A battery charger is configured to use selective one of two or more power supplies including a commercial AC power supply and a DC power supply. An AC cable is fixedly secured to the body of the battery charger and a DC cable is detachably connected to the body of the battery charger. A single transformer is employed that has a first primary winding to which the AC power supply is connected a first switching element, a second primary winding to which the DC power supply is connected via a second switching element, and a secondary winding to which a battery pack to be charged is coupled.
