a computer, but in the second case, charging will take significantly longer. Traditional USB cable for Android smartphone or Windows Phone as follows:

There is a standard plug at one of its ends USB 2.0 Type-A:

This plug plugs into the USB port on your computer or laptop.

At the other end of the wire there is a plug microUSB.

It is, accordingly, inserted into the micro-USB connector on the mobile device.

Micro-USB 2.0 is now a unified connector: you can find it on smartphones and tablets from almost all manufacturers mobile technology(except Apple). An agreement on interface standardization was signed in 2011 by representatives of 13 leading companies in the mobile market.

The choice fell on Micro-USB for a number of reasons:

  • The connector is compact. Its physical dimensions are only 2x7 millimeters - this is about 4 times smaller than USB 2.0 Type-A.
  • The plug is durable– especially when compared with the Nokia thin charger.
  • The connector is capable of providing high data transfer rates. Theoretically, the transfer speed via Micro-USB when using the 2.0 standard can reach 480 Mbit/s. The actual speed is much lower (10-12 Mbit/s in Full Speed), but this rarely causes inconvenience to users.
  • The connector supports OTG function. We'll tell you more about the benefits this provides later.

Micro-USB could impose competition in the fight for the role of a standard connector Mini-USB. The mini plug looks like this:

This type of USB connector was not suitable as a standard one, and here's why:

  • The connector is larger in size– albeit not by much. Its size is 3x7 millimeters.
  • The connector is quite fragile– due to the lack of rigid fastenings, it becomes loose very quickly. As a result, transmitting data via cable becomes a real pain for the user.

In the 2000s, a mini-USB connector could be found on smartphones from “second-class” manufacturers - say, Philips And Alcatel. Nowadays you won’t find mobile gadgets with a mini-jack on the market.

In addition to the USB connectors we mentioned (Micro-USB, Mini-USB, USB Type-A), there are others. For example, micro-USB standard 3.0 can be used to connect to PC hard drives, A USB Type-B(square shape) – For musical instruments(particularly MIDI keyboards). These connectors are not directly related to mobile technology (except for Galaxy Note 3 c USB 3.0), so we won’t talk about them in more detail.

What types of USB cables are there for smartphones?

Thanks to the inexhaustible imagination of Chinese handicrafts, mobile technology users can buy cables of completely different configurations. For example, in the era of proprietaryism, the following “monster” was incredibly popular:

Yes, this charger fits all the main connectors!

Similar “multi-tools” are still on sale, but they have fewer plugs. Here is a 4-in-1 charger, which can be ordered for less than 200 rubles:

This charger is equipped with all modern plugs - Lightning, 30Pin (both for iPhone), microUSB, USB 3.0. Definitely a “must-have” for the user!

There are other interesting options. Here is the cable from OATSBASF For those who hate cables:

This cable allows you to charge two mobile devices from your computer. simultaneously(for example, the 5th iPhone and Android) and has a very tempting price - just over 100 rubles.

In domestic stores and showrooms, the user, of course, will not find such an abundance of different cables as on the pages of catalogs GearBest And AliExpress. In addition, data equipment at retail costs significantly more. For these two reasons, users are recommended to order USB cables from China.

What is the OTG standard?

Surely many have seen such a cable and wondered what it is for:

This is a cable OTG; at one end there is a plug micro-USB, on the second – connector USB 2.0, "Mother". Using such a cable, you can connect a USB flash drive to your smartphone or tablet, but only if you mobile device supports standard OTG.

OTG(short for On-The-Go) is a function designed to quickly connect 2 USB devices to each other, without the mediation of a computer. Connect by OTG you can use not only a flash drive (although this is, of course, the most common case), but also, for example, a computer mouse, keyboard, external HDD, game steering wheel, joystick. You can even connect your smartphone to a printer or MFP to print out a photo taken with the gadget’s camera.

Cables OTG for the iPhone have also already appeared, however, you can only download photos and videos to an Apple device (without jailbreak) from an external storage device - and then only when the root folders on the flash drive and the photos themselves have the “correct” names.

