USB-C plug USB-C (SuperSpeed USB 5Gbps) receptacle on a laptop. USB-C, or USB Type-C, is a 24-pin, reversible connector (not a protocol) that supersedes previous USB connectors and can carry audio, video, and other data, to connect to monitors, external drives, hubs/docking stations, mobile phones, and many more peripheral devices.
A USB cable, by definition, has a plug on each end—one A (or C) and one B (or C)—and the corresponding receptacle is usually on a computer or electronic device. The mini and micro formats may connect to an AB receptacle, which accepts either an A or a B plug, that plug determining the behavior of the receptacle.

For USB-powered devices, it is 5 volts. Later, battery charging protocols such as Quick Charge by Qualcomm and USB Power Delivery started allowing charged devices to request different voltages suited for their needs, usually higher voltages to increase power without adding heat to the copper wires of the USB cable. In the past, "SuperCharge" by ...

Quick Charge is a proprietary technology that can charge battery-powered devices, primarily mobile phones, at power levels exceeding the 7.5 watts (5 volts at 1.5 amps) supported by the USB BC 1.2 standard, using existing USB cables. The higher voltage available allows more power (watts) to be supplied through wires without excessive heating.
