Combining hardy designs with useful functions, the MDura Pro Box Mod is waterproof, dustproof and shockproof. It can withstand various out-door environments, tough enough to be dropped on hard surfaces without causing a damage. With accommodation of dual 18650 batteries, the MDura Pro outputs a maximum power of 230W. There are a range of other great features here, large touch screen with slide to unlock gesture, six theme color options, temperature control mode, instant firing time and more. Engineered to meet the IP67 specification, meaning it’s a 6 against dust (complete protection), and a7 against water (30 minutes in water that’s at least 0.5 meters deep, up to 1 meter deep).
