Electric Cooler

If you like to spend most of your summer days outdoors, whether it's camping, fishing, hunting or barbecuing, it's time to pack all your gear. And no summer outdoor trip is complete without a traditional cooler or an electric cooler! There are many reasons to buy coolers, such as providing extra space for campers to store food while traveling. But the main purpose is to keep food and beverages cold (and warm depending on the model!) when not stored in a refrigerator. Even without the need for an ice bar, these electric coolers will keep your food cool for the duration of the getaway. Whether you're a first-time camper or want to use these as a second refrigerator at home, a cooler is a handy gadget to have.

However, if you're still using a conventional cooler, you know the hassle of filling it with ice bars, regularly checking to make sure your drinks are cool, and emptying the water at the end of the day. Not to mention checking for leaks if the model you're using isn't properly sealed or waterproof. After all, the last thing you want to do is clean up a soaked car.

But did you know that a thermoelectric cooler can save you all that hassle? They run on electricity, so all you have to do is plug it into a power outlet (AC or cigarette lighter). And there you go, you're ready to go. No ice and no worries about leaks. An electric cooler is a great solution for anyone who wants to have a worry-free summer. And they're especially great for long summer trips and outdoor activities. Plus, they're perfectly suited to act as a mini electric fridge for cars, trucks and boats.

How to choose your electric cooler?

Portable coolers and electric vehicle refrigerators can be the perfect addition to your camping gear or in cases where you don't have access to a refrigerator. But before you buy a thermoelectric cooler, there are several important factors to consider.

Portability and capacity

First, what size electric cooler are you looking for? If portability is the most important factor for you, check to see if the cooler has wheels or ergonomic handles. These features allow you to take your cooler with you from one destination to another, which is ideal for campers who want to walk a bit more.

Most importantly, keep in mind the size you're looking for based on the amount of drinks and food you'll be carrying. Do you need a large capacity or is a small compartment enough? The capacity will be a deciding factor in your choice and also in the purchase price. If you want to use the cooler as an additional refrigerator in your home, consider a model with at least 50 liters. This refrigeration capacity will accommodate about 80 cans. But bigger isn't always better. To keep the electric cooler at its optimal temperature and improve energy consumption, make sure it's full. Otherwise, it may not maintain a low temperature or it may consume more energy. Indeed, a cooler (this applies to rigid and flexible coolers, insulated bags and lunch boxes) that is filled to the maximum will efficiently maintain the temperature. Indeed, the less air there is, the better the thermal insulation is!

Conception, design and shape

The shape of the portable cooler is essential for organizing and storing everything you need for the vacations. If you want to take wine with you, opt for coolers that have a dedicated section for bottles. You can also opt for coolers with dividers to separate snacks from other foods.

Also, if you want to store large bottles of water on top, you will need a tall cooler to accommodate them. Finally, the length of the power cord should also be long enough so that you can charge the electric camping cooler while driving, without having to place it too close to you. The length of the power cord is often an overlooked detail, but is a must-have. At Healthy Lunch, we strive to bring you electric coolers that meet these practicality criteria.

Thermal Insulation

Look for options with sufficient thermal insulation that is lightweight and energy efficient. One of the best materials is polyurethane foam, which is what we use for all our electric and rigid cooler models. Having a powerful and efficient thermoelectric cooler is important, but having a well insulated model is even better. It will keep the temperature for 6 to 8 hours without having to plug it in. For this, a perfectly sealed model with a quality lid is essential.

Is an electric cooler better than a hard or soft cooler?

Electric coolers act as portable mini-fridges and can keep anything cool for an extended period of time. With 12V/24V/220V power consumption, they offer incredible performance that is ideal for road trips, provided you have the means to power it. However, if you add ice packs to the cooler, it can continue to insulate whatever is inside without power consumption, acting like a normal hard cooler.

On the other hand, electric coolers can sometimes make your food too cold. You also can't change the temperature of each item inside, placing some snacks on top to make them cooler than those below. Also, because of their power, these compressor coolers can be heavy, making them difficult to transport. So we recommend that you choose the right model for your needs. At Healthy Lunch, most of our models have an LED remote control so you can easily manage the temperature in the interior compartment of your cooler.

Generally speaking, electric coolers are the best options for keeping food and drinks cool, thanks to their better insulation. Although insulated bags don't offer the same cooling performance, they don't require AC power or charging to operate. Because of their design, cooler bags are also much lighter than coolers. In addition, you can fold the item when it is empty, making it ideal for limited storage space.

So you'll need to choose between an insulated bag and a cooler depending on your storage goals and getaway plans.

How do electric coolers work?

So how does an electric cooler work? Electric coolers use the Peltier effect as their cooling method. Simply put, when you pass an electric current between two different electrical conductors, such as zinc, copper or aluminum, you can create a temperature difference, which is a cooling and/or heating effect. As the current flows, heat moves from one side to the other, making one side warmer and the other colder.

The technology known as the "Peltier effect" is placed on the lid of the cooler so that it does not come into contact with food and beverages. Combined with a ventilation system, it transfers heat from the inside of the cooler to the outside to keep drinks and food cooler for longer.

In addition, many portable electric coolers are powered by a 12V port for your car (also 24V for a truck), or by a traditional 220 outlet for use at home or camping.

