Abstract
A power storage device includes an input terminal, an output terminal, a first circuit, and a second circuit. The input terminal is to be electrically connected to a power supply. The output terminal is to be electrically connected to a load. The first circuit and the second circuit are electrically connected in parallel. Each of the first circuit and the second circuit are disposed between the input terminal and the output terminal. The first circuit includes a power storage unit and a discharge path that allows a discharge current from the power storage unit to flow toward the output terminal. The second circuit includes a blocking path that prevents the discharge current from flowing toward the input terminal.
