USB connectors: types, their description, advantages and disadvantages. USB Type-C: everything you wanted to know Usb type c pinout

We are on the verge of significant changes - to replace the classic and familiar USB 2.0 and 3.0 ports, a new, backwards compatible type of connector is coming. Despite external convenience, symmetry and visual simplicity, list USB capabilities Type-C is not only impressive, but also fraught with many non-obvious difficulties for the user.

The first USB standard appeared in 1994 to solve the key problems of that time: the unification of the connector for the peripherals of PC equipment combined with high data transfer rates. Since 2001, the version of the USB 2.0 connector (as well as its various variations) has become a universal connection standard for any peripherals. The key to fifteen years of USB success is simplicity, because there are only four pins inside that provide power and communication to the connected device.

What was an advantage in the 2000s has become a bottleneck for modern devices - USB ports can no longer cope with an almost exponentially growing amount of information, users have appreciated the advantages of symmetrical (and fast!) Mobile reversible connectors (such as Apple Lightning), cables in which you can insert both sides, and the speed wireless transmission data is very close to the speed of a cable connection.

USB 3.0 only highlighted the problem by mechanically increasing the number of additional pins to five, which increased the maximum throughput from 480 Mbps to 5 Gbps, and the maximum current increased from 500 mA to 900 mA. The new connector also received its distinctive marking - a blue socket. USB connectors 3.0 requires 9 pins to work.

Let's see how much the USB Type-C / USB-C / USB C connector differs from its predecessors, what are the prospects and difficulties of switching to a new type of connector, and what types of cables it can replace with itself in the near future.

The confusion starts with the name: “USB Type-C”, “USB-C” and “USB C” are different names for the same connector that can work with different protocols. Until a common name settles, we'll stick with the USB Type-C name - though The general trend indicates the growing popularity of the shorter USB-C variant.

The diagram of backward compatible USB Type-C protocols allows you to understand what functions the new connector can take on - there were unexpectedly many of them, which is good news. The most important thing about this diagram is that each next level is backwards compatible with the levels below.

The fastest protocol for the new connector is Thunderbolt 3. The Thunderbolt hardware interface was developed by Intel in collaboration with Apple. The Thunderbolt trademark itself was formerly owned by Apple, but was later transferred to by Intel. USB Type-C connectors that work with this protocol are installed in new

But the USB Type-C port in the previous one is a “step below”, allowing you to connect peripherals compatible only with the USB 3.1 gen 1 standard, but not with Thunderbolt 3.

This good example, which clearly demonstrates in practice why, despite the same USB Type-C connector, Thunderbolt 3 peripherals cannot be connected to Macbook 12, however, any accessories and peripherals for Macbook 12 will work with the new Macbook Pro 2016.

Let's take a closer look at what other types of signals USB Type-C can transmit through itself.

First of all, these are classic USB 2.0 and USB 3.0 - this is true for mobile devices with a new connector (such as the first tablet with USB Type-C Nokia N1), which supported signals and power only for USB 2.0. Most modern mobile devices (for example l) support USB connection 3.0.

What does this mean in practice? When purchasing a cable for a USB Type-C mobile device, pay attention to the speed and connector compatibility of both gadgets. good choice for a modern Windows laptop with USB 3.0, there will be a cable that will provide operation via USB Type-C using USB 2.0 and 3.0 protocols.

If your mobile device, such as an Android smartphone, is equipped with a Micro-USB port (or its Micro-USB B modification) that operates using the USB 2.0 protocol, you can limit yourself to a cable, or. The maximum data transfer rate will be limited to 480 Mbps.

The next standard is USB 3.1 gen 1 - allowing you to connect hard disks, network adapters and docking stations. It is backward compatible with "SuperSpeed" USB 3.0, "Hi-Speed" USB 2.0 and even original USB 1.x protocols.

USB 3.1 gen 2 protocol - similar to the previous one, but doubles throughput USB peripherals up to 10 Gbps. Only the newest USB-C devices support it.



