Questions

How long will the EcoFlow DELTA 3 run a CPAP?

Runs. At the AirSense 11 user-guide typical of 56.1 W, usable energy is 870 Wh and runtime is about 15.5 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 3,600 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?

US spec table: 1,024 Wh, 6 outlets, 1,800 W (surge 3,600 W), X-Boost 2,200 W, 27.6 lb, LFP, 4,000 cycles to 80%+. A sale price on the page was not recorded as a launch price.
