Cheap smartphones with usb type c. Why do you need USB Type-C and which devices already have it? What is the OTG standard
The best smartphones with USB Type-C. Selecting ZOOM
For most users, a plus from the emergence of USB There is only one Type-C in smartphones: the charging cable does not need to be held to your eyes to see which side to insert into the device connector. In the dark, this procedure is even more inconvenient - you need to poke the metal connector at random. As a result - small scratches around the charging socket.
USB Type-C solves the problem: you don’t have to unwrap the cable, the main thing is to get there. The second advantage compared to a typical microUSB is stability: as a rule, Type-C stays in the socket more tightly than cables of previous generations.
But then things get even more interesting. First you need to separate USB Type-C from USB 3.1: the first is a regular connector, and the second is a standard, but they follow a parallel course. Nominally, USB 3.1 supports a speed of 10 Gbps and a voltage of 20V (100W). Hence the conclusion: soon using miniature USB Type-C cable It will be possible to charge laptops (power up to 60W): away with huge cables with power supplies.
This solution has already been implemented in 12-inch Apple MacBook. There, the Type-C connector is the only one: Apple wanted to demonstrate the versatility of this technology, so it abandoned the remaining sockets. USB Type-C is really enough to connect monitors, peripherals, charge other gadgets and power the device itself. It is worth admitting: “on paper” Type-C is close to becoming a single connector for all technical devices. By at least, there is enough power.
However, everything is not so simple: there is a version that, according to some parameters modern gadgets They themselves have not yet matured to USB Type-C and USB 3.1. For example, mobile processor Snapdragon 820 (the most current for the first half of 2016) only supports USB 3.0 (up to 500 MB per second), but not 3.1. Sometimes entire companies abandon Type-C. Samsung Galaxy S7 could have received this connector, but did not receive it for three reasons. Firstly, the leaders of the Korean corporation believed that the market was not ready for such changes - everyone was accustomed to microUSB. Secondly, Samsung already has fast charging. Thirdly, the helmet virtual reality The Gear VR has a microUSB connector. According to rumors, Type-C will appear in Galaxy Note 7, which will be announced in a month.
Apple is also in no hurry to abandon lightning in favor of Type-C, but at the end of 2015 information leaked that an iPhone with touch key Home and another connector. Accordingly, in theory, the Americans are ready to submit general trend, but in 2016 there will definitely not be a mass transition to Type-C. Most likely, the revolution has been postponed until 2017.

Nevertheless, there are already enough devices on the market that support the new connector. True, their main advantage is still the same - the ability to insert the cable from either side.
LG G5 SE
Korean modular flagship(see) has been officially on sale in Russia for 50 thousand rubles for several weeks now. On the plus side - big screen(5.3 inches, QHD), latest Android (6.0), Always-On-Display function and ultra-fast charging with a proprietary adapter: 83 percent in half an hour.
The downside is that it's a compromise (the standard G5 has 4 GB random access memory and more powerful processor) and the price of the modules: 10 thousand for a Hi-Fi player, 3 thousand for external battery and 5 thousand for the shutter button for the camera.
HTC 10 LifeStyle
As in the case of LG, HTC also did not dare to send a truly flagship model to Russia. differs from the usual “ten” by three (instead of four) gigabytes of RAM and Snapdragon processor 652, but otherwise everything is at the top level: a nice metal body, an excellent 5.2-inch QHD screen, a 12-megapixel main camera, a fingerprint scanner and a 3000 mAh battery (full charge in 60-70 minutes).
The price of the device is 45 thousand rubles, and one of the important features is splash protection: you can’t drown the phone, but you also don’t have to worry about drops getting on the case.
Huawei Nexus 6P
The metal Google phone was announced back in 2015, so it is the most profitable to purchase: it costs less than 40 thousand rubles even in the top-end 64-gigabyte modification. Besides USB port Type-C, there is a 5.7-inch QHD screen, a Qualcomm Snapdragon 810 processor, a luxurious 12-megapixel camera, an 8-megapixel front-camera and a 3450 mAh battery (full charge in an hour and a half).
In terms of "price - quality" - one of best offers On the market. For example, an iPhone 6s Plus with the same amount of memory costs almost twice as much.
