USB 3.0 Gets New Power Delivery Spec, Can Deliver Up To 100 Watts
The USB 3.0 Promoter Group, alongside USB 2.0 Promoter Group, announced the completion of a new USB Power Delivery specification. This new spec will enable an increase in power delivery through USB cables and connectors. It will however require a USB Power Delivery-certified cable in order to put out higher voltages and current in order to deliver the 100 watts maximum specified. This should allow for the option to charge items such as notebook PCs, external hard drives, etc which couldn't be done before from traditional 5V bus power. A full list of specifications for USB 3.0 can be found here. Essentially this news boils down to one major change according to Brad Saunders, USB 3.0 Promoter Group Chairman, "We envision a significant move toward universal charging based on this specification, most notably for charging notebook PCs using standardized USB power bricks or when connected to USB hubs and desktop displays that integrate USB Power Delivery capabilities."

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.
