Pick 3: Jackery Explorer 2000 v2
Best for three nights with the humidifier on
The biggest factor in how much battery your CPAP needs is the humidifier. Published estimates based on manufacturer power specs put a modern auto-CPAP at roughly 240 to 320 Wh per eight-hour night with the humidifier off, and about 440 to 560 Wh with it on, more with a heated tube in cold weather. Your own machine and pressure may land outside those ranges, and running from a DC cable instead of an AC outlet saves energy.
That means three dry nights fit a 1 kWh station, while three humid nights need around 2 kWh or a way to recharge. Decide which camp you are in, check your machine's power specs, and do a test night at home on battery before you trust it in the woods.

An estimate, not a guarantee. Run a test at home before you depend on a station, especially for medical devices. Hardwired loads like well pumps, furnaces and 240 V appliances need an electrician and a transfer switch, not an extension cord.

#1: Jackery Explorer 1000 v2
Best overall for three humidifier-off nights
Skip it if you need the humidifier on every night; it covers only about one and a half humidified nights.
For three nights with the humidifier off, a 1 kWh station is the sensible size, and the Explorer 1000 v2 has the most capacity in that class at 1,070 Wh. One published runtime table estimates two and a half to three and a half humidifier-off nights from it on AC, and a 12 V, 10 A car output lets you use a CPAP DC cable to stretch that further. It weighs about 23.8 pounds, which suits car camping and cabins. Jackery's app also offers a quiet charging mode that charges from the wall at a lower rate, roughly five hours to full, handy if you are topping it up in the room where you sleep.
Why it fits
- Most capacity in the 1 kWh class compared
- Car port for a CPAP DC cable
Watch out for
- Only about one and a half humidified nights
#2: Anker SOLIX C1000 Gen 2
Best quiet 1 kWh pick with fast top-ups
Skip it if you want the most capacity in the 1 kWh class; the Jackery holds a little more.
The C1000 Gen 2 is the other strong 1 kWh choice, with 1,024 Wh, close to the Jackery's runtime. Its edge is the bedroom: Anker rates it at 0 to 20 dB when the load is 200 W or less, which covers a CPAP. It also takes up to 600 W of solar and recharges from the wall quickly, so a sunny afternoon at camp can put a good share of a night back. It has AC outlets, a 120 W car socket for a DC cable and a 10-millisecond UPS for home outages, and it weighs about 24.9 pounds.
Why it fits
- Very quiet at CPAP-level loads
- High solar input for recharging at camp
Watch out for
- Slightly less capacity than the Explorer 1000 v2
#3: Jackery Explorer 2000 v2
Best for three nights with the humidifier on
Skip it if you have to carry it any distance from the car; it weighs nearly 40 pounds.
If you will not sleep without humidity, three nights at roughly 440 to 560 Wh each adds up to more than any 1 kWh station holds once conversion losses are counted. The Explorer 2000 v2 doubles the capacity to 2,042 Wh while staying relatively light for its class at about 39.5 pounds. It can also run other camp loads, with 2,200 W of continuous output, and it has a UPS mode that switches over in under 20 milliseconds for nights at home during an outage. It is a two-hand lift from the car, so it suits cabins and drive-in sites rather than anywhere you have to hike.
Why it fits
- Enough capacity for humidified multi-night trips
- Doubles as home outage backup
Watch out for
- Heavy at nearly 40 pounds
#4: EcoFlow RIVER 3 Plus
Best modular pick if you want to start small
Skip it if you want three nights out of the box without buying the extra battery.
The RIVER 3 Plus is a 10.4-pound, 286 Wh station, which on its own covers about one humidifier-off night for many machines. Its appeal is that EcoFlow's clip-on extra batteries stack underneath without cables, taking it as high as 858 Wh with the larger pack, close to two and a half to three dry nights, and you can carry the pieces separately. It is rated under 30 dB, and it has AC outlets plus a 12.6 V, 10 A car outlet for a DC cable. At home it works as a UPS for the CPAP during short outages, with switchover under 10 milliseconds.
Why it fits
- Light base unit; add capacity later
- Quiet, with AC and car outlets
Watch out for
- Needs the extra battery for three nights
#5: Anker SOLIX C300 DC
Best ultralight one-night pick if your CPAP runs on DC
Skip it if your CPAP needs an AC outlet, or you need more than about one night without the humidifier.
The C300 DC is the lightest way to carry nearly 300 Wh: about 6.2 pounds in a body under 8 inches tall. It is not a three-night battery on its own, but it is a good overnight or backpacking-adjacent option for humidifier-off sleep. It has no AC outlet at all, only a 12 V, 10 A car-style socket and USB-C ports, so it only makes sense if your CPAP has a manufacturer-approved DC cable or converter. It recharges from solar at up to 100 W or through two 140 W USB-C ports.
Why it fits
- Lightest station here
- DC-only design avoids inverter losses
Watch out for
- No AC outlet; about one dry night
Quick comparison
For three nights with the humidifier off, get the Jackery Explorer 1000 v2, or the Anker C1000 Gen 2 if quiet operation and fast solar top-ups matter more. For three humidified nights, step up to the Jackery Explorer 2000 v2. If you would rather start light and add capacity, the EcoFlow RIVER 3 Plus with its larger extra battery gets close to three dry nights. The Anker C300 DC is a one-night ultralight for DC-ready machines.

This is not medical advice
Talk to your sleep clinician or equipment supplier before changing how you use your CPAP, including turning off the humidifier, and use only the power accessories your CPAP manufacturer approves. If you depend on the machine, always carry a backup plan for a dead battery.
Frequently asked questions
How much battery does a CPAP need for three nights?
Published estimates put many modern machines at about 240 to 320 Wh a night with the humidifier off and 440 to 560 Wh with it on. Your machine may differ, so run a full test night on battery at home, note the percentage used, multiply by three and add a margin.
Is it better to run a CPAP from DC or AC?
DC is usually more efficient, because it avoids converting battery power to AC and back again inside your power brick. Use only the DC cable or converter your CPAP's manufacturer approves for your model.
Can I use the heated humidifier on battery?
Yes, but it roughly doubles the energy per night in published estimates. For three humidified nights, plan on a station around 2 kWh, or a 1 kWh station plus solar recharging during the day.
Can a power station act as a CPAP backup at home?
Yes. Stations with a UPS mode, like the Explorer 1000 v2, C1000 Gen 2, Explorer 2000 v2 and RIVER 3 Plus, stay plugged into the wall and switch to battery automatically if the power fails during the night.
