979 Wh usable: about 18 hours at 55 W, and 9.8 hours even at 100 W, the top of the humidifier-on range.

All 37 power stations Amazon sells, ranked by cost per night
Cost per night is the Amazon price divided by the nights one charge runs a CPAP with the heated humidifier on. A lower number means more nights for your money. 33 of the 37 run at least one full 8-hour night; 26 run two or more. The cheapest to buy, the BLUETTI AC180, is number 8: bigger units cost more up front but less per night.

Nights = usable battery ÷ (watts × 8 hours), rounded down. Usable battery is 85% of the label figure. Humidifier on: 55 W, the middle of the 30–100 W range a CPAP with a heated humidifier draws, on the AC outlet. Humidifier off: 11.2 W, ResMed’s figure for an AirSense 10 on 12 V DC. How we got each number.

The 1,024 Wh units (870 Wh usable) fall just short: about 1.9 nights, so we do not count them.
How we got each number: AC, DC and the humidifier
The humidifier decides most of it
A CPAP with its heated humidifier and heated tube draws 30 to 100 W. We rank on the middle of that range, 55 W, the same figure our CPAP power page uses. ResMed gives 56.1 W as the AirSense 11’s typical draw (AirSense 11 user guide), close to it. One 8-hour night at 55 W uses about 438 Wh.
Why the AC outlet costs you about 15%
A power station stores DC power. Its AC outlets run it through an inverter, which loses some as heat. So we count 85% of the label figure as usable on AC, the same on every page of this site. Anker uses the same figure: “These estimates assume approximately 85 percent usable energy for AC loads.” (Anker SOLIX).
Why DC goes further
ResMed recommends a DC-to-DC converter over an inverter (ResMed battery guide). Its table gives the AirSense 10 with no humidifier at 0.93 A on 12 V at 10 cm H2O: 11.2 W, measured at the battery, so the converter’s loss is already in it. On DC there is no inverter, so a station gives back more than 85%. No station maker publishes a DC figure, so we keep 85% for DC too. Treat the DC nights as a floor.
You need ResMed’s Air10 DC/DC converter (part 37297) and a cable from the station’s 12 V car outlet. Most stations have one; check yours. ResMed’s figure rises with pressure: 0.7 A at 6 cm and 1.66 A at 20 cm.
Humidifier off on AC
We give no AC figure with the humidifier off. A CPAP alone draws so little that the inverter’s own running draw can match it, and makers do not publish that draw. Use DC.
What goes wrong, and how to avoid it
- The station turns itself off at night. Many stations switch off an outlet when the draw is small, to save power. A CPAP can look like nothing to it. Find the auto-off or energy-saving setting and turn it off. Then test a whole night before you rely on it.
- The battery runs out early. A heated tube on high, a high pressure or a cold room pushes the draw toward 100 W. At 100 W, the BLUETTI AC180 lasts about 9.8 hours.
- It does not switch over by itself. Plugged in between the wall and the CPAP, most stations pass wall power through and switch to battery when it fails. None we know of promise a no-break switch. Test it by pulling the plug in the daytime.
- Wrong machine settings for a battery. Ask your equipment supplier which settings and which DC cable fit your machine.
This sizes equipment. It is not medical advice and no result here promises therapy through an outage. If losing therapy overnight is a health risk, talk to your equipment supplier, and tell your utility you need medical-priority restoration.
Who should buy which
- Cheapest full night: the BLUETTI AC180, $499.
- Most nights for the money: the PECRON F3000LFP, $152 a night (5.9 nights).
- Camping, lightest that runs a full night (of the units whose maker lists a weight): the Goal Zero Yeti 700, 20.3 lb (9.2 kg), 1.3 nights, $700.
- Want a big brand and help choosing between three: our CPAP power station guide picks for one night and for three, sized at the top of the range.
- Humidifier off and on DC: nearly any of them runs many nights; pick by price and weight.
Questions people ask
What is the best portable power station for a CPAP?
For the least money that still runs a full night with the heated humidifier on, the BLUETTI AC180 ($499 on Amazon, checked October 12, 2026): about 2.2 nights per charge at 55 W. For the most nights per dollar, the PECRON F3000LFP at $152 a night.
What is the best power station for CPAP camping?
Of the units whose maker lists a weight, the lightest that runs a full night with the humidifier on is the Goal Zero Yeti 700 (20.3 lb (9.2 kg)): about 1.3 nights, $700. With the humidifier off on DC (11.2 W), even a 435 Wh unit like the OUKITEL P800 runs about 4.8 nights.
What size portable power station do I need for a CPAP machine?
For one 8-hour night with the heated humidifier on, about 438 usable watt-hours: a station rated about 516 Wh or more. At the top of the range (100 W) you need 800 usable Wh, about a 1,000 Wh station.
How many nights will a power station run a CPAP?
Usable watt-hours divided by the CPAP's watts times 8 hours. A 1,024 Wh station runs about 1.9 nights with the humidifier on (55 W) and about 9.7 nights with it off on DC (11.2 W).
Is it better to run a CPAP on DC or AC from a power station?
DC. ResMed recommends a DC-to-DC converter over an inverter. On AC the inverter loses about 15% of the battery; on DC that loss is gone.
Can a power station run a CPAP all night?
Yes, if it holds at least 438 usable watt-hours for the humidifier-on case. 33 of the 37 stations Amazon sells do. The cheapest is the BLUETTI AC180.
