“Can a power station run my camping fridge?” is the single most common question we get from Aussie campers who are thinking about switching from a fixed dual battery setup to something more portable. The short answer is yes — absolutely. The more useful answer is: for how long, and which one should you buy?
That’s what this guide is about. We’ve done the runtime calculations for every major power station on the market against three real-world fridge types — an efficient premium fridge (Engel MT45F), a popular mid-range fridge (Dometic CFX3 45), and a typical budget unit. No guesswork, no vague claims — just the numbers, and then a clear recommendation for each use case.
Key Takeaways
- A 1000Wh power station runs most 12V fridges for 30-57 hours depending on fridge efficiency
- EcoFlow Delta 2 (1024Wh, ~$1,199) is our top pick — fast solar recharge and LFP battery that lasts 3000+ cycles
- Bluetti AC200P (2000Wh, ~$1,699) is the clear winner for multi-day or base camp use — doubles fridge runtime
- Always plug your fridge into the 12V DC port, not AC — saves 10-15% of your power right away
- Add a 200W solar panel and a 1000Wh station becomes effectively unlimited for fridge use in Australian sun
- The Anker Solix C800 (768Wh, ~$699) is the best value option for weekend trips — 30-44 hours fridge runtime
The Quick Answer — How Do You Calculate Fridge Runtime?
Fridge runtime comes down to one formula. Your power station has a capacity measured in watt-hours (Wh). Your fridge draws a certain amount of energy per hour (also in Wh). Divide the first by the second and you get your runtime — minus a small efficiency loss for the inverter if you’re using AC output.
Runtime Formula
Runtime Formula:
Capacity (Wh) ÷ Average Fridge Draw (Wh/hr) × 0.85 (inverter efficiency) = Runtime (hours)
Example: EcoFlow Delta 2 (1024Wh) ÷ 22Wh/hr (Dometic CFX3 45) × 0.85 = ~40 hours
Using 12V DC output? Skip the 0.85 multiplier — no inverter losses.
The key input is your fridge’s average draw per hour — not the peak compressor draw, but the averaged figure that accounts for the compressor cycling on and off. Here’s what real Aussie camping fridges actually consume:
- Dometic CFX3 45 — approximately 22Wh/hr average (premium, efficient compressor)
- Engel MT45F — approximately 15Wh/hr average (one of the most efficient fridges on the market)
- Budget 45L fridge (BougeRV, Kings, etc.) — approximately 28Wh/hr average (thinner insulation, more compressor cycling)
These figures assume 32°C ambient, fridge set to 4°C, pre-cooled, and lid opened occasionally. Your numbers will vary — hotter conditions push draw up 20-30%, cooler conditions reduce it.
The Single Easiest Win
Plug your 12V fridge into your power station’s 12V car-socket output rather than the AC outlets. Running a 12V fridge through an AC inverter wastes 10-15% of your energy to heat. That efficiency loss is free runtime you’re throwing away — on a 1000Wh station, that’s 100-150Wh, or 4-7 extra hours with an efficient fridge.
Runtime Comparison — All Power Stations vs Real Fridges
This is the table that answers the question. All runtimes use the formula above with 0.85 inverter efficiency applied (assumes AC output). Using 12V DC direct adds roughly 15% to these numbers.
Runtimes calculated as: Capacity (Wh) ÷ Fridge draw (Wh/hr) × 0.85 inverter efficiency. Using 12V DC output adds ~15% to these figures. Actual results vary with ambient temperature, lid-opening frequency, and fridge set temperature.
The takeaway: For a 2-night camping trip, you need roughly 44Wh of runtime for a Dometic-style fridge (48 hours × 22Wh/hr = 1,056Wh before efficiency losses). That means a 1000Wh station is the practical minimum for 2 nights without solar. The Bluetti AC200P doubles that buffer entirely.

Our Top Picks for Running a Camping Fridge
EcoFlow Delta 2
Best Overall for Fridge UseThe EcoFlow Delta 2 wins our top recommendation for one key reason beyond raw capacity: the 500W solar input. Every other power station in this comparison maxes out at 200-700W solar input relative to its capacity — the Delta 2’s 500W ceiling means it recharges faster from solar than anything else at this size. Pair it with a 400W portable solar blanket and you’re pulling 40 amps-equivalent into the station while your fridge draws maybe 1.5A. You will never flatten this system in Australian sun.
