ICECO VL45 ProS vs Dometic CFX5 55IM: Is the Dometic Worth $450 More?

The ICECO VL45 ProS is our best overall portable fridge: a steel-bodied 45-liter fridge with a Secop compressor for about $749. The Dometic CFX5 55IM is Dometic’s best-insulated single-zone fridge on Amazon, with a built-in ice maker, for about $1,200. Both are serious fridges for car camping, overlanding and vans. The question is whether the Dometic’s extras are worth about $450. We compare them below. One note: the CFX5 45 would be the closer size match, but Amazon only offered it used when we checked, so the 55IM is the CFX5 you can buy new there.

The specs, side by side

Our daily energy estimates come from capacity, so the bigger Dometic shows a higher number. They aren’t measurements, and they ignore the Dometic’s better insulation.

Where the ICECO wins

Value. It costs about $450 less. The VL45 ProS plus its insulated cover (about $119) and OEM slide mount (about $269) still comes in under the price of the Dometic alone. Or put the difference toward a 100 Ah LiFePO4 battery at about $302.

Built for rough roads. The body is steel with corner bumpers, and ICECO says its Secop compressor keeps working at a 40° tilt. ICECO’s manual also rates the fridge to operate in air up to 131°F. The ICECO slide mount is made for this fridge, which is a big part of why it’s our pick for overlanding.

Flexible to install. The lid opens from either side or lifts off, there are DC sockets on both ends, and the AC converter is built in, so there’s no power brick to lose.

Owner record. About 135 Amazon reviews at 4.7 stars, against about 25 at 3.9 for the CFX5 55IM. The Dometic’s reviews mix praise with complaints about temperature control.

Where the Dometic wins

Insulation and efficiency. The CFX5 uses vacuum insulated panels. No one has published a hands-on test of the 55IM, but OutdoorGearLab’s test of the CFX5 45, which shares the same panels and compressor, is among the best results we’ve seen. It held 34.7°F when set to 35°F, chilled warm cans to 35°F in half an hour, and used just 41 Wh over six hours.

The ICECO’s best data comes from a sibling. Gnomad Home ran the smaller VL35 ProS for 123 hours of early-fall camping, packed full and opened several times a day. It averaged 1.76 A, about 508 Wh a day. ICECO’s own lab figure for that model is 430 Wh a day. Those were real camping conditions rather than a lab, so the numbers aren’t directly comparable with OutdoorGearLab’s. Even so, Gnomad found the ProS line drew more than ICECO’s older VL fridges. If you run from a battery for days, the Dometic’s insulation is its strongest argument.

Deeper freeze and an ice maker. The Dometic goes to −7°F, the ICECO to 0°F. The 55IM also has a rapid-freeze plate. Dometic says it makes ice in about 2.5 hours in air up to 90°F while the main compartment runs as a fridge. The compressor runs flat out while it does, so switch it off when you don’t need ice.

App control. Bluetooth monitoring, lid-open alerts and energy tracking. The ICECO has no app.

More space, less weight. About 10 more quarts in a box only 0.25 in longer, though it’s 2 in wider and 0.8 in taller. Despite that, it weighs 44.4 lb against 52 lb for the ICECO.

Warranty. Dometic US lists a 5-year limited warranty on the whole fridge. The Amazon listing says 2 years, so register with Dometic. ICECO covers the compressor for 5 years and everything else for 1.

Power in practice

By our estimate at 90°F outside, a 100 Ah lithium battery with about 90 Ah usable runs the VL45 ProS for about 94 hours and the CFX5 55IM for about 83 hours in fridge-only mode. Those figures come from capacity, so they don’t reflect the Dometic’s insulation advantage or Gnomad’s higher real-world reading for the ICECO line. Making ice adds more. Dometic’s published 1.55 Ah per hour with the ice maker running would empty the same battery in about 58 hours.

Accessories that change the comparison

A few add-ons narrow the gaps between these two:

• Covers. Neither listing includes one. The Dometic CFX 55L cover is about $142 and the ICECO cover about $119. Either one cuts sun heating in a hot cargo area, which matters more for the ICECO since it doesn’t have vacuum panels.
• Monitoring for the ICECO. The VL45 ProS has no app, so a wireless fridge thermometer with a high-temperature alarm (about $40) covers some of what Dometic’s app does. A Victron SmartShunt on your battery shows what the fridge actually draws, which makes it easy to check the efficiency question for yourself.
• Mounting. ICECO’s slide is made for the VL45 ProS. For the Dometic, Dometic’s tie-down kit is about $79, but the listing names CFX3 coolers, so confirm it lines up on a CFX5. If you want a slide for the Dometic, check its footprint against the slide maker’s specs.

Add a cover and a thermometer to the ICECO and you still save more than $250 over the Dometic alone.

Which one should you buy?

Buy the ICECO VL45 ProS if you want a tough fridge for a truck bed or SUV, mostly run it while driving or from a decent battery, plan to fit a slide, and would rather spend the savings on power or a cover.

Buy the Dometic CFX5 55IM if you camp off-grid on a limited battery, want app monitoring, need a deeper freeze, like having fresh ice, or want 58 quarts in a lighter box with a whole-unit warranty.

Want the Dometic name for less? The Dometic CFX2 28 costs about $598–660 with an app and a 5-year warranty from Dometic US, but it holds only 30 quarts and lacks the CFX5’s vacuum panels.

Verdict

Both score 8.4 in our ratings, for different reasons. For most people we’d buy the ICECO VL45 ProS. It does the core job of a 45-liter fridge with proven parts and a rugged build for much less money. The Dometic CFX5 55IM is the better-engineered fridge, and it earns its premium if efficiency on battery, the app and the ice maker matter to you. Check today’s price on both before you buy. If you need a freezer and a fridge at once, look at dual zones instead. Our CFX5 75DZ vs VL75 ProD comparison covers the big ones, and the best portable fridges of 2026 ranks everything.
