How these runtimes are calculated: runtime = usable capacity ÷ average draw of 83 W (the running draw, assumed on the whole time). Usable capacity is an independent test's measured figure, or 80% of rated capacity where none exists, marked "(est.)". A model must also carry the running watts continuously and the startup peak within its surge rating. The same formula applies to every model; see the methodology.

What size do you need?
What size power station do I need for a box fan (20 inch)?
Look for at least 83 W of continuous AC output and 83 W of surge. For capacity, a box fan (20 inch) averages about 83 W, so 8 hours needs roughly 850 Wh of rated capacity and 24 hours roughly 2,500 Wh, assuming 80% of rated capacity reaches the outlets.
How long will a 1,000 Wh power station run a box fan (20 inch)?
About 9.6 h for a generic 1,000 Wh unit, if its inverter can handle the 83 W startup surge: roughly 800 Wh (80% of rated) reaches the outlets, divided by an average draw of 83 W. Measured models of this size vary; see the table above.
Which power station can run a box fan (20 inch) for a full day?
Of the 15 models we track, the smallest that runs a box fan (20 inch) for 24 hours on one charge is the Anker SOLIX F3800. Larger models run it longer; see the table above.
