The Endura T20s tank is the replacement tank for the T20s and the EZ-Watt. The T20s is a tank and coil system that is focused on pure flavor and throat hit, this MTL tank provides an exceptional experience in how it vaporizes e-liquid. With a 2.5ml capacity, you can enjoy vaping for the whole day. The Prism-S coil will let you taste flavors like never before! With two coil options (1.5 a tighter draw, and the 0.8 for the loose easier draw), you can find the right one for your vaping needs. Just unscrew the cap and fill it from the top. Enjoy the optimized draw for just the right amount of airflow and precision vaporization.
