Questions

How long will the EcoFlow RIVER 2 Pro run a CPAP?

Runs. At the AirSense 11 user-guide typical of 56.1 W, usable energy is 653 Wh and runtime is about 11.6 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 X-Boost. Willrun does not treat it as locked-rotor starting capacity.

Where do the station numbers come from?

Product spec: 768 Wh, pure sine wave, 800 W total (surge 1,600 W). Comparison table lists the same 1,600 W as X-Boost, 4 AC outlets, and 17.2 lb. Treated as resistive boost, not motor-start capacity.
