Unlike the very rugged copper-wire-wrapped-around-an-iron-core internal transformer inside a stereo system which recent discussions on Tachlis seem to indicate will operate without problems when plugged into an external transformer, the precision electrical components inside the battery charges of battery-powered power tools are often sensitive to AC frequency.
