The Most Recommended Thermoelectric Coolers: 5 Best Thermoelectric Cooler Reviews By Sujana Marie
We’ve pulled together some of the most popular coolers on the market and provided in-depth reviews so you can find the one that fits your busy life.
1) Koolatron Compact Thermoelectric Cooler Review
If you have been looking for a cooler to fit behind the seat in your truck, the Koolatron will be the best thermoelectric cooler for you!
It is a little smaller than the other units we have looked at, and it’s more expensive, but it is only 9 inches wide with an easy tilt lid.
Leave it in the truck, flip the seat forward and grab your nice cold lunch!
Or flip the switch and your leftovers will be kept warm all morning until break time.
It is extra deep, so if you don’t have long arms you may be struggling to pull snacks out of the bottom, but you will never have it tipping over while riding in the passenger side footwell – or causing your guest to struggle to sit comfortably while accommodating an oversized cooler.
Just double check that you have the switch set to the right setting before taking off for the day and avoid being disappointed with a nice hot soda when you wanted a cold drink.

- Heats and cools
- Easy to use flip up lid

Now, it has a rating of 36F–which according to the manual means that it will cool the contents down to 36 degrees below the outside air.

For the family on the run, the Causalyg offers fashionable looks on top of its functionality.
It features a double-insulated zipper that closes up the roomy interior, making it the best thermoelectric cooler for those who wish to carry their unit out to the park for a picnic.
It does double between a cooler and warmer with the flip of a switch, but there are no controls to adjust the temperature settings.
The unit arrives with the standard 12-volt connector ready to plug into your car’s auxiliary port, and an adaptor can be purchased separately if you want to be able to bring it inside at night.
It is priced slightly higher than other units, but with its sport-bag appearance, you might expect that.
However, when you add on the highly-priced power adapter, it becomes overpriced.
Users report it works as intended, so a good buy for a family that wants their gear to match their wardrobe.

It is only a cooler, not a warmer/cooler. Like the others, it runs on 12 volts, but an adapter can be purchased so it can be plugged into standard outlets as well.
Rated to cool up to 40 degrees below the outside temperature, it offers more chilling power than the competition.
Now, its modular design allows you to open the lid from the left or right when it is placed on its side, or use it as a chest cooler while riding in the back of your SUV.
It offers a nice low price for the extra room and versatility when compared to other units on the market.

- Not a warmer/cooler
