I'll add, the R5c will ignore a USB PD power source if it cannot provide 9V. Current (A) though is drawn as needed and can be less than 3A depending on lens use (such as using manual focus).
Yes. I don't know the details of why but if the USB port isn't or can't supply enough power, the camera just ignores it and reverts back to the battery. It appears that it can use only one power source at a time.
Just to add to the data points, I connected my R5C with my RF 100-500mm, set it to 60 fps with IS and AF enabled, recording to a CF card and the power bank would occasionally flash 18W. It doesn't tell me any more specifics. The rest of the time it would show something less like 13W or 16W. I randomly assumed that would be the most power hungry lens.
