USB port able to charge and play music

So I work on boats and we have a costumer that would like to play music through his USB port. He is able to do that at the moment but it does not charge the phone as well and he would like it to be able to do that. A single USB port is hooked up with RCA plugs. Is that possible? I’ve been looking through our suppliers and haven’t found Anything that looks like it would be able to do that.

The USB 3.0 specifications goes up to 5V, 900mA, 4.5 Watt (and that, for the high end, the original specs are just 150mA, or 0.75 Watt).

Have you tried to get a portable Radio System with its own battery and supporting Blue Tooth (from the cellular phone) as example?
