Questions

How long will the Goal Zero Yeti 1500X run a CPAP?

Runs. At the AirSense 11 user-guide typical of 56.1 W, usable energy is 1,289 Wh and runtime is about 23.0 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 3,500 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?

Spec list: 1,516 Wh (10.8 V, 140.4 Ah), NMC, 500 cycles to 80% at 1C, 2 AC outlets at 2,000 W and 3,500 W surge. Weight was not in the spec block that was retrieved, so it is omitted. A shelf price was not recorded as a launch price.
