Abstract
In a camera battery charger, a solar battery is provided upon a lid of a camera case, and a charging circuit for charging the in-camera battery by the solar battery or an external battery. When a camera is stored in a main body of the case, the in-camera battery is electrically connected to a power supply output terminal of the charging circuit, and is normally charged by the solar battery. When high-speed charging is necessary, the in-camera battery is charged at high speed by an external battery in an external battery adapter set in the main body of the case, or an external battery stored in an external battery storage part integrated with the main body of the case.
