Model-Specific Results
3 of 3 models are SAFE or TIGHT. Most demanding model: ResMed AirSense 10 AutoSet (104W surge).
| Model | Running | Surge | Verdict | Runtime | Source |
|---|---|---|---|---|---|
| ResMed AirSense 11 AutoSet | 56.1W | 73.2W | Safe | ~47.9h | OEM Manual |
Show expert analysisTechnical: **Running load:** 56.1 W typical. **Surge:** 73.2 W peak. **Voltage:** 120 V AC. The machine draws continuous low power with minimal startup spike. Most portable power stations with 120V inverters and 100+ W output handle this load comfortably. Field note: Verify your power station provides stable 120V AC output and at least 75W continuous rating. Disable the heated humidifier to reduce draw by ~30% and extend runtime. Always carry a backup power source for life-critical equipment. Can I run the AirSense 11 on a 500Wh power station? Yes — at 56.1W typical, a 500Wh station (350Wh usable) provides roughly 6 hours. Disabling the humidifier drops draw to ~40W and extends runtime to a full night. | |||||
| ResMed AirSense 10 AutoSet | 53W | 104W | Safe | ~50.7h | OEM Manual |
Show expert analysisTechnical: **Running load:** 53 W typical. **Surge:** 104 W peak. **Voltage:** 120 V AC required. The AirSense 10 has a higher peak draw than the newer AirSense 11 due to its older motor design. Field note: The 104W peak is the sizing constraint. Ensure your power station can handle at least 120W continuous to cover the startup surge with margin. Use a pure sine wave inverter — modified sine wave may cause motor faults in medical devices. Can I use a portable power station rated for 100W continuous? Risky — the AirSense 10 peaks at 104W. A station rated at exactly 100W may trip on startup. Look for 150W+ continuous rating to be safe. | |||||
| Fisher & Paykel SleepStyle Auto | 39W | 76W | Safe | ~68.9h | Engineering Est. |
Show expert analysisTechnical: **Running load:** 39 W typical. **Surge:** 76 W peak. **Voltage:** 120 V AC required. The SleepStyle has an integrated power supply (no external brick) and built-in heated humidifier. The 39W figure includes the humidifier at typical settings. Field note: The SleepStyle is the most power-efficient full-size CPAP here. At 39W typical, even a compact 500Wh power station covers a full night with margin. The integrated humidifier means no separate heater to add to the load. Is the Fisher & Paykel SleepStyle easier to run off-grid than ResMed? Yes — at 39W typical vs 53-56W for ResMed models, the SleepStyle draws roughly 30% less power. An 8-hour night consumes ~312 Wh vs 424-449 Wh for ResMed. | |||||

Generator Insights
The 9000W surge rating can handle typical compressor-based appliances like central air conditioners, well pumps, and refrigerators during startup. This capacity can support multiple simultaneous high-draw devices once running loads stabilize. Expect reliable operation for tools, HVAC systems, and other inductive loads that demand short-duration power spikes.
This unit employs LFP chemistry with a 3840Wh capacity, designed for stable discharge under high-demand conditions. The architecture supports both sustained and transient loads within rated limits. Source: Anker SOLIX F3800 User Manual v1.1 (Specifications) (OEM documentation).

Technical Analysis
Spec-Based • No GuaranteesTechnical Breakdown
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.
Expected Behavior
Estimated runtime: ~47.9h. 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.
Field Note
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
Can the Anker SOLIX F3800 power a CPAP Machine?
Yes. The Anker SOLIX F3800 provides 6000W running / 9000W surge. The CPAP Machine needs 65W / 120W (including 15% buffer). That leaves 5935W of running headroom and 8880W of surge margin.
How long will the Anker SOLIX F3800 run a CPAP Machine?
Approximately 47.9 hours, based on the CPAP Machine's 56W draw and the Anker SOLIX F3800's 3840Wh capacity (70% usable after real-world losses).
What Else Can You Run?
With 425W allocated to the CPAP Machine, the Anker SOLIX F3800 still has ~4319W of margin. These devices could run simultaneously:
