Best Overall

1. Koolatron Compact Thermoelectric Cooler

Koolatron Compact Thermoelectric Cooler

What You’ll Love: 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.

Pros:

  • Slim and tall design fits behind truck seats
  • Heats and cools
  • Easy to use flip up lid

Cons:

  • Hard to read switch
  • More expensive
  • May overheat 12-volt outlet

2. Igloo 28 Quart Iceless Thermoelectric Portable Ice Cooler

What You’ll Love: This is a simple unit and sized just right to fit a large picnic for the family, making it the best thermoelectric cooler for daytrippers.

The Igloo is only a cooler and runs on a simple on/off a motor. It comes with the 12-volt cord and connector to plug into your car.

If you want to plug it in inside the house, you will need to buy a separate adapter. It is competitively priced and fits nearly 2-cases of soda.

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.

So, if you are having a picnic on a 90F day, it is only going to chill your drinks down to 54F–which is not particularly cold. It is hard-sided and is designed to fit in the rear footwell of most vehicles.

Pros:

  • Simple, easy-to-use design–plug it in and it’s on
  • Holds up to 24 cans
  • Fits behind the seat of your car

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.

Pros:

  • Attractive designer exterior
  • Zippered closure for easy access anywhere

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.
