Abstract: An adapter includes a cord, a fitting portion, a voltage setting unit, and a fitting prevention mechanism. The cord is adapted to connect to a DC power source unit in order to receive DC voltage from the DC power source unit. The fitting portion is for insertion into the battery holding space of any one of a plurality of cordless power tools. The fitting portion receives the DC voltage received through the cord and supplies the DC voltage to a cordless power tool in which the fitting portion is properly inserted. The voltage setting unit is for setting voltage supplied through the fitting portion to the cordless power tool. The fitting prevention mechanism operates in linked association with operation of the voltage setting unit to prevent proper insertion of the fitting portion into a cordless power tool that has a rated voltage different from the voltage set by the voltage setting unit.
