What is WPC and PMA?

A. W. A designation for trimode phone cases that supports three wireless charging protocols. WPC (Wireless Power Consortium) governs the Qi protocol. PMA (Power Matters Alliance) became AirFuel Inductive, and A4WP (Alliance for Wireless Power) developed the Rezence method, which evolved into AirFuel Resonant.

What is PMA charging?

Power Matters Alliance (PMA) was a global, not-for-profit, industry organization whose mission was to advance a suite of standards and protocols for wireless power transfer for mobile electronic devices (specifically a type of inductive charging that competes with the Qi standard).