USB 3.1 and USB Type-C connectivity support and external drives, For example .

Examples of accessories providing compatible speed network connection via USB Type-C:
And .

Audio Accessory Mode is a specification for use with analog audio, allowing the USB Type-C port to compete in the future with the analog 3.5mm jack.

Connection mode Alternate Mode (alternative mode) - includes all other non-USB protocols: these are DisplayPort, MHL, HDMI and Thunderbolt (which was previously connected via the DP connector). The main problem here is that not every device supports the Alternate Mode protocol, which is very confusing for buyers.

For video devices, not only Apple's proprietary USB Type-C adapters are available: and an adapter, but also options from other manufacturers, for example.

But there are also advantages - the transfer of a video stream via the USB Type-C port does not affect its energy capacity in any way, because as many as four high-speed lines can be allocated to the needs of DisplayPort. In this case, it is possible to transmit images in resolutions up to 5120×2880.

The symmetry of the contact pads made it possible to make the port reversible, and depending on the connected device, a different number of connections are involved.

The first USB 1.0 port provided only 0.75W (0.15A, 5V) of power. For USB 2.0, the current strength was increased to 0.5 A, which made it possible to get 2.5 watts from it to power, for example, external hard drives 2.5" format. Not surprisingly, connecting more power-intensive drives sometimes required several ports at once.

For USB 3.0, a current of 0.9 A is provided, which, with a supply voltage of 5 V, guarantees a power of 4.5 watts. Against the background of these numbers, the ability to transmit 100 watts is really impressive!

To ensure the transfer of this amount of energy, the supply voltage can be increased up to 20 volts. Contacts Secondary Bus and USB Power Delivery Communication are designed to select the desired mode of operation between the connected gadgets - because if the device is not capable of receiving 100W of energy, it will simply burn out! Pre-sharing puts compatible devices into advanced mode with more power options.

There are five such profiles in total: “profile 1” guarantees the possibility of transmitting 10 W of energy, the second - 18 W, the third - 36 W, the fourth - 60 W, and the fifth - a whole hundred!

The PD (Power Delivery) function requires a separate cable, such as

The outlook for USB Type-C or USB-C is very bright. Except for Apple USB ports Type-C is beginning to be equipped with both productive desktops (motherboards) and mobile devices. So far, the USB 3.1 protocol in both of its variations has taken the lead (and mobile devices are just getting close to USB 3.0 speeds).

It won't be long before we can finally switch to a universal type of USB-C to USB-C cables (such cables are available now) to connect the rest of the peripherals. It is especially pleasant that the accessories purchased today will continue to work thanks to the mode backward compatibility. Important note- USB Type-C is an open standard that requires no royalty from manufacturers.

Risks and difficulties are only when connecting new peripherals (requiring the fastest protocols, such as Thunderbolt various versions) to older USB Type-C devices running at USB 3.1 speeds - in the best case, they will be able to continue working at a reduced speed.

When buying accessories and USB Type-C cables, be sure to consider at what speeds your device should (and can) work - if USB 2.0-3.1 speeds are suitable for mobile devices and gadgets, then for transferring video or data from hard drives high capacity Thunderbolt 3 compatibility may be important.

For your convenience, we have collected in a separate section of the catalog.

Advantages of the USB 3.1 port:
★ fast
★ powerful
★ universal

Advantages of the Type-C connector:
★ durable
★ symmetrical

Now it is guaranteed that you can connect the USB cable to the device the first time.

⚠ It is necessary to distinguish between the concepts " port" And " connector». Connector(socket) Type-C can be soldered even to an old phone (instead of micro-USB), but port so it will remain old usb 2.0 - it will not increase the speed of charge and data transfer. Of the amenities, only the symmetry and reliability of the connector will appear.

⚠ Thus, the presence of Type-C does not mean anything yet. Smartphone models with a new connector are on sale, but with old port. The advantages listed in this article do not apply to such smartphones.

Pin assignment

Connector contacts in the diagrams are shown from the outer (working) side, unless otherwise specified.

