While cruising through Wal-Mart this evening, I saw a couple of those 12
volt electric coolers designed for use in a car and I started wondering
if anyone has used one in your plane? If so, how good/bad did it work?
Any issues with the plane's electrical system? Was it worth not
having to deal with ice?

I've used one in a car before and not been real impressed with the
cooling capacity.
