The PMA Alliance's technical approach is similar to that of the Wireless Power Consortium(WPC) and, like them, relies on magnetic induction( MI). The PMA Alliance develops an open PMA standard and certifies globally interchangeable products with a specified energy efficiency. The PMA solution uses a different protocol than the Qi standard and is incompatible with it as well as with the Alliance for Wireless Power( A4WP) concept.

In spreading the PMA standard, the PMA Alliance is relying on partnerships of restaurants and hotels, on the equipment of meeting tables that will be equipped with wireless power.

In 2015, the Alliance for Wireless Power (A4WP) and the Power Matters Alliance (PMA) merged. The new alliance is called AirFuel Alliance.
