Technically an option for sure. With the Silkroad-special model sold through Amazon the manufacturer decided to have the adapter turn off during charging. So listening to music while the adapter being plugged in is not possible unfortunately.

Still use this to this day in my car - although the Bluetooth variant. The only downside is that you need to recharge it from time to time. That problem has been recently solved by the purchase of a second one :)

What a time to be alive. Truly an age of wonders.
