Camping Power Station Size Guide: How Many Watt-Hours Do You Actually Need?
One of the most common questions we hear from outdoor buyers is: "How big a power station do I need for camping?" Buy too small and you run out of power on night two. Buy too big and you pay for capacity you never use. This guide breaks it down by scenario, with real numbers.
Step 1: List What You Actually Plug In
Every device has a wattage rating (W). Multiply watts by hours of use to get watt-hours (Wh) consumed per day:
| Device | Typical Wattage | Hours / Night | Wh Used |
|---|---|---|---|
| Smartphone (recharge) | 20W | 1h | ~20Wh |
| LED camp light string | 10W | 5h | ~50Wh |
| Drone batteries (3x) | 60W | 1.5h | ~90Wh |
| Camera batteries + laptop | 65W | 3h | ~195Wh |
| Portable fridge-freezer (45L) | 45W avg | 10h | ~450Wh |
| CPAP machine | 40W | 8h | ~320Wh |
| Electric cooler + fan | 70W avg | 8h | ~560Wh |
Add roughly 15% overhead for inverter losses, and you have your daily Wh target.
Step 2: Match Capacity to Camping Style
Light & Minimal (under 100Wh/day)
Phone charging, LED lights, a speaker, drone top-ups. A compact unit is plenty:
- A1 200W / 145Wh — pocketable, weighs almost nothing, built-in LED light for the tent.
- A3B 300W / 288Wh — wireless charging pad on top, SOS light, and a 24V DC5525 output for 12V camping gear.
Weekend Car Camping (300–600Wh/day)
You are running a small fridge, camera gear, and lights for two nights:
- A5 500W / 520Wh — a full weekend of essentials in a 6kg-class body.
- A6 600W / 520Wh — same capacity with wireless charging and LED lighting built in.
Family Camping with Fridge (600–1200Wh/day)
A 45L fridge-freezer alone eats ~450Wh a day. Add cooking prep, fans, and kids' devices and you want headroom:
- T11 1200W / 1008Wh — runs a fridge for a full weekend plus lights and devices.
- C15 1500W / 1008Wh — same capacity, higher surge for blenders and electric pumps, with an integrated LED work light.
Basecamp & Overlanding (1200Wh+/day)
Multi-day trips, 12V fridges, induction cooking, project lighting:
- C18 1800W / 1680Wh and C20 1800W / 2016Wh — two nights of fridge + cooking without recharging.
- T20 2400W / 2016Wh — adds UPS backup behavior and 2400W output for heavier appliances.
Step 3: Plan Your Recharging
Capacity is only half the story. If your trip lasts more than two days, pair the station with a solar panel. As a rule of thumb, a 100W panel yields 300–500Wh per sunny day, which keeps a 500–1000Wh system topped up indefinitely. See our solar panel pairing guide for exact matching.
Quick Answer
- Tent camping, lights + phones: 150–300Wh
- Weekend + small fridge: 500–600Wh
- Full fridge weekend: 1000Wh
- Multi-day basecamp: 1600–2000Wh+
All Heding Power stations use LiFePO4 cells rated for 3000+ cycles, so the unit you buy for this season's camping trips should still be running a decade from now. Browse the full lineup →
