Why does the BLUETTI Elite 30 V2 run a window AC 5,000 BTU for so little time?

Because it draws a lot of power. A window AC 5,000 BTU averages about 225 W (450 W running, on about 50% of the time), and the 288 Wh battery gives about 245 Wh after inverter losses. That is 92% of the battery an hour.

What would run a window AC 5,000 BTU longer?

A bigger battery: the 998 Wh Goal Zero Yeti 1000 (6th Gen) about 4 hours and the 1,024 Wh EcoFlow DELTA 3 Plus about 4 hours.

Short answerYes, briefly

Yes, but only for about 1 hour. A window AC 5,000 BTU averages about 225 W, and the BLUETTI Elite 30 V2 holds 288 Wh (about 245 Wh usable after inverter losses), so the battery runs down fast. Fine for a short job, not for a whole day.
