An Ice Maker isn't also an Ice Keeper. You'd be better off with a camping fridge / freezer for the same wattage to actually keep ice frozen / or food or whatever. They make iceless-coolers in all different sizes and price points - we have this one - it averages around 60-75 watts. We use it when I find a good meat sale to stand all of the freezer bags up and pre-freeze steaks and chicken before vacuum sealing. https://www.amazon.com/EUHOMY-Refrigerator-Electric-110-240V-Portable/dp/B0BYZNH4NX/
