How long will the EcoFlow Delta Pro run a cpap machine?

Q: Will the EcoFlow Delta Pro run a cpap machine?

Yes — the Delta Pro runs a cpap machine comfortably. Its 3600W continuous output easily covers the 40W draw, with 7200W of surge on tap for startup.

Q: How long will the EcoFlow Delta Pro run a cpap machine?

The EcoFlow Delta Pro has 3600 Wh (about 2754 Wh usable at the outlet, estimated). Running a cpap machine that draws 40W, it lasts about 2.9 days (~69 hours) on a single full charge.

Yes — the Delta Pro runs a cpap machine comfortably

Its 3600W continuous output easily covers the 40W draw, with 7200W of surge on tap for startup.

Estimated runtime

about 2.9 days (~69 hours)

on a single full charge

Est. usable (AC): 2,754 Wh

Appliance draw: 40 W

Continuous output: 3600 W

How we calculated this

We start from the EcoFlow Delta Pro's 2,754 Wh of estimated usable energy at the outlet — its 3,600 Wh rating, derated for a safe depth of discharge and ~15% inverter loss — then divide by the cpap machine's 40W draw:

2,754 Wh ÷ 40 W ≈ 68.9 hours

Heads up: a cpap machine is a motor/compressor load that spikes 2–3× on startup. The EcoFlow Delta Pro's 3600W continuous / 7200W surge output has plenty of headroom for that spike.

Real-world runtime varies with temperature, cable losses, and how hard the appliance actually cycles. Treat this as a solid estimate, not a guarantee.