The port contains 24 pins (12 pins on each side). The "upper" ruler is numbered A1 ... A12, the "lower" - B1 ... B12. For the most part, the rulers are identical to each other, which makes this port indifferent to the orientation of the plug. The contacts of each line can be divided into 6 groups: USB 2.0, USB 3.1, Power, Ground, Matching channel And Additional channel. Now let's take a closer look.

Actually, USB 3.1. High speed data lines: TX+, TX-, RX+, RX- ( pins 2, 3, 10, 11). Speed ​​up to 10 Gb/s. In the cable, these pairs are crossed, and what is RX for one device is presented as TX to another. And vice versa. By special order, these pairs can be retrained for other tasks, for example, for video transmission.

Good old . Low speed data lines: D+/D- ( pins 6, 7). This rarity was included in the port for the sake of compatibility with old low-speed devices up to 480 Mb / s.

Power Plus - Vbus(pins 4, 9). The standard voltage is 5 volts. The current is set depending on the needs of the periphery: 0.5A; 0.9A; 1.5A; 3A. In general, the specification of the port implies a transmitted power of up to 100W, and in case of war, the port is able to power a monitor or charge a laptop with 20 volts!

GND - Mother Earth (pins 1, 12). Minus everything and everyone.

Matching channel(or configuring) - SS ( pin 5). This is the main feature of USB type-C! Through this channel, the system can determine:

- The fact of connecting / disconnecting a peripheral device;
— Orientation of the connected plug. Oddly enough, but the connector is not absolutely symmetrical, and in some cases the device wants to know its orientation;
- Current and voltage that should be provided to the periphery for power or charge;
- The need to work in an alternative mode, for example, to transmit an audio-video stream.
- In addition to monitoring functions, this channel, if necessary, supplies power to the active cable.

Additional channel - SBU (pin 8). The additional channel is not normally used and is only provided for some exotic cases. For example, when transmitting video over a cable, an audio channel goes through SBU.

USB 3.1 Type-C pinout

The "striped color" here shows the contacts of an uninsulated wire.

A strange decision was to mark the D+ and D- wires not as in USB 2.0, but vice versa: D+ is white, D- is green.

Wires are marked with a gray stroke, whose color, according to Wikipedia, is not regulated by the standard. The author did not find any indication of the colors of the wires in official documentation.

Power/Charge Technology USB PD Rev.2 (USB Power Delivery)

The USB-C cable does not have such concepts as "connector-A" or "connector-B" - the connectors are now the same in all cases.

Device roles are denoted by new terms:

DFP- an active power supply device (like a USB port) A)
UFP- passive, receiving device (like a USB port) B)
DRP- "two-faced", dynamically changing its status device.
In addition, the charger is called power provider, rechargeable - power consumer.

The distribution of roles is carried out by setting a certain potential on the CC contact using one or another resistor:

Active device ( DFP V bus.
The value of the resistor tells the consumer what current he can count on:
56 ±20% kΩ - 500 or 900 mA
22 ±5% kΩ - 1.5 A
10 ±5% kΩ - 3 A

Adapters from USB 2.0 (3.0) to USB-C, which are used to connect new smartphones to old PCs or storage devices, are soldered according to the DFP scheme, that is, they show themselves to the smartphone as active device

passive device ( UFP) is determined by the resistor between the contacts CC and GND.
Resistor rating: 5,1 kOhm

Adapters from USB-C to USB-OTG are soldered exactly according to the UFP scheme, that is, they imitate a consuming device.

⚠ USB PD Rev2 technology in which by contact CC agree current And voltage charge should not be confused with Quick Charge (QC) technology, where the contacts D− And D+ only agrees voltage charge. USB PD Rev2 is only supported in USB 3.1.
QC is supported without reference to the port version.

Analog audio via Type-C

The standard provides for the possibility of transmitting analog audio through a digital port. This feature has been implemented in HTC smartphones U series, HTC 10 Evo, Xiaomi Mi, LeTV. The author will be grateful if the reader adds to this list.

