Disclosed is a wireless charging device for portable electronic device. The portable electronic device has a circuit device that includes a battery. The wireless charging device includes: a wireless transmission unit and a logic control unit, a step-up/step-down unit, first and second reverse current protectors, and at least a supercapacitor electrically connected between the circuit device and the wireless transmission unit. The first and second reverse current protectors function to prevent reverse current and to switch. The step-up/step-down unit controls step-up conversion in discharging and step-down conversion in charging. The logic control unit detects if a load exists on an opposite side of the wireless transmission unit and controls the operations of the step-up/step-down unit and the first and second reverse current protectors. The supercapacitor absorbs surge occurring in each charging operation to prevent accumulated damage caused by the charging operations.
