You're gonna love the looks of it.
Personally I haven't tried one, but very tempted, also because of the size and the charging capabilities.
Update: Decided to check one out...and buy it (yes, I have to buy my own stuff).
Checking out the manual, says nothing about charging, USB cable, etc.
Plugged it in and vaped, no errors, and it is charging. So I see no issues there.
One point with that though is that it will likely take much longer to charge than a standard charger.
Me very happy with it, with the Triton tank and the VA Premium eLiquid:
