The Wismec Reuleaux RX GEN3 DUAL 230W Starter Kit is a powerful, yet more compact version of the original RX GEN3, and is powered by (2) high amp 18650 batteries (sold separately). The smaller, sleek chassis maintains all of the performance and functionality you expect from a Reuleaux. The slide and lock battery access door at the base of the device makes changing batteries simple and fast, and a giant 1.3 Inch OLED screen makes reading your settings easy. The device fires up to 230W or can function in temperature control modes for Ni200 Nickel, Titanium, and Stainless Steel coils. The chipset is upgradeable to keep current with improvements in technology. Included in the kit is the GNOME King Sub-Ohm Tank offering 5.8mL e-liquid capacity, an easy sliding top-fill method, and adjustable dual bottom airflow… all designed to give you amazing vapor and flavor every time!
