What are the main improvements on the dotAIO V4 Tank compared to older versions?

The V4 Tank introduces a highly reliable anti-leak construction and an advanced internal vortex chimney designed to deliver a smoother, flavor-dense inhale. It also features an updated, highly adjustable airflow control base.

Will this tank work with my original dotAIO or dotAIO V2?

Yes! The V4 Tank features strict backward compatibility, allowing it to integrate perfectly with the dotApollo, dotAIO X, dotAIO V2, and legacy standard dotAIO models.

Does the replacement tank come with a pre-installed coil?

No, the package includes one replacement reservoir and the matching adjustable airflow control base. Coils are sold separately.

Which coils should I use with the dotAIO V4 Tank?

This tank is designed to host the high-performance dotCoils series (available in 0.15Ω, 0.3Ω, and 0.6Ω), allowing you to swap resistances based on your preferred wattage and e-liquid type.

How do I prime a new setup using this tank?

Push your replacement coil securely into the bottom of the V4 tank, screw on the airflow base, and fill it through the side port. Crucial Step: Always let a brand new coil sit inside a filled tank for 5 to 10 minutes before firing to ensure the cotton is completely saturated and prevent dry burns.
