How long will the EcoFlow DELTA 3 run a microwave?

About 35 minutes from a full charge. A microwave averages about 1,500 W, and the 1,024 Wh battery gives about 870 Wh after inverter losses. It would empty the battery in about 35 minutes.

Can I run other things at the same time?

Yes, up to about 300 W more of the 1,800 W output. Each thing you add shares the same battery, so the 35 minutes for a microwave gets shorter.

How many days of normal use is that?

About 2 days, if you use a microwave about 15 minutes a day and nothing else is plugged in.
