1. A wireless power adapter comprising:

  • a first electric coupling member operable to couple to a power source;

    a second electric coupling member operable to couple to a legacy device;

    a wireless power receiver operable to receive electrical energy from a wireless power transmitter via a wireless resonant coupling link; and

    a controller configured to;

    determine whether the wireless power adapter has access to preexisting calibration data for supplying the legacy device with electrical energy;

    in response to the determination that the wireless power adapter does not have access to preexisting calibration data for supplying the legacy device with electrical energy, deliver a first power signal to the legacy device via the second electric coupling member, wherein the first power signal is received from the power source via the first electric coupling member;

    receive information indicative of a response of the legacy device to receiving the first power signal, wherein the detected response is indicative of at least one of;

    a voltage response, a current response, and a load impedance;

    based on the received information, identify a type of the legacy device;

    based on a power characteristic associated with the identified type of the legacy device, determine an operational configuration of the wireless power adapter; and

    configure the wireless power adapter to provide power to the legacy device according to the determined operational configuration.
