Around 150Wh to 1,500Wh can cover anything from basic phone charging to a fridge-based weekend setup for most New Zealand camping trips. This guide walks through calculating your actual power needs based on your gear, trip length and available charging methods.
Key Takeaways
- Work out your daily camping energy needs by listing your devices and how long you'll run them.
- Choose a battery capacity that covers your total energy needs, with room for power losses and longer trips.
- Check that the power station's continuous and surge output match your gear, and that it has the right output ports.
- Factor in solar, vehicle or mains charging for longer off-grid trips.
- EcoFlow offers lightweight DC-focused options as well as units with full 230V AC power, so you can match capacity and output to your trip.
What Is the Best Power Station for Camping?
The right camping power station matches battery capacity to what you'll actually use. Phones, lights and cameras may only need a compact unit, while a 12V fridge, fan or CPAP will push your daily energy use higher. Multi-day off-grid camping with Starlink or electric cooking demands significantly more stored energy.
What Size Power Station Do I Need for Camping?
| Camping Setup | Typical Devices | Typical Daily Energy Use | Starting Power Station Capacity |
|---|---|---|---|
| Minimalist / Overnight | Phone, camera, camping lights | 100–200Wh/day | 200–300Wh |
| Weekend Essentials | Phone, lights, fan, occasional laptop | 200–500Wh/day | 400–800Wh |
| Family / Comfort Camping | 12V fridge, lights, fan, devices, CPAP | 500–1,000Wh/day | 800–1,500Wh |
| Extended / Higher-Draw Camping | 12V fridge, CPAP, Starlink, multiple devices, short-use cooking appliances | 1,000Wh+/day | 1,500–2,000Wh+ |
These ranges are starting points — high-draw appliances still need adequate continuous and surge output regardless of Wh capacity.
How to Calculate Your Camping Power Needs Step by Step
Step 1: List the Devices You Plan to Use
Make a complete list of the camping gear and devices for your trip. Separate essential from optional equipment, and note how often each one runs. This gives you a clear overview of your power needs before you start calculating.
Step 2: Check Wattage and Daily Runtime
Find each device's rated power and how many hours a day it'll realistically run — this is your starting point for estimating daily energy needs.
Common Camping Appliance Power Consumption
| Camping Equipment | Typical Running Power | Typical Daily Use | Estimated Daily Energy Use | Planning Notes |
|---|---|---|---|---|
| 12V Compressor Fridge/Freezer | 40–65W when compressor runs | 6–12h equivalent runtime | 240–780Wh | Usually connected all day; hot weather, frequent opening and poor ventilation increase runtime. |
| Starlink Mini | 20–40W average | 4–8h | 80–320Wh | Handy for remote touring and unpowered camps; a DC supply avoids AC conversion losses. |
| Portable Induction Cooktop | 1,800–2,200W rated input | 0.25–0.5h | 450–1,100Wh | Short sessions can still use significant energy — check continuous AC output before use. |
| 12V Diesel Heater | 5–65W during operation | 6–8h | 30–520Wh | Relevant for cold-weather touring, alpine trips and South Island winter camping. |
| CPAP Machine | 30–60W* | 7–8h | 210–480Wh* | Check your own device specs — heated humidification adds significantly to overnight use. |
| Portable Fan | 10–40W | 4–8h | 40–320Wh | Runtime often increases on hot summer trips. |
| Electric Blanket | 50–100W | 3–6h | 150–600Wh | Can become a major overnight load on colder trips. |
| Laptop | 45–100W | 2–4h | 90–400Wh | Remote work and navigation can turn occasional charging into a sizeable daily load. |
| Camera / Drone Battery Charger | 20–80W | 1–2h | 20–160Wh | Multiple batteries raise the daily total on photography trips. |
| LED Camp Lighting | 5–20W | 4–6h | 20–120Wh | Several lights running together can add up. |
| Smartphone / Tablet | 10–30W during charging | 1–2h | 10–60Wh | Usually one of the smallest loads. |
CPAP consumption varies by model and settings — always check your own device's specifications first.
Don't add every maximum figure unless you genuinely expect to use all those devices at that level every day. Continuous loads like fridges dominate total daily Wh, while short-use appliances like induction cooktops need higher output even if their daily energy use is manageable.
Step 3: Calculate Daily Energy Use in Watt-Hours
Watts × Hours Used = Watt-Hours (Wh)
For example, a 50W fan running for 6 hours uses about 300Wh. Add up all your devices for total daily energy demand.
Keep W and Wh separate when choosing a power station. Watts tell you whether the station can run a device at a given moment; watt-hours tell you how much energy the battery stores and help estimate runtime.
Step 4: Add Conversion Losses and a Capacity Buffer
Real-world use draws more from the battery than the simple device total suggests. Add about 20–30% to your calculated energy requirement to account for AC conversion, standby consumption and runtime variation, then compare that buffered figure against the power station's usable capacity.
