    mAh is a stupid way to measure batteries. Wh is more relevant.

    It also tells nothing about the efficiency of the device. You can add a 50kWh battery to a device but it doesn’t matter if it uses 2kWh at idle

      I’d argue Wh is a complete waste. Just use J, which is the much more established unit.

        I disagree. Joules are really hard to understand to laypeople. Watt-hours directly relate to the power of a device without conversion, and can even be really translated in terms of power bill.

        3.6 megajoules? Eh, I guess that’s maybe a lot? Or not?

        1000 watt-hours? Oh, like running a microwave for a whole hour? Dang that’s a LOT!
