I tested the VECYS IC1209 countertop ice maker.

It takes 1h 20min to make a pound of ice, and draws 100 watts per hour average (max draw is close to 250 watts when heating the evaporators to drop the ice, and may surge to 350-800 watts for a second when the compressor kicks on).

I was surprised to find that my fridge/freezer door mounted ice maker only made 0.19 pounds of ice in the same time, justifying having a separate appliance if you need to make a lot of ice in a quick amount of time. [You will have to add more water and remove the ice every 1-2 hours, so it’s not for completely unattended operation…]