Step 5: Adjust for Trip Length and Recharging
Multiply your buffered daily energy requirement by the number of days without reliable recharging, then account for what you can realistically recover from solar during stationary periods or vehicle charging while driving. Mains charging becomes available at powered sites, so a multi-day stay at one unpowered campsite usually needs more stored capacity than a trip with regular driving or daily recharging.
Weekend Trip Sizing Example
| Camping Device | Estimated Daily Energy Use |
|---|---|
| Camping lights | 40Wh |
| Fan | 120Wh |
| 12V camping fridge | 400Wh |
| Phone charging | 30Wh |
| Camera charging | 20Wh |
| Total Daily Energy Use | 610Wh |
With a 25% buffer, that becomes about 760Wh per day. For two days without recharge: 610Wh × 1.25 × 2 days ≈ 1,520Wh. Solar or 4WD charging can reduce that stored-capacity requirement if you can reasonably replenish part of the daily load — use a conservative recharge estimate, since cloud, shade and driving time can reduce what you actually recover.
How to Choose the Right Camping Power Station
Check Continuous and Surge Power Output
Add up the wattage of devices you'll run at the same time and compare it with the station's continuous output, and check startup surge requirements for motor-driven gear like compressors and pumps. A battery can hold enough Wh for the day and still fail to start an appliance if its output limit is too low.
Match the Power Outputs to Your Camping Gear
Phones and cameras typically use USB; 12V DC outputs suit camping fridges and compatible equipment; NZ mains-powered appliances need a 230V AC outlet. Before connecting high-draw equipment, check the voltage, current and output limits for each port, and confirm the power station uses the standard NZ/AU-style outlet (AS/NZS 3112 plug configuration).
Balance Portability and Outdoor Durability
More battery capacity means longer runtime, but also more weight and space in the vehicle. Match your unit to how far you'll be carrying it, campsite space, and outdoor conditions. Once capacity and output are settled, work out your solar needs for extended unpowered trips.
How Much Solar Power Do You Need for Longer Camping Trips?
Solar becomes essential for multi-day unpowered campsites without regular mains or vehicle charging access.
Calculate Your Daily Solar Recharge Needs
If your campsite uses 600Wh and you want solar to replace all of it, four equivalent full-sun hours gives a theoretical minimum: 600Wh ÷ 4 hours = 150W. Treat that as a starting point — cloud, panel angle, heat, shading and charging losses all reduce real-world output, so you'll want panel capacity above the theoretical minimum.
Allow for Weather, Season and Location
Before relying on that calculation, check conditions for the place and month you plan to camp. NIWA's SolarView tool shows how average sun exposure changes across New Zealand through the year — a winter trip in the South Island or high country will typically give you fewer useful charging hours, and cloudy conditions can reduce output in any region.. Add margin for weather variability, shade and less-than-ideal panel positioning.
Check Your Power Station's Solar Input Limits
Panel size is only part of the calculation. Check the power station's maximum solar input, supported voltage and current range, and connector requirements before choosing a panel — a larger panel can't deliver its full rated output if the station can't accept that input. Browse the full range in the EcoFlow solar panel collection.

Conclusion
Camping power requirements should match what you'll actually use, not the maximum capacity available. Start with the devices you'll actually run, calculate their daily Wh, then account for trip length and what you can recover from solar or vehicle charging. That way you can compare camping power solutions that fit the way you travel — whether that's a South Island road trip or a longer stint off-grid.
FAQs
How long will a 300W power station last?
A 300W rating tells you how much output the station can deliver, not how long the battery will last. Runtime comes from the battery capacity in Wh and the load you connect — for example, a 300Wh battery supplying a steady 30W device gives roughly 10 hours in a theoretical calculation before conversion losses. Add up all the devices you expect to run, then compare their combined energy use with the battery capacity.
How many watt-hours does a 12V camping fridge use per day?
A 12V compressor fridge can use a few hundred watt-hours over 24 hours, with higher consumption in hot weather or when the compressor runs more frequently. Check the fridge's measured consumption when available — frequent lid openings, freezer settings and poor ventilation can all increase daily energy use.
How do I get 230V power while camping?
Use a portable power station with a compatible 230V AC output. This lets you run suitable mains-powered camping equipment without access to a powered site. Before choosing a unit, check the appliance's required wattage against the power station's continuous and surge ratings, and confirm the power station uses the standard NZ/AU outlet configuration — particularly if buying equipment designed for another market.
How long will a 1000W power station last?
Like the 300W example, the 1000W figure tells you how much power the unit can deliver at once, not how many hours it will run. For runtime, look at the battery capacity and what you plug into it — a 1,000Wh battery powering a steady 200W load may run for roughly four to five hours once normal conversion losses come into play.
Is a 1000Wh power station enough for camping?
Often, yes, for a weekend setup built around phones, lights, a fan and moderate fridge use. The picture changes once you add overnight CPAP use, Starlink or electric cooking, as those loads can eat through 1000Wh much sooner. Solar or vehicle charging during the trip can extend the battery's effective duration across several days.
