External power is via a "dummy battery"

Unfortunately the USB adapter only charges, does not supply power to the camera directly, nor does charging while the camera is being used, thanks to Carey Rose who answered my questions and did the test:

You are correct about the USB port - but external power is not via the USB port...

See page 308 of the GX80/85 manual - which mentions the "AC adaptor (optional)/DC coupler (optional)"... but unfortunately doesn't give the part numbers :-/

It is an AC to DC converter that feeds a "dummy battery". The two are connected by a wire that feeds through the "extra" little door in the battery compartment's "main" door.

The camera runs from the mains-powered dummy battery, the same way it runs from a regular battery. Panasonic frequently uses this method.

I've heard the Panasonic parts are DMW-AC8PP (power) and DMW-DCC11 (dummy battery), the same parts that are used by LX100, GX7 etc. There are 3rd-party alternatives that might be cheaper.

I can't personally verify that those parts are correct for the GX80/85 though - I dont have them myself and have never tried them.
