Camping power comes down to one number: how many watt-hours you use between charges. Everything else, the box you buy, the panel you add, whether you need a generator at all, follows from that. A weekend of phones, lights and a CPAP is roughly 300–400 Wh. Add a 12V cooler and it climbs past 1,000 Wh. This camping power guide walks through how to size it, what each option costs you in weight and money, and which of our detailed posts to read next.
WildJoule verdict
Most campers need 250–300 Wh for a weekend of phones, lights and a CPAP, 700–800 Wh once a 12V fridge comes along, and 1 kWh or more only for cooking or week-long stays. Buy LiFePO4 for the cycle life, add a foldable panel only if you stay put for more than two nights, and skip a generator unless campground rules and noise genuinely allow one.
Plain admission: I don’t own the units below and I haven’t camped with them. What I do is read the spec sheets, work the runtime math and compare it against what campers actually carry. Needing a few things to keep running when the mains drops out is familiar to me, so I lean toward small, dependable setups over big ones that sit unused.
Camping power options compared
| Option | Typical capacity | Best for | Main drawback |
|---|---|---|---|
| Small power station (Anker SOLIX C300, EcoFlow River 3) | 245–288 Wh | Phones, lights, laptop, CPAP, 2–3 nights | Won’t run a fridge for more than about 6 hours |
| Mid power station (Bluetti AC70) | 768 Wh | 12V fridge, longer trips | About 22.5 lb |
| Large power station (1 kWh class) | 1,000+ Wh | Cooking, week-long stays | Weight and cost for a car-camping load |
| Portable solar panel | 100–200 W | Refilling over a sunny day | Needs sun and setup; slow on cloudy days |
| Gas generator | Fuel-limited | Heavy loads, long runs | Noise, fumes, campground rules |
Capacities and weights are manufacturer-stated; fridge and CPAP figures later in this guide are our estimates.
How to size camping power in watt-hours
List each device, multiply its watts by the hours you run it, and add 20% for inverter losses. A phone charge is about 15 Wh, a laptop battery around 60 Wh, a CPAP roughly 30 W, and a 12V compressor cooler near 40 W averaged over a day (assumption; it varies with heat and how often you open it). Our camping power calculator does the arithmetic, and watt-hours explained covers the units.
Two things inflate the total faster than anything else: heating and cooling. Heated blankets, space heaters and induction cooktops can empty a 288 Wh unit in hours, so decide early whether you are cooking on gas or on a battery.
Picking a power station for camping power
For car camping, small units win on weight. The Anker SOLIX C300 stores 288 Wh, outputs 300 W and has a 140 W USB-C port, while the EcoFlow River 3 holds 245 Wh at 7.8 lb. We rank them with three bigger options in best power station car camping, and compare the first two directly in River 3 vs Anker C300.
For tent camping you carry the box farther, so weight matters more; see how to use a power station while tent camping. If a CPAP is the main load, start with best power station for CPAP.
When a bigger camping power setup makes sense
The Bluetti AC70 is listed at 768 Wh with 1,000 W output and a 20 ms UPS switch. By our math it runs a 40 W cooler for about 16 hours and a CPAP for close to a full day. That is the size to consider for a long weekend with a fridge, but at about 22.5 lb it lives in the car. If your budget is the limiter, see best power station under 500 dollars; if you plan to cook, step up to the 1 kWh class covered in best power station under 1000 dollars.
Solar for camping power: when it pays off
A panel pays off when you stay put for more than two nights and have clear sun. A 100 W foldable panel in good sun yields a few hundred watt-hours a day, which roughly refills a small station. In shade or on cloudy days the yield drops sharply. If you want a suitcase-style panel, see our Renogy 200W suitcase review and Bluetti PV350 review. For trips under two nights, start full and skip the panel.
Cold weather, safety and campground rules
Cold hurts batteries: most LiFePO4 units limit or block charging below freezing, so keep the station inside your sleeping area or insulated bag on cold nights. Read power station in cold weather before a winter trip.
Never run a gas generator near a tent or vehicle cabin, and check the campground’s generator rules. The National Park Service and many private campgrounds limit generator hours or ban them, which is one practical reason batteries suit camping power. For fundamentals, our complete portable power station guide and buying guide explain the specs that matter.

Frequently asked questions
How much camping power do I need for a weekend?
About 250–400 Wh covers phones, lights, a laptop and a CPAP. Add a 12V fridge and plan for 700 Wh or more.
Is solar worth it for camping?
Yes for stays of three nights or more with open sun. For one or two nights, start with a full battery instead.
Can a power station run a camping fridge?
A 12V compressor cooler averages roughly 40 W in our estimate, so a 768 Wh unit runs one for about 16 hours; a 288 Wh unit about six.
What is better for camping, a generator or a power station?
A power station is silent and fume-free and suits most campers. A generator only makes sense for heavy loads or long off-grid stays where rules allow it.
