Abstract

An electric apparatus according to an embodiment includes a plurality of connection devices connectable to a plurality of external power supplies; a battery; a charge circuit to charge the battery using electric power supplied from the external power supplies; a plurality of switch sections each connected between the connection devices and the charge circuit; a storage section to store therein a priority degree for supplying power to the battery for each power supply type of the external power supplies; and a controller to control power supply from the external power supplies to the charge circuit. The controller detects power supply types of the external power supplies connected to the connection devices, and compares priority degrees corresponding to the power supply types detected and switches off the switch sections of the connection devices that are connected to the external power supplies except an external power supply having a highest priority degree.
