The Wireless Power Consortium was founded on December 17, 2008. It is a cooperative organization composed of multiple independent companies. It aims to create and promote the market's widespread adoption of the international wireless charging standard Qi that is compatible with all rechargeable electronic devices.

Current situation

WPC has introduced the Qi certification rules, which stipulates product technical specifications, test specifications, certification process and use of certification marks. Qi certification is currently mature and popularized for short-range electromagnetic induction low-power devices. In 2016, WPC has updated the standard to version 1.2.1, and now no longer accepts product certification for the old version 1.1.2. The new version of the standard already covers the transmitting and receiving devices with 15W fast charging function.
