Abstract
An electric power supply circuit that provides electric power to a mobile telecommunication device is provided. The electrical power supply circuit can be plugged in to a power grid or receive transformed energy from an alternate energy source. The electrical power supply circuit may provide converted electrical energy to a mobile telecommunication device from the power grid, the transformed energy or a rechargeable battery. Further, the electrical power supply can charge the rechargeable battery from either or both the electrical power grid or the transformed energy. A management module assesses the available electrical sources and the state of the electrical sources so as to switch an appropriate electrical power source to be input to the mobile telecommunication device.
