It’s a mini fridge for your car. These work for far more than just your car; you can use this to transport a cold lunch to work, to bring with you to a buddy’s house on game day (most of these are designed to hold a six-pack of cans). You can basically use these anywhere, but the ones we’ve chosen are ideal for car use based on their durability and compact size. Most of the units we’ve selected will come with the necessary 12V adapter to use with your car.
Car coolers also serve another purpose: keeping food warm. Most models will be thermoelectric, and most of those come with a warming function as well. Warmers usually run to at least 140 F degrees, though some run in ranges of 120 F to 160 F or more. The reason for this is that food safe levels were 140 F pre-2013, and have recently been changed to 135 F. This keeps bacteria from growing on your food while it stays warm.
