Rank #4 in Best Electric Cool Box 2026: 10 Ranked, and Why the Litre Count Misleads
Amazon Basics 24L Electric Cool Box, 12V/230V
Price and rating as shown on Amazon when we collected them. Both change.
The Amazon Basics Electric Cool Box takes fourth place in our guide to electric cool boxes. It is a 24-litre thermoelectric box that runs from a 12V car socket or a 230V mains plug, priced at £73.45 and rated 4.3 out of 5 from 262 ratings. The reason it lands here is the capacity figure: it is the only box in this guide that states a total volume and a net volume together and keeps them straight — 24 litres total, 22 litres net. That 2-litre gap is the space you cannot pack. Elsewhere in this category the same gap is either left unmentioned or spread across a title, a bullet and a spec table that disagree with each other.
What you get for the money is a box that cools drinks to approximately 6°C at 24°C ambient temperature and warms food to near 50°C. On mains power there is an ECO mode drawing just 8W for overnight use, and that mode is not available on 12V. The lid handle locks the lid down when closed and props it open while you load. Every number on this page is taken from the Amazon listing — we have not tested this cool box ourselves.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“I'm really loving this little travel fridge, and really want to buy another one to double the volume and possible usage scenarios as its exactly what I was after (a compact additional fridge for home, travel and picnics)! It really is just so cute, and I've found its performance (after 6 months of usage) to be excellent! I only use the cold mode as the heater is irrelevant for my needs. Would have preferred an additional 'mid' setting instead but it's impressive how versatile it is with having that all the same! For example when you're camping and cooking on a Trangia you could use it to keep food warm as you build up complex or multi course meals etc!I've used it through winter on quiet/eco mode then through summer on normal mode (louder naturally but not OTT and certainly necessary) ...considering heat waves are the new norm! Throughout this it has been excellent and a cherished addition. It's really well made and designed (it feels very rugged and made of high quality materials)! Essentially, it's incredible value for the price and been used continuously. Further, it can be easily wiped down externally and internally for essential hygiene/cleanliness!With some thoughtful layout you can fit lots of things in it as you can see. (Eggs, tomatoes, Avocados, Peppers, Cheese, Salad, Milk and still space for more)! I purposely purchased a series of stackable Sistema storage boxes (different sizes based on its internal dimensions) these allow me to be flexible in how I use them/it.Temperature retention is excellent but you have to be thoughtful naturally. It shouldn't be left in a hot vehicle but instead kept in cool shade with good ventilation so the temp is always ambient and not allowed to build (go figure)! Every time you open it you let the cold out and warm air in. So don't treat it like a compressor fridge and it will perform very well (be organised and plan)!As it uses a small fan (thermo electric) sure there's noise but it is not overly loud in normal mode. In quiet mode it's like a whisper! My PC workstation produces around as much noise so it's not excessive to me. I wouldn't want to sleep with my head right next to it (I'd use ear plugs for that ) but then I'd place it in an awning or tent annexe also (out of the way) not an issue!The thing that is super useful about it is that in the absence of power its simply reverts to being a cool box! Thus, you can plug it in when you can and then throw a bag of ice in it any other time (or those cute little frozen reusable blocks that you can often get from the facilities of campsites) when in a remote location or setting.Personally I take a remote travel battery with me wherever I go (EcoFlow River 2, Jackery or DJI - they are super useful technologies). My River 2 can easily be used to power this or anything else as it is a very low power device unlike a compressor! Again be organised/plan!I think the size is perfect as its super compact, takes up very little space and if you need more cool storage space simply get another one and divide how they are used (one for frequent opening the other for occasional opening etc). All in all an excellent product and very smitten!”
Verified purchase“Used this on a caravan trip to keep food cold during the journey. Taking advice from other reviews, I ran this empty on full overnight before loading with chilled food and wine. During a warm days journey, plugged into the socket in the car boot on the lowest setting, it kept everything pretty cold. Some bottles were left overnight without power and these were still cold in the morning, a testament to the quality of the insulation.All in all, a good way of transporting and storing chilled food and drink. Just don't expect it to quickly chill food like a fridge - it is designed to keep cold more than make cold.”
