The one we have is brand named Igloo but it looks like and has the same specs as this amazon one people are
posting about. It seems to peek at about 400 watts when the
compressor starts but settles down to about 200. It runs fine on our modified sine wave
inverter, but is a little slower at making ice when doing so than it is on
shore power or the genset. We have found that placing a towel on the top improves the rate of ice being made and slows the rate of melting in the basket as the lid is not really insulated. We have 640 watts of
solar and we are well into absorption by 11 am and can run the ice maker all afternoon on what we would normally be throwing away except on cloudy days. We bag up the ice and put it in the
freezer. We are very popular while cruising as we always have ice. Being a cat we can use it while underway. I don't know how much heel it would be able to take and keep working.
We used to have a built in U-line which was basically worthless on the hook. While it would keep ice on the inverter it would not make ice on it. It was basically a drink fridge and it took lots of
power. When it broke I ripped it out and made a tool locker out of its space. I should have done it years before.
