Thanks for responding so quickly, I don't have the packaging to the kbox so I'm not sure, the istick is tc 40w.
I do have another question though, is it normal to hear a crackling sound when I draw in?
I just bought an e-leaf melo 2 tank and am using the coil that came with it! I am not using temp control. The coil is a 0.3 ohm coil and I am wondering how many watts I should be using! I am switching between a kangertech Knox mini and an e-leaf istick. Any help will be appreciated!
