Ran my Darwin down to cut-off for the first time yesterday. Not intentionally, of course. Even knowing the indicator wasn't a linear representation of batt life, I didn't realize just
how fast that battery level indicator goes down after it passes the halfway point on the bar

I was just vaping along on a 3 ohm boge carto and the screen started flickering, I look down and the gauge is completely empty. Still, I got nearly two full days on it

(for the record, it was a little less volume of juice than normal, I had to up my nic a bit after the absolute hell that was this past week

)
One of the USB ports on my laptop is fried and the other two were in use, so I couldn't plug it in there (
thought I had plenty of vape time left anyway), and my wall adapter to USB chargers were all packed in my checked bag which didn't make my connecting flight on the way home . . . heck, I almost didn't make my connecting flight, either. My bag arrived home a little more than 24 hours after I did, but at least it
did arrive. I've learned my lesson, though, I will keep my chargers in my carry-on next time I travel.
