My Hcigar Vt200 is doing the same, its always warm when plugged in even if it is fully charged. If I dont use it for 2-15min, the screen goes off and needs to be plugged in for it to wake up. My other dna200 from vapecige has been working perfectly. Photo of the temperature after it has been plugged in for 24 hours or so, not used, board is at 97F in full idle, my other mod is 85F even when in frequent use. /topic/67027-topic/?do=findComment&comment=903151
