The best 50 litre cool boxes, compared.
Top pick: INSMEER 55 litre cool bag – Highest score at 8.8 for a day you can carry: 55 litres, a strap, and 4.6 from 604 reviews at about £39.99. Ice packs are not included. Best value: JIXUAN 42 litre insulated cooler bag – Most score per pound at about £7.68, and only for a couple of hours. Ten reviews, and the insulation is described as thin. Updated 22.10.2026.
A 50 litre cool box is a passive insulated container for a family picnic, a beach day, a festival, or a short camping trip. It does not make cold. Ice or frozen packs do, and the box only slows warming. You use one in the UK when a fridge is out of reach and food or drinks still need to stay cooler than the air in a car boot. Read the stated capacity in litres on the attribute row, and ignore a title that lists several sizes. A US quart is about 0.946 litres, so a 50 quart hard cooler is about 47 litres. A hard shell suits multi-day ice. A soft bag folds flat and suits a day. A cart helps only if the base matches the bag. Judge the insulation and the seal, not the litre headline. A day-count in the bullets is a maker test, not a measurement in a UK car park. Those checks are set out in the [50 litre cool box buying guide](/hub/diy-supplies/cool-box-50-litres/sub/cool-box-50-litres-buying-guide).

Question 1 of 2
How long do you need it cold?
The INSMEER bag is listed at 55 litres, 45 x 35 x 36 cm and 840 g, and it is the only product in this set with 4.6 from 604 amazon.co.uk reviews. UK reviewers in the Amazon reviews describe it as large enough for a family picnic or beach day, light for that size, and cold for hours when ice packs are used. The listing includes an adjustable padded strap and a bottle opener, and it does not include wheels or ice packs, so the up-to-12-hours line in the bullets depends on packs you buy yourself. A bullet also claims up to 90 cans of 330 ml, which is about 30 litres of cans before ice, not 55 litres of food. One UK review reports ice and a frozen bottle still partly frozen after about 40 hours, with water that did not leak. That is one story, not a lab result, and the material field says nylon while the bullets say 900D Oxford and food-grade PEVA. It is the top pick here when you can carry a full soft bag for a day and you accept that the attribute row says 55 litres rather than 50.
Pros
Cons
Best for: A day picnic, beach, or self-catering trip when you can carry the full bag on a strap.
Less suitable: Anyone who needs wheels, a stated 50 litre attribute row, or ice that lasts a weekend without a hard box.
Specifications
Common questions
Does the INSMEER bag include wheels or ice packs?
The included list is an adjustable strap, a bottle opener, and the cool bag. Wheels and ice packs are not listed. Bullets say to use ice packs for the 12 hour claim.
What size does amazon.co.uk state?
The attribute row says 55 litres, 45 x 35 x 36 cm, and 840 g. A bullet also says 45 x 36 x 35 cm and up to 90 cans of 330 ml by volume.
Is the lining described as food contact?
The bullets say food-grade PEVA. The material-type field says nylon. A food-grade bullet is not a test report on the listing.
The Odoland rolling bag is listed at 45 litres and 3.31 kg for £69.99, with 3.8 from 127 reviews, and it is the only product here whose bullets include six ice packs. The bullets also claim up to 16 hours and up to 72 cans, polyurethane foam, a detachable bag, and a cart, while the included-components field only says cooler box and the attribute row has no dimensions. Of 50 reviews read, five were tagged United Kingdom. Some call the trolley well made and say picnic food stayed cool when extra packs were added. Others say it falls to the side on grass or gravel and is not well balanced. One UK review says a bungee clip snapped after one use, and another says it is not value for money. You are paying the highest price in this set for ice packs and a cart that the UK texts do not agree on, not for a measured 16-hour hold.
Pros
Cons
Best for: A rolling bag when the included ice packs are why you would pay more, and you will try the cart on your own path first.
Less suitable: Anyone who needs a cart that UK reviews already describe as stable on grass, or a stated 50 litre capacity.
