Questions

How long will the Anker SOLIX C300 run a CPAP?

Runs. At the AirSense 11 user-guide typical of 56.1 W, usable energy is 245 Wh and runtime is about 4.4 hr.

What does the 0.85 factor do?

Willrun multiplies nameplate watt-hours by 0.85 before dividing by average draw. That allowance is for inverter loss. It is not a measured efficiency for this model.

Is the surge rating safe to use for a fridge or a pump?

The extra headroom on this model is SurgePad. Willrun does not treat it as locked-rotor starting capacity.

Where do the station 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.
