How Much Power Do I Need for Camping? The Complete Guide for Australians
How Much Power Do I Need for Camping? The Complete Guide for Australians
Most people buying a camping power station make the same mistake: they pick a number that sounds big enough, hope for the best, and end up either lugging around more battery than they need — or running out of power on night two.
Neither is fun.
The good news is that working out exactly how much power you need for camping takes about five minutes and requires zero electrical knowledge. You just need to know what you're plugging in, how long you'll run it, and how many nights you're staying out.
This guide walks you through the whole thing — including how to factor in solar panels, what devices actually use in the real world, and which power station size matches your camping style.
Short on time? Here's the quick answer.
Quick Answer — Most Australian Campers Need Between 600Wh and 2,000Wh
| Camping Style | What You're Powering | Recommended Capacity |
|---|---|---|
| Minimalist / hiking | Phone, lights, small speaker | 300–600Wh |
| Weekend couple | Fridge + phones + lights | 600–1,000Wh |
| Family weekend | Fridge + CPAP + fan + lights + devices | 1,000–1,500Wh |
| 4WD / extended off-grid | All of the above + air conditioner capability | 1,500–2,000Wh+ |
If you've got a camp fridge running overnight, you're almost certainly in the 800–1,500Wh range — that single appliance draws more power than everything else combined.
If you're also running a CPAP machine, add another 300–400Wh to whatever number you calculated. CPAP is the most commonly underestimated power draw in caravan and camping setups.
Still want to know your exact number? Here's how to calculate it.
Step-by-Step Power Calculation (The 4-Step Formula)
You don't need a maths degree. You need four numbers and a basic calculator.
The Formula
Total Wh needed = Device Watts × Daily Hours × Number of Days × 1.3
The 1.3 at the end is your buffer — it accounts for battery inefficiency, temperature effects on capacity (Australian heat reduces usable capacity by 10–20%), and the reality that you'll always charge something you forgot to include.
Step 1: List Everything You'll Power
Write down every device you plan to run — fridge, phones, lights, fan, CPAP, laptop, whatever. Don't guess; check the label or look up the wattage.
Step 2: Estimate Daily Hours of Use
How many hours per day will each device actually run? Your fridge runs 24 hours but cycles on and off (estimate 10–12 hours of actual draw). Your lights run 4–6 hours at night. Your phone charges for 1–2 hours.
Step 3: Multiply (Watts × Hours = Daily Wh per Device)
| Device | Watts | Hours/Day | Daily Wh |
|---|---|---|---|
| 40L camp fridge | 45W | 11 hrs | 495Wh |
| Smartphones ×4 | 15W | 2 hrs | 30Wh |
| LED camp lights | 15W | 5 hrs | 75Wh |
| Camping fan | 20W | 8 hrs | 160Wh |
| CPAP (no humidifier) | 40W | 8 hrs | 320Wh |
| Laptop | 60W | 2 hrs | 120Wh |
Step 4: Add Up, Multiply by Days, Add Buffer
Example: couple, 3-night beach trip, fridge + phones + lights + fan
- Daily total: 495 + 30 + 75 + 160 = 760Wh/day
- Over 3 nights: 760 × 3 = 2,280Wh
- With 1.3 buffer: 2,280 × 1.3 = ~2,960Wh total needed
That sounds like a lot — but this is without any solar recharging. If you're running solar panels, your requirement drops dramatically. We'll cover that in the solar section below.
The same couple with a 400W solar panel running 5 hours per day generates 2,000Wh over 3 days — covering almost their entire needs. Their power station becomes a buffer, not their only source.