To work in this mode, analog headsets with a Type-C plug are used. Adapters are provided for connecting the classic.

Analog audio is transmitted on the Data−, Data+, SBU1 and SBU2 channels. The smartphone enters this mode if the headset plug or adapter between contacts A1-A5 and B1-B5 resistance less than0.8…1.2 kOhm. Instead of a resistor, I could see just a jumper.

Video via USB-C

To transfer video via USB 3.1, the "DisplayPort Alternate Mode" has been developed.
See the list of devices that support this mode. I think it will be very useful to many. I don’t know what kind of cord you had and did it work with QC3.0 before? How many lived in it? "Normal USB" - what is it?

In my materials devoted to the choice of - thin ultra- and other beeches, I no-no, and I mentioned USB interface Type-C, the presence of which is an undoubted advantage of a particular computer model. Let it be a small advantage, incomparable in importance with a video card, etc., but we know who lies in the details, and it is these small pluses and minuses that can tilt the bowl of choice in one direction or another, influencing the decision which model to prefer and which laptop to buy. So, USB Type-C - what is it, what is it eaten with, in the sense of how and for what it can be used and whether it is needed at all. Understanding?

USB Type-C - what's in my name for you?

I will not repeat the history of the appearance and development of the USB interface. It has become so familiar that even the decision once made by someone to make the connector asymmetrical still infuriates, but not much anymore. The point is that you need to insert a USB flash drive or cable into a familiar USB socket in a certain position. How often did you manage to connect the device to the connector on the back side the first time system block the first time? And from the second? Well, maximum from the third.

True, it should be noted that the connector is reliable, withstands a large number of connections, is able to resist well (within reasonable limits, of course) mechanical loads. But a disadvantage follows from these qualities - for compact devices in its original form (Type-A), it is too bulky.

Which exit? To do the same, but less, as a result, Mini-USB, Micro-USB appeared. Got better? Yes, but still somehow uncomfortable, for different devices you need different cables or adapters, and you still need to insert even small connectors in a certain way.

So, Type-C is new standard connector, which finally (bonnets up and champagne corks in the ceiling) has become symmetrical! Its compactness and versatility allows you to replace the entire existing "zoo" of connector options and, accordingly, cables. At the same time, it was developed under the new specification of the USB standard, which received the number 3.1.

The main characteristics of standards 3.0 and 3.1 are given in the table.

VersionUSB 3.0
Max. transfer rate, Gb/s5 5 10
Max. current, A0.9 5
Coding8b/10b128b/132b
Cable length, m2-3 1
Resource (number of connections)1500 (Type-A)10000

We add that through Type-C it is possible (considering a current of 5 A) to charge the device itself, connect an external monitor, peripheral devices, drives ... It turns out that if a laptop has such a connector, then it will be possible to take advantage of all these benefits?

- And then let the water down, and there may be ...

- What can be there?

- Anything, you understand?

Not certainly in that way. You are guaranteed to get a new compact connector and USB in it. I deliberately do not indicate which version of the protocol can be there, because Type-C is a specification of the connector and what MAY be in it, but what is used in specific model tablet or laptop - it already depends on the manufacturer of this gadget.

Type-C - features

As it has already become, I hope it is clear, the new connector is already more than just USB, and much more. In, if I may say so, "basic" configuration, it provides USB operation 3.1 with all the benefits of this new version interface.

