Dometic CFX3 45 — Overview
Dometic is a Swedish company that’s been making mobile cooling solutions since the 1920s. The CFX3 45 is their best-selling model in Australia — a 46-litre fridge/freezer with WiFi app control, a variable-speed VMSO3 compressor, and a build quality that’s designed to last a decade or more. It’s the benchmark that every other 12V fridge in Australia is measured against.
- VMSO3 variable-speed compressor — fast cooling, efficient at temperature
- WiFi and Bluetooth app for temperature monitoring and control
- Built-in USB charging port
- Superior insulation — holds temperature better, compressor runs less
- 3-stage battery protection (adjustable via app)
- Huge accessories ecosystem (fridge slides, covers, baskets)
- 3-year warranty with established Australian service network
- Proven 10–15 year lifespan with regular use
- $1,299 is a significant investment
- Compressor can be slightly noisier at startup than Engel
- WiFi features add complexity — more electronics to potentially fail
- Lid hinges, while functional, feel less overbuilt than Engel's

Head-to-Head Comparison
Cooling Performance
The Dometic CFX3 45 cools down significantly faster. From a 25°C ambient start, expect the Dometic to reach 4°C in 20–30 minutes compared to 45–60 minutes for the Kings. The VMSO3 variable-speed compressor ramps up aggressively on initial cool-down, then backs off once at temperature — a smarter approach than the Kings’ fixed-speed rotary compressor.
Both fridges reach freezer temperatures (-18°C to -20°C). The Dometic gets there faster and holds it more consistently, especially in hot conditions. The Kings can maintain freezer temps in mild weather but starts to labour when ambient temps exceed 35°C.
Winner: Dometic — faster cool-down, better temperature stability
Power Efficiency
The Dometic draws 0.7–1.2A compared to the Kings’ 0.9–1.5A. That gap looks modest on paper, but the real difference is in compressor cycling. The Dometic’s superior insulation means the compressor kicks in less often — so the average draw over 24 hours is meaningfully lower.
On a 100Ah lithium battery:
- Dometic CFX3 45: ~45–65 hours runtime
- Kings 45L: ~40–50 hours runtime
That’s roughly one extra night of camping before you need to recharge with the Dometic. In hot weather, the gap widens further because the Kings’ compressor cycles more aggressively.
Winner: Dometic — draws less power, better insulation reduces cycling
Tip
The power efficiency difference compounds over time. If you’re sizing a solar setup, the Kings needs roughly 20–30% more solar capacity to maintain the same charge level. Over several years, the battery and solar savings from a more efficient fridge partially offset the higher purchase price.
Build Quality and Durability
This is where the $800 gap shows up most clearly. The Dometic CFX3 45 is built with thicker insulation, better seals, stronger hinges, and higher-quality materials throughout. It’s designed to withstand years of corrugated roads, ute trays, and campsite treatment.
The Kings 45L is functional and reasonably well-built for its price — but the materials are noticeably cheaper. Thinner insulation, lighter-gauge construction, and components that feel like they’re built to a tighter cost target (because they are).
The warranty tells the story: Dometic offers 3 years, Kings offers 2 years. More importantly, a Dometic CFX3 is realistically a 10–15 year fridge with regular use, while the Kings is more realistically a 4–7 year fridge. The maths:
- Kings 45L: $499 ÷ 5 years = $100/year
- Dometic CFX3 45: $1,299 ÷ 12 years = $108/year
Nearly identical cost per year — but with the Dometic you get better performance for the entire lifespan and you only buy one fridge.
Winner: Dometic — better materials, longer lifespan, better warranty
Features and Technology
This category isn’t close. The Dometic CFX3 45 includes:
- WiFi and Bluetooth — monitor and adjust temperature from the Dometic app
- Built-in USB-A charging port — keep your phone or headlamp topped up
- 3-stage battery protection — adjustable via app (low/medium/high cutoff)
- Digital display with precise temperature control
The Kings 45L has a basic digital thermostat and that’s it. No WiFi, no app, no USB, no adjustable battery protection.
For some campers, fewer features means fewer things to break — and that’s a valid perspective. But the Dometic’s app control is genuinely useful when your fridge is buried in the back of a packed 4WD and you want to check the temperature without unpacking everything.
Winner: Dometic — WiFi app, USB port, adjustable battery protection
Noise
Neither fridge is silent, but the Dometic is noticeably quieter in day-to-day use. The VMSO3 variable-speed compressor adjusts its output rather than running at full speed every cycle, which produces a gentler hum. The Kings’ fixed-speed rotary compressor starts with an audible kick and runs louder during each cycle.
If you sleep with your fridge near your tent or in the back of a wagon, the Dometic is the more pleasant companion. The Kings isn’t obnoxiously loud, but it’s audible in a quiet campsite — especially at night.
Winner: Dometic — variable-speed is quieter than fixed-speed
Accessories
Dometic has a massive accessories ecosystem: purpose-built fridge slides, insulated covers, transit bags, wire baskets, and mounting brackets designed specifically for CFX3 dimensions. You can also find third-party options from brands like MSA, Clearview, and other Australian manufacturers.
The Kings 45L has a smaller range of purpose-built accessories through 4WD Supacentre. Generic fridge slides will fit, but you won’t find the same variety of tailored options.
Winner: Dometic — larger range of purpose-built and third-party accessories

