@clacke The two have vastly different purposes and meaning (Ah being how long you can abuse the battery for, which Wh does not convey), plus bunch of standards mandate it AFAIR.

Is that how the mAh rating on powerbanks works, or is the A meant to be at the internal voltage like 7.2 V or something?Why do they even use Ah? Use Wh instead and avoid this confusion.
(the world is not ready for powerbanks rated in J)

e = mcΒ²