All other "buns" are alternative Type-C modes of operation, which are marked in a certain way on the device case. Moreover, changes can lead both to the expansion of the used capabilities, and to the fact that USB 3.1 can be replaced by 3.0 or even 2.0. Here are the options that can be found on this moment, because the possibilities of this connector are far from being exhausted.

displayport. Through Type-C, you can connect an external display with a maximum resolution of 3840 x 2400 pixels. Such an opportunity should be marked either on the laptop case with an appropriate icon, or indicated in the specification for the device.
HDMI. Now you can connect external devices without adapters, directly using HDMI version 1.4.
Thunderbolt. Support for Thunderbolt 3 protocol compatibility mode.
Power Delivery (PD). Specification of a new standard that provides the transfer of currents up to 100 W in both directions, which allows you to charge a laptop through this port, or, conversely, power the connected through it external device such as an external display. On the body of the device, such a connector is usually marked with the letters PD, with an icon in the form of a battery, although there may be other options. If there is no PD support, then the maximum output current will be 1.5 or 3 A, depending on the modification.
Support for USB 3.1 Gen.1 protocol. Support for speeds up to 5 Gb / s.
Support for USB 3.1 Gen.2 protocol. Support for speeds up to 10 Gb / s.

What functions are supported by Type-C installed in a particular laptop model is marked on the case, or written in the specifications.

For example, consider the Lenovo Yoga 910 convertible laptop. It is equipped with two Type-C ports, one of which works on USB 2.0 (by the way, here is an example of the fact that no one promised USB 3.1 is mandatory), and the second is 3.0 with DisplayPort support . Moreover, the function of supporting the charging mode through this connector is simply marked with an electric plug icon, without frills like the “PD” logo, etc. The same applies to support for connecting a monitor. This is clear only from the documentation for the laptop.

Another example is the Asus ZenBook 3 UX390UA ultrabook, which, apart from the audio jack, has only one Type-C. But it can do almost everything: a power supply is connected to it, through it you can display an image on an external display, exchange data with external media at speeds corresponding to the USB 3.1 Gen.1 interface. By the way, pay attention to the marking of the connector on the case. Everything is clear, clear and understandable.

prospects

The specification for the following is currently under active development. USB versions– 3.2, while Type-C will be used, the possibility of working with the PCI Express and Base-T Ethernet protocols is being worked out. In general, this connector is the future, though not so actively promoted so far. The reason is a huge number of devices for old connectors, to connect them you will have to buy adapters and hubs.

Conclusion. USB Type-C - what is it, the future ruler of gadgets?

Quite possible. The presence of a single, universal connector is rather a blessing. The ability to use one connector to connect both power, and a USB flash drive, and all sorts of other devices is tempting. There is only one "but".

If power is connected through the port, or other devices are powered with it, and at high powers, then you should pay special attention to the quality of the wires, adapters and hubs used. Poor quality Uncle Liao products can lead to unpleasant consequences in the form of burnt devices with subsequent costly repairs.

High speeds to you, dear readers, and safe connection!

Everything is on sale lately. more phones and smartphones that use a new connector called USB Type-C instead of the traditional Micro USB. This type connector appeared not so long ago and so far they understand what it is and how it works.

If you also have questions related to USB Type-C, then we suggest that you read this article. Here you will learn what USB Type-C is, how it differs from Micro USB, and which is better to choose. If you are also interested

What is USB Type-C in phones and smartphones

USB interface logo.

In order to understand what USB Type-C is, you need to make a short digression into the history of this interface. is a computer interface that appeared in the mid-1990s and has since been actively used to connect peripheral devices to a computer. With the advent of smartphones given interface began to be used in them, a little later, USB began to be used in ordinary mobile phones with buttons.

Initially, the USB standard included only two types of connectors: Type-A and Type-B. The Type-A connector was used to connect to a device on the side of which a hub or USB interface controller was used. The Type-A connector, on the contrary, was used on the side of the peripheral device. Thus, a conventional USB cable included two Type-A connectors, which connected to a computer or other control device, and Type-B, which connected to a peripheral device.

In addition, both Type-A and Type-B have smaller versions of connectors, which are designated as Mini and Micro. The result is a fairly large list of different connectors: USB Type A, Mini Type-A, Micro Type-A, regular Type-B, Mini Type-B and Micro USB Type-B, which is commonly used in phones and smartphones and is better known as Micro USB.

Comparison of different connectors.

