poor at best. To be fair, I havent charged it fully yet...gone through 3 half-charges in two days so far..so I would guess about a days use at moderate wattages (10-15 range). Probably 1hour consecutive vape time...but that is still a guess.
on aqua @ 1.8ohms, firing about 13-15 watts.
Luckily, hobbyking do a 1s turnigy battery that fits...which I will get as a spare/future/backup item. Its only a few dollars.
I do think though the low voltage cutoff is too high on this cloned chip (shows evolv at startup), leading to poor runtime. But it is so dinky and small it is a nice device for in-car use, or for popping out a bit for a few hours..that type of thing. If it was 18650, I would do the magnet upgrade to get to the cell quicker, and just swop them out. But as it stands now, it does fill a small gap and I'm totally charmed with it
my *only* gripe is I am too stupid to figure out how to lock the wattage settings. Tried both up+down for two seconds when locked and when unlocked and its either not there, or I am thick.
