Wireless Power charging describes technologies that enable battery charging of mobile devices without a power cable.

About wireless power charging

There are two different ways of wireless power charging

  • via electromagnetic induction
  • via magnetic frequency resonance

The Wireless Power Consortium (WPC)

The Wireless Power Consortium currently supports the electromagnetic induction method and is going to support the resonant charging technology in due course as well. It combines

  • inductive technologies transmitter and receiver coil – placed no more than 7 mm from each other
  • resonant charging technologies transmitter detects and charges mobile devices at a maximum distance of 45 mm

By incorporating both methods, all products that are Qi certified” according to the specifications of the Wireless Power Consortium, cover a large range of use cases.
