1. A wireless power transfer (WPT)-enabled device, comprising:

  • a communications module configured to communicate with a second WPT-enabled device and to determine a WPT operating parameter associated with WPT between the WPT-enabled device to the second WPT-enabled device;

    a driver module configured to generate a power signal for charging the second WPT-enabled device according to the WPT operating parameter, the power signal having a first resonant frequency; and

    a controller module configured to adjust the first resonant frequency until the first resonant frequency is substantially similar to a second resonant frequency of the second WPT-enabled device.
