The external shape of the main body (10) of the charger is a substantially rectangular parallelepiped shape with rounded corners, and the maximum side length is about 10 cm.
A USB terminal (20) that is connected to an external power supply source and inputs power and an output terminal (30) that outputs power to an external electrical product are disposed on the side of the main body (10) of the charger. Inside, a battery for storing electric power and a control device connected to them for controlling the input / output of electric power are arranged.
The power input USB terminal (20) is used by connecting to a PC, for example, and the power output terminal (30) is used by connecting to a mobile phone, for example.

A commercially available dry battery can be used as the battery. For example, two AA alkaline batteries are used, and a concave portion for accommodating the batteries is provided in the main body (10).
As a built-in battery type, a chargeable / dischargeable secondary battery such as a lithium ion battery, a nickel cadmium battery, or a small sealed lead-acid battery may be used. When the battery is a detachable secondary battery and the battery can be supplied with power input from the power input USB terminal (20), it can be removed when the battery is stored and used for another purpose. It becomes possible.

The control device connects the external power supply source to the external power supply source according to whether the power input USB terminal (20) is connected to the external power supply source and is in the energized state. A switching control circuit is provided that outputs power from the battery to an external electrical product, and outputs power from the battery to the external electrical product if it is connected to an external power supply source and is not energized.
