Definitely need to swap over to some other power source, as 9v battery will cost more than the unit!

There are 9V Batteries you can recharge from usb-c. Maybe an option.

I think your power supply idea is great.
I probably have 50 different power supplies from old devices. I keep them in a box, each one is labelled with output voltage and current. Use them for projects all the time.

Just double check the polarity!
I’ve had at least one fro the 90s that was shell + pin - opposite from most.
