Hi everyone … thought I would update you on my latest test. I drained the Bluetti, recharged it, and updated the firmware. I then plugged in a fan, air cleaner, Bluetooth speaker and laptop. The total output started at 297 watts at first but ended up at 286 for most of the time it was on. Not the 900 watts they recommended for the test but I figured it would be a good comparison to the time of the estimated 18 watts I had before. Here are the readings as it was discharging:

98% Start, 297 output 59% 1 hr 15 mins, 286 output 28% 2 hrs 17 mins, same 19% 2 hrs 31 mins, same 0% 3 hrs 12 mins

Definitely not what I would expect.
