Uwell Crown IV Tank Color:Purple The battery life will beUwell Crown IV Tank The Crown IV is the TPD compliant fourth generation of the much loved original Crown Tank from Uwell. It still holds the same excellent build quality and flavour you'd expect from Uwell. The Crown IV has adjustable airflow which allows the user to choose how tight or loose the draw is. For a smooth, airy vape with lots of vapour, the air hole should be open. The air hole should be nearly closed for a tighter draw with less vapour.
