Abstract: A power supplying apparatus includes a voltage outputting module and a voltage selecting module. The voltage selecting module is electrically connected to the voltage outputting module. The voltage selecting module includes a returning unit. The voltage selecting module receives a voltage identification signal when the voltage outputting module is electrically connected to an electronic device. When the voltage identification signal is larger than a voltage level, the returning unit notifies the electronic device, such that the electronic device returns a voltage request signal. The power supplying apparatus selectively sends out one of a plurality of DC voltage signals to the electronic device according to the voltage request signal.