So there you have it, an electric cooler is very simple to operate and very useful. This little bit of science can help you keep a thermoelectric cooler running reliably so you don't have to worry about ice.

How to use an electric cooler?

Unlike the classic rigid or flexible cooler, using a thermoelectric cooler is quite simple. All it needs is a power supply. So you can easily plug it into your car's cigarette lighter, sit back and forget about it. Also, most models offer standard 220V power outlets. This allows you to plug it in anywhere. For example, if you are on vacation and sleeping in a hotel, during your night you will only need to plug the electric cooler into an outlet.


In addition, there are some models that have a built-in battery and can operate anywhere and anytime. However, these rechargeable electric coolers will have a higher price tag than other models.

Ease of use is the reason why thermoelectric coolers have become so popular for outdoor activities. Since they are completely ice-free (no need to add ice packs inside), they guarantee you worry-free outdoor time with your friends and family. You don't have to worry about searching for ice or even having melted ice seep into your food. Best of all, no ice means no water leaks. So your car's interior is not at risk of getting soaked by a cooler that is not properly sealed and waterproof. That's why electric coolers have become a popular choice for cars, trucks, boats and campers, even on long trips.

They are also perfect for indoor use and are a convenient alternative to the portable refrigerator. And since there are no leaks, there's no soaking mats or cleaning to do. This makes these models perfect for your bedroom or even a trailer.

How long do electric coolers stay cold?

Rigid coolers typically stay cold for up to three days, with better models staying cooler for longer. However, electric coolers can stay cool as long as they are plugged in. If you don't have access to a power source during your trip, you may need to consider other options.

When planning your camping trip, you should also consider the time of year you will be traveling, not just the length of your trip. For example, if you are at a campground for several days in the summer, a compressor cooler can freeze snacks if you need them. However, it will require more energy to operate. But for a week-long trip, an absorption cooler may be a more energy-efficient option. It may not be the most powerful type of cooler, but you can place ice packs in the refrigerator component to keep the contents cool.

Finally, a thermoelectric refrigerator requires your food, meals and lunches to be fresh before you go on a camping vacation.

At what temperature does an electric cooler work?

The Peltier plate inside a thermoelectric cooler can be up to four degrees Celsius cooler than the ambient temperature. Compared to home and camping refrigerators, coolers are capable of differential cooling, which means that the warmer it is outside, the colder it is inside. This makes the unit ideal for keeping snacks and drinks cool in the summer.

Can you refrigerate and freeze at the same time?

Fortunately, many products have a freeze and chill mode and two independent temperature zones. This means you can keep multiple items at their ideal temperature in the same box.

So you don't need to plug in two different coolers and you can keep your ice cream and bacon in the same cooler box.

How do you plug an electric cooler into a car or truck?

An essential accessory for long trips, the electric vehicle cooler allows you to keep your food and drinks both cool and warm at all times, depending on the model. Most models of electric car and truck coolers plug into a cigarette lighter and are compatible with 12 and 24 volts.

How to connect a 12V/24V electric cooler?

12V/24V electric coolers or refrigerators are an innovation that combines state-of-the-art equipment with consumer needs. They are sophisticated versions of standard rigid coolers. Designed for travel, this car cooler fits in your vehicle to keep your perishables from spinning during your trip. The biggest advantage (and what really makes the difference with a regular cooler) is that not only will the electric car and truck cooler keep your drinks cold, but there are some that will keep your food hot. At Healthy Lunch in particular, you can find in our collection high performance electric coolers that are reversible, ensuring that you keep your meals hot as well as cool.

The idea behind the electric vehicle coolers was to create a smaller version of the traditional kitchen refrigerator for spaces that don't necessarily have room for this type of compressor. With a 12V cooler, the only moving part is the small fan. The component that powers the product is no larger than a matchbox and is designed to keep your items as cold as if they were sitting on a 5kg block of ice.

How does an electric car/truck cooler work?

Wondering how a thermoelectric cooler works? 12V/24V electric portable coolers work like a regular refrigerator to keep food cold and edible for long periods of time. These electric car coolers can save you time and money. For example, if your family is taking a vacation, instead of stopping at fast food joints or restaurants every day, you can fill the thermoelectric cooler with sandwiches, juices, fruit, vegetables and chicken. You can even put in a takeout for a party or dinner. Plus, for electric heated coolers, you'll be able to prepare tasty meals in advance and enjoy them anytime.

What are the different types of cooling technologies?

There are three different types of technology: electric plug-in coolers, compressor coolers and gas coolers.

Not all portable coolers offer the same experience, as they use different technologies. A thermoelectric cooler is lightweight, runs on 12/24 volts, maintains room temperature and uses cooling power that prevents mold growth.

On the other hand, the technology used in compressor refrigerators is powerful and can even preserve frozen food. In addition, it operates at low power and performs well in a variety of environments. Many compressor coolers using this technology are also suitable for solar operation and have built-in battery protection.

Finally, gas refrigeration technology allows you to keep snacks cool when traveling off the grid. They are quiet, making them one of the best products for quieter areas or places where people are sleeping. They are also available in a 3-way power option and gas operation.

If you are in the market for a camping refrigerator, you may want to consider an electric cooler. There are several options to choose from. But whatever your requirements, they keep the air cool inside to keep your drinks and snacks fresh.
