The convenience of cordless power tools doesn’t come without a price – the hassle of multiple batteries and chargers. GreatNeck Tools offers a trim solution: OnePower, a new line of power tools designed to work with one universal battery source. The OnePower line consists of five commonly used power tools – a variable speed drill, a detail sander, an orbital polisher, a hand vacuum and flash-light – in addition to the battery and charger. The single battery source is an 18-volt detachable battery and charger which is interchangeable with the five cordless tools comprising the OnePower line.
