Will the EcoFlow River 2 Pro run a portable fan?
Yes — the River 2 Pro runs a portable fan comfortably
Its 800W continuous output easily covers the 40W draw.
Estimated runtime
about 15 hours
on a single full charge
Est. usable (AC): 587 Wh
Appliance draw: 40 W
Continuous output: 800 W
How we calculated this
We start from the EcoFlow River 2 Pro's 587 Wh of estimated usable energy at the outlet — its 768 Wh rating, derated for a safe depth of discharge and ~15% inverter loss — then divide by the portable fan's 40W draw:
587 Wh ÷ 40 W ≈ 14.7 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.