LG Nexus 5X
The Nexus 6P's little brother is the most affordable yet popular smartphones with USB Type-C. For 18-30 thousand rubles (depending on the retailer) you will get a device with a 5.2-inch FullHD screen, a fingerprint scanner, a six-core Qualcomm Snapdragon 808 and always up-to-date Android.
Time fully charged batteries with a capacity of 2700 mAh - an hour and a half.
Microsoft Lumia 950XL
Devices on Windows Phone(Windows Mobile) may be criticized for its lack of applications, but last fall Microsoft introduced one of the most interesting solutions for smartphones: $99 hub turns flagship Lumia (950/950 XL) into full-fledged computers- you just need to connect the screen, keyboard and mouse. Other manufacturers, of course, do not have this function.
In addition to USB Type-C and the ability to transform into a PC, the Lumia 950XL boasts a 5.7-inch QHD screen, a 20-megapixel camera and a 3450 mAh battery that charges up to 50% capacity in half an hour. The current price of the device is 40 thousand rubles, and it will become more difficult to find every day.

Why new standard USB is really better than the usual USB ports on phones, tablets or laptops, and which devices already have USB Type-C connectors? The CHIP editors answer all these questions.
First a little important information: The designations USB Type-C and USB 3.1, as they say, go hand in hand, since they actually mean the same thing. When the USB 3.1 number is used, it is usually referring to the data transfer speed.
If you come across the name USB Type-C, it usually refers directly to the type of connector for connecting devices. First, let's compare the previous USB 3.0 standard with new USB 3.1. You will find all the details in the table below.
Comparison of USB 3.0 and USB 3.1
The best devices with USB Type-C
What devices with a USB Type-C connector are generally available in currently? The first of these was the 12-inch MacBook, in which this connector was the only one. The current Google phones Nexus 6P and 5X are also equipped with USB 3.1 - and in general, more and more manufacturers are integrating a port of the new standard into their smartphones.
In the following table we have compiled for you a list of the most interesting devices with USB interface Type-C.
USB Type-C: these devices already have it
The USB connector can no longer be connected incorrectly
USB Type-C: Type C plug (left) can be used on either sideThat's what makes the USB Type-C connector incredibly convenient: it's symmetrical. You no longer have to think about how hard it will take to insert the plug into the socket correctly. Previously, this connector property was a big advantage of the product. Apple, iPad or iPhone, and now it is becoming available to the masses of users. This cable can be inserted in either direction.
Let us mention one more significant advantage over the USB 3.0 standard: due to the maximum transmitted power increased to 100 W, USB 3.1 will not be used in the future additional source power supply will be able to connect various peripheral devices, such as monitors or speakers. The current strength of 5 A also significantly reduces the charging time of a mobile phone.
Most modern mobile phones, smartphones, tablets and other wearable gadgets, supports charging via the USB mini-USB or micro-USB socket. True, a single standard is still far away and each company is trying to do the pinout in its own way. Probably they should buy the charger from her. It’s good that the USB plug and socket itself were made standard, as well as the supply voltage of 5 volts. So, having any charger adapter, you can theoretically charge any smartphone. How? and read on.
Pinout of USB connectors for Nokia, Philips, LG, Samsung, HTC
Brands Nokia, Philips, LG, Samsung, HTC and many other phones will recognize the charger only if the Data+ and Data- pins (2nd and 3rd) are shorted. You can short them in the USB_AF socket of the charger and easily charge your phone via a standard data cable.
Pinout of USB connectors on the plug
If the charger already has an output cord (instead of an output jack), and you need to solder a mini-USB or micro-USB plug to it, then you do not need to connect pins 2 and 3 in the mini/micro USB itself. In this case, you solder the plus to 1 contact, and the minus to the 5th (last).
Pinout of USB connectors for iPhone
For iPhones, the Data+ (2) and Data- (3) contacts should be connected to the GND (4) contact through 50 kOhm resistors, and to the +5V contact through 75 kOhm resistors.
Samsung Galaxy charging connector pinout
To charge the Samsung Galaxy, a 200 kOhm resistor must be installed in the USB micro-BM plug between pins 4 and 5 and a jumper between pins 2 and 3.
