Power cells, or generators, were a component found in many weapons, droids, starships, space stations, and other devices and technology that made use of electric currents. They were typically installed in devices that were required to be small and portable. The power cell (or multiple cells, in some devices) provided the necessary voltage for the circuits to function.[source?]
Resistance droids often operated for unusually long periods of time without recharging and thus were equipped with extended-usage power cells.[2]
