A truck fridge needs to do the tough job of keeping food and drinks cool while enduring hours of over-the-road (OTR) travel.  A truck fridge may have to suffer through hot temperatures, cold temperatures, heavy vibration, jolting from potholes, unstable DC power, and a host of other challenges that truckers face.  A truck fridge is different from a car fridge that may not have to hold as much food and may be better suited to a thermoelectric model.

Long haul truckers don’t need the added inconvenience of stocking a cooler with ice or the pain of dealing with a thermoelectric cooler that just won’t keep their drinks and food cold enough.

Thermoelectric coolers depend on ambient temperature to achieve cooling, so if it gets warmer in your truck, particularly during stops, you may find your food and beverages getting too warm.  While a 12 volt cooler is portable, they are usually smaller because typical thermoelectric cooling devices do better cooling smaller spaces.

Do you need your refrigerator to be portable?  Most all portable, compressor-based refrigerators can be moved from place to place, but some are more portable than others.  If you’re going to be moving it yourself from vehicle to vehicle, then you should consider a portable fridge.

Some models can be either a portable freezer or refrigerator depending on your needs.

You may have an onboard inverter that can provide power to a regular refrigerator, but many portable refrigerators can handle either 12VDC or 120VAC power.  A 12 volt refrigerator gives you the flexibility to operate from an available 12VDC power port.






Portable, compressor-based truck refrigerators aren’t cheap.  You can expect to pay well over $500 for the larger sizes.  Many truckers feel that for the convenience and performance, you can’t beat a compressor-based portable truck fridge.

We searched trucker forums, manufacturer sites, consumer sites, retail sites, customer review sites, and social media to find the most popular and highly rated slim fit truck refrigerator.

Take a look at our choice and see if this is the best portable refrigerator for your needs!