A complete list of smartphones that support the function OTG, no - simply because almost everyone can boast of having this standard modern gadgets and the list would be huge. However, a buyer who intends to connect a mouse or flash drive to the device should inquire from a store consultant about support OTG before giving away money - “just in case.”

USB Type-C: what are the advantages?

Transition from micro-USB This is a new trend in the mobile electronics market! Manufacturers are actively mastering the technology and equipping their flagship models with improved connectors for charging and data transfer. USB Type-C waited a long time “in the shadows”: the connector was created back in 2013, but only in 2016 did market leaders pay attention to it.

Looks like USB Type-C So:

What are the advantages? Type-C in front of everyone familiar micro-USB?

  • High data transfer speed. Bandwidth Type-C equals 10 Gb/sec (!). But that's only throughput : in reality, only owners of smartphones with the standard can count on such speed USB 3.1- For example, Nexus 6P And 5X. If the gadget uses the standard USB 3.0, the speed will be around 5 Gb/sec; at USB 2.0 Data transfer will be significantly slower.
  • Fast charging. The duration of the smartphone charging procedure depends on the potential number of watts supplied by the connector. USB standard 2.0 capable of serving everything 2.5 W– that’s why charging lasts for hours. Connector USB Type-C provides 100 W– that is, 40 times (!) more. It is curious that current transmission can occur in both directions - both to the host and from it.
  • Connector symmetry. If the connector micro-USB there is up and down, then the connector Type-C symmetrical Which side you insert it into the connector does not matter. From this point of view, technology USB Type-C similar to Lightning from Apple.

Dignity Type-C The size of the connector is also small - only 8.4 × 2.6 millimeters. According to this technology criterion micro-USB And USB Type-C similar.

U USB Type-C There are also disadvantages, one of which is more than significant. Due to the unregulated operation of the connector, charging can easily “fry” the mobile device. This probability is not purely theoretical - fires have occurred in practice. It is for this reason that the proliferation of non-original, “makeshift” cables and chargers USB Type-C Type-C and decide to abandon the standard connector. At the same time, Ravencraft admits that, perhaps, complete replacement USB-A will never happen.

Recently, more and more buyers prefer smartphones with Android based with support for the new power port – USB Type-C. microUSB port on this moment is in 1st place for use by manufacturers electronic devices, second place belongs to USB-C.

USB-C not only allows you to charge your smartphone faster, it can be inserted on either side, which is very convenient.

This topic raises many questions regarding the security and efficiency of using the new generation port, so this article contains answers to frequently asked questions regarding USB Type-C.

We've been using microUSB for quite a long time. This allowed many to avoid the need to buy additional chargers and cables for different gadgets (as long as all gadgets used this port).

When equipping devices with a USB-C port, we take into account the fact that it allows you to connect to any computer. USB-C can completely replace microUSB, miniUSB and rectangular USB-A port, which is used in laptops and computers.

Not everyone knows that the new port is more universal than other analogues existing today. USB-C demonstrates faster data transfer speeds between devices and charging speeds. Using a modified port is a step forward. Considering that a huge number of gadgets with different types USB, this port will slowly but surely win the attention of users.

Will the battery charge faster using USB Type-C?

The answer is clear - yes! Let's figure out how it works. USB-C has significantly more power and speed than other cables used for smartphones and tablets. For example, Google's Pixel C tablet has such a cable and is equipped with a 15W charger that charges much faster than USB 3.0 charging. The Pixel 2 Chromebook from the same manufacturer is equipped with a 60W charger, using which for 15 minutes will provide 2 hours of productive work. MicroUSB is not capable of providing such impressive performance.

In the case of smartphones, using the Nexus 6P and Nexus 5X as examples, the charging speed using the 3.0 port and USB-C differs slightly (within 5-10 minutes). Therefore, there is no big difference in this case. When it comes to laptops and tablets, things get a lot more interesting.

What types of cables are there? USB-C

To help you be as productive as possible, most tablets and laptops that come equipped with USB-C come with a pair of cables. One has a USB-C port on both ends, and the other has a USB-C port on one end and a rectangular USB-A on the other end. You get the ability to connect to any device, as well as the fastest charging and data transfer speeds using USB-C cable on both ends.

