Buying Guide

If you talk about the beach, camping or barbecue at your friend’s house, one thing cannot be missing: a large thermal box. Although it is not a product used every week, it is essential to have one of these at home for when the opportunity arises to put beer on ice and have fun with friends.

You have seen the best models in the above ranking. Now, through this guide, you will receive all the important information to choose yours.

What should I know about a large thermal box?

A thermal box’s main function is to maintain the conservation of food and drinks for a long time, at least for 12 hours. For this, they must be filled with ice.

The ideal thermal box contains a good anti-leakage system and has lids with locks that are automatic, in order to avoid problems for the consumer.

It must be easy to handle and must offer a long life if kept properly.

The cooler is ideal as it is only used on special occasions. So you save money that could be spent on investing in a refrigerator or other appliance for refrigeration.

The use of coolers is common in places that are only frequented occasionally by the family, such as an apartment on the beach or a country house.


However, we can find some disadvantages: the large thermal boxes are a bit expensive and can be a frightening initial investment for those who use it only on special occasions.

Despite the long-term benefits, it is difficult to spend a lot without knowing for sure how many times the cooler will be needed for you.

In addition, it is difficult to carry, and requires a lot of care for its maintenance.

Below, we summarize all the advantages and disadvantages necessary to take into account when choosing whether or not to buy a thermal box:


  • Ensure the ideal temperature of food and drinks for up to 12 hours
  • Fits everything needed for leisure with family or friends
  • Save energy
  • They are practical, they can be taken anywhere


  • They are relatively expensive, and are used on a few occasions
  • They are difficult to carry
  • It is necessary to fill them with ice
  • They require a lot of zeal for maintenance

How much?

A 48 L thermal box costs around R $ 300, but you can look for sizes with smaller volumes, depending on your demand.

Generally, a thermal box is purchased for trips or outings with a considerable number of people, so the most frequent models on the market are between 40 and 60 L, which makes the price a little more expensive.

There are brands where a 48 L model can be cheaper, but be aware of the quality of the product, which in these cases must be much lower than the most expensive brands.


Where to buy?

Fishing and mountain stores are the most specialized for the sale of coolers.

But we are talking about a product that is increasingly popular in large chain stores, such as Amazon.

It is worthwhile to follow any promotions in these stores, which usually offer more attractive prices.



Purchasing criteria: Factors for comparing large thermal box models

If you are looking for a large thermal box that will be ideal and last for a long time, we believe that you need to look professionally, such as fishermen or adventurous sports enthusiasts that involve activities on trails or fields.

These professionals take into account the extreme temperature conditions to which they may be subject, and at these times it is essential to have a large thermal box that can handle the job.

A thermal box may not always be used by you, but it is interesting to invest in a product that guarantees that you will not have headaches every time you use it.

When deciding to buy your large thermal box, pay attention to the following points:

  • Inner color
  • Compatibility
  • Good sealing

Next, we’ll detail each one so you can make the best choice.

The color of the inner part

We explain why this is a good parameter: in most thermal boxes, the external part is coated with a material called polyethylene, a type of high density plastic resin that will be resistant to impacts, low temperatures, among other problems.

In the internal content, the best boxes have a polyurethane foam coating, a component that is an excellent thermal insulator.

How to evaluate a model? For its purity and density. In other words: the purer and denser it is, the greater durability and efficiency it will have.

And here is the moment when we find products with dubious quality, because they are made with recycled material, being therefore cheaper and heavier, in addition to being less resistant to impacts and with little thermal efficiency.

This is where we indicate to observe the thermal color of the box.

Do you know the white parts of the box? The whiter the better. This indicates the purity of the material, since a recycled polyethylene will present a gray color and will have an odor that is easy to recognize and that hardly leaves the product.

Compatibility: testing how many cans fit

In many of our descriptions, we use as a parameter the amount of cans that would fit in the models we choose.

We did this because it is very difficult to measure an amount given in volume.

Cans of water, soda or beer are very common in products to be used in a cooler, so they are references that are commonly used in sales of the most well-known brands.

It is important to invest in a product that can be used on the most diverse occasions possible. Take into account not only a weekend in the countryside, but also a barbecue with all family and friends.

After all, coolers are expensive and are not used as often. It is worth investing a little more and be prepared for any type of situation.

Good Sealing

The brands we select contain caps that guarantee a good seal.
This is not just to guarantee the internal thermal preservation of the box (something that in itself is already important).

With a good seal, we can guarantee an aseptic product, which avoids possible problems of contamination of the products, in addition to preventing possible leaks.

So, before you buy your large thermal box, make sure it has a good sealing system.


Have you ever carried a large, full cooler on your back? It can get quite heavy after putting all the drinks and ice in it.

Imagine you park away from the sand strip and need to carry the box for long meters. This can be quite a chore.

If this is a problem for you, it may be better to invest in a model that has wheels, or transport handles for two people to distribute the weight of the box.

Boxes like this tend to be more expensive. If price is more important than weight, consider all the options listed.
