This technology employs a secure and cooperative power sharing method. It comprises of wireless resonant inductive power receivers that use a public authentication key protocol. Each receiver includes a public key that securely pairs with a private key only owned by a compliant charger, allowing for multiple devices to connect to one charger. The receivers also have a wireless detuning function to control the amount of power received from a charger based on different operating conditions (i.e., proximity and orientation of devices to the charger). This detuning functionality is possible through resonant frequency modulation between the two coupled coils in a receiver.
