Best Power Station for CPAP Machines: Sleep Anywhere Off-Grid
Updated January 12, 2026
If you use a CPAP machine, losing power means losing sleep — and that’s not an option. Whether you’re camping, traveling in an RV, or preparing for outages, a portable power station keeps your CPAP running all night.
How Much Power Does a CPAP Use?
CPAP power draw varies by model, pressure settings, and whether you use a heated humidifier:
| CPAP Mode | Watts | 8-Hour Night |
|---|---|---|
| CPAP without humidifier | 30-40W | 240-320 Wh |
| CPAP with humidifier (low) | 50-60W | 400-480 Wh |
| CPAP with humidifier (high) | 70-90W | 560-720 Wh |
| BiPAP / high pressure | 60-80W | 480-640 Wh |
For most CPAP users, plan on 300-500Wh per night.
Our Top CPAP Power Station Picks
Best Overall: Anker SOLIX C1000 ($699)
The Anker SOLIX C1000 at 1,056Wh gives you 2-3 nights of CPAP use without recharging (without humidifier) or 1-2 nights with a humidifier.
- 58-minute charge means last-minute prep is easy

- LiFePO4 battery lasts 3,000+ cycles
Best Budget: Bluetti AC70 ($499)
The Bluetti AC70 at 768Wh handles 1-2 nights of CPAP use. It’s the most affordable LiFePO4 option that reliably runs a CPAP.
- $499 price point is accessible
- 22.5 lbs — lightest option that still powers CPAP all night
- 45-minute 80% charge
Best for Extended Trips: EcoFlow DELTA 3 Plus ($649)
The EcoFlow DELTA 3 Plus at 1,024Wh offers 2-3 nights per charge plus expandability to 5kWh for week-long trips.
- Expandable — add batteries for 5+ nights per charge
- UPS functionality prevents any power gap when switching sources
- 56-minute charge time
Best Ultraportable: EcoFlow RIVER 3 ($199)
The EcoFlow RIVER 3 at 245Wh handles 1 night of CPAP use (without humidifier only). At 7.8 lbs, it’s the lightest option.
- Only 7.8 lbs — fits in a carry-on

- Best for single-night trips where weight matters
Tips for CPAP Users
1. Use DC power when possible. Many CPAP machines accept 12V or 24V DC input. Using DC avoids the inverter conversion, saving 10-15% battery life. Check if your CPAP manufacturer sells a DC adapter.
2. Skip the heated humidifier when camping. The humidifier can double your power draw. Use a heat moisture exchanger (HME) filter instead — it’s passive and uses zero power.
3. Lower your pressure if your doctor allows. Higher pressures draw more watts. Talk to your sleep doctor about whether a lower setting is appropriate for travel.
4. Add solar panels for multi-day trips. A 100-200W solar panel can replenish 300-600Wh per day — enough to offset one night of CPAP use and keep you going indefinitely.
5. Test at home first. Before relying on a power station for medical equipment, test it at home for a full night. Make sure the power station’s fan noise doesn’t interfere with your sleep.
What About Airline Travel?
Power stations over 100Wh are not allowed in airplane carry-on or checked baggage (FAA regulation). The only exception is the Jackery Explorer 100 Plus at 99Wh — but it has no AC outlets and can’t power a CPAP.
For air travel with CPAP, your best option is a CPAP-specific battery pack (like the Medistrom Pilot-24) that’s designed for airline use. Use a power station for road trips and camping instead.
The Bottom Line
For most CPAP users, the Anker SOLIX C1000 ($699) offers the best balance of capacity, charging speed, and price. If you camp frequently and want to expand later, the EcoFlow DELTA 3 Plus ($649) is the smarter long-term investment.