Specifications
Common questions
Does this Odoland cooler include ice packs and wheels?
The bullets say six ice packs and a wheeled cart with a detachable bag. The included-components field only says cooler box.
What capacity and weight are listed?
The listing says 45 litres and 3.31 kg. Dimensions are not on the attribute row. Bullets claim up to 16 hours and up to 72 cans.
What do UK reviews say about the trolley?
UK reviews both praise the trolley and say it tips sideways on grass or gravel. One review says a bungee clip snapped on first use.
The JIXUAN bag is listed at 42 litres, 51 x 25.5 x 33 cm and 140 g, at £7.68, with 3.8 from 10 amazon.co.uk reviews. UK reviews call the size large enough for a shop or a day out and call the price good value. They also call the insulation average or not very thick, with cold lasting about a couple of hours. The lining is aluminium foil and polyester, with carry handles and a zip, and the listing does not state wheels, a shoulder strap, ice packs, or a warranty. One UK review says it broke the first time it was used, which is a single report among seven UK-tagged reviews, so the stars are thin evidence. It is the best value here only if you want the lowest price for a short outing and you treat it as a light thermal bag rather than a cooler that holds a picnic all afternoon.
Pros
Cons
Best for: A short shop or a couple of hours out when the lowest price matters more than ice retention.
Less suitable: A full-day picnic, a long walk on the beach, or anyone who needs a cart or a thicker lining.
Specifications
Common questions
Does this JIXUAN bag include wheels or a shoulder strap?
The listing includes carry handles and the bag. It does not list wheels, a shoulder strap, or ice packs.
What capacity and weight does the listing state?
The amazon.co.uk attributes say 42 litres, 51 x 25.5 x 33 cm, and an item weight of 140 g.
How long do UK reviews say it stays cold?
UK reviews describe a couple of hours and call the insulation not very thick. That is review text, not a lab test.
The Dumenix listing is the only one in this set whose attribute row says 50 litres, at 44 x 30 x 38 cm and 1.5 kg, priced at £34.89 with a cart, handle, and wheels included. UK reviews praise the space for a picnic and say the bag can keep food cool for several hours with frozen bottles or ice blocks, which you add yourself because ice packs are not listed. The same reviews call the wheels too small for stones, uneven pavement, sand, or thick grass, and several say the base is shorter than the bag so it tips or will not stand. The handle is described as flimsy or not locking, one review reports a leak from the bottom, and the warranty field says no. Some review text on the parent listing mentions a 35 litre option, so you should confirm the 50 litre variant at checkout. It suits you only if you have read those cart comments and still want a soft 50 litre bag at this price on smooth ground.
Pros
Cons
Best for: A soft 50 litre bag you will pull on smooth ground after you have accepted the cart reviews.
Less suitable: Grass, gravel, sand, or a downhill path, and anyone who needs the cart to stay upright when it is full.
Specifications
Common questions
Does the Dumenix listing include a wheeled cart?
Yes. Included components are an all-terrain cart, the cooler box, a handle, and wheels. Ice packs are not listed.
What capacity is on the attribute row?
The listing states 50 litres and 44 x 30 x 38 cm. Some UK reviews mention a 35 litre option on the same parent listing.
What do UK reviews say about the wheels?
Several UK reviews say the wheels are small, the base is shorter than the bag, and the cart tips. That is review text, not a lab test.
Shelf prices, stars and review counts are the amazon.co.uk figures stored on 19 October 2026. This is not a lab ice test and not a Food Standards Agency temperature check. Each stored score is out of 100 and is shown here divided by 10. Review evidence, the kit for a passive bag near 50 litres, UK review notes, and price fit make the score. The highest score is the top pick. Best value is a different listing: the most score per pound, and only for a couple of hours.
Review evidence
40%Stars out of 5, times 8, times a sample factor: 1.0 at 500 or more reviews, 0.75 from 100 to 499, 0.5 from 20 to 99, and 0.35 below 20. Stars on ten reviews are weaker evidence than stars on several hundred.
