Power that crosses the air, efficiently.
AirCharge builds near-field wireless power transmission units. Our designs are grounded in theory and lab experiments on what actually drives efficiency: coil geometry, distance, resonance and core materials.
The problem
Cables wear out, connectors fail, and e-waste keeps growing.
Charging cables and connectors are a constant point of failure in homes, hospitals and factories, and they add to the world's fastest-growing waste stream. Wireless power can help, but only if efficiency stays high as distance grows.

How it works
Engineering every parameter that matters.
Our research separates the factors that make or break near-field wireless power.
Model
Magnetic field intensity from circular loops is calculated at different axial distances using the Biot–Savart law.
Build
Coils of different radii are wound and their field intensity and resonant frequency measured.
Extend
Curved solenoids with magnetisable cores and capacitive plates are tested to increase transfer distance.
Optimise
Findings guide the coil, core and frequency choices in each AirCharge unit.
Product
What makes AirCharge different.

FAQ
Questions we hear often.
How far can AirCharge transmit power?
AirCharge uses the near-field technique, designed for short distances. Our research tests cores and capacitive plates to extend that range.
Is wireless power safe?
Near-field systems use low-frequency magnetic coupling over short distances; products will be designed to meet applicable safety standards.
What affects efficiency most?
Coil radius, distance between coils, resonant frequency and core materials, the exact parameters our research measures.
Can we co-develop a product?
Yes. We welcome partners who need a custom wireless power unit for their device.
Let's cut the cord together.
We are looking for manufacturing and product partners to bring AirCharge units to market.
