1. A method of charging a wireless device, the method comprising:

  • converting electrical power at a first voltage to a second voltage using a converter, the electrical power at the first voltage being received from a battery electrically connected to the converter;

    supplying the electrical power at the second voltage to at least one transmitting coil of a time-displaying device, the at least one transmitting coil being electrically connected to the converter;

    transmitting the electrical power at the second voltage by inductive electrical power transfer from the time-displaying device to a wireless receiver which stores the electrical power, the transmitting of the electrical power including coupling the at least one transmitting coil of the time-displaying device to a receiving coil of the wireless receiver by varying a frequency of an oscillating magnetic field of the at least one transmitting coil so as to induce an alternating current in the receiving coil; and

    transferring the stored electrical power through a charging port of the wireless receiver to the wireless device,wherein the time-displaying device is configured to be worn by a user.
