How long will the EcoFlow Delta 2 run a 12v cooler / fridge?

Q: Will the EcoFlow Delta 2 run a 12v cooler / fridge?

Yes — the Delta 2 runs a 12v cooler / fridge comfortably. Its 1800W continuous output easily covers the 45W draw, with 2700W of surge on tap for startup.

Q: How long will the EcoFlow Delta 2 run a 12v cooler / fridge?

The EcoFlow Delta 2 has 1024 Wh (about 784 Wh usable at the outlet, estimated). Running a 12v cooler / fridge that draws 45W, it lasts about 17 hours on a single full charge.

Estimated runtime

about 17 hours

on a single full charge

Est. usable (AC): 784 Wh

Appliance draw: 45 W

Continuous output: 1800 W

How we calculated this

We start from the EcoFlow Delta 2's 784 Wh of estimated usable energy at the outlet — its 1,024 Wh rating, derated for a safe depth of discharge and ~15% inverter loss — then divide by the 12v cooler / fridge's 45W draw:

784 Wh ÷ 45 W ≈ 17.4 hours

Heads up: a 12v cooler / fridge is a motor/compressor load that spikes 2–3× on startup. The EcoFlow Delta 2's 1800W continuous / 2700W 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.