Pinout of USB connectors for Garmin navigator
For power or charge Garmin navigator A special data cable is required. Just to power the navigator via cable, you need to short-circuit pins 4 and 5 of the mini-USB plug. To recharge, you need to connect pins 4 and 5 through an 18 kOhm resistor.
Pinout diagrams for charging tablets
Almost anyone tablet computer charging requires a large current - 2 times more than a smartphone, and charging through the mini/micro-USB socket in many tablets is simply not provided by the manufacturer. After all, even USB 3.0 will not provide more than 0.9 amperes. Therefore, a separate nest (often round type) is placed. But it can also be adapted to a powerful USB power source if you solder an adapter like this.
Pinout of the charging socket of the Samsung Galaxy Tab tablet
For the correct charge Samsung tablet Galaxy Tab recommend another circuit: two resistors: 33 kOhm between +5 and jumper D-D+; 10 kOhm between GND and jumper D-D+.
Pinout of charging port connectors
Here are several diagrams of the voltages on the USB contacts, indicating the values of the resistors that allow these voltages to be obtained. Where a resistance of 200 Ohms is indicated, you need to install a jumper whose resistance should not exceed this value.
Charger port classification
- SDP(Standard Downstream Ports) – data exchange and charging, allows current up to 0.5 A.
- CDP(Charging Downstream Ports) – data exchange and charging, allows current up to 1.5 A; hardware identification of the port type (enumeration) is performed before the gadget connects the data lines (D- and D+) to its USB transceiver.
- DCP(Dedicated Charging Ports) - charging only, allows current up to 1.5 A.
- ACA(Accessory Charger Adapter) – PD-OTG operation is declared in Host mode (with connection to PD peripherals - USB-Hub, mouse, keyboard, HDD and with the ability additional food), for some devices – with the ability to charge PD during an OTG session.
How to remake a plug with your own hands
Now you have a pinout diagram for all popular smartphones and tablets, so if you have the skill to work with a soldering iron, there will be no problems converting any standard USB connector to the type your device needs. Any standard charge that is based on using USB, involves the use of only two wires - +5V and a common (negative) contact.
Just take any 220V/5V charging adapter and cut off the USB connector from it. The cut end is completely freed from the shield while the remaining four wires are stripped and tinned. Now take a cable with a USB connector the right type, after which we also cut off the excess from it and carry out the same procedure. Now all that remains is to simply solder the wires together according to the diagram, after which each connection is insulated separately. The resulting case is wrapped on top with electrical tape or tape. You can fill it with hot glue - also a normal option.
Bonus: all other connectors (sockets) for mobile phones and their pinouts are available in a single big table — .
The Type-C connector appeared after the new USB standard was developed. The USB 3.1 specification makes it possible to transfer data at incredible speeds of up to 10 Gbps, as well as power devices with up to 100 W of current. At first, not all equipment manufacturers appreciated the convenience of the new format: only Macbooks and Chromebook Pixels were equipped with a Type-C connector, but now it’s not difficult to find a gadget with such a connector.
Difficult to find inexpensive gadget with premium features. But we did it*. Five in front of you inexpensive smartphones with the latest Type-C connector.

Price - from 16190 rubles. Last year's event. Another brainchild of Google in company with LG. Excellent performance in almost all respects: the latest software at the time of release, high performance, high-quality case materials, robust build, great cameras, chipset and battery for LG Nexus. This model had only one drawback - a huge price tag. But a lot of time has passed since the official announcement, competitors are not asleep and the price has dropped quite well. You might want to think about purchasing. |
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 charging device 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 a smartphone with Android or Windows Phone looks like this:
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 the 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. Now mobile gadgets You won’t find one with a mini-connector on the market.
In addition to those USB connectors that 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 (in particular, 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 fast connection 2 USB devices with each other, without the mediation of a computer. Connect by OTG you can not only flash drive (although this, of course, is the most common case), but also, for example, 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 iPhone have also already appeared, but download it to an Apple device (without jailbreak) from external media Only photos and videos are obtained - 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 all modern gadgets can boast of having this standard, 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 on this new trend mobile electronics market! Manufacturers are actively mastering technology and equipping their flagship models 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 speed data transmission. 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 amount 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 – so that users can see the benefits for themselves Type-C and decide to abandon the standard connector. At the same time, Ravencraft admits that, perhaps, complete replacement USB-A will never happen.
