Best 12 V fridge for a camper van: nine compressor fridges compared by fit, weight and draw
· 14 min read
For a built-in galley fridge the Isotherm Cruise 65 wins on every number that fits a van — 65 L at 19 kg in a 448 mm-wide cabinet; for a 380 mm slot it is the Vitrifrigo C51i; for a chest under a bed, the Dometic CFX3 45 is the lightest and narrowest of the premium boxes, and the Alpicool C40 is the budget answer at 13.7 kg. That is the short version of a spec-sheet comparison of nine 12 V compressor fridges — the ones that actually end up in European and North American self-builds — ranked on the things that decide whether a fridge works in a van: how much food per litre of box, how many kilograms per litre, what it costs per litre, and how much floor it takes.
I have not run these side by side (the method box says exactly what I did and did not do). What this guide adds that the tested reviews do not is the layout view: every unit here is a planner preset or a set of dimensions you can drop into your own van in VanPlot and see whether the door clears the aisle and what it does to the axle load before you buy.

How these are rated — and what I did not do
I have not run these units side by side. This is a spec-sheet comparison: every number in the table is a manufacturer or retailer figure, linked per product and checked September 2026. Where makers publish energy figures under different conditions they are shown as reported and kept out of the score, because a number measured at 32 °C cannot be ranked against one measured at 25 °C. What can be ranked fairly is arithmetic on published dimensions, weight, capacity and price — the things that decide whether a unit fits your layout, what it costs you in payload, and what it costs per litre. That is what the score is.
Each metric is scaled 0–10 across this set (best = 10, worst = 0), then weighted:
- Capacity — 20 % (higher is better)
- Litres per external litre — 25 % (higher is better)
- kg per litre — 20 % (lower is better)
- € per litre — 20 % (lower is better)
- Floor footprint — 15 % (lower is better)
- Capacity is the maker's gross litres; external volume is W × H × D as it sits, handles and hinges included where the maker includes them.
- Prices are EUR street prices where the unit is sold in Europe (the planner's presets, checked August 2026) or US list × 0.92 where it is not; the note under each product says which.
- Energy figures are shown as reported and not scored: Dometic states 25 °C ambient, ARB 32 °C, Isotherm and ICECO state no condition.
- n/p = not published by the maker or its retailers at the time of checking; that metric is left out of the product's score, not zeroed.
No affiliate links: product links go to the manufacturer or the spec page the numbers came from. If a spec here is wrong, tell me and I will fix it and note the change.
How to choose: fit, weight, draw
Three decisions come before the brand. Where it lives decides upright or chest: in a galley run, a built-in 380–448 mm cabinet keeps the worktop; under a bed or on a slide, a chest wins on insulation and price per litre but takes a 700 mm bay and a lid’s worth of counter every time you open it. The kitchen dimensions guide has the counter arithmetic; the footprint column in the table is the number to check against your layout.
How many litres is people × days. Two people, four days between shops: 45–50 L. Weekly shopping or a family: 60–65 L. Every extra litre you do not fill is air you cool and weight you carry — the kg-per-litre column runs from 0.29 (Isotherm) to 0.54 (ARB), which is a 12 kg difference on a 45 L box.
What it draws sets the battery. Makers quote 25–45 Ah a day for this class under different conditions; plan on 40–50 Ah in summer. That is roughly a quarter of a 200 Ah lithium bank every day, and the single largest steady load in most vans — the battery and solar sizing post starts from this number, and the roof-capacity table says whether your van can replace it from the roof.
