Types of USB connectors

Universal serial bus (Universal Serial Bus) or USB is an industry standard developed in the mid-1990s to standardize the connection of peripherals to a computer. He replaced most of the interfaces and is now the most common type of connectors for consumer devices.

Today almost every device, whether portable or stationary, has different types of USB connectors. But it is much more difficult than beginners think. Today we will discuss the types of USB ports and different standards.

Different types of USB

Many might now be brewing the question: “If the USB should be universal, that’s why he has a large number of types?”. The fact that these types of USB connectors have different functions. This helps to ensure compatibility in the event of a release device with improved characteristics. Let’s look at the most common types of USB ports.

  • Type-A – most cables have at one end a connector of this type is USB, there are cables and modern keyboards and mice. The same type of USB equipped personal computers and chargers;
  • Type-B is the port used to connect printers and other peripheral devices to the computer. But he is currently not distributed as distributed USB Type-A;

  • Mini USB – this was the standard connector for mobile devices before the advent of the Micro USB. This connector is less than the standard that can be understood by its name. This type of connectors is a bit outdated and was replaced by Micro USB, but this does not mean that these types of USB cannot be found anywhere;
  • Micro USB – at the moment is the standard for portable devices. It took all the major mobile manufacturers except Apple. But Micro USB is gradually beginning to replace the USB Type-C by the Way, there are different types of Micro USB connectors, but talk about that a little later.
  • Type-C – the cable may have at both ends the same connector. The claimed higher transmission speed and higher capacity compared to previous USB standards. This connector used by Apple to Thunderbolt 3. About USB Type-C will be discussed later;

  • Lightning – does not apply to the USB standard, but is a proprietary interface for mobile Apple products since September 2012. The device before that time I used a less compact 30-pin proprietary connector.

USB 3.0

The new standard provides a higher data transfer rate and is backward compatible with the old standard. In the form of USB 3.0 and USB 2.0 Type-A are the same, just new standard painted blue to distinguish USB 3.0 from 2.0.

But speed is only in the case where the connector, which is inserted into the cable or flash drive must be USB 3.0 and the cable or flash drive should have USB 3.0 connector.

Also, in addition to USB 3.0 Type-A there are other types of USB 3.0 connectors. Type-B and Micro version have additional contacts to provide a higher data transfer rate that destroys the compatibility of the connectors with the old versions, but old USB 2.0 devices can be connected to the new USB 3.0 connectors, but the speed boost you get.

Micro USB

If you have an Android device, you will need to have a Micro USB cable. Even the most ardent Apple fans can’t avoid this type of connectors in portable batteries, speakers and other.

Also there is division into types of connectors Micro USB. Mostly used Micro USB Type-B, Type-A not particularly common, and I do it in real life never seen. The same applies to Mini USB.

If you start to buy a lot of gadgets, you will soon begin to use different cables for different devices, still no difference. So you don’t have to buy extra wire if you do not lose or tear.

When buying cable, people usually buy the cheapest, which I do not recommend, as the quality of such products can be very bad. In the future this will lead to the failure of the cable.

Also decide the length of the cable. To travel the short cable is convenient, but at home so you can sit on the floor near the outlet. A long cable will get tangled up and otherwise disturb you. For portable battery I have a cable with a length of 35 inches, and the cable to charge the smartphone at home with a length of 1 meter.

USB On-The-Go

USB On-The-Go (USB OTG) is a relatively new standard that allows you to insert in portable devices flash drives intended for other USB interfaces, cables, to charge from the battery of your portable device and so on. USB OTG supports USB Type-A, but other types of USB ports.

Now imagine that you have an external hard drive, smartphone and laptop. What steps do you follow in order to move a file from an external hard drive to your smartphone? The easiest way is to first move the file from an external hard drive to the laptop and to a smartphone.

Now imagine that you have a USB OTG adapter. Just insert the adapter into your phone and the cable into it from an external hard drive. The need in the laptop disappears. Comfortable?

Unfortunately, not all devices support USB On-The-Go, so before buying the adapter I suggest you check your device to support USB OTG.

Adapter for Lightning exist, and they even iOS 9 all work, but to call it OTG as it is not particularly desirable.

USB Type-C

This new standard has a great future. First, he’s quick and can pass high currents, and secondly, it can be inserted on either side and at both ends of the wire may be the same connector.

In 2015, Apple shocked the world by releasing a MacBook with a single USB Type-C connector. This could be the beginning of a trend.

Now there are many devices with USB Type-C connector. To connect to a computer is to use USB Type-C to USB Type-A cable, if you do not have the same connector in the computer.

Buy cheap USB Type-C cables are not worth it, not worth it. Very easy to kill your device. Moreover, such cables are high current, so a poor quality cable and even lead to fire. Do not spare money for quality cable.


Today we looked at various types of USB connectors and standards. Now you are aware of all popular types of USB connectors. I hope this information was useful for you. If so, don’t be lazy, please rate this article below.
