Voopoo’s newest atomizer is the first patented MAAT tank in the industry, adopting a middle adjustable airflow design which comes in from a hidden airflow system. The airflow does come in from the bottom, and is fully adjustable as well. In addition, this type of design allows for a smooth and flavorful vape experience. Another great design the VooPoo Maat Sub Ohm Tank features is a plug and play coil system. This allows you to change coils without any mess, which is always a good thing!
