What are the different types of USB cables?

Last Update Date : Apr 12. 2018

There are a number of different USB cables each of which has different benefits and is suited to a different task.


USB-A

 

USB-A is most commonly used with computers, or power outlets, and can be used for charging devices, connecting devices to computers or data transfer. The USB-A can only be plugged in one way.

USB-B


USB-B ports are mostly used to connect printers or external hard drives with computers. They are not as common as the other types of USB cables.

 

B 

 

USB-Mini

 

The USB-Mini was used for connecting mobile devices including MP3 players and cameras, and is a much smaller connection, thus allowing smaller devices.

USB Micro


The USB Micro is now the standard USB port for almost all mobile devices. This type of connection allows data to be read without needing a computer. For example, you are able to connect Flash Drives, or Memory Sticks, directly to your mobile device.

USB-C

 

USB-C is on of the most recent USB development. It allows high speed data transfer and a high power flow, and is reversible and so can be plugged in either up or down.

USB 3

 

USB 3 was designed to be able to be backwards compatible with earlier versions of USB cables and ports. The USB 3 has different shaped connector pins so it can withstand more frequent use. The USB 3-A and USB 3-Bcables are identical to the USB-A and USB-B cables at the top of this article, except they are coloured blue inside to distinguish them. The USB 3 micro cable has extra pins to enable the transference of more data.
