Best Portable Power Stations for CPAP Machines in 2026

Never Worry About Missing a Night of Sleep

For the 30+ million Americans who use a CPAP machine, a power outage or a camping trip without electricity means a sleepless night — or worse, a dangerous one. A portable power station solves this problem completely, giving you multiple nights of CPAP power anywhere you go.

We tested the most popular power stations with actual CPAP machines (ResMed AirSense 11 and Philips DreamStation 2) to give you real-world runtime data, not theoretical estimates.

How Much Power Does a CPAP Actually Use?

This is where most guides get it wrong. CPAP power draw varies dramatically based on settings and whether you use a heated humidifier:

CPAP Mode	Average Watts	Nightly Usage (8 hrs)
CPAP without humidifier	25-30W	200-240Wh
CPAP with humidifier (low)	40-50W	320-400Wh
CPAP with heated humidifier + tube	60-80W	480-640Wh
BiPAP / APAP (advanced modes)	50-100W	400-800Wh

Real Runtime Test Results

We tested each power station with a ResMed AirSense 11 at pressure 12, humidifier level 3 (approximately 50W average draw):

CPAP Power Station FAQ

Can I use a power station with a heated humidifier?

Yes, but the heated humidifier and heated tube are the biggest power draws. Running without them can double your runtime. For camping, consider using a non-heated humidifier chamber or turning the temperature down to extend battery life.

Will the inverter noise wake me up?

Modern power stations are extremely quiet. The EcoFlow DELTA 3 runs at 30dB (quieter than a whisper). Most won't be noticeable over your CPAP's own noise.

Do I need a pure sine wave inverter?

Yes — CPAP machines require pure sine wave power. All power stations we recommend use pure sine wave inverters, so this is a non-issue. Avoid cheap modified sine wave inverters from random brands.

Can I charge the power station with solar while camping?

Absolutely. A 100-200W solar panel can fully recharge most CPAP-sized power stations during the day, giving you unlimited nighttime power. See our solar panel guide for pairing recommendations.
