Four 45-liter compressor fridges cover most van builds in 2026, and their makers’ own energy numbers differ by more than 2.5x. EcoFlow rates the GLACIER Classic 45L at 190Wh per 24 hours in Eco mode at a 4°C setting. Dometic lists the CFX3 45 at 1.03Ah per hour in a 32°C room. ICECO’s manual for the VL45 ProS gives 0.510kWh per 24 hours, and EUHOMY quotes a 45W average for its 48QT CF-45. In a van, those numbers decide how big your house battery has to be, so this roundup starts with power use and then covers size, zones, apps and price.

The short list
| Pick | Best for | Capacity | Zones | Weight |
|---|---|---|---|---|
| Dometic CFX3 45 | Full-time van life, best app and battery protection | 46 L | Single | 41.2 lb |
| ICECO VL45 ProS | Rough roads, SECOP compressor, long warranty | 45 L (47.5 qt) | Single | 52.1 lb |
| EcoFlow GLACIER Classic 45L | Fridge and freezer at once, optional battery | 45 L | Dual | 51 lb |
| EUHOMY 48QT (CF-45) | Budget builds and weekend vans | 48 qt | Single | 29.3 lb |
Why 45 liters is the van sweet spot
A 45-liter chest fridge fits behind the driver’s seat or slides under a fixed bed in most high-roof vans. That’s enough for one or two people to shop once or twice a week. Go much bigger and you give up floor space and carry more power draw than you need. Go smaller, like the 19-quart class, and you’ll be shopping every couple of days. All four picks here sit in the 45 to 48 quart range, so the choice comes down to energy use, build and features, not size.
Energy use: the number that sizes your battery
A compressor fridge doesn’t run all the time. It cycles on and off, so the useful number is energy per day, not the rated watts. Here is what each maker publishes, along with my conversion to watt-hours per day.
| Fridge | Maker’s figure | Test conditions given | Approx. Wh per day (estimate) |
|---|---|---|---|
| EcoFlow GLACIER Classic 45L | 190Wh / 24h | 25°C room, 4°C setting, Eco mode | 190Wh |
| ICECO VL45 ProS | 0.510kWh / 24h | Not stated in the manual table | 510Wh |
| Dometic CFX3 45 | 1.03Ah / h at 12V | 32°C room, 4°C setting | ~297Wh (1.03Ah × 24h × 12V) |
| EUHOMY 48QT | 45W average | Not stated | Depends on duty cycle; ~360Wh if it ran at 45W one-third of the time |
Don’t rank these from the table alone. EcoFlow tested in a 25°C (77°F) room, while Dometic tested at 32°C (about 90°F), which is a much harder job. A hot van in July can be warmer than either. A fair planning number for any of these 45-liter fridges in summer is 300 to 500Wh a day, and less in spring and fall. That’s my estimate for typical use.
Dometic CFX3 45: the full-time pick
Dometic lists the CFX3 45 at 46 liters and 18.7 kg (41.23 lb), with outside dimensions of 398 × 476 × 694 mm. It runs on 12/24V DC or 100–240V AC. The rated DC current is 8.2A, and Dometic gives 52W on AC. The VMSO3 compressor can cool anywhere from +20°C down to -22°C, so the whole box can work as a deep freezer if you want.
What makes it a van favourite is the electronics. There’s a three-stage battery protection setting that shuts the fridge off before it drains a starter battery. It also has Wi-Fi and Bluetooth for the Dometic app and a 5V/2A USB port. Dometic recommends 39°F for fresh food and 5°F for frozen food, and the app makes it easy to set and check those temperatures from the cab.
The trade-off is the single zone. If you want ice cream and lettuce at the same time, you’ll need a dual-zone model like the GLACIER.
ICECO VL45 ProS: the rugged pick
ICECO builds the VL45 ProS around a SECOP compressor, a brand that has a long history in mobile fridges. The capacity is 45 liters (47.5 qt), the outside measures 28.1 × 15.9 × 18.1 inches, and it weighs 52.14 lb. The steel body accounts for much of that weight, and it’s the reason the ProS is popular with people who drive washboard roads. The range is 0–50°F, which covers both freezing and fresh food in one zone.
ICECO’s manual lists a 45W maximum draw and 0.510kWh per 24 hours. ICECO backs the compressor with a 5-year warranty, the longest here. The multi-directional lid opens from either side, which helps when the fridge is wedged into a cabinet. ICECO’s own site showed it at $699 on sale when I checked.
EcoFlow GLACIER Classic 45L: the dual-zone pick
EcoFlow’s GLACIER Classic 45L splits into two zones, so you can run one side as a fridge and the other as a freezer. It measures 27.8 × 15.8 × 18.9 inches and weighs 51 lb. EcoFlow rates it at 55W and below 38.5dB, with an IPX4 splash rating and a 2-year warranty.
It also has the most published efficiency detail of this group. EcoFlow lists 190Wh per 24 hours at 4°C and 750Wh per 24 hours at -18°C, both in a 25°C room in Eco mode. If you freeze the whole box, plan for about four times the energy.
The unusual part is the optional plug-in battery. It’s a 298Wh NCM pack rated for 800 cycles, and EcoFlow says it gives up to 39 hours of runtime. You can charge the fridge from solar (11–30V, 8A, 110W max), a car socket (100W) or AC (95W). EcoFlow’s Delta 3 Max manual also lists the GLACIER Classic as compatible, which I covered in my Delta 3 Max 12V fridge guide.

