How long will the EcoFlow DELTA 3 Plus run a laptop?

About 22 hours from a full charge. A laptop averages about 39 W (65 W running, on about 60% of the time), and the 1,024 Wh battery gives about 870 Wh after inverter losses. That is 4.5% of the battery an hour.

Can I run other things at the same time?

Yes, up to about 1,735 W more of the 1,800 W output. Each thing you add shares the same battery, so the 22 hours for a laptop gets shorter.

How many days of normal use is that?

About 3 days, if you use a laptop about 6 hours a day and nothing else is plugged in.
