What to Know About the CPAP Machine
Power Profile
Running range: 39W (F&P SleepStyle) to 56.1W (ResMed AirSense 11) typical. Peak surge: 104W (ResMed AirSense 10 startup). Voltage: 120V AC. CPAP machines are low-draw medical devices — the startup surge is the sizing constraint, not the running watts.
Real-World Usage
An 8-hour sleep session consumes 312-449 Wh depending on model, pressure settings, and humidifier use. Load is steady after initial pressurization with minor fluctuations during the breath cycle.
Pro Tip
Use a pure sine wave power station — modified sine wave inverters may cause motor faults in medical devices. Disable the heated humidifier to reduce draw by ~30% and extend runtime. Always carry a backup power source for life-critical equipment.

Frequently Asked Questions
How many power stations can run a CPAP Machine?
Out of 33 portable power stations we tested, 33 can safely run a CPAP Machine (33 with full safety margin, 0 at tight margin). 0 are incompatible.
What specs should I look for to run a CPAP Machine?
Your power station needs at least 56.1W continuous output and 104W surge capacity. We recommend a safety buffer of 15% above these minimums for reliable operation.
How do we test compatibility?
Every pairing is evaluated using our True Surge protocol: we compare OEM-verified running watts, surge watts, and voltage requirements against each power station's published specs, with load-profile-specific safety buffers applied. Read our full methodology.
What size power station do I need for a CPAP machine?
Only if your power source can supply at least 56W continuous and 104W surge at 120V. A 500Wh station provides roughly 6 hours at worst-case draw (56W). For a full 8-hour night with margin, look for at least 700Wh. Disabling the humidifier extends runtime further.
