How long will the BLUETTI Apex 300 run an electric kettle?

About 1.5 hours from a full charge. An electric kettle averages about 1,500 W, and the 2,765 Wh battery gives about 2,350 Wh after inverter losses. That is 64% of the battery an hour.

Can I run other things at the same time?

Yes, up to about 2,340 W more of the 3,840 W output. Each thing you add shares the same battery, so the 1.5 hours for an electric kettle gets shorter.

How many days of normal use is that?

About 7 days, if you use an electric kettle about 10 minutes a day and nothing else is plugged in.