Why haven't all gadget manufacturers switched to USB-C yet?

It is known that the release of smartphones and tablets is planned in advance. Therefore, not all manufacturers managed to switch to the new port format. Manufacturers had to choose one between the two options, or leave old port, or indulge in overproduction and lose funds. For example, a giant like Samsung, which has already invested significant resources in installing microUSB in helmets virtual reality Gear VR, it didn’t make sense to change your decision in favor of a new generation port, losing a fabulous investment.

How can I be sure I'm buying a safe cable?

First of all, you need to give preference to cables from the manufacturer of your gadget, if one is not included with it. These cables are designed to work specifically with your device, avoiding any risks. Although mistakes are possible here too. For example, Apple company in February of this year recalled the cable for USB port-C some devices. Unlike many other manufacturers, the company admitted its mistake and allowed customers to replace the faulty components.

If you do not want to buy a cable from the manufacturer of your device, make sure that another supplier will provide a quality product.

Or maybe USB-C is just a fad?

In contrast to this, I would like to say that the port is a standard that has already been adopted by Apple, Google, LG, HTC, as well as dozens of other companies in the world. This means that all electronic device users will switch to USB-C.

It would seem that the USB Type-C standard has just begun to earn its reputation in the world mobile technologies, but 2015 has already given us a certain number of devices that have been 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 continue to grow this year. The largest manufacturers will continue to fight fiercely for consumers, supplying Type-C connectors not only to their flagship models, but also to offerings in lower price segments.

If you regularly use external batteries or other portable chargers designed for microUSB, this will add to your headache: in order to continue to benefit from your favorite accessories, be prepared 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 a USB Type-C connector, which, among other things, has a number of significant advantages over its competitors: recharging the device via a 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. 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 presented below are not in your local store, their cost allows you to order them from ebay, amazon or other online platform without hassle 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 charging the battery, a case and a microUSB cable.

Note that Anker PowerCore+ boasts several unique discoveries 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 cable resistance, thereby ensuring process stability. Unfortunately, the Anker PowerCore+ does not support Qualcomm Quick Charge 2.0 technology.


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

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


The price of a RAVPower power bank with a capacity of 20100 mAh is approximately $60. The discreet design - a black box with a four-point LED indicator - contrasts clearly with the excellent functionality: microUSB connector responsible for recharging RAVPower; another USB port is ready to cooperate with Qualcomm Quick Charge 2.0 and 3.0 technologies; speed is provided by the USB 3A Type-C interface.

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

It is noteworthy that the declared 20,100 mAh should be enough to revive the Galaxy S6 five times; To restore your iPhone 6S to full charge, you will have about 8 attempts. RAVPower is also able to protect your device from “overcharge” and preserve the health of its sensitive microcircuits.

Overall, RAVPower is an excellent choice for those who dream of a large portable battery with tons of additional features and support for Quick Charge 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 charges via microUSB 2.0 and has 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, with the exception of the handsome 12-inch Macbook. This wonderful battery also allows you to charge two smartphones simultaneously.

If you don’t have extra funds to buy an expensive “power bank”, Talentcell is ready to offer its services. The reviews for 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. This 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 Type-C interface. The lack of Qualcomm Quick Charge support here is compensated by the ability to “mega” fast charge 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 Still, it was worth considering - fast food is harmful.

At the beginning of its journey, the USB port was intended to combine all other interfaces into one, this was even hinted at by its constant logo, but as time goes on, the universal port itself has grown into many poorly compatible versions, which brought even more chaos into the relationship of certain gadgets. And finally, He appeared on the horizon. The great and terrible USB Type C. Knowledgeable people greeted it with almost applause, and ordinary users just shrugged their shoulders. You can still encounter this indifference today: they say, yes, it’s symmetrical, yes, it’s easier to connect, so what? In fact, the difference is huge, and if you are still wondering what is better - Type C or microUSB, this is the place for you.

