In a camera that uses the same power supply as the drive circuit for camera operations such as film winding and rewinding, when charging the strobe while the camera drive circuit is operating, the power supply voltage must be set to the lowest power supply voltage of the drive circuit. A camera strobe charging device characterized by comprising a battery check circuit that compares an operating voltage with a reference voltage set higher than the operating voltage and outputs a charging signal when the operating voltage is higher than the reference voltage.
