How Do 12-Volt Coolers Work?
The function of a 12-volt cooler is no different from a normal refrigerator you would use in your home. Basically, these units can serve as a mini fridge you can use on the go. Put in drinks or food items and they will be kept cool by a complex principle known as the Peltier effect.
How to Choose a New 12V Cooler
Choosing a new 12-volt cooler may not be a hard task if you know the right features to consider. Just look at the right aspects, pick one for yourself, and rest assured, it will be the right one for you.
Before you get a new unit, you need to take into consideration how much you will actually be putting in there. Spending extra on a model with greater capacity is useless if you don’t plan on storing much in there. So always remember the capacity you will need for yourself.
Since these units are connected to a power outlet, it is important to consider how efficiently these units consume electricity. If they aren’t good at that, you may end up paying more in electricity bills than you would for the unit itself.
Portability is a very important factor, as these units are mostly used outdoors. Consider a lightweight unit that is easy to move around. If not, you may be stuck with a constant ache from carrying the unit around.
This is obviously an optional feature, but if you are someone keen on keeping different types of items separate, it may be a key feature. A divided compartment can help you separate food and drinks, or different types of foods.
Benefits of Investing in a Quality Model From Our List
The final question that stands is, why should you choose from this list? Sure, the options are plenty, but this list provides you with a couple of advantages that may serve to be the reason why you choose a certain item.

The list not only reviews the best products but also provides you with a complete product outline that guides you through their main features. So, when choosing from this list, you will know exactly what features you will be getting from a product.
Are All 12 Volt Coolers The Same?
If you’re thinking of buying a 12V cooler for yourself, you need to know what to look for. Not only are there different brands and different models available on the market, but there are also different types to choose from. Some common types include:
These coolers are very effective in keeping things cold while you’re on the move. A thermoelectric cooler can cool down items to at least 30 degrees below the surrounding temperature. With such units, you do not require any ice, so there’s less mess. These units are easy to use, and they feature a small, compact design that allows you to save space in your vehicle.
Such coolers use the Peltier effect, a low voltage passes through the plug in the cigarette lighter, then through the first conductor, which is then deposited at the second conductor. All the heat is removed before it gets deposited, which helps in creating a cooling effect. The hot air gets blown off by a fan, and the cooler is able to reach its target temperature.
These coolers are more suitable for people who either live in colder regions or are planning on going there since they cannot keep your food frozen.
These types of coolers feature a system where the refrigerant liquid is evaporated and turned into gas while extracting and releasing heat. They make use of the same technology that is used for domestic fridge/ freezers.
They provide you with efficient cooling and are capable of deep freezing, unlike thermoelectric coolers.
These types of coolers are mainly used in RVs, they work with both electricity and propane. Compared to the other two types previously discussed, absorption fridges require a lot of power in order to function and can end up draining your battery easily. Similar to thermoelectric coolers, these fridges are dependent on your surrounding temperatures and can only go about 30 degrees below it.
Safety Considerations for 12 Volt Coolers
When buying 12 Volt Coolers, you need to know how to look after them to ensure safety. It is essential that you don't do something that could damage your unit and cause you or your vehicle any harm. A few things that you need to be aware of are:
You need to make sure that your cooler is well-insulated and that the temperature inside the cooling system does not drop too fast while you’re opening and closing the lid. There will be a slight drop in the temperature, however, if you notice a drastic drop, then that could be a red flag, indicating that there is some sort of issue with the insulation.
If your cooling system has good insulation, it will keep its internal temperature even when it is exposed to direct sunlight and heat. However, if you want to reduce this drop in temperature, especially when you’re out in the heat, make sure to use extra insulation covers.
No one wants their vehicle to smell like rotten food. Therefore, to avoid stains and odor, you must clean your units after using them. Understand that if you own a sidelined fridge and do not clean it, then it will start to smell bad, and you’ll also be exposed to a number of harmful bacteria.
Limit Opening the Lid
While opening the cooler repeatedly to take out cool drinks seems ideal, this causes the food and drinks inside the cooler to get warm as the cool air escapes. In order to keep your cooler running optimally and to keep the battery usage low, you need to limit the number of times you open the lid.
See that you leave some space around your cooler so that the vents are not blocked while they run. Understand that your cooler is dependent on its surrounding temperature, therefore, the unit needs to breathe to function properly. So, when setting your cooler, make sure that you keep it in a well-ventilated place so that it works efficiently.
Both sun exposure and high heat will affect the performance of your 12-volt cooler. Therefore, it is important to keep your cooler in a shaded area, away from the heat. The best part about having a portable 12-volt cooler is that you can easily move it around. Also, if the inside of your vehicle get really hot, turn on the air conditioning, otherwise, the cooler’s cooling system can get damaged.
How to Hook a 12 Volt Cooler Up to a Battery
There are different ways you can power up your cooler. Here, we have mentioned a few different ways of doing so. You can go through them to see what you’re supposed to do and how you should do it.
The first option is to run the cooler off your start battery. Sometimes, you can simply plug the cooler into one of the factory cigarette sockets present on your vehicle.
