I ordered the Alpicool C20 for $239.

Let me know the startup and running current draws when you received
it. Very curious here. I've never seen a 12/24vdc compressor.

The compressor draws about 30W, 2.2A at 14VDC. With the compressor off
the controls use less than 1W.

I cooled it to -20C and then connected a DC power meter and ran it 61
minutes (to shutoff), using 1.172 Amp-hours at 13.8V, or 16.1
Watt-hours, in my 56F basement. At that rate a 12V 105A-h battery
should last 2-3 days.

The cold plate is behind one wall of the food compartment, without a
circulating fan. I'll have to experiment to find the right packing
arrangement and temperature setting for frozen food. -20C is its
lowest.
