The tank is the hub of a vape. It is here that everything comes together. Not only does it house the e-liquid and coil, the tank is responsible for feeding the juice to the coil at the correct speed and with the right amount of airflow to produce the perfect vape for the user. There are two main styles of tanks, mouth to lung (this provides a stronger more intense hit of nicotine similar to the way a cigarette works) and direct lung (a smoother and lighter nicotine hit).
