I bought the Istick 50w by eleaf a couple of weeks ago from Vape NW online. I had no problems with it until about a couple of days ago. When I would go to fire it, it wouldn't fire and the display would read no/low battery when in fact it was charged at least to 50%. I was only running it between 35/40w, so I know I wasn't draining the battery. Well earlier this morning it was acting fine, but later it began to really get on my nerves because it was not firing at all. Before it would say low/no battery, but then after trying to fire again it would work fine. This time, though, it wouldn't even fire. Then all of a sudden it began firing again, but then I started getting this weird taste, almost like a dry hit, but different. I checked my tank (aspire atlantis) and it was fine (plenty of juice and screwed on correctly.) I decided to take one last hit off it to see if it was just a bad hit, but then I heard a pop and saw smoke pouring out of the charging port. I don't know what that exactly means, but I know that isn't good. The thing won't even turn on now, but even if it did, I wouldn't want to use it. Has anyone else had a problem in general with their Istick 50W? I just sent Vape NW an email about this. I haven't even had the product for a month, I purchased it on March 31st and received it about a week later.
