Anti-clickbait title: the US federal regulation limiting cell phone battery capacity.

If you want to skip the click through: 20Wh maximum

    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...

    If you read the article or regulation, you'll note that there are some ways to get around this by dividing the battery into cells.

    Also, that is a fucking hilarious "phone."

    phone specs are decently good enough for my needs these days that id be happy to just get something like this with low specs but a ridiculously massive battery capacity (as long as its as advertised, id look into it)