The other option is to run a separate wire down to a different cigarette socket. Factory wires are often too small, and your cooler can cut out really early because the voltage will drop every now and then, and the current running down the wiring will be too little, causing the cooler to cut out.
With the cooler running off the cigarette socket of the start battery, you will have two options. You can run it off the battery, however, this can kill your battery, and your vehicle won’t be able to start.
The other option is to put it to an ignition feed. This means that the cooler will only be provided power as long as the ignition is on. As a result, you won’t be using a start battery, instead, the alternator will be chargingthe cooler. With this method, the cooler will only run as long as the car runs, which means all the things in the cooler will eventually get warm if your vehicle is off.
You can also connect the cooler to the battery feed of your start battery. This way, your cooler will always have power. Attach a low voltage cut out and set it up to 12 volts. Once the battery voltage reaches your selected voltage amount, it will cut power to the cooler. This way, your vehicle will be the first thing to start, however, your cooler will cut out fairly early.
In case you’re still confused, we have attached a video below for you to see and understand what to do and how to do it. Hopefully, it’ll resolve all your queries.
When Would a 12 Volt Cooler Come in Handy?
These small, portable units are a blessing in disguise for all those who spend the majority of their time on the road. When you’re in dire need of cold water, but there is no shop or gas station nearby where you can buy one from, that is when these units come in handy the most. You would most definitely need a 12-volt cooler in the following cases:
To Keep Food Warm/Cold
If you’re going on a road trip, you will need a place to store your food and keep it cool the entire time, these 12-volt coolers will definitely do that. However, if you want warm food, that can also be arranged, some special 12-volt coolers can warm your food as well.
Take Your Food on the Go
In case you are no longer traveling in your vehicle and are walking to your next destination, then you can take your cooler with you. 12V coolers are portable and usually battery-powered, so you can take them with you as you go. They will keep your food cool for hours even after you have unplugged them from the power supply. And since they are so lightweight, you can easily carry them around without any difficulty.
Charging Your Phones and Other Devices
Some 12-volt coolers feature USB ports that allow you to charge your phones, laptops, tablets, and other devices while cooling your food and drinks. And since these coolers are so small, they don’t require a lot of space, so you can easily do both the things simultaneously without taking up too much space.
Forget the hassle of using ice in your coolers. Pick a 12-volt cooler from this list and make your life considerably easier. Keep your food and drinks chilled or hot, and enjoy your picnics, camping trips, or even long drives. Just ensure that you’re looking for all the right features.
People Also Ask
If you’re thinking of buying an electric cooler for yourself, make sure to keep all the things mentioned above in mind. However, the market is filled with 12V coolers, so if you're still confused about them, go through the following section. We have answered some of the most common queries that people have below:
How Does a Thermoelectric Cooler Work?
Thermoelectric coolers are a good option for you to consider. They use the Peltier effect, the voltage passes through a joint conductor and helps create a current. Once it reaches one of the conductors, the heat being released from this current is then removed from the electric junctions. As the current gets deposited at the second junction, there’s a difference in temperature.
Is a Portable Electric Cooler Worth it?
Portable electrical coolers are usually designed for truck owners and daily commuters who are always out on the road driving and basically need a place to store their groceries and drinks to keep them cold. So, if you’re on the road daily and have a constant energy supply, which is your engine, then these coolers are a good option. However, if you don't constantly drive and don’t really feel the need to cool your drinks, it is better to opt for a simple ice chest.
Are Electric Coolers Safe?
Most 12-volt refrigerators are considered to be safe as they can withstand rain showers and splashes, which makes them a secure option, however, you do want to prevent them from submerging in water. Meanwhile, most thermoelectric coolers are normally safe. However, when using them, you should avoid placing ice cubes in them just to be on the safe side.
How Cold Does a 12-Volt Cooler Get?
If you opt for a cooler from a reputable brand that features high-quality construction, then it will deliver temperatures that are up to 30 degrees lower than the temperature of your surroundings. Generally, how cold your cooler gets is mainly dependent on the ambient temperature.
How Long Does it Take For a 12-Volt Cooler to Get Cold?
This mostly depends on your cooler’s internal capacity, as well as the temperature outside, generally, it could take up to an hour. A more efficient method would be to plug your cooler in while you’re at home and pre-chill it before you install it in your vehicle. It is also recommended that you pre-chill your food and your drinks before you load them into the cooler so that when you consume them, they’re extremely cold.
How Long Can a 12-Volt Cooler Stay Cold When Unplugged?
A good-quality portable cooler is properly insulated to prevent the cold air from escaping when the unit is unplugged. Just make sure that the cooler is sealed properly and that you don’t open the lid unnecessarily, this will help keep your food and drinks cold for hours.
Will a 12-Volt Cooler Drain My Battery?
Your cooler will not drain the vehicle’s battery when the vehicle is running. However, it is important that you take precautions. Avoid plugging your cooler in when the vehicle is not in use and is parked. You can even opt for a battery saver to ensure that your cooler switches off automatically when the battery’s power drops and is less than 11 volts.
