By [Portable Fridge Guide Editorial Team](https://portablefridgeguide.com/about/) · Updated October 30, 2026 · [How we score](https://portablefridgeguide.com/how-we-research/) Our score comes from manufacturer specs, professional reviews, and owner reports. It is not a hands-on lab test. ## The verdict The CFX2 28 is the sensible way into Dometic's ecosystem: a small, well-supported compressor fridge with an app and a long warranty. It lacks the CFX5's vacuum panels, so it is not the efficiency pick, and budget shoppers get similar capacity from BougeRV or Alpicool for a quarter of the price — buy it for the brand, support and warranty. ### What we like - Compact 28 L footprint (23.6 × 13.6 in) that fits cars where 45 L fridges don't - Same −7°F to 68°F range, 3-stage battery protection and Bluetooth app as Dometic's pricier coolers - Sold and shipped by Amazon; CFX2 listings carry ~159 reviews at 4.5 stars - 5-year limited warranty per Dometic US ### Watch out for - No vacuum insulation and no published Ah/h figure — expect it to use more energy than a CFX5 - About $600 for 30 quarts; ICECO's GO20 and BougeRV's 23-quart cost less per quart - Only 36 cans of space; a week of food for two won't fit ## Score breakdown Cooling & capacity 8.4 Power efficiency 7.6 Build & features 8.4 Value 7.2 30 qt (28 L) · Single zone · 103 W rated ## CFX2 28 specs | Brand | Dometic | | --- | --- | | Capacity | 30 qt (28 L) | | Layout | Single zone | | Cooling | Compressor (Not published) | | Temperature range | -7°F to 68°F | | Rated input power | 103 W | | Average draw | Not published by the maker | | Power | 12/24 V DC + 100–240 V AC (no internal battery) | | AC adapter included | Yes | | Battery protection | 3-stage | | Battery | No battery | | App | Bluetooth app | | Dimensions | 23.6 × 13.6 × 16.8 in | | Weight | 29.3 lb | | Wheels | No | | Warranty | 5-year limited warranty per Dometic US product page | | Price tier | $$ Mid-range ($300–$600).

Confirm on the Amazon page before buying. ## 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](https://portablefridgeguide.com/tools/battery-runtime-calculator/?model=dometic-cfx2-28). 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](https://www.amazon.com/dp/B0DF81CFPP?tag=portablefridgeguide.com-20), and check today’s price. To see whether it fits your trip, try the [fridge matcher](https://portablefridgeguide.com/tools/fridge-matcher/). ## 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](https://portablefridgeguide.com/fridges/bougerv-cr22-23/) costs roughly a quarter as much for a similar job, and the [ICECO GO20](https://portablefridgeguide.com/fridges/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](https://portablefridgeguide.com/posts/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](https://portablefridgeguide.com/posts/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](https://portablefridgeguide.com/tools/battery-runtime-calculator/?model=dometic-cfx2-28) 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](https://portablefridgeguide.com/fridges/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?

Dometic rates it at 28 liters, which converts to about 30 quarts. That's about 36 cans. It's enough for a weekend for one or two people, but a week of food for two won't fit. ### How much power does the CFX2 28 use? Dometic doesn't publish an average Ah/h figure for the CFX2 series on its US pages. Based on its size, we estimate about 216 Wh a day at 90°F outside and 37°F inside. That's our estimate, not a measurement. The CFX2 lacks the CFX5's vacuum insulation, so real-world use may be higher. ### What's the difference between the CFX2 and the CFX5? Both share the −7°F to 68°F range, 3-stage battery protection and a Bluetooth app. The CFX5 adds vacuum-insulated panels and a variable-speed compressor, and Dometic publishes average-draw figures for it. It also costs a lot more: the smallest CFX5, the 25, is about $900. ### Can I run it on AC at home? Yes. It runs on 12/24 V DC or 100–240 V AC. Cooling it down at home the night before a trip saves your vehicle battery a long pull-down. ## Sources - [amazon.com](https://www.amazon.com/dp/B0DF81CFPP?tag=portablefridgeguide.com-20) - [dometic.com](https://www.dometic.com/en-us/product/cfx2-28-electric-cooler-97000040395) - [dometic.com](https://www.dometic.com/en-us/lp/cfx2) Not sold yet? ## Alternatives to the CFX2 28 ![EcoFlow GLACIER Classic 35L](https://portablefridgeguide.com/_astro/ecoflow-glacier-classic-35.BOvSiZZQ_1BQs2x.webp) ### [EcoFlow GLACIER Classic 35L](https://portablefridgeguide.com/fridges/ecoflow-glacier-classic-35/) 7.6 - 37 qt - Single zone - Down to -4°F - Battery included EcoFlow power-station owners who want a cordless fridge with a published, low average draw and IPX4 weather resistance. $$$$ Premium Price tier: Premium today's price on Amazon [Check price on Amazon](https://www.amazon.com/dp/B0F62HMKBX?tag=portablefridgeguide.com-20)[Read the full review](https://portablefridgeguide.com/fridges/ecoflow-glacier-classic-35/) ![Anker SOLIX EverFrost 2 40L](https://portablefridgeguide.com/_astro/anker-everfrost-2-40.CvK9adOb_Z1e2QFE.webp) ### [Anker SOLIX EverFrost 2 40L](https://portablefridgeguide.com/fridges/anker-everfrost-2-40/) 8.2 - 42 qt - Single zone - Down to -4°F - Battery included Beach days, tailgates and car campers who want a cordless fridge they can roll to the site and keep cold for two days without a car battery. $$$$ Premium Price tier: Premium today's price on Amazon [Check price on Amazon](https://www.amazon.com/dp/B0DRCNMMZ9?tag=portablefridgeguide.com-20)[Read the full review](https://portablefridgeguide.com/fridges/anker-everfrost-2-40/) ![BougeRV 23 Quart (CR22)](https://portablefridgeguide.com/_astro/bougerv-cr22-23.-b5XWQnb_1nauzr.webp) ### [BougeRV 23 Quart (CR22)](https://portablefridgeguide.com/fridges/bougerv-cr22-23/) 7.8 - 23 qt - Single zone - Down to -8°F Budget road-trippers who want a real compressor fridge that fits on a back seat for under $160. $$$$ Budget Price tier: Budget today's price on Amazon [Check price on Amazon](https://www.amazon.com/dp/B08G1BBBQW?tag=portablefridgeguide.com-20)[Read the full review](https://portablefridgeguide.com/fridges/bougerv-cr22-23/) [Compare all 14 fridges →](https://portablefridgeguide.com/fridges/) ## Helpful guides [Top picks ### The 7 Best Portable Fridges of 2026: 12V Fridges Ranked by Trip, Power and Budget Best portable 12V fridges of 2026, ranked: ICECO VL45 ProS, VL60 Dual Zone, Anker EverFrost 2, Euhomy 59 qt and more, with power estimates and who each fits.
