Free for shipping. I bought this from Pep Boys years ago thinking it would work for off-grid. Unfortunately, Peltier junction cool boxes use lots of power and don't cool all that well.
I let the guys in the warehouse use it to keep their sandwiches cool. The 120v switching power supply finally quit so they gave it back.
It can be run directly from 12vdc. I'll include the burned out 120v converter.
It doesn't weigh much and is about 18" x 15" x 15" The wiring diagram is taped to the top.
