USB Power Delivery

USB Power Delivery

USB Power Delivery (USB PD) provides the rules for generating power using USB-C cables, which have the extra wire over which USB PD communicates. USB PD defines five levels as follows. For example, a USB port rated at 50 watts supports 3 amps at 5, 9 and 15 volts, as well as 2.5 amps at 20 volts (50 divided by 20). See USB power, USB Type C and PoweredUSB.

Power Delivery Logos
These battery logos indicate that the port conforms to the USB PD specification. Use of these logos must be licensed by the USB Implementers Forum. The SS20 logo was created and included to provide continuity for the 20 Gbps version, but it is not an official USB-IF logo (see USB 3.2).
