Evening guys.. just a quick one.. are the coils that come with the Kangertech tank TC compatible. .especially with regards to the 15-60 watt OCC ones that come with the kit.. I see on the eleaf 40w in TC mode has NI next to the temp.. does this mean nickel coils.. I tried it earlier and the vape was really good ... but then being a newbie thought I best check before I blow my tank...
