The USB 3.0 Promoter Group, in conjunction with the USB 2.0 Promoter Group, has 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’s capable of delivering higher power to charge notebook computers and power external hard-disk drives, devices which previously did not receive adequate power from traditional 5V bus power, according to Brad Saunders, USB 3.0 Promoter Group chairman.
The USB 2.0 and 3.0 Promoter Groups developed the USB Power Delivery specification and have transitioned the specification’s management to the USB-IF. The USB Promoter Groups are now accepting adopters of the USB Power Delivery specification.
