One of the more stylish cool boxes in our selection and there’s not much wrong to say about this one. It’s large at 32 litre capacity, has two power inputs: 240V AC and 12V DC, a strong carry handle and a relatively quiet cooling fan.

Waeco/Mobicool U32 12 volt and mains camping coolbox

4.3 out of 5 stars (180 Customer reviews)

14 used & new available from £63.00

Our top rated cool box and you can see why. It has approx 29 litre capacity which is big enough to hold 6 one litre bottles standing up. It can cool at up to 18c below ambient temperature. The cooling fan is a little noisy but this shouldn’t affect you most of the time. It does have an ECO mode for quieter operation at night (mains only). It works off 12v or 240v with the cables supplied. The 12v cable is particularly long which is useful.

Coleman Xtreme Passive Coolers

Price: £96.07

4.5 out of 5 stars (305 Customer reviews)

9 used & new available from £89.99

The largest cool box we’ve reviewed coming in at 64 litre capacity. It’s so big that if it’s full you’ll probably need two people to carry it. On the plus side even if you’re shipwrecked you should have enough provisions for quite a while! 
You should drain it every day using the rustproof, leak-resistant channel which means that you don’t need to title it. If you do your food should stay cool for several days. The hinged lid contains deep beverage holders which we like.

This is quite a neat cool box with hidden and protected cable entry and variable handle position. You can use it for heating (50-60C) or cooling (18-25C below ambient temperature). It can be a bit loud but if you’re out on the high seas that won’t bother you.
