AirFuel

AirFuel is a global standards organization that promotes wireless power transfer for consumer electronics and other devices. It coordinates the AirFuel Alliance, which develops specifications, conformance tests, and certification programs to enable interoperability among wireless chargers and recipients. The organization supports two main wireless power technologies designed for mobile and embedded devices: inductive charging and resonant charging, allowing devices to be charged without direct electrical contacts.

AirFuel was formed in 2015 through the merger of two prior groups: the Power Matters Alliance (PMA) and the Alliance for Wireless Power (A4WP), the latter known for its Rezence technology. The consolidation aimed to unify competing standards into a single framework and to promote broad ecosystem support across manufacturers and accessory makers.

AirFuel Inductive is based on tightly coupled magnetic induction, typically requiring close alignment between transmitter and receiver coils. AirFuel Resonant uses magnetic resonance to enable charging with looser alignment and over greater distances, expanding usage scenarios such as cluttered surfaces or multi-device pads. Together they define electrical and mechanical requirements, test methods, and interoperability guidelines; devices that meet the standards can seek AirFuel certification.

Market adoption of AirFuel has remained more limited relative to the Qi standard developed by the Wireless Power Consortium. Some manufacturers support both AirFuel and Qi, while many mobile devices rely primarily on Qi. AirFuel has pursued applications beyond phones and wearables, including automotive, industrial, and IoT devices, and continues to develop specifications and ecosystem programs to foster interoperability.
