Answer
Can the Anker SOLIX C300 run ResMed AirCurve 11 VAuto BiPAP with HumidAir humidifier?
Runs
Runs. Draw is 34 W, within the 300 W continuous output. Estimated runtime on AC: about 5.0 hr, counting about 15 W of inverter draw.
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 C300 | ResMed AirCurve 11 VAuto BiPAP with HumidAir humidifier | |
|---|---|---|
| Continuous output / running draw | 300 W | 34 W |
| Capacity / average draw | 288 Wh nameplate, 245 Wh usable | 34 W |
| Runtime on AC | 5.0 hr (34 W + about 15 W inverter draw) | |
| Nights on AC (8 hr) | 0.6 | |
| On DC, best case | 7.2 hr, 0.9 nights with the ResMed Air11 DC/DC converter in the 12 V car port (Anker lists a 12 V car output on the C300: 12 V ⎓ 10 A, 120 W, per the C300 user guide (A1722).) | |
| Sources | Station source | Appliance source |
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.

Can the Anker SOLIX C300 run ResMed AirCurve 11 VAuto BiPAP with HumidAir humidifier?
Runs. Draw is 34 W, within the 300 W continuous output. Estimated runtime on AC: about 5.0 hr, counting about 15 W of inverter draw.
How was the runtime calculated?
On AC: 288 Wh × 0.85 = 245 Wh usable, divided by (34 W + about 15 W inverter draw) = 5.0 hr. On DC with the ResMed Air11 DC/DC converter in the car port there is no inverter, so the best case is 245 Wh divided by 34 W = 7.2 hr.
Where did the numbers come from?
Product page: 288 Wh and 300 W, with 600 W surge in the headline. The FAQ says the AC outlets deliver 300 W rated and 600 W with SurgePad. Willrun treats 600 W as SurgePad, not a separate motor-start rating. Weight and cycle life were not in that text. 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.
