Description

12 volt cooler refrigerator car use the same type of refrigeration equipment as is found in standard home refrigerator freezers. A portable refrigerator is cooled using refrigerant gas, a refrigeration pump, a condenser and coils. The main difference is that the 12-volt refrigerators are built in such a way that they do not need to be perfectly level to operate properly. Another great difference is in power consumption. The refrigeration pump runs on very little power, and the insulation in the refrigerator door and walls are of high value.
All of the DC powered portable refrigerator freezers are thermostat controlled. Some have a dial thermostat control and others use a digital thermostat. The chest style 12-volt refrigerators and freezers by Engel and Summit Appliance are also capable of deep freezing, making them perfect for EMS and field researchers.
What is the typical lifespan of a 12 volt refrigerator? Generally we see refrigerators by Dometic Waeco, Summit Appliance and Engel working well even after five or ten years. That's not to say that they'll all last that long, and in some instances they may last longer. This all really depends on how well they're taken care of and the environments which they are used in.
So why wouldn't you want to use a normal home refrigerator freezer with a power inverter in your truck, RV or off-the-grid application? Because it's not a good idea! Firstly, because this method creates yet another point of possible failure. When run too hard a power inverter will fail. Aside from that, power inverters are typically very inefficient. This means that the power inverter will consume a lot of DC power just to create a little 110v AC power.
