Wireless charging scheme delivers 300 W over 40 mm

Eggtronic has announced E2WATT, a new AC power technology that will boost the power, efficiency, charging distance, and data transmission capabilities of wireless charging applications.

Offering efficiency comparable with the best conventional wired AC adapters, E2WATT provides the foundation for taking future mobile charging designs into new segments including laptops, AV equipment, and even home appliances and electric vehicles.

Traditional Qi wireless power is limited by distance (usually 5 mm), and maximum power (usually up to 30 W). E2WATT technology reaches up eight times further (to 40 mm) and delivers up to 300 W – a real breakthrough for inductive standards.

E2WATT wireless technology is powered directly from AC mains, without the need for an external power supply. The single-stage hybrid design minimizes losses compared with conventional double-stage wireless technologies to deliver significantly increased peak efficiencies of up to 95%.

These extremely useful features ensure a reduction of the global cost of the solution, an increase in performance and usability, and a smaller carbon footprint. Additionally, thanks to the proprietary receiving technology, the platform allows for a significant drop in receiver temperatures. The charging performance of modern smartphones and laptops is therefore improved, resulting in a better user experience.

E2WATT AC wireless power supply enables the creation of new scenarios. Several products based on the technology are currently being released while consumer, industrial and automotive solutions are in parallel development.
