A:AnswerThere is no specific wattage/power rating on the output of this unit, due to variations in the level going into it from the connected Bluetooth device. It requires a direct connection on a car stereo thru a 3.5mm input jack, and does not transmit to the radio's FM tuner wirelessly.
A:AnswerBest Buy sells one that plugs into your charging port(or cigarette lighter) and works off and unoccupied radio station. We have one of those as well and it works great! Around $25.
