Previous Endura Models have lots of fans who use them to stop smoking and this is a wonderful update to the range. Being designed for MTL vapers and focusing on flavour and throat hit this should appeal to smokers and ex-smokers primarily. A lot of long term vapers also use the MTL method and creating house fog isn’t really for them – flavour and throat hit are a priority. The coil simply pushes into the tank – make sure to align the cut outs and push the coil firmly into place. An old coil is removed by simply pulling it out from the tank.

The Endura T20-S comprises of a 1500mah battery unit with a Prism T20-S tank. The tank is a top fill. Later models of the tank and starter kit have a 1.5ohm coil included – this wasn’t in my kit so was unable to review this. The Prism T20-S Tank Performance I used an 80% VG 6mg nicotine E- liquid (I have added additional nicotine to make this 12mg nicotine strength.) As the 0.8Ohm is a sub ohm coil these generally need lower nicotine levels and can handle higher VG liquid. But these particular coils require less wattage running to them to perform so a 6mg/12mg nic strength isn’t too harsh. My friend owns just the T18 tank on its own and uses it on a mod. So for those who want to just buy the tank on its own – I put this tank on my Eleaf Pico to test its performance. Now from a really shallow perspective this isn’t the prettiest device I have used. The Endura T18 is a beauty and the Joyetech Exceed D19 is stunning. This, for me, isn’t.Unscrew the top cap (not the mouthpiece which I did accidentally a few times!) Grip the top cap part of the tank to unscrew. The Endura Prism T20S tank is also available as a separate item for use on other batteries or vape mods.

I have also tried the tank on another mod on its own to see how the tank performs. 0.8 ohm Prism S Coil I haven’t got this battery to run out yet – at 7.5 hours the light is still showing green (above half charge) so I hope that gives you an idea of the battery life. What I Like The Innokin Prism S 1.5 Ohm coil produces the least amount of vapour, capable of being used between 15 - 18W. For increased flavour and a slightly larger amount of vapour, we recommend the 0.8 Ohm or 0.9 Ohm coil. However, the 0.9 Ohm version also has a mesh build, meaning that you'll experience a more intense flavour from your e-liquid thanks to being heated up faster. Whichever version of the coil you choose, we suggest either a 50/50 e-liquid or high PG eliquid. If you shop around you can get 6mg 80% VG E-liquid I have a few different brands with this strength. My favourite is the Stika Bombz fruit salad which comes in 10ml bottles and 6mg strength. Sadly due to the TPD regulations any bottles bigger than 10ml will be usually 0% nicotine. I tend to stay away from these myself.The top cap and mouthpiece unscrew easily and the tank is extremely easy to dismantle if you want to wash it out or change the glass. A tip I found with my friends T18 tank, is to always make sure the drip tip is fully pushed into the top cap. The bottom of the drip tip makes a seal with the centre of the coil. If the tip isn’t fully pushed in this can cause liquid to enter the centre of the coil which can result in spitting and leaks from the bottom pin of the tank. This is a definite MTL coil, quite restricted airflow – but it could do with a slightly tighter draw to satisfy a smoker. Due to their handy push-fit design, it's easy to change the Prism S coils in your EZ Watt or Endura T20-S Kit. To change the coil you will need to empty the tank – so either decant the liquid into a suitable container or pour onto a tissue and discard.

A 0.8ohm coil is of course a sub ohm coil but it runs at a lower wattage than what you would use with a ‘true’ sub ohm tank that is designed for Direct to Lung vaping. For instance, I use a sub ohm tank with a 0.4ohm coil at 30-40W. I did find however I kept pressing 5 times to turn on and off as this is the norm for most E-cigs! How To Fill The Prism T20-S TankSimple battery charging- connect the small end of the supplied USB cable to the side of the battery and the larger end to a USB outlet port. The light on the button goes out when it is fully charged. In The Hand As the T20S runs lower wattage a 12mg nic won’t give ‘as much’ of a hit as a true direct to lung/sub ohm tank. As such I would say if the 6mg nicotine isn’t doing it for you then a 12mg nic will be OK with this and well worth trying out. The instructions are poor really. I think this area would need to be improved upon to help first time vapers get to grips with this.

Innokin have brought us some of the best vape pen devices in the past including those with the ‘Endura’ name. There is the Endura T18 and the Endura T20. Do not get confused as the T20-S is very different from the T20 and does not use the same coils.

In the 5 hours since I got this up and running, I haven’t smoked a single cigarette – the flavour and throat hit are perfect. Oh and the battery is still showing above half charge in this time! What I Dislike The tank top cap is difficult to grip and unscrew as there is little to grip onto. You have to remove this every time you want to refill so it does get a bit annoying. I found myself having to use my sleeves over my hands to unscrew this. Final Review VerdictI think as a starter or intermediate kit is where this excels. A smoker would find this very satisfying and it totally performs in the same tradition as its predecessors the T18 and T20 – being a great starter kit to advise someone to buy. Innokin Prism S coils tend to last between 1-2 weeks, though this can vary depending on your e liquid and how frequently you vape. When it's time to change your coil, you will notice a deterioration in the flavour. If your vape tastes burnt, it's definitely time to change the coil! How to Change Your Coil The Innokin Endura T20-S starter Kit includes everything apart from E-liquid to get you up and running. Plus some spares to help you maintain it. Really simple operation, press the fire button to vape – no other settings or adjustments to contend with. Another tip is to remove the drip tip when installing a coil – this makes sure that the coil is fully inserted into the tank when you secure it. Flavour & Cloud Production
