Will the EcoFlow Delta Pro 3 run a full-size fridge?

Yes — the Delta Pro 3 runs a full-size fridge comfortably

Its 4000W continuous output easily covers the 150W draw, with 8000W of surge on tap for startup.

Estimated runtime

about 21 hours

on a single full charge

Est. usable (AC): 3,133 Wh

Appliance draw: 150 W

Continuous output: 4000 W

How we calculated this

We start from the EcoFlow Delta Pro 3's 3,133 Wh of estimated usable energy at the outlet — its 4,096 Wh rating, derated for a safe depth of discharge and ~15% inverter loss — then divide by the full-size fridge's 150W draw:

3,133 Wh ÷ 150 W ≈ 20.9 hours

Heads up: a full-size fridge is a motor/compressor load that spikes 2–3× on startup. The EcoFlow Delta Pro 3's 4000W continuous / 8000W 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.
