- Quart figures for the CFX2 series are converted from Dometic's liter ratings (Dometic markets CFX2 in liters).
- Rated power is computed from Dometic's 8.6 A at 12 V rating (≈103 W).
- Dometic does not publish an average Ah/h consumption figure for the CFX2 series on its US pages.
- We could not load an independent hands-on review of a CFX2 (GearJunkie reviewed the CFX2 45 in Nov 2024 but blocks automated access); scores lean on Dometic's specs and Amazon owner feedback.

How long will a battery run the CFX2 28?
Estimated runtime on a 100 Ah LiFePO4 battery (about 90 Ah usable) with the fridge set to 37°F and the lid mostly closed. Dometic doesn't publish an average draw for this model, so these figures are estimated from its size, calibrated on fridges that do publish one, and are rougher than usual.
| Outside temp | Avg draw | Per day | Runtime | Solar to break even* |
|---|---|---|---|---|
| 70°F | 0.47 Ah/h | ~130 Wh | 8.0 days | ~40 W |
| 85°F | 0.68 Ah/h | ~200 Wh | 5.5 days | ~50 W |
| 100°F | 0.89 Ah/h | ~260 Wh | 4.2 days | ~70 W |
* With 5 peak sun hours and 25% system losses. Freezer settings, frequent opening and warm food all add load. Try your own battery and weather in the battery runtime calculator.
The Dometic CFX2 28 is a small, single-zone compressor fridge. It holds 28 liters, about 30 quarts, and it’s sized to sit on a back seat, in a footwell or between SUV seats. It gives you Dometic’s −7°F to 68°F range, a Bluetooth app and 3-stage battery protection without CFX5 pricing. It’s aimed at solo travelers and couples who want a name-brand car fridge with a long warranty. Expect to pay about $600–660 on Amazon, and check today’s price.

Who the CFX2 28 is for (and who should skip it)
It’s for you if you do day trips, road trips and weekend camping for one or two, and you want a fridge that fits where 45-liter boxes don’t. Its footprint is about 23.6 × 13.6 inches and it weighs about 29 lb empty, so one person can carry it. It’s also a good fit if you value Dometic’s dealer network and warranty more than the lowest price.
Skip it if you’re shopping on value. The BougeRV 23 Quart costs roughly a quarter as much for a similar job, and the ICECO GO20 adds a Secop compressor and a removable dual-zone divider for less. Skip it too if you need room for a week of food, or if you run on a small battery all weekend and want the most efficient fridge possible. For that, a CFX5 is the Dometic to look at. Our best small car fridges roundup covers the whole size class.
Key capabilities
Size and shape. At 28 L it holds about 36 cans. That’s enough for drinks and a couple of days of meals, but not a family’s groceries. The small footprint is the main reason to buy it: it fits cars and crossovers where bigger fridges won’t.
Range. Like Dometic’s pricier models, it’s rated from −7°F to 68°F, so it can work as a true freezer. Because it’s one compartment, you choose between fridge and freezer for the whole box. You can’t split it the way you can with the GO20.
App and battery protection. The Bluetooth app lets you set the temperature and the 3-stage battery protection without reaching into the back seat. The protection setting is what keeps the fridge from draining your starter battery overnight. If you’re not sure which level to pick, see portable fridge battery protection settings.
What it lacks. There’s no vacuum insulation. Dometic doesn’t publish the compressor model or an average-draw figure for the CFX2. We couldn’t load an independent hands-on review of any CFX2 size either, so this review relies on Dometic’s specs and Amazon owner feedback.
Power and practical use
Without a published Ah/h figure, we estimate the CFX2 28 at about 216 Wh a day at 90°F outside and 37°F inside. That comes from our size-based formula, not a measurement. The formula doesn’t account for insulation quality, so we expect the CFX2 to land at or above that figure rather than below it. At that rate, a 100 Ah LiFePO4 battery (about 90 Ah usable) runs it for several days. A small power station with a 12 V outlet gets you through a night or two. Plug in your own battery in the battery runtime calculator to check.
Its peak input is about 103 W, based on Dometic’s 8.6 A rating at 12 V. Compressor fridges cycle on and off, though, so average draw is far lower. The AC cable is in the box. Cool it on AC the night before so the car doesn’t have to handle the first pull-down.
Reliability and warranty
Amazon sells and ships the CFX2 28 directly. The CFX2 listings together show about 159 reviews at 4.5 stars. That’s a good sign, though it’s a modest sample compared with budget fridges that have thousands of reviews. Dometic US lists a 5-year limited warranty on the product page. That’s longer than ICECO’s 1 year on non-compressor parts and much longer than most budget brands. As with any Dometic bought on Amazon, confirm the warranty terms with Dometic and register the fridge.
Bottom line
The CFX2 28 is the sensible way into Dometic’s lineup: a small, well-supported compressor fridge with an app and a long warranty, for about $600. It isn’t the efficiency pick, since it lacks the CFX5’s vacuum panels. It isn’t the value pick either, since budget shoppers get similar capacity from BougeRV or the Alpicool C20 for far less. Buy it for the brand, the support and the warranty, and pick a bigger CFX2 size if 30 quarts feels tight. Not sure about size? Read what size portable fridge do I need.

- 12V wiring16.4 ft 12V/24V Car Fridge DC Power CordUniversal fit
A longer replacement for the short DC cord most fridges ship with, so the fridge can sit in the cargo area while plugged into a dash socket. Fridge-end plugs differ by brand: confirm the connector matches your model before ordering.

The standard overlanding connector for a fused, high-current fridge circuit. It is far more secure than a cigarette-lighter plug on washboard roads.
