The Protank 4 is a fully updated tank with a clean design and long list of features. The Protank 4 has a locking top fill ring that twists and lifts for ultra-fast and leakproof filling. The 510-compatible driptip features fully adjustable afc slots. Large airflow control slots sit at the base of the tank as well; also fully adjustable, they help transform the tank from a flavor-chasing subohm beast to a tightly-controlled, analog-like atomizer with a satisfying MTL draw. With a juice capacity of 5mL, the Protank 4 will keep puffing all day long, and its gold plated centerpin ensures a solid connection with your mod.
