The Innokin Endura T20-S is a slim, pen style starter kit designed for a simple mouth to lung vape that feels close to smoking. It pairs a 1500mAh built in battery with the Prism-S tank and 0.8Ω coils to focus on clear flavour and a satisfying throat hit rather than big clouds.
A straightforward top fill tank, easy coil changes and a three colour battery light keep day to day use simple. You can even vape while it is on charge thanks to pass through charging. If you are moving away from cigarettes and want a tidy, no fuss kit, the Endura T20-S is built with that exact role in mind.
Product Features
1500mAh Built In Battery
The 1500mAh internal battery is designed to give you several hours of use between charges. Pass through technology means you can carry on vaping while the device is plugged in, which helps if you forget to charge in advance.
Easy Top Fill System
When the tank runs low, refilling is simple. Unscrew the top cap and pour your e liquid into the gap around the coil, then screw the cap back on. No need to remove the tank from the battery for everyday refills.
Tri-Colour LED Battery Indicator
A three colour LED shows your remaining battery level. Green means high charge, yellow indicates around half battery remaining and red tells you it is time to recharge.
Simple Coil Changes
Swapping coils is straightforward. Turn the tank upside down, unscrew the base and pull out the old coil. Drop a new coil in, reassemble the tank and leave it a few minutes so the liquid can soak in before you start vaping again.
Sleek Design
The Endura T20-S has a clean, timeless pen style look and a tighter draw suited to MTL vaping. It is aimed at people moving away from smoking who want something familiar, compact and easy to use.
Prism-S Coils Included
In the box you get two 0.8Ω Prism-S coils. This resistance offers a good balance of flavour and vapour with a restricted draw that is not overwhelming for new vapers, while still giving enough performance to feel satisfying.
