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 RTA's 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. The wicking holes have been perfectly positioned to allow cotton wicks to dip into the tank. 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.

Important information about Rebuildable Tank Atomisers:

Rebuildable atomisers are recommended only for experienced vapers. You should have the knowledge and access to the equipment that is required to set up this atomiser properly.

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

Before fitting a coil onto your rebuildable atomiser ensure it is in a safe condition and registering the correct Ohmage, this testing and checking can be achieved by using a dedicated Ohmmeter. Coils should not be tested on vape devices.
