The Geek Vape Zeus Sub-Ohm Tank uses mesh coil atomizers, providing a pair of kanthal mesh coils clocking in at 0.4ohm and 0.2ohm respectively. The Geek Vape Zeus Sub-Ohm Tank is leakproof, just like it's predecessors, relying on a top to bottom airflow control system to provide the proper airflow to rush through the internal coil structure.
