Runtime = usable capacity ÷ average draw. "(est.)" means no independent capacity test exists, so we assume 80% of rated capacity reaches the AC outlets. See the methodology. "Check price" links may be affiliate links.

What size do you need?

What size power station do I need for a CPAP with heated humidifier?

Look for at least 90 W of continuous AC output and 90 W of surge. For capacity, a CPAP with heated humidifier averages about 90 W, so 8 hours needs roughly 900 Wh of rated capacity and 24 hours roughly 2,700 Wh, assuming 80% of rated capacity reaches the outlets.

How long will a 1,000 Wh power station run a CPAP with heated humidifier?

About 8.9 h, if its inverter can handle the 90 W startup surge: roughly 800 Wh reaches the outlets, divided by an average draw of 90 W.

Which power station can run a CPAP with heated humidifier for a full day?

Of the 15 models we track, the smallest that runs a CPAP with heated humidifier for 24 hours on one charge is the Anker SOLIX F3800. Larger models run it longer; see the table above.