Camping Device Power Consumption Table
Use this as your reference when building your device list. These are real-world average figures for typical Australian camping gear — not manufacturer best-case specs.
| Device | Typical Wattage | Daily Hours (Typical) | Estimated Daily Wh |
|---|---|---|---|
| 12V camp fridge (40L) | 40–55W | 10–12 hrs (cycling) | 400–600Wh |
| 12V camp fridge (60L) | 50–70W | 10–12 hrs (cycling) | 500–750Wh |
| Smartphone charging (×1) | 10–20W | 1.5–2 hrs | 15–35Wh |
| Tablet charging | 20–30W | 2–3 hrs | 40–90Wh |
| Laptop (15") | 45–65W | 2–3 hrs | 90–195Wh |
| LED camp lights (string) | 10–20W | 5–6 hrs | 50–120Wh |
| Camping fan (12V) | 10–40W | 6–8 hrs | 60–320Wh |
| CPAP (no humidifier) | 30–50W | 7–8 hrs | 210–400Wh |
| CPAP (with humidifier) | 60–100W | 7–8 hrs | 420–800Wh |
| Electric blanket | 60–100W | 4–6 hrs | 240–600Wh |
| Portable speaker | 5–15W | 4–6 hrs | 20–90Wh |
| Camera battery charging | 10–20W | 1–2 hrs | 10–40Wh |
| Drone battery charging | 50–80W | 1–2 hrs | 50–160Wh |
| Mini coffee maker | 600–1,000W | 0.1 hrs | 60–100Wh |
The big takeaway from this table: Your camp fridge is almost always the single biggest power draw — often more than everything else combined. If you're running a fridge, that's the number that determines which power station you need. Everything else is secondary.
Camping Style × Capacity Guide
Not sure where you sit? Find your camping style and work from there.
| Camping Style | Typical Setup | Daily Wh | Power Station Needed |
|---|---|---|---|
| Minimalist | Hiking / backpack camping | Lights + 2 phones | ~100–200Wh/day |
| Beach Weekend | Car camping, no fridge | Lights + 4 phones + speaker | ~200–300Wh/day |
| Weekend Camper | Camp fridge + devices + lights | ~500–700Wh/day | 800–1,000Wh |
| Comfort Camper | Fridge + fan + CPAP + devices | ~800–1,100Wh/day | 1,200–1,600Wh |
| 4WD / Extended | Fridge + CPAP + fan + A/C startup | ~1,000–1,400Wh/day | 2,000Wh+ |
A note on CPAP users: You're the group most likely to underestimate your power needs — and most likely to genuinely need it. If you use a CPAP machine without a humidifier, add 250–400Wh per night to your calculation. With a humidifier, add 450–800Wh. A 1,000Wh station that seems generous quickly becomes tight when a CPAP runs all night.
Trip Length × Recommended Capacity
This is the matrix most guides leave out — and it's where the real planning happens.
The table below assumes moderate comfort camping (fridge + lights + phones + fan, ~700Wh/day base load).
| Trip Length | No Solar | With 200W Solar (5hr sun) | With 400W Solar (5hr sun) |
|---|---|---|---|
| 1 night | 600–800Wh | 400–600Wh | 300–400Wh |
| 2 nights | 1,000–1,300Wh | 600–800Wh | 400–600Wh |
| 3 nights | 1,500–2,000Wh | 800–1,000Wh | 600–800Wh |
| 4 nights | 2,000–2,500Wh | 900–1,100Wh | 700–900Wh |
| 5+ nights | 2,500Wh+ (or solar required) | 1,000–1,200Wh | 800–1,000Wh |
The clear pattern: Solar doesn't just reduce how big a power station you need — it fundamentally changes the maths. A 3-night trip that requires a 1,500–2,000Wh station without solar can be managed comfortably by a 1,000Wh station with a 400W panel. That's roughly a AU$1,000 difference in hardware cost — and a 10 kg difference in weight.
For trips longer than 3 nights without access to powered sites, solar isn't an optional add-on. It's the system.
Adding Solar — How Many Panels Do You Actually Need?
Solar sizing follows a simple formula that works anywhere in Australia:
Solar Panel Watts needed = Daily Wh ÷ Peak Sun Hours ÷ 0.8
The 0.8 accounts for real-world panel efficiency losses — dust, heat, non-optimal angle, partial cloud. Always plan for 80% of theoretical output.
