Here's a good previous thread...

I have a dummy battery (with voltage adapter) similar to the one you linked to. It works just fine with my M6ii.

But as mentioned, your power bank might be a bit on the light side. Ideally you'd want an output spec of 2.4 amps @ 5 volts. I have several with this spec and they all work great.

The power bank you have is worth a shot though since you have it already, but that 5000 mAH spec is most certainly inflated (your power bank appears to be based on a single 18650 Li-ion cell). Current top shelf NCR/Panasonic 18650 cells max out at about 3400 mAH.

Plus, that rating is at 3.7v, not the 5v that it must be boosted to charge/run devices.

That's a given.

Not to the general masses that read those numbers (sadly).

Actual capacity will be less.

Waaay less once you figure in the conversion loss!

Yup!
