New USB Power Specification – Dreamy
Cell phone standards ditched the AC/DC adapter about a year ago and it’ll be a requirement all cell phones power only via USB. Now it looks like we could do the same for computers. The USB 3.0 Promoter Group introduced a new specification to offer up to 100watts of power over a USB 3.0 cable. How convenient would that be!
“Building on the rapidly increasing industry momentum for using USB bus power to charge a broad range of mobile devices, the new USB Power Delivery specification extends USB’s cable power delivery capabilities beyond simple battery charging,” said Brad Saunders, USB 3.0 Promoter Group chairman, in a statement. “For example, charging the battery of a notebook PC, or simply powering that notebook PC while actively using the USB data connection, would be possible. Conceivably, a notebook PC could rely solely on a USB connection for its source of power.”The preliminary spec indicated power is bi-directional and therefore no need to switch or swap the USB cable. The new specification would be compatible with existing cables…and if this isn’t good enough, the specification is also compatible with USB 2.0 and 1.0 standards. USB 3.0 was first announced in the first quarter of 2009 and began shipping product in middle of 2010. Now in 2011 the momentum of USB 3.0 is taking hold.
