The short answer

Our pick at PreppedPower for running a CPAP through an outage is the Anker SOLIX C1000 Gen 2: it combines 1,024 Wh with a published 10 ms switchover. Its ≈ 15.8 h calculated runtime is slightly short of two full eight-hour nights. The Jackery is lighter; the Bluetti holds more energy. Confirm compatibility with your CPAP maker before choosing.

What CPAP needs from a power station

≈ 520 Wh

rated capacity · calculated

A reference CPAP load of 40 W, plus 15 W inverter idle, uses 440 Wh over 8 hours. Heated humidifier off. Allowing for conversion losses gives the rated capacity on the left.

Your machine and settings may draw more. Use its documentation or a power meter, and check its approved battery and adapter options. Runtime is an estimate, not a medical backup guarantee.

The maths, shown

Every runtime here is calculated from rated capacity. Here is the first pick, step by step.

1. Start with rated capacity. 1,024 Wh
2. Allow for conversion losses. × 0.85 = 870 Wh
3. Add the load and inverter idle draw. 40 + 15 = 55 W
4. Divide usable estimate by total load. ≈ 15.8 h · calculated

An estimate from rated capacity, not a measured runtime. Temperature, battery age, settings and the real load change the result.

Before you buy

DC operation avoids inverter idle consumption in our model. Use only a compatible adapter specified for your machine. Keep the station within its published charging temperature range.

Questions

How long will a station in this size tier run a CPAP?

At our reference 40 W load with 15 W AC idle, the SOLIX C1000 Gen 2 calculates to about 15.8 hours. A humidifier, temperature changes and battery age change that result.

How much battery does a CPAP need for one night?

About 520 Wh of rated capacity for eight hours at our 40 W reference with the heated humidifier off, once inverter idle and conversion losses are counted. Champion Power Equipment's wattage chart puts a CPAP at 30 to 60 W without heat and 60 to 120 W with the heated humidifier on. At those heated figures, one night needs roughly 710 to 1280 Wh. Your machine's power supply label and settings decide where you fall.

Can I use the DC port?

Check your CPAP manufacturer’s approved adapter and voltage requirements. Our DC estimate removes AC inverter idle; it does not establish adapter compatibility.

Is a fast switchover enough?

No. Confirm compatibility and backup arrangements with the CPAP manufacturer. A published switchover specification is not a guarantee that a particular medical device will keep operating.

Are these runtimes measured?

No. They are calculated from rated capacity, based on manufacturer specs and published third-party measurements of how much of that capacity reaches the outlet. In independent load-bank tests, OutdoorGearLab found stations delivered 75 to 93 percent of their rated capacity as AC power, and small overnight loads like a CPAP sit at the low end because inverter idle draw takes a bigger share.

Can I take one of these power stations on a plane for my CPAP?

No. The FAA allows spare lithium batteries up to 100 Wh in carry-on bags, and 101 to 160 Wh only with airline approval. Every station on this page is far above that. For travel, use a battery your CPAP manufacturer approves for flying.
