A wind power charging device for a portable electric apparatus is provided. The wind power charging device includes a fan, a power transformation device, a switching device, a rechargeable battery, and an output terminal. The fan rotates according to wind power and generates rotation power. The power transformation device transforms the rotation power to electric power. The switching device receives the electric power and outputs a first charging voltage. The rechargeable battery is charged by the first charging voltage and discharged to output a second charging voltage. The output terminal receives the first charging voltage and the second charging voltage and outputs a third charging voltage. The switching device selectively outputs the first charging voltage to one of the rechargeable battery or the output terminal. |
