How long will the DJI Power 500 run a 12v cooler / fridge?

Q: Will the DJI Power 500 run a 12v cooler / fridge?

Yes — the Power 500 runs a 12v cooler / fridge comfortably. Its 1000W continuous output easily covers the 45W draw, with 1000W of surge on tap for startup.

Q: How long will the DJI Power 500 run a 12v cooler / fridge?

The DJI Power 500 has 512 Wh (about 392 Wh usable at the outlet, estimated). Running a 12v cooler / fridge that draws 45W, it lasts about 9 hours on a single full charge.

Estimated runtime

on a single full charge

Est. usable (AC): 392 Wh

Appliance draw: 45 W

Continuous output: 1000 W

How we calculated this

We start from the DJI Power 500's 392 Wh of estimated usable energy at the outlet — its 512 Wh rating, derated for a safe depth of discharge and ~15% inverter loss — then divide by the 12v cooler / fridge's 45W draw:

392 Wh ÷ 45 W ≈ 8.7 hours

Heads up: a 12v cooler / fridge is a motor/compressor load that spikes 2–3× on startup. The DJI Power 500's 1000W continuous / 1000W 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.
