EcoFlow describes the 600 W figure as surge with X-Boost. Willrun treats it as a resistive boost, not motor-start capacity. The manual language for X-Boost says it suits heating devices. |

Questions
How long will the EcoFlow RIVER 2 run a CPAP?
Runs. At the AirSense 11 user-guide typical of 56.1 W, usable energy is 218 Wh and runtime is about 3.9 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?
US/CA comparison table: 256 Wh, 2 AC outlets at 300 W, X-Boost 600 W, 7.7 lb, LiFePO4, 3,000 cycles to 80%+. EcoFlow describes the 600 W figure as surge with X-Boost. Willrun treats it as a resistive boost, not motor-start capacity. The manual language for X-Boost says it suits heating devices.
