Yeah I guess I'm a fairly heavy vaper too now with using the Provari and Darwin especially and I can't get through a day with one charge on a Darwin and I find an 18650 lasts longer which is why I was asking if a bigger battery is possible. But if you're at a computer or near an outlet with I think somebody said a 2A wall adapter to USB cord you can use it like a passthrough sorta and get much better life that way. You could have a cord plugged in your computer and one near your chair and chain vape away unless it gets in somebody's way. Also someone said you can leave it plugged into your USB indefinitely and it will stop charging when full, I do it while it's off and I'm using something else and then I'll check if it's full and unplug it just in case.
Very good. Sounds like there is nothing wrong with the device, then.
Never thought in a million years I'd see that, but it really can be done if you work at it
