For most van builds, a portable Dometic compressor fridge in the 45 to 55 liter class is the right size for one or two people, the dual-zone 75 liter models suit couples or long trips who want a freezer section, the entry-level CFX2 is the lower-cost way into the brand, and the built-in CRX front-loading fridges suit builders who want a fixed install in cabinetry. The CFX3 range is still what many listings show, but several retailers describe it as discontinued and replaced by the newer CFX5 series, so treat the CFX3 as the previous generation; reported energy savings for the CFX5 vary by source, which matters a great deal when your power source is a van battery.
Power is the central van-life consideration. A fridge that draws a modest amount per hour still runs for 24 hours a day, so the daily amp-hour total is what to compare against your battery bank and solar. The figures below come from Dometic’s stated specifications or from independent reviews and are labeled with test conditions where known, because ambient temperature, set temperature and how often the lid is opened change real use significantly.

Dometic Van Fridge Lineup Compared
| Model | Best for | Key stated or reported specs | Notable limits |
|---|---|---|---|
| CFX2 (for example 45) | Budget-minded buyers wanting a simple portable compressor fridge | Dometic lists 45 L, about 16.8 kg and 0.86 Ah/h at 12V (32 C ambient, 4 C internal) for the CFX2 45; Bluetooth; simpler LED display; a small non-refrigerated fresh area on some models | No temperature history in the app per one comparison; ABS handles; no anti-condensation design |
| CFX3 45 | Solo travelers, weekend vans | Previous generation. Dometic lists about 46 L and about 19.4 kg; reviews cite roughly 0.8 to 1.0 Ah/h depending on conditions | Several retailers describe the CFX3 line as discontinued; stock and listings may remain |
| CFX3 55IM | Couples wanting more space and ice | Previous generation. Dometic lists 53 L, about 22.1 kg, 12/24V DC or 100-240V AC, adjustable +20 C to -22 C, integrated ice maker, app control and three-stage battery protection; one review cites about 1.11 Ah/h | Heavy; ice maker adds draw |
| CFX3 75DZ | Longer trips needing a freezer and fridge together | Previous generation. Dometic lists about 74 to 75 L, dual zone (about 45 L plus 30 L); one source cites about 3.04 Ah/h with a 4 C large zone and -15 C small zone | Highest draw; reviewers suggest budgeting 30 to 70 Ah per day depending on conditions |
| CFX5 45 / 55IM / 75DZ | Buyers prioritizing efficiency | Current line. Dometic lists the 55IM at 55 L, about 20.2 kg, 1.21 Ah/h with the ice maker on, and the 75DZ at 75 L, about 27 kg and 2.76 Ah/h in dual-zone use; one reviewer compared daily use at about 20 Ah for the 45 and 55 and about 59 Ah for the 75DZ | Premium tier; OutdoorGearLab notes a finicky latch; warranty is listed as 3 years on Dometic pages for the 55IM and 75DZ, while OutdoorGearLab reports 5 years for the 45 (sources vary) |
| CRX built-in (50, 65, 80, 110, 140) | Fixed installs in cabinetry | Manual dimensions for CRX50 are 390 x 544 x 550 mm; CRX50 is about 46 L total, 12/24V DC, about 40 W and roughly 17 kg per the manual; CRX140 is about 135 L and 65 W | Needs ventilation and a proper cabinet; ambient limits apply |
CFX3: The Familiar Choice

The CFX3 range was the dominant portable fridge in van builds for several years and is now described by several retailers as discontinued. The 55IM in particular offers a color display, Bluetooth and Wi-Fi app control, a removable basket arrangement, a drain plug, a USB port, and what Dometic calls three-stage dynamic battery protection to help keep a starter or house battery from being drained. Dometic lists the temperature range as +20 C to -22 C and notes that contents warm slowly when the fridge is unplugged.
Independent daily-use comparisons put the CFX3 at roughly 41 Ah per day for the 45 and about 47 Ah for the 55 in one reviewer’s comparison, with the 75DZ much higher. Another reviewer’s 48-hour test recorded the 55IM at about 0.95 Ah per hour and the 75DZ at about 1.18 Ah per hour. These numbers differ because the testing conditions differ, which is why you should treat them as a range, not a promise. Retailers report the CFX3 range being replaced by the CFX5, though Dometic’s own pages still list some individual models.
CFX2: The Simpler Entry
The CFX2 is described by reviewers as the entry-level portable line. It uses a series 2 compressor, a simpler LED display and ABS handles, and it lacks the app temperature history and anti-condensation design found on the CFX3. GearJunkie’s coverage found no difference in cool-down time between the CFX2 45 and CFX3 45 and listed the CFX2 at a lower price tier. One comparison table lists the CFX2 45 at 0.86 Ah/h at 32 C ambient, similar to the CFX5 45 and slightly lower than the CFX3 45. For buyers who do not need the display, app or sturdier details, the CFX2 is a reasonable way to get Dometic compressor performance.
CFX5: The Efficiency Upgrade
The CFX5 is the newer premium line. OutdoorGearLab ranked the CFX5 45 first among eleven electric coolers reviewed, citing precise temperature holding, quick chilling, low energy use of about 41 watt-hours over six hours in its measurement, a 5-year limited warranty and good durability. The listed drawbacks were the high price and a finicky lid latch. Some comparisons suggest the CFX5 uses much less energy per day than the CFX3, but Dometic’s own hourly figures for the two 55IM models are close (about 1.11 Ah/h for the CFX3 in one review and 1.21 Ah/h listed for the CFX5 with the ice maker on), so sources disagree and real savings depend on conditions. Compare current spec sheets if your battery bank and solar are modest.
