The Innokin GO Z Tank is conveniently designed to deliver a quality MTL vape. Designed to be used with the Innokin GO Z pen kit, it screws to the top of the battery. The filling system provides a simple and mess free way of topping up the tank with e-liquid. Simply slide the top to reveal the e-liquid inlet. Push the tip of the e-liquid bottle through the silicone seal and fill. This adds extra protection from leakage. The top fill system also means it doesn’t need to be removed from the kit when adding vape liquid. The airflow can be adjusted by twisting the ring at the base of the tank to increase or decrease the size of the air inlet. The precise airholes provide a restricted draw suitable for MTL vaping. Plus, the 1.6ohm Innokin Z coil provides great flavour from 50/50 e-liquid and nic salts.
