How much power can be wirelessly transferred using the AirFuel Alliance Standard?

The AirFuel Alliance Specification allows the transfer of up to 50 watts of power. Devices using this standard can operate at a number of power levels based on the required application. Below is a table taken from the AirFuel Alliance specification document that shows the different power levels.

Note: 6.5 W is intended to allow 5W at the charge port if the implementation has an efficiency greater than 80%.
