The Zenith Tank by Innokin (in collaboration with Phil Busardo and Dimitris Agrafiotis) is a 23mm diameter, top-fill tank with exceptional flavor and engineering. Our favorite features are the no-mess coil replacement procedure and the intuitive filling method which effectively prevents flooded, gurgly coils.
The Zenith MTL Tank uses its own proprietary Zenith coils and comes with both a 1.6 ohm MTL coil, rated for 10 to 14W and a 0.8 ohm MTL coil, rated for 15 to 18W. Changing coils in the Zenith tank is a joy thanks to smart engineering: the old coil head comes out cleanly from the base of the tank, even when full!
The Zenith holds 4mL of e-liquid and is fillable via a nice-sized fill port at the top of the tank. Filling the tank is a pleasure thanks to a design which causes the liquid channels to close when the user unscrews the top cap to refill, thereby avoiding the usual flooding that comes with top-fill tanks.
