It is capable of holding a maximum e-liquid capacity of 5ml. The Zeus Sub-ohm tank uses a leak-proof design and top airflow system to provide an enjoyable vaping experience.

Geekvape Z Sub-ohm Tank

 There two new MeshZ replacement coils included in the kit, a 0.2ohm Z2 mesh coil rated for 70 - 80W and a 0.4ohm Z1 mesh coil rated for 50 - 60W. Throughout my time testing, both coils wick quickly and I never experienced dry hits when used as chain vaping. I can get superb flavours and pleasant cloud from these two coils. I’m impressed with the performance of the Z2 coil as its slight increase in flavour.
