Did a battery stamina test of the grinder today. I can say it will for sure do at least 360g of coffee, I stopped at that point because I got bored. I also think that most people would have recharged the motor unit by then. I have not charged it so when I have got through a mountain of ground coffee, I will do some more.
Very impressed though I honestly didn’t think it would do anywhere near that much.
The grinds look really good as well, very even, my phone camera doesn’t do it justice really.