Australian Peak Sun Hours by Region
This is the number of hours per day your panels operate at their rated wattage. It's not total daylight hours — it's the equivalent hours of full-sun output.
| Region | Average Peak Sun Hours | Notes |
|---|---|---|
| Queensland (Brisbane, Cairns) | 5.5–6.5 hrs | Highest solar yield in eastern Australia |
| Northern Territory (Darwin, Alice Springs) | 6.0–7.5 hrs | Best solar conditions in the country |
| Western Australia (Perth, Broome) | 5.5–7.0 hrs | Excellent year-round solar |
| South Australia (Adelaide, Outback) | 5.0–6.5 hrs | Strong summer, moderate winter |
| NSW (Sydney, regional) | 4.5–5.5 hrs | Good summer, lower winter |
| Victoria (Melbourne, high country) | 3.5–5.0 hrs | Lower winter yield; plan conservatively |
| Tasmania | 3.0–4.5 hrs | Plan with larger panel or battery buffer |

Solar Sizing Example
Scenario: Weekend camper in QLD, 700Wh/day load, 6 peak sun hours.
- Solar Watts needed = 700 ÷ 6 ÷ 0.8 = ~146W
- Practical recommendation: One 200W panel covers this comfortably with headroom.
Scenario: Family camper in VIC, 1,100Wh/day load (fridge + CPAP + fan), 4 peak sun hours.
- Solar Watts needed = 1,100 ÷ 4 ÷ 0.8 = ~344W
- Practical recommendation: Two 200W panels, or one 400W panel.
The Critical Match: Solar Input vs Power Station Rating
A power station that only accepts 200W of solar input is a bottleneck — even if you connect a 400W panel, it can only use half the output. Always match your panel wattage to your station's maximum solar input rating.
| Anker SOLIX Model | Max Solar Input | Best Paired With |
|---|---|---|
| C800 Plus | 400W | 1–2 × 200W panels |
| C1000 Gen 2 | 600W | 2–3 × 200W panels |
| C2000 Gen 2 | 1,000W | 2 × 500W or 4 × 200W panels |
The SOLIX C2000 Gen 2's 1,000W solar input is the highest in its class — meaning you never run into the frustrating situation of having panels that your station can't fully utilise. In strong Australian sun, it can fully recharge from flat in under three hours. That's a complete cycle, every sunny day, indefinitely.
Which Anker SOLIX Is Right for Your Trip?
Once you've run the numbers, here's where the SOLIX lineup maps to real camping needs.
Under 800Wh — Anker SOLIX C800 Plus
Best for: Solo or couple beach/weekend camping without heavy appliances.
At 768Wh and under 9 kg, the C800 Plus handles a weekend of phone charging, LED lighting, a fan, and a small fridge without breaking a sweat. It's light enough to carry from the boot to camp in one hand. 400W solar input means a single 200W panel keeps it topped through the day.
When it's not enough: If you're running a camp fridge every night for more than two nights without solar, or if you need CPAP, step up.
800Wh–1,500Wh — Anker SOLIX C1000 Gen 2
Best for: Weekend couples and families — the "just right" station for most Australian campers.
At 1,056Wh and 1,500W continuous output, this is the station that handles a real camp setup: 40L fridge running overnight, four phones charging, LED lighting, and a fan — all without watching the percentage anxiously. 600W solar input pairs with two panels for fully self-sufficient weekend camping in most Australian conditions.
Why it's our most recommended station: The C1000 Gen 2 hits the capacity sweet spot for 80% of Australian weekend camping scenarios, without the weight penalty of the larger unit. It's the station most campers end up wishing they'd bought first instead of the undersized alternative.
1,500Wh–2,000Wh+ — Anker SOLIX C2000 Gen 2
Best for: Extended trips, CPAP users, 4WD adventurers, and anyone who wants to run a rooftop A/C.
At 2,048Wh with 4,000W surge and 1,000W solar input, the C2000 Gen 2 is the station for serious Australian camping. It starts caravan air conditioners, runs CPAP machines all night without concern, and — with the Anker Alternator Charger — recharges at 800W while you drive, making every long road leg a charging session.
