The USB 3.0 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 100W over USB power delivery certified cables.

“USB power delivery enables a path to greatly reduce electronic waste by eliminating proprietary, platform-specific chargers. 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,” said Brad Saunders, USB 3.0 promoter group chairman. 

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. USB power delivery 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 publication of the USB Power Delivery specification is an important step in enabling a flexible, standardized power management ecosystem,” said Peter Harrison, director of standards collaboration at Nokia.

I wonder how many will try to pass 100W thru a regular 5V 500mA cable. It won't take long to make the cable in a dripping mass of molten plastic.

Either cables need to be rated all for the maximum the spec allows, or for what they can handle, else this has fire-hazard written all over it.
