Best portable power station for CPAP machines, ranked by $/Wh
To run this 24-hour load profile at 85% usable AC delivery, you need a power station with at least 602 Wh of battery capacity, 64 W continuous AC output, and 115 W surge capability.
ResMed Battery Guide (Doc 198103/7, page 7) states an AirSense 10 without heated humidifier draws 11 W at 10 cm H2O (88 Wh per 8-hour night), while turning on the HumidAir heated humidifier increases typical draw to 53 W (424 Wh per 8-hour night, ResMed Clinical Guide Doc 378759/4). Disabling the heated humidifier or using a 12V DC adapter triples battery runtime. Verify reference source

Frequently asked questions
How many watt-hours does a CPAP machine use per night?
Without a heated humidifier or heated tubing, a standard CPAP machine draws about 11 W (88 Wh over 8 hours). With a heated humidifier active, typical draw rises to 53 W (424 Wh over 8 hours) with a 104 W peak warm-up draw, per ResMed technical documentation.
Why does running a CPAP on 12V DC last longer than 120V AC?
Running a CPAP from a 12V DC car port bypasses the power station AC inverter, avoiding the 10% to 15% DC-to-AC conversion overhead.
