How long will the EcoFlow DELTA Pro 3 run a drip coffee maker?

About 3.5 hours from a full charge. A drip coffee maker averages about 1,000 W, and the 4,096 Wh battery gives about 3,482 Wh after inverter losses. That is 29% of the battery an hour.

Can I run other things at the same time?

Yes, up to about 3,000 W more of the 4,000 W output. Each thing you add shares the same battery, so the 3.5 hours for a drip coffee maker gets shorter.

How many days of normal use is that?

About 13 days, if you use a drip coffee maker about 15 minutes a day and nothing else is plugged in.
