The AUX-in cable with 3.5 mm jack feeds music from any analog source directly to the Dayton Audio KAB boards, enabling audio play from almost any non-Bluetooth source. ?

The battery cable is for portable projects where AC or 12 VDC car power are not available. Multiple types of rechargeable batteries work with this cable and the board will charge the batteries when using an adapter with 15 - 24 VDC. Output wattage of the power adapter should never exceed 30 watts, as there is no under/over charging protection built in to the KAB boards. ? Using the on/off power cable and SPST switch cuts power to the entire board, but still provides power to the connected batteries for charging. - All international buyers are responsible for all tax, duties and/or customs fees.