Dual Zone: Is the 75DZ Worth It?
The dual-zone 75DZ gives you a large fridge compartment and a smaller freezer section in one box. That flexibility is valuable for long trips, but it costs energy. Dometic lists the CFX5 75DZ at 2.76 Ah/h in dual-zone use, well above the roughly 1 Ah/h range of the single-zone 45 and 55 models. If you only need a fridge, a 45 or 55 will serve better and leave more battery headroom. If you need frozen food for extended trips, the dual-zone design is more convenient than carrying two separate units.
Built-In Fridges: CRX Series
The CRX series is Dometic’s front-loading, built-in compressor line for vans and campers. Reviewers and the manual describe a 12/24V DC unit that vents from the front, so the grille must stay clear. The manual specifies installing it so warm air can flow away, lists an ambient operating range, and tolerates only brief tilting. Follow the cable gauge the manual specifies for your run length. Cut-out dimensions for the CRX50 (390 x 544 x 550 mm), CRX65, CRX80, CRX110 and CRX140 are in the manual, and a mounting frame is sold as an accessory.
Installing a 12V Fridge Safely
A fridge is a continuous load on your electrical system, so wiring quality matters. Use the cable gauge and fuse size specified in the Dometic manual for your model and run length, fuse the circuit close to the battery or distribution point, and use proper crimped or soldered terminals rather than improvised connections. Undersized cable causes voltage drop, which can trip the fridge’s low-voltage cutoff, and in the worst case it can overheat. Allow ventilation around the compressor, secure the fridge so it cannot move in a crash or on rough roads, and keep it away from any fuel or gas appliances. Because van electrical systems carry high current, consult the manufacturer’s instructions and a qualified installer or auto-electrician if you are unsure about fusing or battery protection settings. If your van has any fuel-burning heater or gas appliance, also fit a working carbon monoxide alarm.
- Set the battery protection level (low, medium or high) to match your battery type.
- Keep the lid seal clean and the vents unobstructed.
- Pre-cool the fridge on shore power or while driving, and load already-chilled food.
Who Should Buy and Who Should Skip
Buy a Dometic if
- You want a proven brand with app control and battery protection.
- You fish, camp or travel for days and want reliable cooling in heat.
- You are willing to pay more for efficiency and build quality.
Skip or look elsewhere if
- You travel for short periods and a quality passive cooler is enough.
- Your budget is tight; brands such as Engel, Iceco and BougeRV are alternatives.
- Weight is critical; compressor fridges are heavy.
How Dometic Compares with Alternatives
OutdoorGearLab names the Engel MT45 and the Renogy 53 quart as alternatives to the CFX5 45, and the BougeRV 23 quart as a budget compact choice. Iceco and Alpicool are other value-focused portable compressor fridges that appeal to budget builders. Dometic’s pitch is refinement, an established dealer network and battery protection features, whereas rivals compete on price and sometimes on features like removable batteries or higher capacity per dollar.
Care and Common Issues
- Defrost and clean the interior regularly; use the drain plug.
- Check the lid latch and seal; OutdoorGearLab flags the latch as finicky on the CFX5 45.
- Avoid blocking vents, and keep the fridge level.
- Do not overpack; airflow around contents helps efficiency.
- In high ambient temperatures expect higher energy use.
Decision Table
| Pick this if… | Choose |
|---|---|
| You want the lowest entry cost in the brand | CFX2 45 |
| You travel solo with a modest battery | CFX5 45 (CFX3 45 only if found in stock) |
| You are a couple wanting more room and optional ice | CFX5 55IM (CFX3 55IM is previous generation) |
| You need a freezer and a fridge together | CFX5 75DZ |
| You want to build the fridge into cabinetry | CRX series |
| Your solar and battery capacity are limited | Compare current Ah/h figures; CFX5 or CFX2 45 |
Frequently Asked Questions
How much power does a Dometic fridge use in a van?
Dometic lists roughly 0.9 to 1.2 Ah per hour for its single-zone 45 to 55 L models under standard conditions (32 C ambient), and about 2.8 to 3 Ah per hour for dual-zone 75 L models. Real daily use ranges widely in reviews, and sources disagree on how much less the CFX5 uses than the CFX3.
Is the CFX3 discontinued?
Several retailers describe the CFX3 range as discontinued and replaced by the CFX5, though Dometic’s own pages still list some CFX3 models. Confirm availability with a retailer before ordering.
What is the difference between CFX2 and CFX3?
The CFX3 has a newer compressor, a color display, app temperature history, metal handles and anti-condensation features, according to retailer comparisons. The CFX2 is simpler and cheaper, and one reviewer found no difference in cool-down time.
Do I need a dual-zone fridge for van life?
Only if you need a freezer. Dual-zone operation draws noticeably more power than single-zone use, so a single-zone 45 or 55 is more battery-friendly.
Can I run a Dometic fridge from solar and a lithium battery?
Yes, many van builders do, provided the battery and solar are sized for the daily draw and the fridge’s battery protection setting suits the battery type. Follow the manual on wiring and fusing.
Do built-in CRX fridges need ventilation?
Yes. The manual describes front venting but still requires clear airflow so warm air can leave the cabinet, and it specifies an ambient operating range. Plan the cabinet around those requirements.
