The Dotmod dotAIO V4 Replacement Tank is a next-generation empty tank system developed for the dotAIO platform, featuring a 4 ml e-liquid capacity, a swappable dotCoil system, improved airflow control, and a new internal structure designed to help reduce leakage.
The dotAIO V4 Replacement Tank offers a next-generation design that improves upon airflow and internal chimney structure while maintaining the ease of use of previous dotAIO tank systems. Thanks to adjustable airflow and various dotCoil resistance options, a wide range of vaping styles can be achieved, from tight MTL draws to more open RDL and DL usage.
The dotAIO V4 Tank uses a swappable coil system. When the coil reaches the end of its lifespan, you can simply replace the dotCoil instead of replacing the entire tank.
Draw: More open
Vapor: Denser
Character: High power and direct-to-lung oriented
This is the standout dotCoil option for users seeking dense vapor and a more open airflow.
Draw: Medium-open
Vapor: Dense and balanced
Character: Flavor and vapor balance
A balanced option for users wanting a more controlled DL or open RDL experience.
Draw: More controlled
Vapor: Medium density
Character: Lower power and controlled usage
One of the suitable options for users desiring airy MTL or controlled RDL usage.
One of the key features of the V4 Tank is that the coil is not permanently integrated into the tank. Thanks to this structure, when the coil reaches the end of its lifespan, only the dotCoil can be changed instead of discarding the entire tank.
The updated airflow system of the dotAIO V4 Tank allows the user to adjust the draw tightness according to their own preference. Narrowing the air channel provides a more controlled and tighter draw, while opening the airflow creates a more comfortable and high-vapor-focused experience.
The updated internal structure of the V4 Tank is designed to manage e-liquid and airflow in a more controlled manner. The new anti-leak structure helps to reduce leaks that may occur during daily use, while the vortex internal chimney system ensures that air and vapor flow are directed to the mouthpiece in a more controlled way.

Remove the tank from the device and place the appropriate dotCoil into the tank base.
Ensure the coil is seated correctly without any gaps.
Fill the tank with suitable e-liquid and close the filling cap completely.
Before using a new coil, wait about 10 minutes for the cotton to absorb the e-liquid.
