Our motoring editor answers your questions about cool boxes, so you can pick the perfect one for your next journey

A Also known as a cooler or portable fridge, these versatile containers come in all shapes and sizes — from compact, lunchbox-style coolers ideal for solo adventures to massive chests capable of storing enough food and drinks for an epic road trip along the Wild Atlantic Way. Whether you’re off on a camping trip, braving a staycation, or merely attempting to survive a long car journey, these clever devices stand between you and the horror of room-temperature fizzy drinks.

Q Why should you invest in a cool box?

A Think about all the times you’ve been on a road trip and wished your drinks were still ice-cold or your snacks hadn’t turned into a melted mess. That’s where a cool box comes in handy. They prevent spoilage when you’re away from a fridge. They keep food fresh, drinks properly chilled, and — crucially — are highly portable, often featuring wheels or straps for easy transport. Plus, they can save you money — instead of having to stop on route for pricey convenience store snacks, you can bring your own. And for those who need medication kept cool, a cool box is not just a luxury — it’s a lifesaver.

Q What should you look for when buying a cool box?

A With so many models on the market, choosing the right one can be overwhelming. You need to consider how well it keeps things cold. The secret to a great cool box is top-tier insulation. The thicker and better the insulation, the longer food and drinks stay cold. Some models can retain ice for up to five days! What size do you need? Cool boxes range from compact eight litre models (great for personal use) to 50 litre plus chests (perfect for camping trips and parties). How portable is it? Check for wheels, handles or straps.
