Questions
How long will the EcoFlow DELTA Pro 3 run a CPAP?
Runs. At the AirSense 11 user-guide typical of 56.1 W, usable energy is 3,482 Wh and runtime is about 2.6 days.
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 8,000 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 block: 4,096 Wh, AC continuous 4,000 W and 6,000 W with X-Boost, AC surge 8,000 W, 51.5 kg (113.54 lb), LFP, 4,000 cycles to 80%.
