The Wotofo COG MTL RTA is an innovative RTA (Rebuildable Tank Atomiser) that has been designed to produce a discreet amount of vapour supporting mouth to lung vaping. Featuring a specially designed airflow system it features a beginner-friendly build deck that will support single rebuildable coils. Capable of holding up to 2ml of e-liquid, this RTA is recommended for advanced vapers only.

This RTA gets its name from its unique airflow system. Traditional RTAs feature adjustable airflow but they don’t actually alter the size of the air inlet inside the atomiser itself. The COG features a unique gear airflow system, whereby through twisting the base you can switch between one of five airflow inlet sizes. This, in turn, reduces or increases airflow to match your vaping style. The result is a truly individual mouth to lung vaping experience.

A spring-loaded clamp build deck makes coil fitting a quicker and simpler process overall. When fitting your coil you can place it, secure it and then trim it, meaning there’s very little preparation involved. To accentuate the mouth to lung vaping style this rebuildable adopts, it is recommended that you use a smaller rebuildable coil that features a higher resistance. Capable of holding up to 2ml of e-liquid, top filling enables a quicker and cleaner refill.

Before building coils or using an RTA you should have a thorough knowledge of battery safety, Ohm’s Law and vaping in general.
