1. A power source device, comprising:

  • a power source;

    a short range wireless communication receiver for wirelessly receiving information signals transmitted from at least one power charge device;

    a wireless power transmitting circuit, the wireless power transmitting circuit having a frequency pass band about a resonant frequency and electrically coupled with the power source, for selectively coupling charging energy from the power source to the wireless power transmitting circuit and thereby wirelessly transmitting a charging energy signal having a frequency substantially within the frequency pass band; and

    a charging power controller, communicatively coupled with the wireless power transmitting circuit and the short range wireless communication receiver, the charging power controller configured to;

    wirelessly receive, by the short range wireless communication receiver, at least one information signal transmitted from the at least one power charge device;

    determine whether the at least one power charge device is in a charging arrangement with the power source device;

    selectively couple charging energy from the power source to the wireless power transmitting circuit; and

    control the wireless power transmitting circuit to wirelessly transmit the charging energy signal having a frequency substantially within the frequency pass band.