The LFP (lithium iron phosphate) battery chemistry also matters for a fridge application specifically — this station gets cycled daily, and LFP handles that far better than NMC chemistry found in some rivals. At 3000+ rated cycles, the Delta 2 will still be going strong when your fridge needs replacing.
For most campers: this is the right answer. It’s not the cheapest, but it’s the one you’ll still be happy with in five years.
- Runs a Dometic CFX3 45 for ~40 hours (AC) or ~46 hours (12V DC)
- LFP battery rated to 3000+ charge cycles — lasts years of regular use
- 500W solar input is class-leading — fully recharges in 2 hours of good sun
- Expandable to 2048Wh with an extra battery if your needs grow
- 5-year warranty — best in class
- App monitoring to track battery and solar in real time
- At 12kg it is heavier than the Jackery 1000 Pro
- Premium price compared to the Anker Solix C800
- Solar cables and adapters are sold separately
Bluetti AC200P
Best for Extended Off-GridThe Bluetti AC200P is a different product for a different type of camper. If the Delta 2 is for the weekender who needs reliable fridge power for 2-3 nights, the AC200P is for the serious overlander who spends weeks at a stretch in the bush. At 2000Wh, you are doubling the capacity of every other option here — and with an efficient fridge like the Engel MT45F, you’re looking at nearly 5 days of fridge runtime before you even need to think about solar.
The weight (27.5kg) is the obvious limitation. This is not a power station you pick up and move around freely. It belongs in a pull-out drawer in your camper trailer, bolted down in a vehicle canopy, or parked permanently in a van. If your camping style suits that, the capacity advantage is enormous.
Worth noting: Bluetti’s newer Delta Pro equivalent (the AC300 + B300 system) offers LFP chemistry, but costs significantly more. The AC200P remains excellent value for the raw watt-hours at ~$1,699.
- Runs a Dometic CFX3 45 for ~77 hours — more than 3 days on a single charge
- Engel MT45F users get an extraordinary ~113 hours (nearly 5 days)
- 700W solar input is the highest in this comparison
- 17 output ports — runs fridge, charging, lighting and more simultaneously
- Well-established Australian support and parts network
- At 27.5kg, this is not a one-person lift — needs a trailer or permanent van install
- NMC battery chemistry means fewer charge cycles than LFP models
- No app connectivity — older design
- Overkill and overpriced if you only need 2-3 nights of fridge power
Jackery Explorer 1000 Pro
Best Proven BrandJackery is the brand that introduced portable power stations to the Australian mainstream, and the Explorer 1000 Pro remains their most popular unit for good reason. At 1002Wh, the runtime is essentially identical to the Delta 2 — a rounding error in practice. The difference shows up at the solar recharge end: the Jackery’s 200W input ceiling means a full recharge from a 200W panel takes around 5 hours of good sun, versus 2 hours for the Delta 2 with a 500W input.
For campers who are mostly recharging overnight from mains or from a vehicle alternator between sites, this doesn’t matter at all. If you’re stationary and relying on solar panels as your primary recharge source, the Delta 2 has a clear advantage. Pick the Jackery if you want the reassurance of the most recognisable brand in the space and a slightly lighter carry.
- Runs a Dometic CFX3 45 for ~39 hours — essentially matched with the Delta 2
- Jackery brand is the most widely known and trusted in Australia
- Lighter than the Delta 2 at 11.5kg
- Quiet, fan-less operation at low loads — no noise when the fridge is the only draw
- LFP battery variant available for longer cycle life
- Standard model uses NMC chemistry — opt for LFP variant if available
- Solar input capped at 200W — slow to recharge vs the Delta 2
- AC charging is slower than EcoFlow rivals
- More expensive than the Delta 2 for similar capacity
Power Station vs Dual Battery System — Which Is Right for You?
This is a legitimate debate and the right answer depends entirely on how you camp.
A dual battery system wired into your vehicle wins if:
- You drive long distances between campsites — the alternator recharges your battery as you travel
- You want the highest possible capacity (you can fit 200-300Ah of lithium in a ute canopy)
- Your vehicle already has a compatible system or you’re building out a touring rig
- You want the battery permanently protected and wired, not carried in and out
A portable power station wins if:
- You fly to a destination and hire a 4WD, or drive a regular car
- You camp at a static base camp for multiple nights — you’re not driving to recharge
- You want the flexibility to bring the power station inside, use it at home, or lend it to a mate
- Your vehicle isn’t set up for a dual battery system and the install cost feels steep
- You want a single unit that serves as both camping power and home emergency backup
The honest truth is that serious overlanders often end up with both: a fixed dual battery system for the vehicle and a portable power station as a secondary backup and camp convenience. But if you’re choosing one, figure out how often you drive between stops. Regular driving = dual battery wins. Base camp style = power station wins.

