USB cables also are known as Universal Serial Bus are everywhere these days. We use them on a daily basis for charging our smartphones, tablets, portable speakers and cameras even connecting them with computers, and so on. Though, USB cables come in different shapes and sizes in spite of the fact that a lot of them works for the same purpose. In this blog, I will explain the different types of USB cables available in the market and give some examples where you can use them.

USB Type-A

USB Type A cables are quite common and can be found on almost every corner of USB cable. These cables are used to connect various devices such as mobile phones, cameras and much more to computers.

USB Type-B

USB type-B connectors are not entirely as common and adaptable as the others in this list. They are mostly used to connect scanners and printers to your computers. Type B cables have a square shape with bevelled edges on the top ends. However, they are still in use today but are being slowly phased out.

USB Type-C

USB Type C is the latest port that is found on the newer smartphone devices and offers faster data transfer rates than old and traditional USB versions. The biggest advantage of this cable is that it is reversible and can be plugged in either up or down. It has become a new standard for mobile devices but we have not reached there yet, as some smartphone makers are still using older micro-USB ports in the newer phones.


There was a time when Micro-USB was the standard for many devices a long ago but has phased out for the most part and succeeded by the micro-USB connectors. You will get to see them on older devices like MP3 players, cameras, and game controllers, among others.


Micro-USB connectors are quite small and allowed smartphone makers to start manufacturing slimmer devices. However, it is being replaced by USB Type-C. micro-USB is still the most common USB port found on most of the mobile phones, tablets and other devices these days. Almost every manufacturer around the globe has adopted micro-USB, with the exception of Apple and possibly a few other brands.
