I have just bought a Kanger subtank mini for my Istick 50w, but the only coil that will work on it is the RBA coil 
Whenever I install one the two OCC coils, the display says "power low" even if my Istick if fully charged. I´ve read on vaping 360 that this tank should be a great fit with my Istick, so why doesn´t it work???
