GH5 Powering the GH5 with an AC power bank

[mmaller]

Has anyone used a power bank with an AC outlet to power their GH5 for extended recording times?
I want to use Panasonics GH5 AC power adaptor which uses a dummy battery and then plugs into the Panasonic ac convertor.
Can I plug this into the AC outlet on a power bank like the (OMARS 88w 24000mAh Power Bank) and then power the GH5?
How long would the GH5 run using this setup?

The reason for this is no access to wall current but need extended continuous recording times.

You'd have less cables to deal with if you used a DC power bank and a dummy battery.

I use this https://www.bhphotovideo.com/c/product/1148546-REG/atomos_atompws002_atomos_power_station.html and it works very well. One battery lasts close to 4 hours so go almost a day on two, you can hot swap so go continuously if you have enough L series batteries.

I almost got that power bank, it's one of the few which can do 9v out.

But... then i found this gem:

An f970 with a built in 9v out. brilliant i tell you

It powered a GH5 for 8 hours doing a 10 second interval timelapse. When i got home i put it on an led light to see how much longer it would go, and it went quite a bit longer.

Not sure how long it would go doing a regular recording, if OP is interested i could do a test with my gh3 on hand

Very cool idea, as 5 volt USB battery packs are cheap and easy to find.
