A stylish and compact pen device, the Endura T20-S from Innokin features a 1500mAh in-built battery and Innokin's Prism-S tank. The Prism S is the next generation tank and coil system, focusing on pure flavour and throat hit. With restricted draw but 0.8 Ohm coils, the Endura is an ideal first step into Sub Ohm vaping.

Sleek and simple by design, the Endura T20-S is a kit designed especially for those looking to move into Sub Ohm vaping from a mouth to lung device.

A 3 coloured LED allows you to monitor the battery life with a traffic light like system. Green is full charge, yellow is when it's on half charge and red is when you're out of power. The 1500mAh battery will give you some decent vaping hours and thanks to the passthrough technology you will still be able to continue to vape while you're charging. Just plug in the micro-USB cord that comes in the kit and you'll be back at full capacity in no time. It has the usual safety features you'd expect like battery overcharge protection, short circuit protection and over-discharge protection.

When you run low on juice the top fill system makes refilling easy, just unscrew the top cap and pour your liquid in the gap around the coil. The 0.8 Ohm coils are a good balance between a higher resistance and Sub Ohm, giving both flavour and vapour production without being too intense for new Sub Ohm vapers.

The coils are easy to change, you just need to invert the tank, unscrew from the base and pull out the old coil. Drop a new one in, let the liquid soak for a while and you're ready to vape again.
