Just re-confirm on GX85 (1st Panasonic MILC which can take USB power for in-camera battery charging) that a 5V 2.1A output USB power bank can charge battery internally.

I tried with 2 power banks, a 10000 mAh ASUS and a 20000 mAh from MaxPower.

But GX85 uses regular micro USB port.

AFAIK for models supports USB power supply (to charge battery or direct power supply), the camera has voltage converter inside to step up those usual 5V power bank. Similarly a reason to put in a 5V to 8+V voltage converter in case dummy battery be used. In your case I guess might either be a not reliable voltage converter, or a power bank issue.

I think our lovely member Michael Meissner has excellent knowledge on this issue. Might worth to look up his previous threads on this matter.

Hmm it may very well charge through the USB-c with a 5v, there's no way to tell without letting it sit with a dead battery for several hours and see if it charges. But i just hooked up one of my bigger  power banks which is a popular brand (Rav Power) and is 5v@2.1A and it still didn't work to power the camera with USB-c.

In fact it gave me a message on the camera screen saying "USB power supply is unavailable. Power supply is insufficient for the connected device." We know 2.1A is more than enough, which means it's the 5v issue. Maybe tomorrow i will hit up radio shack and see if i can find a DC to USB-c adapter to test it out with the 9v converter just to see if it works.
