Best Power Station for CPAP Machines (2025)
Keep your CPAP running while camping or during outages. We tested power stations with real CPAP machines to find the best options.
Quick Answer
Most CPAP machines use 30-60 watts per hour (up to 100W with heated humidifier). For one night of sleep, you need around 250-500Wh. For a weekend camping trip, get 500-1000Wh.

Best Overall: EcoFlow Delta 2 — $399
If you want the most flexibility, the Delta 2 handles CPAP plus everything else. Run your CPAP, charge your phone, and power a mini fridge—all at once.
Why it works for CPAP:
- 1024Wh for 5-7 nights of CPAP
- 1800W output powers any CPAP setup
- Recharges to 80% in 50 minutes
- Expandable to 3kWh with extra batteries
Runtime estimate: 25-34 hours at 35W (5+ nights)
CPAP Power Math
Here’s how to calculate your needs:
Step 1: Find your CPAP’s wattage
- Check the label on your machine or manual
- ResMed AirSense 10: 30-60W
- Philips DreamStation: 35-65W
- With heated humidifier: add 30-50W
- With heated tube: add 15-25W
Step 2: Calculate nightly usage
- Wattage × hours of sleep = Wh needed
- Example: 40W × 8 hours = 320Wh per night
Step 3: Add 20% buffer
- Power stations lose efficiency during conversion
- 320Wh × 1.2 = 384Wh minimum for one night
Quick reference:
| CPAP Setup | Wattage | One Night | Weekend | Week |
|---|---|---|---|---|
| CPAP only | 30-40W | 250-320Wh | 500-640Wh | 1750-2240Wh |
| With humidifier | 50-70W | 400-560Wh | 800-1120Wh | 2800-3920Wh |
| With humidifier + heated tube | 70-100W | 560-800Wh | 1120-1600Wh | 3920-5600Wh |
Tips for Maximizing CPAP Runtime
Turn off the humidifier. This alone can cut power consumption by 30-50%. Use a moisture-wicking mask liner instead.
Lower the pressure ramp. The ramp-up period uses more power than steady operation.
Use a DC adapter. Many CPAP brands sell DC-to-DC adapters that bypass the inverter, improving efficiency by 10-20%.
Charge with solar. For trips longer than a few days, pair your power station with a solar panel for unlimited runtime.
What About Dedicated CPAP Batteries?
Brands like ResMed and Philips sell purpose-built CPAP batteries. They work, but they’re expensive ($200-400) and only power your CPAP—nothing else.
A portable power station at the same price gives you:
- More capacity
- Multiple devices (phone, laptop, lights)
- Longer lifespan
- Versatility for non-CPAP uses
The only advantage of dedicated CPAP batteries is size—they’re smaller and lighter. If every ounce matters, consider them. Otherwise, a power station is the better investment.
