How long will the BLUETTI Apex 300 run a 55-inch LED TV?

About 26 hours from a full charge. A 55-inch LED TV averages about 90 W, and the 2,765 Wh battery gives about 2,350 Wh after inverter losses. That is 3.8% of the battery an hour.

Can I run other things at the same time?

Yes, up to about 3,750 W more of the 3,840 W output. Each thing you add shares the same battery, so the 26 hours for a 55-inch LED TV gets shorter.

How many days of normal use is that?

About 6 days, if you use a 55-inch LED TV about 4 hours a day and nothing else is plugged in.
