USB-C is a 24-pin USB connector system with a rotationally symmetrical connector. The USB Type-C Specification 1.0 was published by the USB Implementers Forum and was finalized in August 2014. It was developed at roughly the same time as the USB 3.1 specification.

What is the difference between USB and USB-C?

USB-C features a new, smaller connector shape that's reversible so it's easier to plug in. USB-C cables can carry significantly more power, so they can be used to charge larger devices like laptops. They also offer up to double the transfer speed of USB 3 at 10 Gbps.

What is USB-C used for?

This is much faster than any other sort of USB connector. USB-C cables are also used to transfer power — they're commonly used to charge portable devices, smartphones, laptops, and even security cameras. A standard USB-C connector can provide 2.5 watts of power, which is the same as most USB-A connectors.
