Hi,

I'm trying shooting star trails tonight with the M6ii from the back yard.

Any thoughts on whether I'd be better off using the using the Canon battery or this battery through USB?

Power Delivery Power Bank 26800mAh, PD Power Bank, Charmast 18W USB C Portable Charger Quick Charge 3.0 Battery Pack

Correct me if I'm wrong, but I thought the M6 Ii only allowed charging over USB, not power over USB.

Unfortunately, I was overly optimistic and you seem to be correct. I had tested the concept before posting and thought I had power with the battery removed and battery door closed, but on retesting, I couldn't replicate it.

I can definitively confirm you that they are correct. Canon won't let the camera operate while charging. You'll need to switch to the Sony system to do that. When I owned the a6300 and a6400, I always carry a regular power bank (not PD type) and shoot while charging the battery. There's no need to buy a spare battery. But this may still not achieve your goal as I found the camera drained the battery faster than the power bank could charge it even with a 2.4A output at the time. That means the battery will eventually go to 0% if you do this for too long. Charging while shooting did prolong the battery life though. Maybe some higher end power banks are better now? I don't know.
