For car camping with a 12 V fridge, phones and lights, the best portable power station is a 700 to 1,000 Wh unit with a 12 V car socket, solar input and a weight you can lift into the trunk. Go bigger only for AC gear like a coffee maker (about 1.5 kWh) or three days or more without sun (about 2 kWh). The picks below come from our sizing engine, run on four common camping setups, so each one shows the runtime behind it.

How much power does a camp setup use in a day?
Energy at the device for one day of typical use, from our appliance data. Running anything on AC also keeps the inverter on, which costs standby power around the clock.
| Device | Per day |
|---|---|
| 12 V fridge, 45 LFrom the 12 V socket; hot weather can double it | 324 Wh |
| Two phonesUSB charging | 40 Wh |
| Two LED bulbs on AC6 hours each, plus inverter standby below | 120 Wh |
| CPAP, no humidifier8 hours; DC cord draws less | 90 Wh |
| CPAP with humidifier and heated tube8 hours | 362 Wh |
| Drip coffee maker15 minutes of brewing | 250 Wh |
| Inverter standby, mid-size station12 W while AC is on, all day | 288 Wh |
Why USB lights beat AC lamps at camp
With the Anker SOLIX C1000 Gen 2, a 12 V fridge and two phones run about 2.3 days, because nothing uses the inverter. Add two LED bulbs on the AC outlet and the same battery lasts about 27 h. The bulbs themselves are small; the inverter's standby draw of roughly 288 Wh a day is not. Rechargeable or USB lanterns keep the inverter off, and that alone lets a smaller, lighter station do the job.
Which outlets matter for camping?
- A 12 V car socket. Portable compressor fridges plug into it. Not every station has one, so we ran the picks above only on models that do.
- USB-C at 60 W or more for a laptop, and USB-A or USB-C for phones and lanterns.
- AC outlets only for what has no DC option: a coffee maker, a CPAP without a DC cord, a TV.
Recharging at camp: solar and the car
A car's 12 V socket is usually fused at about 10 A, so it supplies roughly 100 W. That puts back about 1 kWh in ten hours of driving, enough to cover a day of fridge and phones, not much more. Run the engine while charging, so you don't drain the starter battery, and never idle a car in a closed garage.
Solar does more. A 200 W panel, which delivers about 140 W in real sun, refills 90% of the Anker SOLIX C800X / C800 Plus in about 1.2 days at 4 peak sun hours, or tops up a day of fridge and phones in a single day. Check the station's solar input limit before buying a bigger panel; anything above it is wasted.
Camping with a CPAP
Power planning for a CPAP, not medical advice. Without the humidifier, a typical machine draws about 11 W; with the humidifier and heated tube, closer to 45 W. A DC cord or converter approved by your CPAP's maker avoids the inverter and stretches runtime further. Turn off the station's ECO or auto-off mode before bed, because a low CPAP load can fall under the threshold that switches the outlet off. Talk with your doctor about going without humidification.
Weight: what you'll actually carry
A typical 1 kWh station weighs about 27 lb, an easy lift from the trunk to the picnic table. A typical 2 kWh unit weighs about 42 lb, and buying one too heavy to take along is a common owner regret. If you camp mostly in a vehicle with a big battery, the weight doesn't matter; if you carry the station to a site, pick the smallest one that covers your days.

2. The power station
What people actually ask
What size power station do I need for camping?
For a 12 V fridge and phones, about 360 Wh a day at the devices, so a 700 to 1,000 Wh unit covers a weekend when solar or the car tops it up, and about 2 kWh covers three days without recharging. Adding AC lights or a coffee maker moves you up a size, because the inverter's standby draw runs all day.
How long will a power station run a 12 V camping fridge?
A 45 L compressor fridge uses roughly 0.3 kWh a day in mild weather, so a 1,024 Wh station runs it alone for about 2.6 days from the 12 V socket. In hot weather or freezer mode it can use twice as much, which halves that.
How long does it take to charge a power station from a car?
A car's 12 V socket supplies only about 100 W, so putting back 90% of a 1,024 Wh battery takes about 9 hours of driving. Run the engine while charging so you don't drain the starter battery. Solar or an alternator charger installed in the vehicle is much faster.
Can I run a CPAP on a power station while camping?
Yes. A CPAP without the humidifier draws about 11 W, so even a 288 Wh unit runs one for about 21 h on a DC cord, or about 2 eight-hour nights. The humidifier and heated tube roughly quadruple the draw. Use the CPAP maker's approved DC cable, turn off the station's ECO or auto-off mode, and treat this as power planning, not medical advice.
Can I charge a power station in freezing weather?
Not below 32°F with LiFePO4 batteries, which most current models use; their battery management blocks charging until the cells warm up. Cold also cuts usable capacity, by about 15% around 14°F. Keep the station in the tent or car overnight, not on the ground outside.
Who should buy which
- Weekend car camping with a 12 V fridge: a 700 to 1,000 Wh unit with a 12 V socket and solar input.
- Coffee maker, TV or AC lamps at camp: step up to about 1.5 kWh, since the inverter runs all day.
- Three days or more without sun: about 2 kWh, and accept the extra weight.
- Phones, lanterns and a CPAP on DC only: a 300 Wh unit can be enough; see the small power station picks.
The bottom line
Size camping power by your fridge and your days between charges, and keep everything you can on 12 V and USB. A 700 to 1,000 Wh unit with a car socket and solar input covers most weekends; go bigger only for longer trips without sun or for AC appliances. For your own gear, the sizing quiz runs the same engine, and the runtime calculator and comparison chart fill in the details. Taking a CPAP? The what a power station can run chart shows each size class.
