The Tornado Sub Ohm tank brings a breath of fresh air into the world of vaporizers. The already installed 0.3 ohm coil is made of SS316L stainless steel and can withstand a battery power of a remarkable 150 watts. Despite its compact design, the evaporator has a tank volume of proud 4.2ml. The small iJoy vaporizer promises a first-class taste that is unparalleled in the class of minivans. The bottom airflow also ensures an extremely light draft and plenty of steam. Even self-winders get their money's worth thanks to the enclosed RTA. The RTA coil is generously dimensioned and has enough space for exotic windings.