With the release of the third version of the USB standard, several more additional connectors that supported USB 3.0 are: USB 3.0 Type-B, USB 3.0 Type-B Mini and USB 3.0 Type-B Micro.

This whole zoo of connectors no longer corresponded to modern realities, in which easy-to-use connectors, such as those from Apple, were gaining popularity. Therefore, along with the USB 3.1 standard, a new type of connector called USB Type-C (USB-C) was introduced.

The advent of USB Type-C solved several problems at once. First, USB Type-C was originally compact, so there is no need to use the Mini and Micro versions of the connector. Secondly, USB Type-C can be connected to both peripherals as well as computers. This eliminates the scheme in which Type-A was connected to a computer, and Type-B to a peripheral device.

In addition, USB Type-C supports a lot of other innovations and useful features:

  • The data transfer rate is from 5 to 10 Gb / s, and with the introduction of USB 3.2, this speed can increase to 20 Gb / s.
  • Backward compatible with previous USB standards. Using a special adapter, a device with a USB Type-C connector can be connected to a regular USB of previous versions.
  • Symmetric connector design that allows you to connect the cable in either direction (same as Apple's Lightning).
  • The USB Type-C cable can be used for fast charging mobile phones, smartphones, and compact laptops.
  • Support alternative regimes works in which USB cable Type-C can be used to transfer information over other protocols (DisplayPort, MHL, Thunderbolt, HDMI, VirtualLink).

What is the difference between USB Type-C and Micro USB

USB Type-C (top) and Micro USB cables.

Users who choose mobile phone or a smartphone, are often interested in the difference between USB Type-C and Micro USB. Below we have compiled the main differences and advantages of these connectors.

  • USB Type-C is the connector for the future. If you choose a flagship smartphone that you plan to use for several years, then you should pay attention to models with USB Type-C. This connector is actively gaining popularity and in the future more and more devices with its support will appear. Do not be afraid of problems with connecting to a computer. If your computer is not equipped with this connector, then you can always connect your phone using an adapter.
  • USB Type-C is convenient. Thanks to the symmetrical design, connecting USB Type-C is much easier than classic Micro USB. In order to put a phone with USB Type-C on charge, you just need to plug the cable into it, and you don’t need to look at the connector and choose which side to connect it to. In addition, due to their symmetry, USB Type-C connectors are more stable and rarely damaged.
  • USB Type-C is fast. As we have already said, USB Type-C supports data transfer rates from 5 to 10 Gb / s. If the phone supports this speed, then you can copy data much faster than using Micro USB, which is limited by the USB 2.0 standard (up to 480 Mbps).
  • Micro USB (or rather Micro USB Type-B) is a time-tested connector, the main advantage of which is its prevalence. Charging and a cable with such a connector can be found in any office or home. Therefore, with Micro USB, you will always find where to charge your phone or smartphone.

Which is better USB Type-C or Micro USB

We conclude the article with an answer to the question of which is better, USB Type-C or Micro USB. In short, USB Type-C is definitely better. A phone with USB Type-C can only be bought for the sake of a symmetrical connector. Most users charge their phone daily, so such a trifle as a symmetrical connector that can be connected to either side makes life much easier. On the other hand, if you often charge your smartphone outside the home, then the usual Micro USB may be preferable. So you will have less trouble finding the right cable or adapter.

Also note the data transfer rate. If your phone and computer support USB 3.1, then via USB Type-C can transfer data at speeds up to 10 Gbps, while Micro USB can provide a maximum of 0.5 Gbps.

It would seem that the USB Type-C standard has just begun to earn its reputation in the world mobile technology, but 2015 has already managed to give us a certain number of devices that have tried on new interface: The 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 charging device, sharpened for microUSB - 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 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 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 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 declared 20100 mAh should be enough to return to Galaxy life S6; 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.

In general, RAVPower will become excellent choice for those who dream of a capacious portable battery with a bunch of additional features 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 carry out simultaneous charging 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 is better to take TalentCell and eat, but additional option Still, it was worth considering - after all, fast food is a harmful thing.
