When TC works I love it but.... Ok so I woke up a little while ago with device off all night. I go to use my Joytech Cuboid with Kanger Nano Ni200 coils, the original nano not the newer one with redisgned coils. I keep getting Temp Protection. The settings are 450f and 40w of power. So what is "Temp Protection" and why does the mod start at 200f? Is it possible to use it at 200f? Oh, I did try changing the watts from 150 down to 20w. I just dont get the 200-600f range when it seems to only work between 5and6 hundred so what am I not getting about TC? Is it the Kanger coils?
