Power by Contact technology

energysquare’s Power by Contact® charging solution works by electrical conduction :
It consists of a transmitter and a receiver.
– The transmitter is made of conductive tiles monitored by a transmitting circuit, controlled by a detection algorithm and a charge monitoring system.
– The receiver is a device equipped with two conductive electrodes, monitored by a receiving circuit, connected to the device’s battery.
The technology works through the contact between the receiver’s electrodes and the transmitter’s tiles : the transmitter will detect the receiver, communicate with it and activate the appropriate power.


Charging made easy

The solution

Energysquare has developed the most powerful, reliable and efficient wireless charging technology on the market. Unlike all other technologies developed so far, Power by Contact makes it possible to charge several devices simultaneously, at the same efficiency and speed as a cable, with high power, and at an extremely reduced cost. It is the first technology capable of charging any laptop wirelessly. Winner of the CES 2019 “Best of Innovation Award” in competition with 4000 exhibiting companies.
