A recharging apparatus applied to a portable electronic device. The recharging apparatus is capable of selectively enabling or interrupting the recharging procedure for a rechargeable battery in the portable electronic device. The recharging apparatus includes an input unit, a recharging circuit, and a control unit. The input unit is applied to generate a switching control signal; the recharging circuit is applied to receive an enable signal and then output recharging power used for recharging the rechargeable battery; and the control unit, electrically connected to the input unit and the rechargeable battery, is applied to determine whether to output the enable signal to the recharging circuit or not in accordance with the switching control signal.
