The Wireless Power Consortium (WPC) is a worldwide organization that develops and promotes
the global interface standard for wireless power transfer called Qi1. Interface standards ensure the
interoperability of devices that conform to that standard. Supported by more than 600 companies
and with thousands of certified products, Qi has become the international wireless-charging
standard for hand-held consumer electronics.
This document introduces the Qi Specification, which applies to flat surface devices such as mobile
phones and tablets that use up to 15 W of power.2
The WPC actively investigates new applications for wireless power transfer, such as a cordless
kitchen solution that uses Power Transmitters installed underneath countertops and tables that
enable a variety of kitchen appliances and smart cookware to operate without power cords.
