By applying a voltage across the joined conductors, an electrical current is created. This current flows through the junctions of the conductors and this allows heat to be removed from one and deposited on another. The best cooler will lgloo Cooler be a compromise between cost and cooling effectiveness. If you must have truly ice-cold drinks that stay ice-cold for hours even with the cooler shut off, you’ll need to invest in an expensive DC cooler like the Dometic CFX3 45.
If there is an outlet, there is an ice-less way to keep your food cool. Whatever your next trip has in store, these plug-in coolers are ready for the journey. Thermoelectric coolers will chill your drinks or help keep your lunch cold while your AC is on while you’re driving, but they need a constant supply of power. That’s a pretty big detriment for anyone hoping to achieve USDA food-safe temperatures if it’s warmer than 76º F outside. That fairly major flaw notwithstanding, the Igloo does have a decently large capacity of 60 cans — and beers or sodas don’t need to be 40º F.
In balance, the Coleman Powerchill offers a good value for your money, with decent performance and relatively large capacity. The only real things to worry about are its higher power draw and louder fan. You can open up this cooler from the right or the left when in upright mode. If you’ve got a very compact space, like in a tiny house, this offers a lot of flexibility in where you put it.

There is a helpful touchscreen interface with a companion smartphone app. One of the biggest setbacks to most electric coolers is that when they are not in use, they take up a lot of space. Like conventional soft coolers, the Koolatron D25 can pack up small, which is great for a road trip or off-season storage. Incredibly, it operates as both a cooler and a warmer from as low as 40 degrees to as high as 135 degrees. Its soft design is not without creature comforts as it has exterior pockets and cupholders.
