1. A battery pack powered device comprising:
a circuit configured to provide a power output, the circuit including:
at least one capacitor,
a first switch connected between a battery pack and the at least one capacitor, the first switch operable to control whether power is provided from the battery pack to charge the at least one capacitor, and
a second switch connected between the at least one capacitor and the power output, the second switch operable to control whether power is provided from the at least one capacitor to the power output; and
a controller configured to control the first switch and the second switch based on a voltage of the at least one capacitor.
