Very few power banks can properly power a Pi. I actually don't know of any that can power a Pi 4/5. Some can easily power a 0, but that's not what you're trying to do.
If you need to run a Pi from batteries, probably the easiest thing is a power tool battery and a buck converter. If you have a power tool you already have the battery and the charger, you just need an adapter (if you care to keep things neat).

In another I asked the member who put that together how long that battery would last, and for his use he had said he once got it to run for many hours. Obviously how long it will last depends on the kind of load you'll have on your pi.
I used this adapter for a Ryobi battery and it worked great: https://www.amazon.com/RVBOATPAT-Batter ... C79&sr=8-8
Edit: lesson learned. Next time research before you buy.
