Mini style and smart performance. Two main factors make the R-Steam Mini a must have box mod. Packing a punch to a max 80W, temperature control function with a variety of heating wires, and the option to upgrade the chip's firmware, not only is this mod versatile, but it is also compact. At 28*38*22.3mm, this is the perfect on-the-go box mod that features all of the necessary functions of the larger mods. Although small, the R-Steam boasts a sizable 0.91 inch OLED screen to display the many power settings integrated into the chipset. Well built from high quality zinc alloy for a lightweight and sturdy mod, the R-Steam Mini features a slim and compact body that is comfortable to hold in the hand.
