The COG MTL RTA is a mouth-to-lung RTA designed especially for builders who prefer high nicotine vaping. It’s the new collaboration between Wotofo and Suck My Mod, featuring single coil setup on a 22mm build deck and 3ml tank reservoir.


The COG is paired with a drip tip that is designed to condense the vapor for mouth to lung draws. Made of delrin and sized in 510, it keeps heat down to a minimum while offering tremendous flavor.


The COG MTL RTA has an innovative gear mechanism for very precise air tuning. Simply twist the base to fine tune your perfect draw. As the base ring moves, the mechanism transmits the rotary motion to the internal gear which works like a revolver cylinder, aligning 1 of the 5 internal inlets with the only passage that directs an accurate amount of air right underneath the coil.

Though the air hole on the base ring can be adjusted, traditional MTL RTAs take air from the base interior with a one-size inlet to the coil, which actually is still not truly regulated airflow control. The COG, utilizing the gear mechanism, has 5 different internal air inlets that accurately control the amount of air and path approaching to the coil, giving MTL users customized draws for real.


The COG features spring-loaded clamps for easier and faster coil installation. Spaced in an appropriate size for MTL coil builds, it can deliver dense and flavorful clouds efficiently.


The tank tube is made of PCTG material, which is food safe as granted by FDA. It offers increased toughness while still providing extremely high clarity. A little tip here for you is that we don’t recommend washing the tube with hot water.
