Will the Goal Zero Yeti 1500X run a portable ac (small)?

Yes — the Yeti 1500X runs a portable ac (small) comfortably

Its 2000W continuous output easily covers the 900W draw, with 3500W of surge on tap for startup.

Estimated runtime

about 1.2 hours

on a single full charge

Est. usable (AC): 1,096 Wh

Appliance draw: 900 W

Continuous output: 2000 W

How we calculated this

We start from the Goal Zero Yeti 1500X's 1,096 Wh of estimated usable energy at the outlet — its 1,516 Wh rating, derated for a safe depth of discharge and ~15% inverter loss — then divide by the portable ac (small)'s 900W draw:

1,096 Wh ÷ 900 W ≈ 1.2 hours

Heads up: a portable ac (small) is a motor/compressor load that spikes 2–3× on startup. The Goal Zero Yeti 1500X's 2000W continuous / 3500W 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.
