See my other post. Wayne's "cooler" isn't a Peltier chip and heat
sink, it's an actual refrigeration unit with a compressor and
everything. The real deal, just miniturized and very efficient.
Those "chip and heat sink units" you're talking about are about $100.- Hide quoted text -

The Peltier chip units have never gotten very good reports, They have
trouble keeping things cool when ambient temperatures are greater than
75 to 80 degrees. The Engels on the other hand will keep things at
zero degrees when sitting in tropical sunlight and they draw less than
5 amps of power at 12 volts. I first heard about them from a guy who
has been living aboard for many years.

Another alternative, much less expensive, is to buy a college dorm
type fridge at one of the big box stores and run it from a small
inverter. They are typically less than $150 and small inverters are
in the $30 to $40 range.


Why are these a better solution than a Yeti ice chest?

An ice chest needs a constant supply of fresh ice. A small electric
fridge does not, and some will actually make ice.
