摘要
A replacement battery pack for an electronic device has a power storage section having a secondary battery. A power input section has at least one power connector for receiving electric power for charging the secondary battery while powering the electronic device. A power output/input section has an output terminal for receiving electric power from the power input section and for electrical connection to a connector of the electronic device to power the electronic device, and an input terminal for connection to an external power source for directly charging the secondary battery while the output terminal is disconnected from the connector of the electronic device. An input power switch circuit selectively inputs electric power to the power output/input section either from the power input section when the electric power is available therefrom or from the power storage section when the electric power is unavailable from the power input section.
