The Kanger Aerotank V2 features the same great performance and build quality of the original Kanger Aerotank, but with a newly redesigned airflow valve for ultimate cloud control. By simply turning the dial on the base of the tank allows you to effortlessly increase or decrease the airflow to your personal preference. The Aerotank V2 comes with a standard Pyrex glass tank, as well as a unique stainless steel tank for increased durability. In addition, the V2 features newly redesigned atomizer heads to prevent leakage. This tank utilizes BDC (bottom dual-coil) atomizers, and features 2.5ml e-juice capacity, as well as universal 510 threading.
