A portable power supplying device includes: a base; a terminal unit including first, second and third terminal sets disposed at first, second and third mounts in the base, respectively; a circuit switch operable in a selected one of a series connection state, where the circuit switch connects the first, second and third terminal sets such that batteries disposed at the first, second and third mounts are connected in series, and a parallel connection state, where the circuit switch connects the second and third terminal sets such that the batteries disposed at the second and third mounts are connected in parallel; and a switch control operable in a selected one of a non-power supplying state, where the switch control breaks electrical connection between an output terminal and the terminal unit, and a power supplying state, where the switch control makes electrical connection between the output terminal and the terminal unit.
