AirFuel Resonant

How It Works

Resonant charging works by creating a wireless transfer of electrical energy between two coils, tuned to resonate at the same frequency. Based on the principles of electromagnetic coupling, resonant-based chargers inject an oscillating current into a highly resonant coil to create an oscillating electromagnetic field. A second coil with the same resonant frequency receives power from the electromagnetic field and converts it back into an electrical current that can be used to power and charge devices.

AirFuel members are using Resonant technology each and every day to create wireless charging products and solutions that deliver compelling end-user experiences.

Key Benefits

Resonant technology offers a number of unique advantages that helps power devices from wearables to mobile phones and notebook computers all the way up to automobiles and beyond.

Spatial Freedom

Resonant technology let’s you power over a distance – from up to 50mm high and across a wide surface area. No need to match up the device and charging coil precisely (as with other technologies). Resonant gives users the freedom to continue working or playing while still charging.

Multi-Device Charging

With Resonant, you can charge multiple devices, with different power requirements, at the same time from one PTU power source. This gives consumers a common charging source for the multiple devices in their connected lives.

Easy Installation

You can transmit power through a variety of materials with Resonant – everything from wood to stone to concrete. This means the PTU charger can be mounted under a desk or table, or embedded in the concrete of a garage floor vs. being drilling into surfaces, making it easier to install.

Flexibility & Efficiency

Resonant delivers the low power (milliwatts) and smaller footprint needed for applications such as wearables all the way up to higher power (kilowatts) needed for EV charging and beyond.

Resonant in the Real World

AirFuel Resonant technology is used by the world’s leading mobile chipmakers, mobile phone manufacturers, and other key industry partners to deliver products and value-added services like mobile payments, gaming, advertising, peer-to-peer data sharing and location based services, to name a few. Here are a few great examples …
