Dometic CF18 12v Electric Powered Cooler, Fridge Freezer – Best Electric Ice Chest Freezer

Coming in at a sturdy 29.6 pounds, and measuring in at 18.4 x 29.6 x 19.4 inches is the Dometic Portable Freezer/Refrigerator (available at Amazon right here). You can go small at 10.5 liters or go big at 106 liters.

Wait, what? Yes, you read correctly. We ARE reviewing electric coolers, and though this is a portable freezer and refrigerator, this one STILL fits the bill and falls under this category.

One user called this unit “life-changing.” The user is a truck driver who often kept a microwave and DC powered cooler in his truck. While it allowed him to save some money by avoiding eating at truck stops, picking up the Dometic changed his life completely. In the past, his menus were limited but since he now has a freezer on the go it has changed his life.

Is this the best electric cooler then? Well, we think it's a real jewel and one of the top iceless coolers for sure.

K-box Wheeled Electric Cooler & Warmer

The K-box cooler isn’t merely a cooler – it can also work as a warmer! You change between the modes via the switch situated on the lid. Not everybody will need this function, but for some people, it will be very nice to have.

This cooler runs on either 110V household current or 12V DC power. K-box provides cables & plugs for both types of current, so you don’t need to buy them yourself. Besides, you can use the 12V DC cable to power the cooler from your car’s cigarette port.

The K-box cooler is sized pretty decently – its capacity is 48 quarts. And given that you don’t have to put any ice in, you get way more storage space from this cooler than with traditional ice coolers of the same size.

This cooler also has integrated wheels, but they are small and not the best for off-road conditions. They’ll work effectively on only flat surfaces.

In terms of temperatures, the K-box cooler maintains 40 degrees Fahrenheit – pretty typical for refrigeration. However, note that this won’t be enough for some food items – before packing, be sure that you are taking food items that won’t spoil under 40 degrees.

One user, in particular, seemed to get their money’s worth from this cooler taking it on a 4,000-mile summer trip that took them through 7 states and back. The user stated that it fit perfectly in the car and worked as advertised AND that all of the food stayed fresh.

  1. nothing comparing the quality.
    i have burnef through 4 coleman’s in less than 2 years.
    their average life span in 2 months, if you are lucky, before the motors burns out.
    Coleman should be ashamed of themselves for selling such a horrible product.
