Questions
How long will the Goal Zero Yeti 500X run a CPAP?
Runs. At the AirSense 11 user-guide typical of 56.1 W, usable energy is 422 Wh and runtime is about 7.5 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?
This model publishes a surge of 1,200 W separately from any heater-only boost, so Willrun uses it when the appliance also publishes startup watts. If the appliance does not, the verdict stays a surge risk.
Where do the station numbers come from?