Who Should Buy Which?
Buy the Kings 45L if:
- Your budget ceiling is $500 and you need a fridge now
- You camp 3–5 times a year in temperate conditions
- You’re testing the 12V fridge lifestyle before committing to premium
- You already have a strong 12V power setup (100Ah+ lithium) to handle the higher draw
- You’re okay replacing the fridge in 4–7 years if it wears out
Buy the Dometic CFX3 45 if:
- You camp 10+ times a year and want a fridge that lasts a decade
- You camp in hot Australian conditions (outback, tropics, summer heat)
- Power efficiency matters — you want to minimise battery and solar requirements
- You value app monitoring, USB charging, and modern features
- You want the widest range of accessories and mounting options
- You do any serious 4WD touring or extended remote trips
Tip
The middle ground: If the Dometic CFX3 45 is out of reach but you want Dometic quality, consider the Dometic CFX3 35 at ~$1,099. You lose 10L of capacity (36L vs 46L), but you get the same VMSO3 compressor, WiFi app, and build quality for $200 less. It’s the sweet spot for couples or solo campers who don’t need 45+ litres.

Our Verdict
Our Verdict
The Dometic CFX3 45 is the better fridge by every objective measure except price. It cools faster, draws less power, handles hot weather better, lasts longer, comes with a better warranty, and includes features the Kings simply doesn’t have. If you can afford it, buy the Dometic — you’ll spend roughly the same per year of ownership and get a vastly better experience.
But the Kings 45L exists for a reason, and that reason is valid. Not everyone can or should spend $1,299 on a camping fridge. If you’re a weekend camper on a budget, the Kings gives you 45 litres of cold storage for $499 and it works. It keeps food cold, it runs off your battery, and it lets you enjoy 12V fridge camping without a four-figure outlay. For that use case, it’s genuine value.
The honest recommendation: if you camp enough to be reading a detailed fridge comparison, you probably camp enough to justify the Dometic. The people who are truly well-served by the Kings are casual campers doing a handful of trips a year — and most of them aren’t comparing specs online. If you’re here, you care about your setup, and the Dometic will reward that for the next decade.

Frequently Asked Questions
+ Is the Dometic CFX3 45 worth $800 more than the Kings 45L?
It depends on how you camp. If you do 10+ trips a year, camp in hot conditions, or plan to keep your fridge for a decade, yes — the Dometic's better insulation, lower power draw, and 10–15 year lifespan make the $800 premium a sound investment. A Dometic at $1,299 lasting 12 years costs $108/year. A Kings at $499 lasting 5 years costs $100/year — and you'll have bought two or three fridges in the same period. For occasional weekend campers doing 3–5 trips a year in mild conditions, the Kings does the job and the $800 savings is hard to argue with.
+ Can the Kings 45L match the Dometic CFX3 in hot weather?
Not really. In mild to warm conditions (up to 30°C ambient), both fridges cool effectively and hold temperature. Once ambient temps hit 35°C+, the Kings' thinner insulation forces the compressor to work harder and cycle more frequently. At 40°C+, the gap widens — the Dometic's superior insulation and VMSO3 variable-speed compressor maintain temperature more consistently while drawing less power. If you camp in the tropics, outback, or during Australian summer, the Dometic handles the heat significantly better.
+ How much battery life do you lose with the Kings compared to Dometic?
On a 100Ah lithium battery, the Dometic CFX3 45 delivers roughly 45–65 hours of runtime while the Kings 45L delivers 40–50 hours. That's a 10–15 hour difference — roughly one extra night of camping before you need to recharge. The gap widens in hot conditions because the Kings' compressor cycles more frequently. If you're running solar, you'll also need a larger panel to keep the Kings topped up. Over a week-long trip, the Dometic's efficiency translates to meaningful battery and solar savings.
+ Is the Kings 45L reliable enough for a weekend camper?
Yes. For 5–10 weekend trips a year in temperate conditions, the Kings 45L is a perfectly functional fridge. It cools to temperature, runs on 12V, and fits a weekend's worth of food and drinks. Most reliability complaints come from heavy-use scenarios — extended touring, extreme heat, and daily use over many years. For its intended market (budget-conscious occasional campers), the Kings delivers genuine value and most owners report positive experiences in the first 2–3 years.
+ What about the Kings vs the Dometic CFX3 35 instead?
The Dometic CFX3 35 at ~$1,099 is a middle-ground option — $600 more than the Kings but $200 less than the CFX3 45. You get Dometic's build quality, WiFi app, and efficient VMSO3 compressor, but in a 36L capacity (vs 45L for the Kings). If capacity matters more than build quality, stick with the Kings. If you can live with 36L and want Dometic reliability at a lower price point, the CFX3 35 is worth considering.
+ Do both fridges have the same accessories available?
No — the Dometic has a significantly larger accessories ecosystem. You can get purpose-built fridge slides, insulated covers, transit bags, wire baskets, and mounting brackets designed specifically for CFX3 models. These accessories are available from Dometic directly and from third-party manufacturers. The Kings 45L has fewer purpose-built accessories, though generic fridge slides and covers will fit. 4WD Supacentre does sell some Kings-specific accessories, but the range is smaller.
