10000 mAh power bank. 10000x.74x.85 = 6290 mAh

(This will be your average /standard output of 10000 mAh power bank) assuming it to be 85% efficient. 10000x.74x .90= 6660 mAh (90 = 90% efficient .85 = 85%)

What is efficiency?

In simple terms, Layman terms, there are losses in transfer from one battery to another on common losses being due to circuit losses. So, in reality a 10000 mAh power bank will give below 6500 mAh capacity.
