We have listed out below some considerations that will help you find the best cool box for you, as there are many different ones out there on the market.
It is worth just doing the straightforward task of working out how many people there are in your family or group of friends that you are planning to use the cool box for. You need one with sufficient capacity for the number of people and types of food or drinks that you will be taking.
You can get anything from a one-person 4-litre cool box through to ones at 24 or 28 litres which are perfect for families, up to 40 plus litres, which really are a mini-fridge.
The height is an important factor to look into, too, if you want to keep 1.5 or 2-litre bottles upright in your cooler box.
Whether or not you find your cool box easy to carry will be mainly down to its weight, as well as its handle design to a certain extent. Again, weight can vary significantly between cool boxes, but if you select a heavy cool box, make sure to read the reviews about its handle strength and comfort.
Some cool box reviews will specifically say that a cool box really needs two people to carry it when full.
There are also cool boxes that come with wheels, so you do not have to consider carrying them from the car to your chosen location.
Electric or Passive
So, cool boxes are broadly split into two groups, electric cool boxes or ones that use ice blocks or loose ice to cool the contents down, called passive coolers or passive cool boxes.
Electric coolers can be purchased with a 12 V DC connection for use in cars, camper vans or boats or with a 240 V AC mains charger, great for if you are on a campsite with electricity. Some have both, which make them suitable for a whole range of activities!
The best passive cool box will be well insulated with thicker sides and a secure lid.
There are maybe more extra features than you would have thought a cool box could contain, things such as drain plugs so that you can drain away melted ice, a bottle opener, cup holders and the ability to heat up food, as well as keep your contents cold.
A partition may be included in your cool box, or it may come with a stain and odour resistant lining to prevent any contamination from food smells or stains.
We hope this review has helped provide useful information and advice on finding the best cool box. There are many options out there, from small to large, electric to those that can act as a mini-fridge, but rest assured, the perfect cool box is out there and just waiting for you to throw the ice blocks in!
