A cool box buys you time. A portable camping fridge removes the question altogether. Where a cool box slowly loses the battle with a hot tent, a proper fridge holds whatever temperature you set it to, in any weather, for as long as it has power. If you are living out of a campervan, camping for more than a couple of nights, or you just want milk that is still milk on day four, this is the category you want.
The catch is that "portable fridge" is a name a lot of products use without earning it. Some of the boxes sold as fridges keep food genuinely cold in any heat, and some just chill it a bit. This guide sorts out which is which, tells you what to spend, and is honest about where the cheaper options make sense. If you actually want a passive cool box or a soft cool bag rather than a powered fridge, that is a separate job and it lives in the best cool boxes UK guide.
Portable fridge or cool box: which do you need?
Be honest about the trip. For a day at the beach or a single overnight, a cool box or cool bag is lighter, cheaper and needs no power. For anything longer, or anywhere hot, a powered fridge earns its place fast.
A fridge needs a power source, weighs more and costs more up front. What you get back is certainty: no ice runs, no soggy food swimming in melt water, no throwing away the ham on the second morning. On a campervan trip with a leisure battery, or a campsite with a hookup, a fridge simply runs and you stop thinking about it.
Which type do you actually need?
There are two kinds of thing sold as a camping fridge, and the difference decides whether your food actually keeps.
The first kind holds a temperature you set, as low as 0C, no matter how hot it is outside, and some will freeze as well. This is a proper fridge. It costs more and wants a decent power source, and it is what you need if the trip depends on food keeping. (If you like the technical name, these are compressor fridges.)
The second kind chills relative to the outside temperature, usually around 15 to 18C below it. On a warm day that is cool, not cold, and it is not really refrigeration. These are cheaper and lighter, and they are often sold with "fridge" in the name, which is where people get caught out. (The technical name is thermoelectric.)
The rule of thumb: if you need food to keep for more than a day or two, or you are somewhere hot, buy a proper fridge. If you just want cold drinks and a bit of chilling for a short trip, the cheaper kind is fine, and you should not pay fridge money for it.
1. Alpicool NCF35: best all-round camping fridge
Alpicool NCF35 35L Fridge
If you want a real fridge without paying premium-brand money, this is the one. The Alpicool NCF35 holds the temperature you set, as low as 0C, and it does it whatever the weather is doing, reaching temperature in about 15 minutes. It will freeze to -20C if you need it to.
It runs off a 12V supply, so it works straight from a car socket, a campervan leisure battery, or a solar and battery setup, and there is a mains adapter for hookups and home. The battery-protection setting watches the voltage and cuts out before it flattens your car battery, which is the feature that stops a fridge ruining your morning. App control lets you set and check the temperature from your phone without opening the lid.
At around £187 for the 35L, with over 500 reviews at 4.5 stars, it is the sensible middle of the market: proper cooling, sensible money. Also sold in 45L and 55L if you need more.
- Holds a set temperature down to 0C in any heat
- Freezes to -20C when you need it
- Runs off 12V, a leisure battery, solar or mains
- Battery-protection cut-off saves your car battery
- App control, and strong value at the price
Most campers and van-lifers who want a real fridge that works in the heat without spending premium money. The default choice unless you need Dometic-level build or a bigger capacity.
2. Igloo and Dometic: the premium fridges
Spend more and you are mostly buying build quality, efficiency and longevity rather than colder food.
Igloo ICF sits in the mid-premium bracket at around £365 to £415. Igloo has decades in cooling, and these are proper fridges for people who want a step up from the value options without going all the way to Dometic.
Dometic CFX5 is the benchmark, and priced like it at roughly £700 and up. Dometic is the brand serious campervan owners fit as standard: efficient, tough, app-controlled, and built to run for years off a leisure battery. If your fridge is going to live in a van and be used constantly, the cost per year of ownership starts to make sense. For occasional camping it is more than most people need.
Both ranges are stocked at Blacks, with live prices below.

The budget route: cheaper coolers
If a proper fridge is more than your trip needs, this is where the money-saving lives, as long as you know these chill rather than refrigerate. They cool relative to the outside temperature, which is fine for drinks and short stays.
Hi-Gear Thermec 25L (~£85) and Hi-Gear 45L (~£130) are Blacks own-brand coolers sold under the fridge name. For occasional use they are a lot of chilling for the money, and the 45L holds a serious amount for a family.
The Hi-Gear 28L 12V/240V (~£74) is the one I actually own and have used for years, so I can vouch for this class of cooler. It has kept milk, butter and leftovers usable in a tent hot enough to be unpleasant, run off the car socket around France and off nothing at all at football tournaments. It will not get things ice cold, but it holds properly cold and the fan is barely noticeable. Mine has survived being dropped through a loft hatch and still works, which says something about how it is built.
On Amazon, the VonShef 24L (~£63) does the same job with three power options and a hot function. For the full picture on these and on passive cool boxes and cool bags, see the best cool boxes UK guide.

A fridge is only as good as its power plan, so think this through before you buy.
12V from the car. Fine while driving, but a fridge left running off the starter battery with the engine off will eventually flatten it. This is why the battery-protection cut-off matters, and why a dedicated leisure battery is the proper answer in a van.
Mains hookup. On a campsite with electric, the mains adapter means the fridge runs indefinitely with no battery worry at all.
Leisure battery and solar. The serious setup: a leisure battery keeps the fridge running overnight, and a solar panel tops it back up by day. A good fridge sips power, which is what makes this workable.
Two more things worth checking: whether you need the freezer function, and the capacity you actually need. Around 1 litre per person per day is a fair starting point, plus room to pack sensibly.
Which one should you buy?
For most people who genuinely want a fridge, the Alpicool NCF35 is the answer: real cooling that holds in the heat, runs off anything, battery protection built in, sensible money. If it is going to live in a van and work every day for years, the Dometic CFX5 justifies its premium, with the Igloo ICF sitting in between.
If you do not actually need refrigeration and just want cheap chilling for drinks and short trips, do not overspend. A cooler like the Hi-Gear 28L does that job well, and the money you save is better kept in your pocket. Just go in knowing it chills rather than refrigerates.
