I dislike conversions myself, even went out of the way to find a TV and
DVD player that used a "brick" to convert 120 VAC to 12 VDC to power them, threw the brick away, wired them direct and took a chance that they would live on varying voltages between 12 and 14.3 VDC, they have been fine, even worked at 15.1 during
equalization, which was a foolish risk.
All 12 VDC icemakers I have seen are terribly expensive, as it seems most 12 VDC
appliances are, by an unbelievable factor of sometimes as high as 10, so to save the $ I gave up and use 120 VAC
appliances and accept the conversion loss. (its only about 10%, I think?)
As has been said, from an energy
consumption standpoint, you would likely be better off with an Engel, in fact I am sure you would be. But have you priced an Engle? Expensive ice maker.
Best way to use the table top ice maker, is to make ice when you have an excess amount of power, when motoring or running a
generator, bag the ice in 1 gl zip lock
freezer bags and put it in the
freezer.
The longer it runs, the faster it makes ice. The way it works is the ice it makes dumps into a basket, and as it melts the melt
water drains back into the reservoir which of course means you end up with pretty cold
water in the reservoir, you can make more ice from cold water than warm water of course, so after about a half an hour it really starts making ice pretty fast, then you refill it with warm water and the cycle repeats.
I have not tried starting with chilled water from the fridge, but bet that would help a lot
