I have a usb dac that I wish to couple to my smartphone. Of course, the phone's usb port is also its charging port. The solution is to get an OTG power cable so that I can charge my phone and listen to music at the same time.
However, I'd like a docking station that I can slot my phone in, couple it to the usb dac and also charge the phone. Before I spend money on the wrong thing, I'd just like to know if such a thing exists? I've looked online at various docking stations but I find there's insufficient information to answer my question.
