Standard set for universal wireless charger

ZDNet - The Wireless Power Consortium has finalised a standard for wireless charging of mobile devices, bringing universal charging for products one step closer to reality. On Friday, the trade alliance said that it has agreed upon specifications for three key areas of the Qi low-power standard, which is based on magnetic induction technology. The three areas are interface definition, which outlines the requirements for power transfer between the transmitter and receiver; the performance requirements; and the test procedure for compliance with the standard.
