Qi Low Power Specifications

The Qi low power specification is available as free public download from this website. See http://www.wirelesspowerconsortium.com/downloads/wireless-power-specification-part-1.html

This document defines the interface for contactless power transfer between a power transmitter and a power receiver, based on near field magnetic induction between coils.

The Wireless Power Consortium created two additional documents

• Performance Requirements Specification. This document defines performance requirements for power transmitters and power receivers.
• Compliance Test Specification. This document defines the compliance test procedure for power transmitters and power receivers.

The  Performance Requirements Specification and the Compliance Test Specification are available for members only. To join the WPC see: http://www.wirelesspowerconsortium.com/about/how-to-join.html
