Boat Portable Refrigeration
I''ll pass on the ''what you should do'' stuff and try to answer your question. A good friend is currently using an Engel (the larger unit) as an on-board freezer while living aboard in (currently hot/humid) Florida. The boat is air-conditioned so it''s operating at about 80-85 degree ambient. He sets it about midway on the 1-5 thermostat setting, where it freezes ice cream rock solid - which was the motivation for his purchase in the first place.
He measured it at 2.7 amps DC (while plugged in, so that''s a full/healthy 13+V of DC) with a duty cycle of roughly 60% (his estimate).
Seems to be a great way to expand refrigeration capacity at the dock or while doing an ICW cruise (lots of motoring = lots of amps for hard ice cream), and it''s cheaper & easier than buying/installing a built-in system. The whole thing turns upside down once you leave for the Bahamas, of course - where it will ask roughly 75 amp/hrs from you, day in & day out, beyond all your other 12V consumption. Unless you have a very unusual 26'' boat, that just won''t be practical. But hey, unplug it and do without...and then enjoy the treats when you return to the dock. It''s not like you can''t enjoy it when its use makes sense.
