Rank #7 in Best Electric Cool Box 2026: 10 Ranked, and Why the Litre Count Misleads
Subcold Euro30 28L Electric Cool Box, 12V/240V
Price and rating as shown on Amazon when we collected them. Both change.
The Subcold Euro30 is an electric cool box that runs from a 12V car socket or a 240V mains plug, and it sits at number 7 in this guide. The listing puts it at £63.74 with a 4.5 out of 5 rating from 77 ratings, and says it holds 45 standard cans. Note what the same listing says about cooling: 15–20°C below the ambient temperature, so the box tracks the air around it rather than holding one fixed temperature the way a compressor fridge does.
The capacity story here is different from most of the category. Subcold gives one figure — 28 litres — with no gross and no net number to compare it against, so there is nothing to contradict. What there is to check is everything around it: the listing claims 1.5L and 2L bottles stand upright inside, and in the same breath gives the chamber depth as 2E+1 centimetres, which is how the listing formats 20cm. The star breakdown shown with the product adds up to 100, while the listing states 77 ratings, so even the review count does not reconcile with itself. Everything on this page comes from the Amazon listing and not from any testing by us.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“A great product which is both versatile by means of dual power connections together with a larger than normal capacityfor a range of items including 1.5 L bottles. A hinged lid which can be held open with the carry handle.Also good value when compared against the competition.”
Verified purchase“Recently used this cool box in a very warm caravan awning - on the coldest setting it kept the various soft drinks stored within refreshingly cold. Just the right size for a small awning and very very quiet. Based on this experience I would recommend this cool box.”

Questions people ask
How much does the Subcold Euro30 hold?
The listing gives a single capacity figure of 28 litres, and says the box holds up to 45 standard cans with room for 1.5L and 2L bottles to stand upright.
How cold does it get?
Subcold states that MAX mode cools drinks and snacks to 15–20°C below the ambient temperature. It does not quote a fixed internal temperature, so how cold things get depends on the air around the box.
Can I run it from the mains?
Yes. The Euro30 is listed for 12V DC in a car, 240V mains at home, and Subcold says it can also run from a portable power station.
How quiet is it?
The listing states a 26dB noise level. One reviewer describes the unit as very, very quiet, which is consistent with that figure.
The chamber depth is listed as 2E+1 centimetres — what does that mean?
That is how the figure appears on the listing; it reads as 20 centimetres. Worth checking if you plan to stand 2L bottles upright, because the same listing claims there is room for them.
What warranty comes with it?
The listing states a 1 year manufacturer warranty, and gives the country of origin as China.
