The Wireless Power Consortium took a big step forward this past week with the confirmation that its precocious Qi interoperability standard has been finalized. Composed of three documents setting out the interface, performance and compliance requirements, the new dictum has set itself the not inconsiderable challenge of making wireless charging universal, so that any Qi-approved phone can soak up juice from any Qi-verified base station, dock or omnitool. This first spec is limited to devices requiring no more than 5 Watts, an appropriately humble early goal, though cauldrons are already bubbling with ideas for laptops and the like. We just hope the impressive list of big time companies on the Consortium will succeed in taking Qi into the mainstream -- who here hasn't dreamt of their phone being compatible with the Touchstone?
