Coolbox buying guide

Temperature Maintenance

Your selected cool box needs to be able to maintain a consistent temperature to ensure that your food doesn’t spoil. There’s no use keeping fresh milk in the fridge if the temperature gets too high, which causes it to go bad. Higher quality cool boxes will be better at maintaining a consistent temperature.


For days out away from your caravan, you’ll want to load up your cool box with items and take them with you, but this is not ideal if your cool box is difficult to carry. Ensure that your desired cool box has side handles which makes it more convenient and easier to carry. You should also check if it’s made from light materials, so it doesn’t add too much weight on top of the contents weight.


Discover the size of your chosen cool to understand if it will fit your needs. If you have a large family, then you’ll likely have more food and drink than a couple so a bigger cool box will be better suited. 

The size is also important because you need to know if it will fit into your caravan without being a hazard or block any walkways. 

Power Source

It’s important to understand the required power source of your cool box to ensure that you have the necessary power source to run it. Some units will be more versatile than other and have the ability to connect into multiple sources of power including your vehicles cigarette lighter. By finding out the required power source, this will remove any surprises when it’s time for you to use it.


Throughout the day the noise of your cool box isn’t likely to bother you, but throughout the night the cool box will still be on, and this can disturb you especially if it’s close to your bed or you’re a light sleeper. Electric cool boxes are often powered by a fan which can produce a noticeable amount of noise. However, some models have quiet modes which will lower the amount of noise emitted. The more eco-friendly and energy-efficient models will often be less loud.


The best cool boxes will be made by some recognisable household brands that have established themselves due to their high-quality products. The higher the quality of the brand you can usually expect there will be better features and benefits; however, this will also be reflected in a higher selling price.


A warranty is also linked to the quality of the brand where a better brand will likely include a warranty which entitles you to a replacement or repair if your unit develops a fault or stops working completely. The length of the warranty varies in length from 30 days to lifetime, so be sure to check this before buying.

Easy Clean

You need to treat this how you would treat a fridge because spillages and accidents will happen, so you need to ensure that your chosen cool box has surfaces that are easy to wipe down and clean without too much hassle. Easy clean surfaces will also save you time and money in the long run as you won’t need to replace stained cool boxes.

Having a dirty cool box is also a health risk, especially if you have children, so keeping it clean will also keep them safe.


Some cool box models have a multi-use which is achieved by having two independent cooling zones which allow one zone to be used for refrigeration and the other for freezing. This not only saves you money from having to buy two different units but also saves you space as you only need one unit inside your caravan.

Cool Box Tips 

Even if you buy the best cool box on the market, there are several ways that you can get the most out of your cool box to make it perform better and last longer.

Keep it stored in a cool place. Even if you have an electricity source, it must work harder if it’s in direct sunlight so if it’s in your caravan store it in a cupboard and away from windows. If you’ve taken it in your car, then don’t let it just sit in the back seat of your car with the sun pointing straight through the windows.

Even if you’re using a cool electric box restrict the number of times that you open it. Each time you open it, you’ll be letting cool air leave the box, and warmer air will enter which can affect the temperature of the items inside. The more often you open it, the bigger the effect will be.

As a space-saving hack, any food that you have in the cool box should be packed into zip lock bags because this will reduce the amount of space that is used compared to excess food packaging. The zip lock bags will also protect your food against any liquid spillages.

Ideally, you should have separate cool boxes for foods and drinks because you’ll be going into the cool box with drinks far more often than you will for food, so this keeps your food in a better, cooler environment without being constantly compromised. 


The material the cool box is made from will play a key role in how well insulated the cooler is. Generally speaking, the thicker the cool box material, the better the insulation and most cool boxes are made of plastic or foam which works to stop cool air from leaving and from warm air entering.

Cooling Power

Cool boxes will have a measurement that will tell you how many degrees below the ambient temperature that it can reach. This measurement will determine which cool box you buy, and the ambient temperature refers to the temperature reading outside of the cool box. The lower the rating, the lower the temperature that it can maintain.
