While the weather outside right now isn’t exactly ideal for alfresco dining, many of us will be happily and determinedly socialising outside when the weather eventually warms up – making the most of the sunshine when it arrives. Cool boxes are an incredibly practical investment for a number of reasons, but mainly because they’re a simple solution for safely storing food at a colder temperature – excellent for a picnic or barbecue.
Electric cool boxes can be plugged into your car for travelling, while cool bags and backpacks are a great choice for slinging onto your shoulder for adventures.
There are plenty of options on the market, and thinking about how you’ll use your purchase will help you make the right choice for you. Prices can range from very cheap to hugely expensive, so frequency of use and the need for portability are key factors to consider.
To help you choose, we carefully long-listed and tested a selection from a range of brands to hit all budgets. Read on to discover our top cool boxes to buy right now.

Best cool boxes to buy in 2025
Outwell Ecocool slate grey cool box
[squirrel-affiliate-embed widget_type=”text_link” squirrel_id=”544564″ /]
Best cool box
Pros:
- Powered by in-car socket
- Cable storage in lid
- Treated with a biocidal product for antibacterial effect
Cons:
- Air vents must not be blocked
- Energy rating F on the EEI scale despite its ‘eco’ name
Star rating: 5/5
This cooler ticked all of our boxes, from great cooling capacity to performance. It’s a well-thought-out bit of kit. There’s a rectangular water bottle which doubles as an ice pack and slots handily in the box as a divider, helping to maintain a low temperature.
It can be powered both to heat and cool, either in the car or with a mains plug, giving it versatility. Effort has obviously gone into the technology behind its energy efficiency, but its performance is more impressive than the eco credentials its name suggests.

Yeti Roadie 24 cooler
[squirrel-affiliate-embed widget_type=”text_link” squirrel_id=”649251″ /]
Best investment cool box
Pros:
- Well-made and hardwearing
- Available in lots of colours
- Sturdy construction protects contents
- Yeti ice packs available to buy separately
- Robust rubber feet
Cons:
- Expensive
- Heavy
Star rating: 5/5
This investment-level cool box is certainly pricey, but for the money you’ll get a top-notch, hardwearing piece of kit that should stand the test of time. It’s heavy and weighs in at almost 6kg when empty, so despite having a sturdy, comfortable handle, you won’t want to carry it too far – making it best suited to road trips, camping, or boat trips.
The lid locks firmly in place with two latches that help it form a tight seal. With the addition of a bag of ice, it kept our selection of drinks cold for an impressive 36 hours, but this will be reduced if you open it frequently.

Igloo MaxCold 40 Ice 38-litre wheeled cool box
[squirrel-affiliate-embed widget_type=”text_link” squirrel_id=”544561″ /]
Best large cool box
Pros:
- Reasonably priced
- Robust design
- Spacious interior
- Sturdy construction protects contents
Cons:
- Lid doesn’t have a latch or lock
Star rating: 5/5
This is a large-capacity rugged cool box with chunky wheels. It’s ideal for camping trips or festivals where you can’t park very close to your tent. Plus, the effective insulation can keep food cold for days under the right conditions. We filled it with food, drinks, and a bag of ice, and it was all still chilled 36 hours later.
At around 4kg it’s not too heavy, even when full. It’s well balanced with a big handle that’s sturdy and comfortable, so it doesn’t feel heavy to pull along. There’s plenty of space inside for bottles to stand upright and the simple shape means it’s easy to pack. The lid forms a tight seal, although we would have liked to see a latch to lock it closed.

Coleman Convoy 65 QT Wheeled Cool Box
[squirrel-affiliate-embed widget_type=”text_link” squirrel_id=”647381″ /]
Best cool box on wheels
Pros:
- Easy to move
- Can be used as a seat
- Anti-bacterial lining helps avoid odours
Cons:
- Expensive
- One large space, so pack carefully
Star rating: 5/5
You can imagine the coolest crew at the festival rocking up with this amazing box on wheels – and with its whopping 66-litre capacity, there will be more than enough chilled drinks to go round.
Large bottles can be stored upright, and there’s plenty of space to pack picnic goodies for everyone, so it’s a great choice for larger families or for those who are entertaining al fresco. Obviously, if you’re travelling light, things could shift to the end of the box when on the move, so if not packed to capacity, we’d recommend adding some tea towels or extra protection to the bottom to avoid things getting squashed to one side.
The foldable handle and chunky wheels make this large box easy to manoeuvre even over grass or on the beach, and it feels top quality, with substantial rubber fastenings, side rope handles and stainless steel hinges. It’s so sturdy, the Have-A-Seat box lid can also be used as a handy perch for your guests.