EUHOMY 48QT: the budget pick
EUHOMY’s 48QT CF-45 is the lightest fridge here by a wide margin, at 29.3 lb in EUHOMY’s own comparison chart. The listing gives a -4°F to 68°F range and the outside size as 13.78 × 27.44 × 17.72 inches. It runs on 12/24V DC or 110/240V AC, and both adapters come in the box.
EUHOMY quotes a 45W average draw, noise as low as 45dB and ECO and MAX modes. It also has three-level battery protection and app control, features that used to be reserved for the premium brands. EUHOMY says it cools from 68°F to 32°F in about 15 minutes. The listing shows a 1-year manufacturer warranty, and the price in EUHOMY’s chart was about $210 when I checked. It’s the obvious choice for a weekend van or a first build.

How big a battery do you need?
A common van setup is a 12V 100Ah LiFePO4 battery, which stores about 1,280Wh. If you only use 80% to protect the battery, that’s about 1,024Wh. Here’s how long that lasts with no solar or driving, using the daily figures above. These are estimates, not test results.
| Daily fridge use (estimate) | 12V 100Ah (1,024Wh usable) | 12V 200Ah (2,048Wh usable) |
|---|---|---|
| 190Wh (GLACIER, mild weather) | ~5.4 days | ~10.8 days |
| 300Wh (typical summer) | ~3.4 days | ~6.8 days |
| 510Wh (ICECO manual figure) | ~2.0 days | ~4.0 days |
| 750Wh (GLACIER, all freezer) | ~1.4 days | ~2.7 days |
The fridge is rarely the only load, though. Lights, a fan, phones and a laptop can easily add 200–400Wh a day. A 200W roof panel in decent sun often puts back 600–900Wh a day (estimate), which covers a fridge on its own. If you drive most days, a DC-DC charger refills the battery quickly. My camper van electrical build guide walks through the full system.
DC or AC: run the fridge on 12V
All four fridges have 12V compressors, so plug them into DC whenever you can. Running a 12V fridge through an inverter and its AC adapter means two conversions, which wastes power. Plus, an inverter has its own idle draw that keeps running all day. My Delta 3 Max camping test showed DC nearly tripling runtime compared with AC. If you’re also sizing an inverter for a household fridge, read surge watts vs running watts and can a Victron Phoenix 1200 run a fridge first.
Tips to cut fridge power in a van
- Pre-chill at home. Load cold food and run the fridge on shore power the night before. Pulling warm groceries down to temperature takes the most energy.
- Give it air. Compressor fridges reject heat through side vents. A fridge jammed into a closed cabinet runs longer.
- Use Eco mode. The EcoFlow and EUHOMY both list an Eco mode, and the Dometic and ICECO let you set a gentler temperature. Use MAX only for the first pull-down.
- Park in the shade and vent the van. The cooler the van, the less the compressor runs.
- Set fridge temperature sensibly. Dometic’s suggested 39°F is a good target. Going colder costs energy for little benefit.
- Keep it full. Cold food and drinks act as thermal mass. Fill gaps with water bottles.
FAQ
What size 12V fridge is best for van life?
For one or two people, a 40 to 50 liter (about 42 to 53 quart) fridge is the most common choice. It holds a week of food if you shop smart, and it fits in most van layouts.
How much power does a 12V fridge use per day?
Maker figures for these 45-liter models range from 190Wh (EcoFlow, 25°C room, Eco mode) to 510Wh (ICECO manual). For summer planning, 300–500Wh a day is a reasonable estimate.
Can a 100Ah lithium battery run a 12V fridge?
Yes. A 12V 100Ah LiFePO4 battery has about 1,024Wh usable at 80%, which runs a typical 45-liter fridge for roughly two to five days without charging (estimate).
Is a dual-zone fridge worth it?
If you want frozen food and fresh food at the same time, yes. The GLACIER Classic 45L does both. Single-zone fridges like the Dometic CFX3 45 can be set to either fridge or freezer, but not both at once.
Should I run my van fridge on AC or DC?
DC. All four picks have 12V compressors, so using the 12V input skips inverter losses.
Do these fridges protect my starter battery?
Yes. Dometic and EUHOMY both list three-level battery protection. Use the highest cut-off setting when the fridge runs off a starter battery.
My pick
If you live in your van full time, I’d go with the Dometic CFX3 45 for its app and battery protection. If you drive rough roads, I’d pick the ICECO VL45 ProS for its SECOP compressor and long compressor warranty. If you need a freezer and a fridge at the same time, choose the GLACIER Classic 45L, especially if you want its plug-in battery for time away from the van. If you’re on a budget, the EUHOMY 48QT gives you the core features at a fraction of the price. Whichever you choose, run it on 12V and size your battery for summer.
