How long will the Goal Zero Yeti 1500 run a portable fan?

Will the Goal Zero Yeti 1500 run a portable fan?

Yes — the Yeti 1500 runs a portable fan comfortably

Its 2000W continuous output easily covers the 40W draw.

Estimated runtime
about 1.2 days (~29 hours)
on a single full charge
Est. usable (AC): 1,152 Wh
Appliance draw: 40 W
Continuous output: 2000 W

How we calculated this

We start from the Goal Zero Yeti 1500's 1,152 Wh of estimated usable energy at the outlet — its 1,505 Wh rating, derated for a safe depth of discharge and ~15% inverter loss — then divide by the portable fan's 40W draw:

1,152 Wh ÷ 40 W ≈ 28.8 hours

Real-world runtime varies with temperature, cable losses, and how hard the appliance actually cycles. Treat this as a solid estimate, not a guarantee.
