Hello, someone put a kangertech toptank e cigar on my backpack a few weeks ago, and until now i decided to try it because why not. I swapped the coil that it already had (wich had no cotton at all for some reason) and got a 60% VG oil for the new coil, wich was a .5 clapton coil i got on the mail today. I noticed at first popping sounds and burned taste after 2-3 seconds of pressing the battery button (its the standard battery that comes with the toptank nano), but after trying solutions for dry burns, i actually noticed that the base of the atomizer gets really hot. So i can vape for around one or two seconds before it actually starts to overheat the oil and cause the burning taste and coughing. Has anyone else experienced this? I think it might be the coil, even if the website says its compatible, its a bit bigger than the one it had. Because the old one has no cotton im afraid of trying to use it to check if it works.
