USB ports are input/output devices that also charge. Regardless of what it's intended for, you can still use it to charge a Bluetooth device. I have used a television USB port to charge my iPod.
Also, I have a set of headphones for use with my laptop that have a USB plug instead of the typical RCA stereo plug. Got it at Best Buy in the computer gaming section, not the audio section. I haven't tried using it with my Airstream's television, but you might consider something like that.
