How long will the DJI Power 500 run a portable ac (small)?

Q: Will the DJI Power 500 run a portable ac (small)?

Probably — but the startup surge runs close to the limit. A portable ac (small) can spike to roughly 2700W for a moment on startup, near the Power 500's 1000W surge rating. It usually works, but pairing it with other loads may trip the unit.

Q: How long will the DJI Power 500 run a portable ac (small)?

The DJI Power 500 has 512 Wh (about 392 Wh usable at the outlet, estimated). Running a portable ac (small) that draws 900W, it lasts under an hour on a single full charge.

Est. usable (AC): 392 Wh

Appliance draw: 900 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 portable ac (small)'s 900W draw:

392 Wh ÷ 900 W ≈ 0.4 hours

Heads up: a portable ac (small) is a motor/compressor load that spikes 2–3× on startup. The DJI Power 500's 1000W continuous / 1000W surge output should be checked against that startup 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.
