If you rely on a CPAP, a power outage or a camping trip shouldn’t mean a sleepless night. The right portable power station for CPAP use runs your machine for several nights, stays silent beside the bed and switches over instantly if the grid fails.
Quick answer
The Jackery Explorer 1000 v2 (1,070Wh) runs a typical CPAP without a humidifier for about 2–3 nights. For longer outages or heated-humidifier use, the Pecron E1500LFP (1,536Wh, expandable) gives much more headroom. Always confirm power requirements with your CPAP manufacturer.
How Much Power Does a CPAP Use?
Most modern CPAP machines draw about 30–60W without the heated humidifier. Turning on the humidifier and heated tubing can push that to 70–110W or more. Check your machine’s power supply label or manual for exact figures.
CPAP Runtime by Power Station Size
| Power station | CPAP only (~40W) | CPAP + humidifier (~90W) |
|---|---|---|
| 300Wh | ~6 hours (≈1 night) | ~3 hours |
| 1,000Wh | ~21 hours (≈2.5 nights) | ~9 hours (≈1 night) |
| 1,500Wh | ~32 hours (≈4 nights) | ~14 hours (≈1.5 nights) |
| 2,000Wh | ~42 hours (≈5 nights) | ~19 hours (≈2 nights) |

Tips to Extend CPAP Runtime
- Use a DC adapter made for your CPAP and plug into the 12V port. Skipping the AC inverter can add 10–20% runtime.
- Turn off the humidifier and heated tube during outages if your doctor says it’s okay.
- Use UPS mode so the CPAP switches to battery automatically if the power fails at night.
- Keep the unit charged to at least 80% during storm season.

CPAP FAQ
Can a portable power station run a CPAP all night?
Yes. Even a 300Wh unit can run a 40W CPAP for roughly one night without the humidifier. A 1,000Wh unit gives about 2–3 nights.
Is it safe to run a CPAP from a power station?
Yes, as long as the power station has a pure sine wave inverter (all our picks do) or you use the manufacturer’s DC adapter.
Do I need UPS mode for a CPAP?
It’s not required, but it’s very useful: UPS mode switches to battery instantly during an outage, so your therapy isn’t interrupted while you sleep.
