A multi-functional charger with power generating and illumination functions comprises a device body, a gear set, a generator, a voltage and current control loop, a battery, and a movable rod. When the movable rod rotates, the generator will operate by the driving of the gear set so as to generate a current. The current is suppressed, rectified and regulated by the voltage and current control loop. It can be determined to be stored in the battery or outputted through a plug by the switching of the switch. The power stored in the battery can be supplied to the LED lamp or to be outputted. When the power is outputted, a plug serves to be connected to an electric device to be charged. To achieve the requirement of illumination, the generator is connected to an external bulb set. Thereby, the charger can be used in various applications.
