Abstract
A battery charger for charging a detachably attached battery pack by supplying an electric power from an external power source, the battery charger includes a notification unit for notifying a user of a charging operation by turning on or flickering a light-emitting member. The notification unit notifies the user of a power connection state of the battery charger by turning on or flickering the light-emitting member immediately after the battery charger is electrically connected to the external power source without attaching the battery pack thereto, and the notification unit turns off the light-emitting member after a predetermined period of time lapses and keeps the light-emitting member in an off-state until the battery pack is attached to the battery charger.
