Best 12 Volt Car Coolers for Travel, Tailgates & Camp 2020

What Are 12V Coolers Used For?

There are two kinds of 12 volt appliances for keeping your food or drinks cold in a car, van, or truck. 12V coolers and 12V refrigerators. The biggest difference between them is that coolers are only meant to keep things “cool” and portable refrigerators are meant to keep things “cold.”

If you buy a 12 volt car cooler expecting it to keep food safe temperatures all the time then you will be disappointed. 12 volt coolers are only meant to keep drinks and food cool and the inner temperatures depend on the outer temperatures. If you are planning on bringing temperature-sensitive foods on your camping or road trip you may want to consider getting a portable 12 volt refrigerator instead.

What are 12V coolers used for? They are used to keep drinks and food cool, if it’s not hot outside they will sometimes even be at fridge safe temperatures. What makes electric coolers so awesome is they don’t require any ice. In fact, using ice in an electric or 12 volt cooler is normally not recommended. This makes them perfect for tailgates and keeping drinks cool when camping or at parties.

Foods that aren’t sensitive to temperature can be stored in 12 volt coolers on road trips and are great for taking frozen food home from the grocery store. 12 volt coolers are much more budget-friendly than 12 volt refrigerators and if a cooler sounds right for you then you are in the right place.

Here are some of the best 12 volt car coolers on the market today.

Knox makes one of the best 12 volt coolers that also doubles as a 12 volt food warmer as well. No more showing up to the party with a cold appitizer, you can keep things up to 130 degrees Fahrenheit as long as it’s plugged into your vehicle.

The cooler itself is 27 quart. The inner compartment is 12.5 inches tall, 12 inches wide, and 8.5 inches deep. That means it’s tall enough to store a 2 liter bottle of soda.

The cooling feature can get down to 40 degrees when it’s around 70 degrees in the vehicle. That’s about 30 degrees below ambient temperature. If you have food that needs to stay at fridge safe temperatures (40 degrees) don’t let the car get hot.

The Knox cools or warms continuously. If your car is running while it’s plugged in you don’t have to worry about the power being drained. If you turn off your can the cooling feature will draw around 40 watts and the warming feature will draw around 48 watts. It’s a small number but can drain a car battery and damage it fairly quickly when it’s not being charged. Make sure you don’t leave it plugged into a vehicle that isn’t running for too long.

The 12 volt cooler comes with a DC cable that is 5.5 feet long that has it’s own storage compartment in the lid. The handle doubles as a locking mechanism so you can be sure the lid is on tightly making it as efficient as possible. Make sure the air vent is in an open spot allowing the car cooler to get enough air.

The Knox Electirc Cooler and Warmer is a great little car cooler with a slim design to fit easily behind a seat or on the floor in front of one. You can keep food at fridge safe temperatures if you keep the car at 70 degrees which is perfect for bringing cold food home from the store. It’s great for picnics or keeping drinks cold while camping or tailgating. All-in-all it’s a fantastic 12V cooler that will save you from having to buy ice.

The Knox is a well built electric car cooler that will not only keep your food cold or warm it will do it for years to come. It has a slim design which fits well in vehicles and there’s a compartment for the power cables so you don’t have it laying in a messy tangles mess when it isn’t in use.

12 Volt Cooler

Things to Consider

Vehicle Space

Most of the 12v coolers on this list have the air vents in the lid so you can easily slide it between stuff without restricting airflow. If you have an electric cooler with the air vents on the side like the Coleman 12V Electric Cooler make sure it has plenty of space on the side with the motor so the cooler doesn’t get damaged.

Vehicle Temperature

Your vehicle can get hot very quickly especially when it’s sitting in the sun. Even if you are only going to be away for a few hours and the cooler is plugged into a power source it may not have the capacity to keep your food the temperature it needs to be.

40 degrees below ambient temperature is the coldest these coolers can get, which means once it gets to 90 degrees Fahrenheit in the vehicle the food in the cooler is sitting at 50 degrees which is an unsafe temperature for sensitive foods.

If you need something that can hold 40 degrees and below even when it’s hot consider getting a portable 12 volt refrigerator instead.

12 volt car coolers are great for road trips and camping

Vehicle Battery

12 volt coolers are simple machines designed to cool your drinks and snacks while you drive. Sometimes you may need to turn off your car and leave the cooler plugged into the battery. That’s fine for a little while but the cooler can slowly drain your battery and you may be left with a dead one by the time you get back. Electric coolers run constantly and even just 40 watts being drained constantly will drain a battery fast.
