Home / Runtime by device / How long will a power station run a box fan? Hours on every unit Runtime by device · Fan
How long will a power station run a box fan? 55 of 56 units can run it. The smallest is the EcoFlow RIVER 3 Plus (286 Wh, about 2.7 h). 42 hold 8 hours of a box fan with the calculator's 20% headroom.
A 20-inch box fan draws 65 W on low and 90 W on high (Lasko's figures); this page uses the high setting. Its motor draws about 1 A at 120 V, about 120 volt-amps, so give the inverter some room beyond the 90 W, which every unit here has.

What changes these hours On low, runtime is about a third longer than shown. A DC fan run from the 12 V socket avoids the inverter's losses altogether.
The 0.85 allowance covers the inverter's conversion losses on average; at very small loads its own idle draw takes a larger share, and at
very large ones the battery delivers a little less. Cold batteries hold less, and an older battery holds less than its rating.
To plan a whole day with other devices and 20% headroom, use the calculator with 8 hours of a box fan already added .
Also: a camping weekend , an outage , and every device .
Questions buyers ask How many watts does a box fan use? Box fan, 20 inch: 90 W. Your own model's label or manual has its figure; put it into the calculator's custom row to size for exactly yours.
What size power station do I need for 8 hours of a box fan? 1,017 Wh of rated capacity by the calculator's arithmetic (device watts × hours ÷ 0.85, plus 20% headroom), with at least 90 W of surge. 42 tracked units clear it.
