Power supply via USB possible! +++ Best for Spotify on each plant

I bought this Bluetooth Adapter mainly for the surround system in the living room. Here works the Impeccable. Easy to connect (with me with the iPad and an Android smartphone) and good quality.

Since the Smart my wife no Bluetooth is present there I looked for a way to get the adapter up and running. A cable for cigarette lighter on the dashboard does not look great and much thus out.

I tried to take the USB port as a power supply and the AUX input for audio transfer. I must say it works just fine! Even on my system at home I take care of the unit via USB and thus spare myself an electrical outlet.
