What happens in this China mess we are in .....is confusion. I think i understand because i bought 2 Joyetech kits in june. What makes it confusing is they put "c" on the battery and that has no meaning for the battery. The "c" has meaning when refering to the "changeable" system. My box is labeled "the ego-c , changeable system." The cone is labeled "c".
Anyhow, back to the problem.
Got my "c" up and running.
When you took the tank out, and got smoke, it sounds like what you did was a "dry-burn", which would make smoke, the gunk is being burnt off the coil. The "c" can have wicking issues, not much wick there. And its not easy to clean, the reason many of us have moved on to other things. The outside cone can get nice and warm, may be used for a hand warmer in the winter. Anyway, i wait to you get back and give an update.
