JUST EXACTLY WHAT HAPPENED TO ME 30 MINUTES A GO.
I charge the cloupor on USB port. It was charged for about 2 hrs.
I passthrough it about one or two puff every 15 minutes of longer.
The last passthrough went a bit weak but I do not notice any other strange , so I just put it back on my desk ( still USB charging )
3-5 secs later smoke come out from the USB port of the Cloupor strong lingering burnt plastic smell easily noticed.
Then I opened the cover and it shows a light of fire right next to the cloupor seal sticker.
The smoke getting more intense, then I drop it down to a box and pour water on it.
Fire light stopped, but I can still hear some crackling voice.
Then I take the battery out ( honestly I was kinda scared it will somehow blew, because of the trickeling sound )
(By the way, that is my 1st time passthrough on VV mode - 3.6v, usually on VW mode -10w, I wonder if it somehow related )
Then , my less than 2 months old Cloupor now have a hole.
