The Geek Vape Z Max Sub-Ohm Tank features a 4mL bubble glass e-Juice capacity and a 26mm base diameter with a quarter turn top filling system with a dual slotted airflow to provide optimal airflow and significantly enhanced flavor production. The two large fill ports will accommodate any nozzle size and reduce the positive pressure from the tank, eliminating the possibility of leaks. The Zeus Sub-Ohm Tank delivers a smooth draw and ample airflow. The Z Max Kit includes the 0.2ohm and 0.13ohm M series Mesh coils.
