Abstract
An adapter for an electric power tool couples battery packs with the electric power tool. The adapter is provided with a voltage regulator circuit interposed between the battery packs and the electric power tool. The voltage regulator circuit regulates a supply voltage from the battery packs to the electric power tool to a level corresponding to a rated voltage of the electric power tool. The voltage regulator is capable of raising the supply voltage higher than nominal voltages of the battery packs.
