How long will the DJI Power 2000 run a box fan?

About 20 hours from a full charge. A box fan averages about 85 W, and the 2,048 Wh battery gives about 1,741 Wh after inverter losses. That is 4.9% of the battery an hour.

Can I run other things at the same time?

Yes, up to about 2,915 W more of the 3,000 W output. Each thing you add shares the same battery, so the 20 hours for a box fan gets shorter.

How many days of normal use is that?

About 2 days, if you use a box fan about 8 hours a day and nothing else is plugged in.
