How long will the BLUETTI Apex 300 run a laptop?

About 3 days from a full charge. A laptop averages about 39 W (65 W running, on about 60% of the time), and the 2,765 Wh battery gives about 2,350 Wh after inverter losses. That is 1.7% of the battery an hour.

Can I run other things at the same time?

Yes, up to about 3,775 W more of the 3,840 W output. Each thing you add shares the same battery, so the 3 days for a laptop gets shorter.

How many days of normal use is that?

About 10 days, if you use a laptop about 6 hours a day and nothing else is plugged in.
