USB Type C

The latest and most advanced USB connector, introduced in 2014. Using a plug and socket slightly larger than Micro USB, Type C was designed to replace all previous USB versions. Type C plugs are inserted into the socket in either orientation, and instead of cables with a different plug at each end (A-to-B, A-to-Mini, A-to-Micro) Type C cables use the same plug at both ends.

More Than Just USB
USB Type C was also designed for more than just USB. For example, VESA's DisplayPort Alt Mode allows DisplayPort signals to ride over Type C cables. See DisplayPort and USB.

USB 3.1 - SuperSpeed+ and More Power
USB Type C cables support USB 3.1, which increased the transfer rate of USB 3.0 from 4.8 to 9.6 Gbps. USB 3.1 also handles up to 100 watts and can be used to charge a laptop computer.

Beware Non-Compliant A-to-C Adapter Cables
Because there are billions of USB Type A chargers and laptops in use, adapter cables plug into a Type A port at one end a Type C device on the other. However, Type C supports faster charging and can draw more current. As a result, if the adapter cable does not use the required 56K Ohm resistor, a Type C device might attempt to draw three amps and damage a USB Type A port, which can only deliver two amps.

The Mess Today
The goal for USB Type C is to have one plug and socket for all data transfer and mobile power connections.
