can anyone recommend on a power bank of 9000-1000Mah?

in addition , if there's one that can be charged and discharged simultaneously.

I would recommend you get a 10000mAh once, you can search it on Amazon, get the high ranking and good reviews one.

Remember with the standard industrial design, you will expect to get 30% conversion loss, so with a 10k mah, you will be able to get 7k mah for charge.
