IJOY just release a smaller version of its Tornado RTA tank-- the Tornado Nano, which features a detachable structure with 4ml tank capacity. Like its big brother, this Tornado Nano is also equipped with a big build deck, two post velocity style, 18.6mm in diameter, making various coil builds way easier. Except for the RBA option, this new tank comes with an innovative chip coil which is 0.3ohm, rated for use at 40-80 watts, offering you remarkable sub-ohm vaping experience. Another interesting feature is that this Tornado Nano uses a color change glass, which really arouse my curiosity. Any thoughts, you guys?
