Manufactures label was very informative. Their statement "Output Capacity: 6200mAN/5V/31 Wh (Typical energy loss accounted)", was the most honest assessment that I have seen in the power bank market.
Edit actually that does seem right. Mah means almost nothing without noting voltage. That reviewer posted the label. Its 10000mah at 3.7v, which is the typical voltage of a lion cell. So it makes sense at 5v it would be closer to 6200 with losses accounted for.

Is 10,000mAh a real number? The pictures of the battery label say Output capacity 6,200mAh. Not really sure what the difference is.
One reviewer said this, but im not saying its accurate so take it FWIW:

they can also charge my surface book studio, which uses a 40w charger.
and it can probably charge any surface product. you might get a slow charging notice, just ignore it, it will charge it faster than the battery drain so youre good.
(some surface products use a 65w charger, but this one should still charge them)
I just placed another order, so this would be my 4th unit.
it also has a nice little phone stand.

It looks like the order's flatter profile with built in cable that can be used as lanyard is better. The new one is small but bulky and a detached cable.
The older one will feel smaller in your pocket.
Any idea if that means it's good? I had a "10,000" mah battery from another brand but one of the reviews said it was just a marketing gimmick because it was 2x 5000mah batteries together so you never actually got as many charges as someone would expect.
I highly doubt there's any pack out there that doesn't have 2+ cells in it. I'm not sure how having more than one pack would affect the number of charges. But if their number is accurate, that's more that enough to charge a flagship like the s25u 1.2 - 1.5x