Hydro Flask Carry Out Soft Cooler
[squirrel-affiliate-embed widget_type=”text_link” squirrel_id=”649252″ /]
Best cool bag
Pros
- Comfortable, padded carry strap
- Inner pockets for smaller items
- BPA-free lining
Cons
- Larger items had to be stacked rather than storing side by side
Star rating: 4.5/5
One of the most stylish cooler bags we looked at, the structured walls of this lightweight carry bag meant that more delicate items weren’t bashed on the way to our park lunch.
We also liked the shape, as it was taller than some other cool bags we tried, meaning our own lengthier water bottles could stay upright on the way to the park. It will also take 20 330ml-sized cans of drink (without ice packs) if you’re catering for thirsty kids.
In a range of pale pastel colours, the water resistance on this cool bag’s outer fabric was easy to keep clean with a damp cloth after use. The wide, zipped lid also made every area inside the bag easy to access and keep free of sandwich crumbs. We liked the longer, removable cross-body strap, too, which had great padding, making it comfortable to wear for the designated picnic pack horse.
A small outside pouch was useful for stashing things like condiments and salt and pepper. With 24-hour cooling, we could keep a range of picnic foods out overnight, with a couple of ice packs at either side. By lunchtime the next day, wine was still perfectly chilled and our food items were at the perfect temperature, although our ice packs had almost completely thawed out.

Petromax 25l Cool Box
[squirrel-affiliate-embed widget_type=”text_link” squirrel_id=”649253″ /]
Best cool box for camping
Pros
- Superb insulation
- Keeps ice frozen for days
- Spacious
Cons
- Expensive
- Large capacity means it can be heavy to shift when full
Star rating: 4.5/5
If you’re the sort of person who spends sunny days on the patio with the barbie going full blast, this cool box could almost be seen as a mini chiller that will free up space in your kitchen fridge. There’s also a 50-litre version that could handle an entire family’s worth of food for the week.
We kept bags of ice and freezer blocks in this unit, and they were still practically intact six days later when we went to add our picnic ingredients – with just the tiniest bit of water collecting on the bottom of the unit. The manufacturers claim the box will still keep ice frozen for up to 12 days without electricity, which is ideal if there’s no power source for a mini fridge in a summer house or home office, for example.
With integrated handles on either side, it may well be a two-man job to move this cooler from car to picnic blanket once loaded up, so it’s more of a choice for those who like to have barbecue food and ice-cold drinks close at hand in the garden, caravan or camper van.
The double-walled insulation on the Petromax cool box was superb, but that does come at a price. But if, for example, you’re loading for a weekend in the open air, you can rely on this quality box to keep everything in tip-top condition until it’s time to head home.

Red 15L insulated cooler backpack
Available from Red Original (£81)
Best insulated cooler backpack
Pros:
- Lightweight
- Excellent insulation
- Eco-conscious TPU
- BPA-free inner lining
Cons:
- Stiff top zipper
Star rating: 4.5/5
The boxy external structure of this backpack is self -supporting, covered with an impressively durable TPU fabric. The padded straps and back panel made wearing it a comfortable experience, although the chest strap came into play when fully loaded.
We found its 15-litre capacity was enough space to stack lunch for four, helped by the two high bottle pouches, which encased a tall water bottle in one side and two cans of beer stacked in the other. The only downside is the stiffness of its zip – responsible for it’s impressive leakproof credentials. The added bungee storage pocket held a scrunched up jacket whilst keys and a phone fitted in the top zip pouch.

Campos cool box
[squirrel-affiliate-embed widget_type=”text_link” squirrel_id=”544580″ /]
Best budget cool box
Pros:
- Lightweight
- Good insulation
Cons:
- No wheels
Star rating: 4/5
This cooler is lightweight without compromising on sturdiness, making it ideal if you need to carry your supplies over a distance. It also holds 29 litres, so you can really load it up. It’s possible to stand six 1.5-litre bottles in the base, which means soft drinks are covered, as well as wine. We found it retained the temperature well, with a good seal and insulation.

