The USB 3.0 Promoter Group just revealed it is working on a new power delivery spec for USB cable bus power that will deliver much more power for charging or powering electronics devices. The standard will exist alongside the USB Battery Charging 1.2 specification and deliver up to as much as 100W of power. It will also continue to work with USB 2.0 and original USB 3.0 standards as well as current cables and connectors.
