How long will the EcoFlow DELTA Pro 3 run a microwave?

About 2.5 hours from a full charge. A microwave averages about 1,500 W, and the 4,096 Wh battery gives about 3,482 Wh after inverter losses. That is 43% of the battery an hour.

Can I run other things at the same time?

Yes, up to about 2,500 W more of the 4,000 W output. Each thing you add shares the same battery, so the 2.5 hours for a microwave gets shorter.

How many days of normal use is that?

About 9 days, if you use a microwave about 15 minutes a day and nothing else is plugged in.
