These Coolmatic Waeco coolers are built with the Danfoss BD35F
compressor from Denmark, which means they run extremely efficiently on 12/24Vor AC power.
The 28 gallon model above consumes only 65 watts on average (45 watts on 12V DC). You can get an insulating protective cover to make them even more efficient.
The coolers also have a control panel where you can set the exact cooling
temperature you desire.
This means the food contained within them can be kept icy cold for two days straight on a single 80aH battery.
