In order to be lighter, we use the aluminum-alloy body on HANNNYA MINI. The oxidized black is very handy. Although MINI is smaller in size and has only one 18650 battery drive, profits from our adjustment for power conversion efficiency, MINI also has strong explosive power and amazing ignition speed. HANNNYA MINI has a minimum support of 1.0Ω heating wire and 510 stainless steel interface compatible with most atomizers of market. Whether you are a competitor or an amateur player, MINI will definitely give you a perfect experience.
