Answer
Can the Anker SOLIX F3800 run ResMed AirSense 11 AutoSet, no humidifier?
Runs
Runs. Draw is 7 W, within the 6,000 W continuous output. Estimated runtime on AC: about 2.9 days, counting the about 40 W idle draw Anker lists.
Medical safety notice: Will It Run? gives general power estimates only, not medical advice. Power draw varies by model, settings, pressure, humidifier and altitude. Before relying on any battery, power station, inverter or generator for a medical device, confirm approved power sources with the device manufacturer and your doctor or equipment supplier, and test your setup before an emergency. Never change prescribed settings to extend battery life. If your therapy is life-sustaining, keep the backup your supplier provides, register with your utility's medical-needs program, and have an evacuation plan. Run generators outdoors only, at least 20 ft from windows and doors, because of carbon monoxide risk. In an emergency, call 911.

The comparison
| Anker SOLIX F3800 | ResMed AirSense 11 AutoSet, no humidifier | |
|---|---|---|
| Continuous output / running draw | 6,000 W | 7 W |
| Capacity / average draw | 3,840 Wh nameplate, 3,264 Wh usable | 7 W |
| Runtime on AC | 2.9 days (7 W + about 40 W idle draw, per Anker) | |
| Nights on AC (8 hr) | 8.7 | |
| On DC, best case | 19.4 days, 58.3 nights with the ResMed Air11 DC/DC converter in the 12 V car port (Anker lists a 12 V ⎓ 10 A car charger output on both the F3800 and F3800 Plus: US user guide.) | |

How AC runtime is figured: usable Wh (nameplate × 0.85) ÷ (CPAP watts + about 40 W). Willrun uses about 15 W of inverter draw for most stations, but Anker's own FAQ for the F3800 Plus says the unit draws about 40 W with AC on and nothing connected (Anker SOLIX F3800 Plus page, FAQ), so this page uses 40 W. At CPAP-sized loads the inverter's own draw is about as big as the machine. Test your own unit before you rely on it. Anker lists a 12 V ⎓ 10 A car charger output, so a ResMed DC converter, where it applies, skips the inverter and its 40 W entirely (see the DC row).

Questions
Can the Anker SOLIX F3800 run ResMed AirSense 11 AutoSet, no humidifier?
Runs. Draw is 7 W, within the 6,000 W continuous output. Estimated runtime on AC: about 2.9 days, counting the about 40 W idle draw Anker lists.
How was the runtime calculated?
On AC: 3,840 Wh × 0.85 = 3,264 Wh usable, divided by (7 W + about 40 W idle draw, per Anker) = 2.9 days. On DC with the ResMed Air11 DC/DC converter in the car port there is no inverter, so the best case is 3,264 Wh divided by 7 W = 19.4 days.
Where did the numbers come from?
Tech specs: 3,840 Wh, LFP with 3,000+ cycles, 6,000 W continuous at 120 V and 240 V, 9,000 W AC surge, net weight 132.3 lb including the wheel dimension noted on the page. ResMed's therapy-device power table lists AirSense 11 AutoSet operation at 7 Wh and standby at 2 Wh. The operation figure is energy per hour, so the average draw is 7 W. ResMed notes the values were measured in a lab and that a local meter can differ.