The fridges, in order
1. Isotherm Cruise 65 EleganceBest overall
Overall 9.0/10 · 448 × 527 × 480 mm (113.3 L outside) · 19 kg · ≈ €860 (EU street, planner preset, Aug 2026) · reported: 290 Wh/24 h (Isotherm; conditions not stated)
The arithmetic is not close: 65 L in a cabinet 448 mm wide and 19 kg heavy is 0.57 litres of food per litre of box and 0.29 kg per litre, both the best here by a margin, at the second-lowest price per litre of any built-in. Isotherm's 290 Wh/day claim is also the lowest reported draw in the set, though the conditions are not stated. It is a marine fridge, which shows in the flange mounting and the price list, and 527 mm of height needs a counter at 900 mm or above — but if the galley can take a 448 mm cabinet, this is the fridge.
Reasons to buy
- 65 L in a 448 mm-wide, 19 kg box — the best litres per kilogram of any built-in here
- Lowest reported daily draw in the set
- Danfoss/Secop BD35F, the compressor every marine yard can service
Reasons to avoid
- 527 mm tall: check the counter height leaves a worktop above it
- Door swing needs 480 mm of clear aisle
- Marine pricing and marine dealers
In the planner: pick Fridge and choose the preset “Isotherm Cruise 65” — it drops in at these dimensions and this weight, so the fit and the axle load are checked before you order. Specs: indelwebastomarine.com, norfolkmarine.co.uk.
2. Vitrifrigo C51iBest for narrow galleys
Overall 6.9/10 · 380 × 532 × 524 mm (105.9 L outside) · 17 kg · ≈ €700 (EU street, planner preset, Aug 2026) · reported: 40 W rated, 2.8 A at 12 V (Vitrifrigo); no daily figure published
The 380 mm cabinet is the story. In a 1.2 m galley run that width is the difference between a fridge plus a drawer stack and a fridge plus a gap, and the C51i puts 51 L behind that door at 17 kg — better litres per kilogram than either Dometic upright. It is 524 mm deep, so measure the counter, and Vitrifrigo publishes a rated draw rather than a daily one. Cheapest upright per litre.
Reasons to buy
- 380 mm wide — fits a galley run where a 448 mm unit does not
- 51 L for 17 kg and the lowest price per litre among the uprights
- Same BD35F compressor as the Isotherm
Reasons to avoid
- Deepest of the uprights at 524 mm
- No published daily consumption, so efficiency is unscored
- Mechanical thermostat, no display

3. Alpicool C40Best budget
Overall 6.4/10 · 574 × 419 × 366 mm (88.0 L outside) · 13.7 kg · ≈ €300 (EU street, planner preset, Aug 2026) · reported: not published
Lightest, cheapest, smallest footprint of the chests, and no published consumption figure — the weight saving is thinner walls, and thinner walls mean more compressor time. For a weekend van on a 100 Ah battery it is the sensible buy; for a full-timer the fridge is the largest daily load and this is where not to save.
Reasons to buy
- Lightest and cheapest unit in the guide: 13.7 kg, ≈ €300
- Smallest footprint of the chests
- Enough for a weekend couple
Reasons to avoid
- No published consumption figure at all
- Thin insulation is where the weight went — expect more compressor run time
- Budget compressor and controls
In the planner: pick Chest fridge and choose the preset “Alpicool C40 (budget)” — it drops in at these dimensions and this weight, so the fit and the axle load are checked before you order. Specs: walmart.com, manuals.plus.
4. Dometic CoolMatic CRX 65
Overall 6.1/10 · 448 × 525 × 545 mm (128.2 L outside) · 19 kg · ≈ €1,000 (EU street, planner preset, Aug 2026) · reported: 1.4–1.8 Ah/h depending on ambient (retailer figure)
Fifty-seven litres with a 7 L freezer, in the same 448 mm width as the Isotherm but 65 mm deeper and €140 dearer for eight fewer litres. The retailer-quoted 1.4–1.8 Ah/h is the highest reported draw here. It is a good fridge in the wrong comparison — next to the Cruise 65 it loses every column.
Reasons to buy
- Largest freezer box of the uprights (7 L)
- 57 L at 19 kg
- Same electronics and dealer network as the CRX 50
Reasons to avoid
- Deepest unit in the guide at 545 mm
- Highest price per litre of the uprights
- Reported draw is the highest of the built-ins
In the planner: pick Fridge and choose the preset “Dometic CoolMatic CRX 65” — it drops in at these dimensions and this weight, so the fit and the axle load are checked before you order. Specs: dometic.com, rhinoinstalls.co.uk.
5. Dometic CoolMatic CRX 50
Overall 5.3/10 · 380 × 534 × 500 mm (101.5 L outside) · 17 kg · ≈ €800 (EU street, planner preset, Aug 2026) · reported: 1.1 Ah/h avg at 12 V, 25 °C ambient (Dometic) ≈ 26 Ah/day
The other 380 mm option, with a nicer freezer box and Dometic's variable-speed control, and the most dealers on the continent. What you pay for that is capacity: 45 L is the smallest of the uprights, so its litres-per-box and price-per-litre both trail the Vitrifrigo. The right choice when serviceability outranks six litres.
Reasons to buy
- Same 380 mm width as the Vitrifrigo with a removable freezer box
- Variable-speed compressor; Dometic states a 25 % saving over fixed speed
- Widest dealer and parts network of the uprights
Reasons to avoid
- 45 L is the smallest capacity here for the second-highest upright price
- 500 mm deep plus door swing
- The flush-mount frame is an extra
In the planner: pick Fridge and choose the preset “Dometic CoolMatic CRX 50” — it drops in at these dimensions and this weight, so the fit and the axle load are checked before you order. Specs: dometic.com, nohma.com.
6. Dometic CFX3 45Best portable chest
Overall 3.3/10 · 694 × 476 × 398 mm (131.5 L outside) · 18.7 kg · ≈ €850 (EU street, planner preset, Aug 2026) · reported: 1.03 Ah/h avg at 12 V (Dometic) ≈ 25 Ah/day
The best chest by the numbers and the lightest premium one, which is why it is the default under most European bed platforms. The 398 mm width lets it sit beside a water tank in a garage; the 694 mm length is a full drawer bay. Dometic quotes 1.03 Ah/h — about 25 Ah a day — and the five-year compressor warranty is the longest here. The score is low because chests are inefficient boxes, not because this one is a bad one.
Reasons to buy
- Lightest premium chest here (18.7 kg) and the narrowest at 398 mm
- Variable-speed VMSO3 compressor, app control, freezes to −22 °C
- Five-year compressor warranty
Reasons to avoid
- 694 mm long: it takes a full drawer bay
- Top opening steals the worktop above it whenever it is opened
- Premium price for 46 L
In the planner: pick Chest fridge and choose the preset “Dometic CFX3 45” — it drops in at these dimensions and this weight, so the fit and the axle load are checked before you order. Specs: dometic.com, jacksonsleisure.com.
7. BougeRV CR45Best value chest
Overall 2.9/10 · 711 × 508 × 457 mm (165.1 L outside) · 20 kg · ≈ €450 (US$490 list, ×0.92) · reported: 45 W eco / 60 W max (BougeRV); no daily figure
Dual zone at €450 is the argument, and 20 kg for 45 L is honest. The box is the biggest here for its capacity — 0.27 litres of food per litre of van — and wheels and handles make sense for a fridge that comes out of the van, less so for one built in. Best of the budget chests for anyone who wants a freezer compartment.
Reasons to buy
- Dual zone at a budget price
- Wheels and handle for a portable that actually gets carried
- 45 L at 20 kg
Reasons to avoid
- Bulkiest box here: 711 × 508 × 457 mm outside for 45 L inside
- Lowest litres per external litre in the set
- Generic compressor; warranty support varies by market

8. ICECO VL45 ProS
Overall 2.6/10 · 714 × 460 × 404 mm (132.7 L outside) · 23.6 kg · ≈ €640 (US$694 icecofreezer.com, ×0.92) · reported: 0.347 kWh/24 h, 55 W avg (ICECO lab figure, conditions not stated)
A Secop compressor at €640 is the pitch, and at 45 L for 23.6 kg it is as heavy as the ARB with a longer case (714 mm). If the bay is long and the budget is mid-range, it is the cheapest route to a premium compressor; if the bay is a bed platform, the length is the problem.
