Can the Anker SOLIX C300 run ResMed AirSense 11, typical power from the user guide?

Runs. Running draw 56.1 W is within 300 W continuous, and the published peak of 73.2 W is within 300 W. Estimated runtime: about 4.4 hr.

What watts were compared?

Station continuous output is 300 W. No motor-surge rating is applied. Appliance running draw is 56.1 W. Published appliance peak is 73.2 W.

How was the runtime calculated?

288 Wh × 0.85 = 245 Wh usable, divided by 56.1 W average draw.

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. Americas user guide, 65 W power supply section: typical power consumption 56.1 W (111.5 VA) and peak power consumption 73.2 W (137.6 VA). This is the published system figure, not the lower no-humidifier row on ResMed's separate therapy-power sheet.
