Abstract: A power adapter for powering battery-operated (also referred to as “cordless”) power tools using electricity from a standard AC electrical outlet. Cordless power tools are typically powered by a battery cartridge which is removeably attached to the power tool. The battery cartridge includes a housing which contains the battery cells and electrical connections for electrically connecting the battery cartridge to the power tool. The power adapter of the present invention replaces, at least temporarily, the battery cartridge and comprises a housing which contains a transformer for converting the alternating (AC) electrical current to the same direct current (DC) electrical power provided by the battery cartridge. The power adapter further comprises electrical connections adapted to connect to the electrical connections of the cordless power tool. The power adapter housing has substantially the same overall size and shape as the battery cartridge which it replaces.
