Innokin Tanks
Innokin tanks are built for mouth to lung vaping on the Zenith coil platform. The Go Z combines the simplicity of a pod with the durability of a tank, and the Zenith Minimal is a compact 2ml tank that also handles direct to lung vaping. Both fit a 510 connection and take Innokin Z coils.
The Go S is a 2ml disposable tank with a fixed 1.6Ω mouth to lung coil. You refill it as normal, then replace the whole tank when the coil wears out.
