Use Host port for USB Power, Use OTG port for charging a battery?

Hello,

I am considering purchasing a Radxa Zero 3E but I have a question about battery power.

I want the unit to work like a phone. It has its own battery that keeps it alive, but if it gets plugged into a device that provides power, it will charge the battery. I theorized that I could have the host port be used to charge and have the OTG port have a USB-C battery pack.

I have no idea where to start, but I wanted to ask the community if they know of a way to do this at all? What are the challenges? Sorry for the vauge question but I wanted my radxa to be a mobile device and I keep seeing UPS devices that have their own charge port.

Thank you so much for any guidance/advice you can provide to this RADXA newb :slight_smile:
