The USB 3.0 Promoter Group, in conjunction with the USB 2.0 Promoter Group, today announced the completion of the USB Power Delivery specification, which enables increased power delivery through USB cables and connectors. The specification expands cable bus power capabilities in USB applications, supplying higher voltage and current to deliver power up to 100 watts over USB Power Delivery certified cables. It is capable of delivering higher power to charge notebook PCs and power external hard-disk drives, devices which previously did not receive adequate power from traditional 5V bus power.

The USB Power Delivery specification enables a switchable source of power without changing cable direction. Existing USB cables and connectors are also compatible with this specification and will coexist with the USB Battery Charging 1.2 specification as well as existing USB-bus powered applications.
