I had a Waeco CF50 for a while and used it as a cheaper alternative to getting a new built in freezer
. It was used to store frozen food
not for making ice cubes. The ice cube usage certainly would require something like 3 hours running at max to make a few trays of cubes.
If you get one, there are 3 factors to wach out for
1. Mount it high. The 12v function of mine was knocked out by the water from a pile of wet clothes dumped beside it. For some strange reason the 110v function survived. I then removed a cushion from the settee and tied it down there with a little string and had no more trouble.
2. The lid is not very well insulated. You will need to supplement it with the soft cover that comes as an option.
3. Filling the unit with room temperature food and trying to freeze it only works if you have an inverter. It would probably take about 5-6 hours turned up to max cold and using 110/220. 12v would take 2 days. Once the food is frozen 12v can keep it there.
I still agree with the basic idea of a portable fridge/freezer for any boat that doesn't have one built in. It would also work well on a smaller boat or so with no fridge. Cool everything down (or freeze it) at home and then plug
in to a cigarette lighter adapter on board. That would work just fine for a long weekend aboard and not drain too much power.
Were I to buy a new one it would be the Isotherm
TB50 because I don't think the Waeco is well enough insulated. When set to freeze, the outside of mine was often wet and cold. OK, for just cooling
