Will the EcoFlow Delta Pro Ultra run a coffee maker?

Yes — the Delta Pro Ultra runs a coffee maker comfortably

Its 7200W continuous output easily covers the 900W draw, with 21600W of surge on tap for startup.

Estimated runtime

about 5 hours

on a single full charge

Est. usable (AC): 4,701 Wh

Appliance draw: 900 W

Continuous output: 7200 W

How we calculated this

We start from the EcoFlow Delta Pro Ultra's 4,701 Wh of estimated usable energy at the outlet — its 6,144 Wh rating, derated for a safe depth of discharge and ~15% inverter loss — then divide by the coffee maker's 900W draw:

4,701 Wh ÷ 900 W ≈ 5.2 hours

Heads up: a coffee maker is a motor/compressor load that spikes 2–3× on startup. The EcoFlow Delta Pro Ultra's 7200W continuous / 21600W 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.
