Cheap Fridge Idea
My Koolatron cooler used 4Amps @ 12V, about the same as my Addler-Barbour "Cold Machine" compressor unit.
The Coolatron runs full time (4A x 24Hrs = 96 AH per day), and maintains < 40 degree differential twixt ambient & box. The Peltier unit failed after 2 summers of continuous use (dockside). Kooatron advised that cost of module was about same as cooler +/- $100.
The Addler-Barbour is still running fine after 10 years. My reefer box is NOT super insulated, so the compressor runs about 18 Hrs/day (Florida/Bahamas), utilizing about 75 AH/day. Cost of A-B unit c/w ''stat < $450.
In any case (whatever reefer installed) INSULATION is the key!
