How many nights will the BLUETTI Apex 300 run an electric blanket?

About 3 nights of 8 hours (31 hours in total). An electric blanket averages about 75 W (150 W running, on about 50% of the time), and the 2,765 Wh battery gives about 2,350 Wh after inverter losses.

Can I run other things at the same time?

Yes, up to about 3,690 W more of the 3,840 W output. Each thing you add shares the same battery, so the 31 hours for an electric blanket gets shorter.
