New Qi Standards Expand Wireless Charging Opportunities

23 February 2015

On Feb. 12, the Wireless Power Consortium (WPC) announced the release of two draft specifications to extend the capabilities of the Qi wireless power standard – “Volume II: Medium Power” to allow up to 15 Watt delivery, and “Volume III: Shared Mode” to allow multiple devices to be charged from a single transmitter.
