The adapter has an electrical male connector, an electrical female connector and a universal serial bus (USB) host connector welded onto a miniaturized board (1c). A carrier coupler separates the signal transporting the data of 230 Volts/50 Hertz and all other sector voltages. An alternating current (AC)/ direct current (DC) converter supplies the board with different necessary voltages from 230 Volts/50 Hertz.
