Wotofo COG MTL RTA - 2ml 22mm Single Coil Tank

The Wotofo COG MTL RTA is a 22mm single coil rebuildable tank atomiser made for mouth-to-lung vaping, created in collaboration with SuckMyMod. It suits builders who like nic salt e-liquids and want precise control over the airflow reaching the coil.

Key features

• Single coil build deck, 22mm diameter
• 2ml tank capacity
• Gear mechanism with five internal air inlets
• Airflow holes of 1.6mm, 1.4mm, 1.2mm, 1.0mm and 0.8mm
• Spring-loaded clamps for coil installation
• 510 Delrin drip tip designed to condense vapour for mouth-to-lung draws
• PCTG tank tube

The airflow system is the main talking point. Rather than a single inlet, the COG has five internal inlets set within the base. Twisting the base ring turns the internal gear and lines up one inlet so air is delivered directly beneath the coil. You pick the airflow hole size that suits you and fine-tune from there. The build deck uses spring-loaded clamps, which makes fitting a coil quicker, and the deck spacing is intended for MTL coil builds. The Delrin drip tip is a 510 fitting, and the tank tube is made from PCTG, which Wotofo chose for toughness and clarity.

Choosing your colour

The COG MTL RTA is available in six colours: Black, Blue, Gold, Gun Metal, Rainbow and Stainless Steel. The colour is the only difference between the options on this page.

How to use

1. Fit your coil to the deck and secure it with the clamps, then trim the leads.
2. Thread the wick through the coil and trim it so it sits neatly in the deck without being packed in tightly.
3. Wet the wick with e-liquid and let it soak before you fill the tank.
4. Fill the tank, leave it a few minutes to saturate, then set the airflow by twisting the base ring.

Always check the resistance of a new build on a suitable device before firing it, and never fire a dry coil.
