A portable wind-driven electricity generation device is provided herein, which mainly contains a fan, a generator assembly, a primary rechargeable battery, a secondary rechargeable battery, and an auxiliary driving assembly. When there is wind, the wind would drive the generator assembly to continuously charge the primary and secondary rechargeable batteries. The electricity supplied from the generation device is drawn from the primary rechargeable battery only. When there is no wind and when the primary rechargeable battery is not yet fully charged, a motor of the auxiliary driving assembly can be engaged from the stored electricity of the secondary rechargeable battery to drive the generator assembly so that the primary rechargeable battery can be as much charged as possible.
