A result from many repeated improvements, the TFV8 X-Baby improves on what previous versions lacked. Based off of the initial design of the TFV4, the TFV8 X-Baby takes all of the features and embraces them tenfold. The upgraded top airflow, coil system, tank filling, and tank capacity proves to be just as good as the full size TFV8. Featuring large dual cyclops top adjustable airflow, this tank allows you to finely tune the air until you find that sweet spot while being located at the top of the unit to prevent leakage coming from the air holes. The diameter in center chimney has also been enlarged to allow more air to travel through the tank for the least amount of air restriction. While the swivel top fill feature remains generally the same, the fill port size has increased for easier filling and less of a juicy mess. Smok’s famous TF sub ohm tank series is back at it again with top level performance and innovative designs to make it one of the most sought after sub ohm tanks in the market.