Von Haus 22l Electric Cool Box
[squirrel-affiliate-embed widget_type=”text_link” squirrel_id=”647380″ /]
Best electric cool box
Pros
- Great price
- Easy to carry
- Tall enough for larger bottles
Cons
- Cigarette-lighter style charger may not be suitable for all cars
Star rating: 3.5/5
This box is a great choice for families on the move, as by simply tapping into a power supply from a car’s cigarette lighter, it will keep items chilled for well over the length time you’d expect from a trad cool box. Don’t feed and water the troops at expensive service stations – take drinks and snacks with you and they’ll stay in perfect condition for even the longest summer journey. Once plugged, our ice packs were still frozen after an eight-hour drive from London to Glasgow, with plenty of stop-offs.
The slim, tall shape was great, because it could store wine and 1.5-litre bottles of water, with a roomy single compartment to stack quiches, pork pies and sandwiches for the trip.
As the sides and handle are made from rigid plastic, this bag may not be first choice if you want to walk for a long distance to get to your perfect picnic spot. However, it did make it impossible to squish the strawberries and cream we’d packed, even when a small child decided to use it as an impromptu bench on a tiring country walk.
Guarantee: two years

How to choose the best cool box
Where you plan to use your cooler will affect your choice. They are often made from heavy-duty plastic and insulated with polyurethane foam, which tends to keep food colder for longer. In most cases, you’ll need to add ice packs to keep the temperature down.
Cool bags are generally lighter than cool boxes and once emptied, you can pack them down for easier storage. You may forfeit capacity for portability, as the largest bags will be the heaviest to carry when loaded – which is when wheeled options come into play.
In all cases, think about size. Do you want to be able to stand a litre bottle upright inside, or perhaps you have a casserole dish that needs to sit comfortably in the base?
Electric cool bags and boxes with a cigarette-lighter charging cable are ideal if you’re heading on a long car journey. They increase the duration of cooling, but will add more weight. Once you’ve decided the type of activity you require a cool box for, we recommend considering the following in order to buy one that fulfils every need:
- Weight: a cool box for keeping drinks cold in the garden can be weighty, but if you’re travelling with it over a short distance, a lighter option with wheels will be better.
- Capacity: how many people will you be catering for? The size of cool bags are often described in litres rather than people, but as a rule of thumb, 18 litres will carry between 25-28 cans, 30 litres will fit around 50, and anything above this will be large enough for a variety of food and drink vessels.
- Bag or box: if portability is the goal, cool bags are a much more flexible for transporting, often featuring straps for carrying it over the shoulder or as a rucksack.
- Durability: you want to be confident that a fully packed cool bag or box will be able to support the weight, and also won’t be let down by its handles, straps or wheels when you attempt to move it.
- Easy-clean inner: cool boxes should be wipe-clean and rinsable.
- Waterproof capabilities: particularly important for cooler bags if you’re taking them out and about, but also that the lining is leakproof.
How to clean your cool box
At the end of a long day in the sun, it can be easy to forget to wipe down your cool box, but always at least try to collect crumbs and wipe out any spills immediately.
A combination of bacteria from food stains and hot weather can make things a bit whiffy when you next go to use your box, so use anti-bacterial wipes to tackle this job when you get home, as this will help avoid nasty odours or mould appearing if the weather turns and the box goes back into storage.
What about deep cleaning? Strongly-perfumed sprays and wipes can taint the food you’re next going to pack, so use gentler solutions where possible when it comes to maintaining the interior of your cool box after it’s been packed away.
Use bleach and hot water on the interior of hard-walled boxes, but never apply it neat as this could damage the materials used. Or check the labels – some bags can be machine washed on a delicates setting. If not, then try making a paste of bicarbonate of soda and washing up liquid, then rub with a soft cloth.
When it comes to drying off the bag before use (which is important to avoid mould), get it out into the fresh air to dry naturally. Sunlight can help sort out any staining too.
How we tested cool boxes
Sturdiness: coolers are often heavy when they’re packed as the weight of cans, ice blocks and food all adds up. We wanted handles that made it easy to hold.
Portability: unless you’re only planning to use your cool box in the garden or for fridge overflow, portability is important. Extra points were given where coolers were especially easy to transport.
Keep-cool capability: this was key to our choices, being the primary function of a cool bag or box. A good seal and effective insulation were a must.
Additional features: in-car electric chargers, wheels, drinks holders and easy-carry options were well rated among the sea of products on the market.
Easy to use and clean: anything that carries food needs to be easily cleaned before and after use, so we looked for interiors that could be easily wiped clean.
How we tested: we filled each of the coolers with bags of ice, ice packs, drinks and typical picnic foods. We then checked the contents at intervals using a thermometer and timed how long it took for the ice cubes to melt.
