Igloo MaxCold Cool Boxes

Igloo MaxCold cool boxes are passive coolers built around Ultratherm insulation in the body and lid. They don't run on electricity, gas or batteries. You load them with ice or frozen ice packs, close the lid, and the insulation does the rest. Igloo tests the MaxCold range to hold ice for up to 5 days at 32 degrees Celsius ambient temperature, which is a step up from standard cool boxes where the lid is often poorly insulated or left uninsulated altogether.

The MaxCold range includes carry models and wheeled models across several sizes. The MaxCold 50 holds 47 litres and is the most portable option for couples or small families heading out for a weekend. The MaxCold 70 holds 66 litres and fits around 114 standard cans, which suits families on longer camping trips or anyone catering for a group barbecue. The MaxCold 100 is the largest at 95 litres, with a quick-access hatch in the lid so you can grab a drink without opening the full lid and letting cold air escape. For wheeled options, the MaxCold Ice Cube 70 Roller has a telescopic handle and smooth-roll wheels for pulling across campsites, car parks and pavements.

All MaxCold models share the same core features. Reinforced swing-up carry handles with tie-down loops let you strap the cool box down in a car boot, on a boat or in the back of a van. Threaded drain plugs make it simple to empty meltwater without tipping the box over. The lid includes UV inhibitors to prevent sun damage and discolouration over time. Stain and odour-resistant liners help with cleaning between trips. Extended-life hinges and a vinyl-coated stainless steel lid strap add durability.

Passive cool boxes like the MaxCold range work well for camping trips of up to 4 or 5 days if you pack them correctly. Pre-chill the box before loading, use block ice rather than cubed ice (it melts more slowly), and keep the cool box in the shade with the lid closed as much as possible. For longer trips or hotter conditions where you need consistent temperature control without restocking ice, a powered compressor cool box or 12V fridge freezer will give better results. Passive cool boxes have no moving parts, need no power supply and weigh less, which makes them a practical choice for shorter trips, day outings, festivals, fishing and barbecues where simplicity matters more than extended cold storage.

Frequently Asked Questions


How long do Igloo MaxCold cool boxes hold ice?
Igloo tests the MaxCold range to hold ice for up to 5 days at 32 degrees Celsius (90 degrees Fahrenheit) ambient temperature. In real-world camping conditions, ice life depends on how often you open the lid, the outside temperature, whether the box is in shade, and the ratio of ice to contents. Pre-chilling the cool box in advance and using block ice rather than cubed ice both help extend ice retention.
What size Igloo MaxCold cool box do I need for camping?
The MaxCold 50 (47 litres) is a good fit for couples or solo campers on a weekend trip. The MaxCold 70 (66 litres, 114-can capacity) suits families and groups up to about four or five people for a long weekend. The MaxCold 100 (95 litres) is the best option for larger groups, extended trips or anyone catering for a big barbecue. If you're walking any distance from the car to your pitch, the wheeled MaxCold Ice Cube 70 Roller with its telescopic handle makes transport across a campsite much easier.
What's the difference between a passive cool box and a powered cool box?
A passive cool box like the Igloo MaxCold uses insulation and ice to keep contents cold. It has no motor, no power cable, no battery and no moving parts. You fill it with ice or ice packs and the insulation slows the rate at which the ice melts. A powered cool box (thermoelectric or compressor) plugs into 12V, 24V or mains electricity and actively cools to a set temperature. Passive cool boxes are lighter, cheaper, completely silent and need no power source. Powered cool boxes maintain a consistent temperature for as long as they're connected to power, making them better for extended trips.
How do I get the best ice retention from an Igloo MaxCold cool box?
Pre-chill the cool box before loading it by placing a bag of ice inside for a few hours or overnight. Use block ice rather than cubed ice, as larger blocks have less surface area exposed and melt more slowly. Fill any empty space with extra ice or scrunched-up newspaper to reduce the volume of warm air inside. Keep the cool box out of direct sunlight and avoid opening the lid more than necessary. If you're using it in a car, place it in the footwell or boot rather than on the back seat in the sun. Following these steps will get you closer to the tested 5-day ice retention figure.
What is the quick-access hatch on the Igloo MaxCold 100?
The MaxCold 100 has a small opening built into the main lid. It lets you reach in and grab a drink or snack without lifting the full lid. This reduces the amount of cold air that escapes each time you access the cool box, which helps the ice last longer. It's a useful feature on the larger models where the full lid has a bigger opening and loses more cold air when raised.
Are Igloo MaxCold cool boxes suitable for festivals?
They're a solid choice for festivals. They don't need power, so you're not relying on a hook-up or vehicle battery. The 5-day ice retention suits a typical festival weekend. The wheeled models are easier to move across grass and gravel. The tie-down loops on the carry handles mean you can strap it into a car or secure it at your pitch. The main thing to plan for is ice resupply. If the festival runs longer than three or four days and the weather is warm, you'll want to top up the ice if there's a shop or ice vendor on site.
How do I clean an Igloo MaxCold cool box?
Empty the cool box after each trip and drain the meltwater through the threaded drain plug at the base. Wipe the interior with warm water and a mild detergent. For stubborn stains or odours, use a diluted solution of bicarbonate of soda and water. Rinse thoroughly and leave the lid open to air dry before storing. The stain and odour-resistant liner in the MaxCold range helps prevent smells from building up between uses, but drying the box fully before storing it is the most effective way to stop mould or musty smells developing over winter.
