    The Watt-hour (Wh) rating may not exceed 20 Wh for a lithium ion cell or 100 Wh for a lithium ion battery.

    The difference between cells and batteries is that you have to have multiple lithium cells to make a battery.

    Edit: this is around 25000 mAh

      I’m guessing a pouch cell counts as ‘one cell’ vs. a larger battery pack with multiple cylindrical cells.

      It also explains why Apple does that weird thing with 4-5 batteries in a macbook…

      Does this mean the US doesn’t have powerbanks with e.g. 30000 mAh capacity?
