The Sigelei 100w Plus is an upgraded version of the original Sigelei 100w box mod. The Plus version has a new look with engraved edges and wave designs on the case, it’s available in either black or gold. Other upgrades over the original version include an upgraded spring-loaded contact pin and a fully magnetic back plate, no more messing around with screws. Like the first version the Sigelei plus is powered by the popular SX330 chip-set capable of outputting from between 10 to 100 watts, adjustable in 0.1 watt increments. This chip also allows you to use atomizers with builds as low as 0.15 ohms and as high as 3.0 ohms.
