Well this sucks, I have an iStick 30w and toptank mini, I ran out of pre made coils so I thought i would try the RBA of the toptank. At first it read out as “protection” upon trying to fire it (I think the ohms were too low on the pre made coils included with the RBA at .1), then it said low battery (it was almost fully charged) so i plugged it in and tried to fire it once more and the thing started smoking (no protection message this time, just a little puff of smoke within the LED window). I only fired the button for a split second and it still seems to be functioning. Not sure what I should do lol or just ditch out on it? It appears to be working yet but stinks like an electrical fire now. I’m kinda reluctant to use it (I still have an old coil but it was starting to taste funky). Any advice or idea what might’ve happened?
