Abstract
Provided is an electronic device which is selectively connectable to two or more power sources thereby to charge the battery therein, and when connection with one power source is discontinued, the electronic device promptly switches connection to another power source thereby to start battery charging. When the external device connection section 290 becomes connected to an external device, while an AC connection section 300 is connected to an AC power source, a control section 210 performs initial communication with the external device thereby to perform charge setting necessary for charging a battery 310 via the external device.
