A convenient top fill system ensures the tank doesn’t need to be removed from the device to refill, simply unscrew the top and fill with e-liquid as required. A fully adjustable airflow at the bottom of the tank can be tweaked to suit personal preference, from a tighter MTL draw when using the 1.2ohm coil to restricted DL when the 0.6ohm option is used.
The TECC Specter tank would be an ideal choice for vapers who want to use high strength e-liquids, including nic salts, but would also be suited for use with an even wider range of e-liquid types.
