Abstract
An improved structure of power storage device comprises at least three power sources and an uninterruptible power supply (UPS) system. The at least three power sources comprise a commercial power service and anyone selected from a fuel generator, a solar power generator, a wind power generator, a battery generator, and a fuel cell generator. The UPS system has a built-in power source selector. The UPS system has an output terminal for coupling with an electric appliance and an input terminal for connection with the at least three power sources via the power source selector. As a result, the UPS system becomes a power supply and the built-in power source selector selects another power source during the commercial power interruption so as to enable the electric appliance to work normally until the commercial power interruption is over.
