ResMed AirCurve 11 VAuto BiPAP with HumidAir humidifier
ResMed AirCurve 11 VAuto BiPAP with HumidAir humidifier draws 34 W while on, and about 34 W after its published duty cycle.
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.
An 8-hour night uses about 272 Wh. Compare every CPAP and BiPAP setting on the CPAP hub.

Anker SOLIX F3800 row: uses about 40 W of idle draw instead of 15 W, because Anker's FAQ for the F3800 Plus lists about 40 W with AC on and nothing connected (Anker; F3800 idle table). The F3800 DC column uses its 12 V ⎓ 10 A car charger output (Anker US user guide), which skips the inverter. The RIVER 2, RIVER 3 Plus and SOLIX C300 DC figures use their 12 V car outputs (EcoFlow RIVER 2 manual: 100 W max; RIVER 3 Plus specs: 126 W max; Anker C300 guide: 12 V 10 A). The DELTA Pro 3 has 12 V Anderson and DC5521 outputs but no car socket, so it stays AC-only here.
How AC runtime is figured: usable Wh (nameplate × 0.85) ÷ (CPAP watts + about 15 W). The 15 W is the inverter's own draw just to stay on: BLUETTI counts about 15 W of self-consumption in its AC180 runtime formula, and an owner test measured about 17.5 W idle on a DELTA 3 Plus. Larger stations can idle higher, so test your own setup before you rely on it. DC figures skip the inverter and are a best case. Method and DC converter limits: CPAP power station guide. — means no DC figure: no 12 V car port is listed for that station in the maker specs we checked.

Questions
What number does Willrun compare to the inverter?
Running watts of 34 W must fit under continuous output. Startup watts were not published.
How is runtime calculated?
On AC: usable watt-hours (capacity × 0.85) divided by (34 W + about 15 W of inverter draw). On DC with the maker's converter there is no inverter, so the best case divides by 34 W alone.
Where did this come from?
ResMed's therapy-device power table (ResMed Deutschland, Art.-Nr. 1018528/11) lists AirCurve 11 VAuto with HumidAir at 34 Wh during operation. Energy per hour equals average watts, so the average draw is 34 W. ResMed notes the values were measured in a lab and that a local meter can differ.
