SMOK TFV9 Mini Tank, featuring a 3mL tank capacity, stainless steel tank construction, and is compatible with the TFV9 Mesh Coil Series. Outfitted with a sliding top fill system, the TFV9 Mini Tank can hold up to 3mL of e-juice refilled via single fill port. Formed from superior 304 stainless steel, the tank construction is quite durable and impact resistant while maintaining a visually striking profile. Accommodating coils from the TFV9 Coil Series, the TFV9 utilizes less power to create more vapor and flavor from your favorite e-juice, thanks to the mesh heating element within. At the base is a 510 threaded connection and dual slotted airflow control system to carefully meter the amount of airflow going to the coil.
