A power supply for a power tool which is adapted to be powered by a battery source and an AC voltage source includes a battery module constructed and adapted to be removably coupled to the power tool. The battery module includes a battery pack for supplying power to the power tool. A power converter module supplies current for charging the battery pack and for operating the power tool. A power plug extends from the power converter module and is adapted to be connected to the battery module. The power plug has a first output for supplying the tool operating current to the power tool and a second output for supplying the battery charging current to the battery pack when the plug is connected to the battery module. A switching device is provided in the battery module for electrically disconnecting the battery pack from the power tool responsive to the plug being connected to the battery module.