Adding Solar to Extend Runtime Indefinitely
The real power of a portable power station is what happens when you add solar. A typical 200W portable solar panel in Australian conditions produces around 800-1,000Wh on a good sunny day. Your fridge consumes roughly 360-480Wh per day. The maths work comfortably in your favour.
In practical terms: a 1000Wh power station + a 200W solar panel = you never worry about fridge runtime again in Australia. The sun tops up your station faster than your fridge drains it on any reasonable sunny day.
The key numbers to know for solar pairing:
- 80W panel: marginal — keeps up in mild conditions, falls short on hot days when your fridge works hardest
- 120W panel: the sweet spot for a single fridge in typical conditions
- 200W panel: comfortably runs a fridge plus device charging with energy to spare
The EcoFlow Delta 2’s 500W solar input ceiling matters here — if you run two 200W panels in series, the Delta 2 will absorb all 400W. The Jackery 1000 Pro caps at 200W and can’t take advantage of a two-panel setup.
For a full breakdown of solar panel sizing, charge controller settings, and the best portable panels to pair with a power station, see our portable power station solar charging guide.
Use 12V DC, Not AC — Save 15% of Your Power
Every power station in this comparison has a 12V DC car-socket output (the cigarette-lighter style port). Your 12V camping fridge is designed to run off exactly this — plug it in directly. When you run a 12V fridge through the AC inverter instead, 10-15% of your energy is wasted as heat in the conversion process. On a 40-hour runtime, that’s 4-6 hours of fridge power you’re throwing away. Always use the DC output for your fridge.

Frequently Asked Questions
+ How long will a 1000Wh power station run a camping fridge?
A 1000Wh power station will run a typical 45L camping fridge (like the Dometic CFX3 45, which averages ~22Wh/hr) for approximately 38-40 hours. That's well over a day and a half of continuous runtime. Efficiency fridges like the Engel MT45F (averaging ~15Wh/hr) will stretch a 1000Wh station to nearly 57 hours. Budget fridges with higher draw (~28Wh/hr) will land closer to 30 hours.
+ Can a power station run a 12V fridge indefinitely?
Yes — with the right solar input. A power station paired with a 200W+ solar panel in good Aussie sun will generate enough daily energy (roughly 50-70Wh in good conditions) to more than offset a typical fridge's 22-28Wh/hr average draw. In practice, a 200W panel in summer sun produces 800-1000Wh per day, while your fridge only consumes 360-480Wh per day. The sun keeps you going indefinitely. See our solar charging guide for details.
+ Should I use the AC or DC output on my power station to run a 12V fridge?
Always use the 12V DC output if your power station has one. Running a 12V fridge through the AC inverter wastes 10-15% of your power to inverter conversion losses. Most quality power stations (EcoFlow Delta 2, Jackery 1000 Pro) have a 12V DC car-socket output. Plug your fridge into that instead of the AC outlets and you'll get noticeably longer runtime.
+ What's the minimum power station size for a camping fridge?
For a weekend trip (2 nights), a 400Wh power station like the Bluetti AC60 is the bare minimum — it'll run an efficient fridge like the Engel MT45F for about 23 hours. For anything longer, or if you have a less efficient fridge, step up to 700Wh+ (Anker Solix C800) for a genuine 2-3 night buffer. For extended off-grid trips, 1000Wh+ is the sweet spot.
+ Is a power station or a dual battery system better for running a fridge?
It depends on your setup. A dual battery system wired into your vehicle is the best solution for touring campers who drive regularly between stops — the alternator recharges your battery as you drive. A portable power station wins for campers who fly or drive to a base camp and stay put, people without vehicles capable of supporting a battery system, or anyone who wants a self-contained unit that doubles as emergency backup at home.
+ Can I charge a power station while running a fridge from it?
Yes — this is called pass-through charging and most quality power stations support it. You can connect solar panels to charge the power station while simultaneously running your fridge from it. This is the ideal setup: solar input tops up the station during the day while the fridge runs continuously. Just make sure your solar input (in watts) exceeds or matches your fridge draw to maintain battery level.
