There are also Peltier effect coolers on the market. They will cool 20
degrees below ambient. If you load up cold and frozen stuff to start
with one of those can extend your keeping time. We had one on our
firts boat but we still used a ot of ice. A couple of inches more
insulation would also help.



Just gave my last one away. 4A of continuous drain, 24/7, to make hot Coke
just warm. Not even close....

If you put cold Cokes in them, they'll keep them nearly cold. If you put
warm Cokes in them, they might cool a six-pack in a month....(sigh)

Useless....