For grey nomads and extended outback travellers, this is the unit that removes power anxiety entirely. You stop rationing. You stop checking the percentage. You just camp.
Frequently Asked Questions
Is 1,000Wh enough for 3 nights of camping?
It depends on what you're running. For a couple with phones, lights, and a small fan — yes, easily. If you're running a camp fridge, 1,000Wh covers roughly 2 nights without solar input. For 3 nights with a fridge, add a 200W solar panel or step up to a 1,500Wh+ station. The Anker SOLIX C1000 Gen 2 (1,056Wh) paired with a single 200W panel handles 3-night fridge camping comfortably across most of Australia.
How many watt-hours does a 12V camping fridge use per day?
A typical 40L 12V camp fridge draws 40–55W but cycles on and off — effective daily consumption is 400–600Wh, depending on ambient temperature, how often you open it, and contents. In Australian summer heat, plan for the higher end. This single appliance is usually the biggest power draw in any camping setup.
Can a 500Wh power station run a camping fridge overnight?
For one night, yes — just. A 40–55W fridge cycling for 10–12 hours draws approximately 450–550Wh. A 500Wh station running a fridge overnight will reach near-empty by morning, leaving little reserve. For comfortable overnight fridge camping, we recommend a minimum of 800Wh, giving you fridge power plus reserve for lights and charging.
How many solar watts do I need for 3 days of camping?
Using our formula (Daily Wh ÷ Peak Sun Hours ÷ 0.8): for a typical 700Wh/day load in QLD (6 sun hours), you need approximately 150W of solar. A single 200W panel covers it. In Victoria with 4 peak sun hours, the same load needs 220W — two 200W panels recommended. Always match your panel output to your station's solar input limit.
What uses the most power when camping?
In order: camp fridge (400–600Wh/day) → CPAP with humidifier (450–800Wh/night) → CPAP without humidifier (250–400Wh/night) → camping fan (60–320Wh/day) → laptop (90–200Wh/day) → phone charging (15–35Wh per device). If you don't have a fridge or CPAP, your total daily draw drops dramatically and even a 500Wh station can manage a weekend.
How much power does a CPAP use camping?
Without a humidifier: 30–50W for 7–8 hours = approximately 250–400Wh per night. With a humidifier: 60–100W = approximately 450–800Wh per night. CPAP users should always calculate this as the second item after their fridge — it's the most commonly underestimated load in camping power planning. The SOLIX C1000 Gen 2 or C2000 Gen 2 are the recommended stations for CPAP camping with any additional load.
Can I use a portable power station in an Australian national park?
Generally yes — battery power stations are typically permitted in national parks where petrol generators are restricted or banned. Parks Victoria, NSW National Parks, and Queensland Parks all generally allow battery-based units. Always check the specific park's rules before your trip, as conditions vary. Quiet LFP units like the SOLIX range are well within typical park guidelines.
Is 2,000Wh enough for a week of camping?
Without solar, 2,000Wh covers approximately 3–4 days of moderate camping (fridge + devices + lights + fan). For a full week, you need solar input — with a 400W panel generating 2,000Wh over 5 days of good sun, a 2,000Wh station plus solar is genuinely capable of indefinite off-grid operation for most setups. The SOLIX C2000 Gen 2 with 1,000W solar input is designed exactly for this.
What's the difference between watts and watt-hours for camping?
Watts (W) is how fast a device uses power — like speed. Watt-hours (Wh) is how much total power it uses over time — like distance. A 50W fridge running for 10 hours uses 500Wh. Your power station's capacity is measured in Wh. To calculate how long it powers a device: Station Wh ÷ Device W = Hours of runtime.
How do I know if my power station is big enough?
Run the 4-step calculation in this guide. If your result is within 20% of your station's capacity, you're cutting it close — consider adding solar or stepping up one size. If your calculation is more than 50% of your station's capacity for a single day, you'll run flat before the trip ends. The right station should cover 1.5–2x your daily load at minimum, giving you a safety margin for cloudy days and unexpected usage.