Type C is more practical

This compact port has announced itself as a new network standard and its appearance is consistent with such a high status. A symmetrical, 24-pin port can today be found on smartphones in the flagship and mid-price segments, laptops, docking stations, routers and a huge number of other equipment. It does not take up much space on the case and, yes, it is more convenient to connect. And now you don’t have to carry around a certain number of blocks from different equipment with you.
Backward compatibility is also important. The Type-C port allows you to use any technology from the most ancient to the ultra-modern without any special restrictions.
A couple of years ago, there was an urgent issue of finding adapters and compatible flash drives, but today they are a dime a dozen on the market.

Data transfer speed - up to 10 Gb/s

In this regard, Type C is a great foundation for the future, because it offers users data transfer speeds of up to 10 Gb/s. Modern smartphones This, of course, is not necessary, but in the future it may well come in handy.
Here, by the way, we must immediately put an end to the confusion. The first Type C installed on a smartphone (by the way, it was Nokia N1) supported only the 2.0 protocol, while later devices could have both 3.0 and 3.1 with corresponding data transfer rates. This limitation is imposed by the manufacturer with an eye to modern realities and will invariably increase.


Charging - up to 100 W power

Fast charging is already sweeping the planet. They are being developed different manufacturers and they work on different principles, but the essence is the same - to increase power and thus reduce the charging time of the gadget. If you read our previous text, you noticed that in modern technologies fast chargers The numbers don't even come close to what's listed. However, in the future, this seemingly sky-high power will also be used. This technology You may have come across it on the Internet under the name USB Power Delivery. This is what many see as the future standard for fast charging.
Moreover, the Type C port can not only charge, but also charge other devices, which third-party manufacturers will obviously not fail to use in their developments.

Alternate Modes

If up to this point we were talking exclusively about proprietary developments, now it’s time to look at related technologies. Type C will also allow you to connect to monitors with DisplayPort, MHL and HDMI.
You can’t ignore Thunderbolt 3, which guarantees data and video transfer to high speeds. Through of this interface you can daisy chain up to 6 peripheral devices(for example, monitors). It's really hard to imagine a situation where this is really necessary.

Sound transmission - audiophile quality

If we assessed all the above modes in the context of a reserve for the future, then this is something that even ordinary users are faced with today. We are talking about a massive replacement of the audio jack with a Type C port. Separated ports, in this case, have only one (but very serious) advantage: you can use headphones even when the smartphone is charging. But in all other respects, the analog jack is inferior to the digital USB-C. In the latter case, the sound quality will be higher, noise reduction and echo cancellation will be better implemented. Equally significant is the ability to transfer some tasks (and related equipment) to the headset, which will also help avoid unnecessary noise and expand the headset’s control capabilities. The other side of the coin is that headphones will clearly become more expensive than modern simple “whistles” or, in other words, “whistles” will simply die out as a species.
And in the future, according to the developers, cooler things await us. For example, the ability to monitor body temperature while playing sports using headphones.

Docking stations

It is the versatility of the USB Type C port that made the use of docking stations for smartphones possible. Connecting to a dock makes it possible to turn your smartphone into an almost full-fledged desktop PC. Not at the gaming level, of course, but definitely at the multimedia level, thanks to the power mobile processors this is more than enough. There are currently two devices on the market that offer this functionality. This HP Elite x3 which we did big on review and models Samsung Galaxy S8 , S8+ And Note8 with their DeX Station. Considering the speed with which Type C is spreading, I would like to hope that other manufacturers will have analogues.

As we see, a miniature Type-C port is not only charging, as many people think, but also a sea of ​​other possibilities. It is for the versatility of USB-C that they value it. But the sea of ​​these undeniable advantages crosses out one fat minus. The capabilities of the port will always be limited by the carrier device and it is impossible to recognize these limitations externally. That is, Type C always looks the same, and to find out what exactly it will be able to do on a particular device, you will have to look for detailed specifications. Moreover, the difficulties here will be not only with the presence/absence of alternative modes, but also with the speeds involved. Moreover, the compatibility of two devices can be “killed” by using the wrong cable. This is a pretty good game of attentiveness. The only good thing is that these restrictions will gradually be leveled out with the development of technology.