Kit near 50 litres
25%Points for a stated capacity in that band, named foam, a carry method that matches the listing, ice packs if the listing includes them, and a warranty line if one is printed.
UK review notes
25%Praise for a day out raises the mark. Repeated faults, a thin cold-hold comment, or a first-use break lower it. This is review text, not a lab hold time.
Price fit
10%A low price scores well only when the bag still has a stated job. The best-value badge is the most score per pound, not a claim that the cheapest bag matches a larger one.
Buy the stated litres, the shell, and the way you will move a full box before you trust a day-count in the bullets. A cool box does not make cold. Ice or gel packs do. A soft bag suits a day. A hard shell is the usual choice for multi-day ice. A cart helps only if it stays upright.
A 50 litre cool box is a passive insulated container for a family picnic, a beach day, a festival, or a short camping trip. It does not make cold. Ice or frozen packs do, and the box only slows warming. Soft bags around 42 to 55 litres fold flat and suit a day. Hard boxes are often sold as 50 quart, which is about 47 litres, because a US quart is about 0.946 litres. Which? describes bags as easier to carry and store, and boxes as colder for longer and more protective.
A parent title can mention 50 litres and still sell a smaller variant. The attribute row is the figure that counts. A 50 quart cooler is about 47 litres, not 50.
Day counts are maker tests, often a shut lid in warm air, not a UK car park. Wheels help only if reviews say the cart stays upright. Grass, gravel, and sand are where the stored cart comments fail.
The box does not make cold. Ice or gel packs do. Keep the lid shut, separate drinks from food if you can, and do not drain cold meltwater early. Perishable food at 8°C or above for four hours is higher risk.
Read the stated capacity in litres on the amazon.co.uk attribute row before the title. A US quart is about 0.946 litres, so a 50 quart hard cooler is about 47 litres. Can counts are not litres. A hard polyurethane shell is the usual choice for multi-day ice. A soft bag folds flat and suits a day. Which? describes bags as easier to carry and store, and boxes as colder for longer and more protective.
Only one listing in this set names ice packs in the bullets. Day-count claims are maker tests, not a shared measurement and not a Food Standards Agency check. Wipe and air-dry PEVA or foil. A food-grade bullet is not a lab certificate. Assimilated Regulation (EC) No 1935/2004 still applies if the lining touches food. Stars on ten reviews are weaker evidence than stars on several hundred. A low price scores as best value only when the bag still has a stated job for a couple of hours.
Three typical situations, each with a recommendation from this comparison.
You want a fold-flat bag for a picnic, beach, or self-catering day, and you can carry it on a strap. The INSMEER 55 litre cool bag is the top pick at about £39.99. It scores 8.8, with 4.6 from 604 reviews. Ice packs and wheels are not in the included list. The attribute row says 55 litres, not 50.
You want the lowest price for a shop or a couple of hours, and you will treat the bag as a light thermal bag. The JIXUAN 42 litre bag is best value at about £7.68. It scores 3.7, with 3.8 from 10 reviews. UK reviews call the insulation thin, and one says it broke on first use.
You cannot carry a full bag and you will try the cart on your own path first. The Odoland 45 litre rolling bag scores 6.1 at about £69.99, and the bullets name six ice packs. UK reviews also say the trolley tips on grass or gravel. The Dumenix row is the only one that states 50 litres, and its cart reviews are mixed too.
The top pick is the INSMEER 55 litre cool bag at about £39.99. It scores 8.8, the highest here, with 4.6 from 604 reviews, a strap, and a six-month warranty on the listing. Ice packs are not included, and the attribute row says 55 litres rather than 50. Best value is the JIXUAN 42 litre bag at about £7.68. It has the most score per pound, at 3.7 from a thin sample of 10 reviews, and only for a couple of hours. That badge does not mean the thin bag matches the 55 litre one.