Reasons to buy
- Secop compressor at a mid-market price
- Steel body; lid opens from either side
- Cheapest premium-compressor chest per litre
Reasons to avoid
- Longest unit in the guide at 714 mm
- 23.6 kg — as heavy as the ARB
- US brand; European availability and warranty vary
Not a planner preset yet; place a generic item and type these dimensions and weight in. Specs: icecofreezer.com, trail4runner.com.
9. ARB Zero 47 QT single zone
Overall 1.4/10 · 675 × 436 × 423 mm (124.5 L outside) · 23.9 kg · ≈ €1,010 (US$1,100 ARB USA, ×0.92) · reported: 0.8 Ah/h at 5 °C set point, 32 °C ambient (ARB)
Heaviest fridge in the guide and the most expensive per litre, which sinks it in a spec ranking. Its case for the money is the one thing the table cannot score: ARB publishes its draw at 32 °C ambient, the harshest stated condition here, and the steel case and hinge are built for corrugations. An overlanding fridge in a van-conversion comparison.
Reasons to buy
- ARB states its draw at 32 °C ambient — the harshest published condition in this set
- Lowest overall height of the chests (436 mm)
- Steel case, dual-hinge lid, boost mode
Reasons to avoid
- Heaviest fridge in the guide at 23.9 kg
- Highest price for 44 L
- US-market pricing and support in Europe

FAQ
How big a fridge does a camper van need?
For two people, 40–50 L is the working range: a Vitrifrigo C51i (51 L), Dometic CRX 50 (45 L) or CFX3 45 (46 L) holds three to four days of fresh food with a 3–4 L freezer for ice. Full-timers who shop weekly go to 60–65 L — an Isotherm Cruise 65 is 65 L in a 448 mm-wide, 19 kg cabinet. Above that you are carrying air and paying for it in payload and amps.
How much power does a 12 V compressor fridge use per day?
Makers state 25–45 Ah per day at 12 V (300–550 Wh) for a 45–65 L unit: Dometic quotes 1.03–1.1 Ah/h for the CFX3 45 and CRX 50 at 25 °C, Isotherm 290 Wh/24 h for the Cruise 65, ARB 0.8 Ah/h at 32 °C for the Zero 47. Those conditions differ, so they cannot be ranked against each other; in a hot van budget 40–50 Ah a day and size the battery from that.
Upright or chest fridge for a van conversion?
Upright (built-in) if the fridge lives in a galley run: a 380–448 mm-wide cabinet slots under the counter, keeps the worktop above it, and its footprint is 0.19–0.24 m². Chest (portable) if it lives under a bed or on a slide: it holds cold better when opened, costs nothing to install, but its 0.28–0.32 m² footprint and 700 mm length take a whole drawer bay and the lid steals the counter above it whenever you reach in.
What cutout does a built-in 12 V fridge need?
The cabinet's external size plus ventilation: Isotherm publishes 450 × 533 mm for the Cruise 65 (with a 480 mm depth behind it); Dometic and Vitrifrigo sell flush-mount frames sized to the unit. Every compressor fridge also needs an intake and exhaust path for the condenser — a sealed cabinet makes it run hot and long off your battery.
Is a cheap 12 V fridge worth it?
For weekends, yes: an Alpicool C40 is 40 L for 13.7 kg and about €300, the lightest and cheapest unit here. What you give up is published consumption data, insulation thickness (the weight went somewhere) and controls. For a full-time build where the fridge is the largest daily load, the premium compressor and thicker walls of a Dometic, Isotherm or Vitrifrigo pay for themselves in battery you do not have to buy.
