Well got sometime today, to do a quick full breakdown of how battery lasted for me.
My use is not far off, I died into the 6th. But I let the unit auto off, instead of manually turning off, so that is a factor. For those with shorter times reported, it might be due to first use. Even though I did charge the unit to full before first use, the battery died down quicker the first time compared to subsequent charges. But maybe just an anomaly on my end....
I really want to see how fast this unit can extract.
It extracts fast; it really comes on immediately and vapor is thick. I will have to warn friends not to just 'rip it'; nice slow draw, half breath is perfect. It does seem to cook very slightly when left in the hot chamber, so I think manual turn off will save both battery and bowl longevity.
