About the Innokin Endura T20-S

A vape pen starter kit for flavour fiends, the Innokin Endura T20-S Starter Kit packs a lot into a compact pen-style design. 

The 1500mAh internal battery gives you a consistent 18W of power, and features passthrough technology to allow you to vape while charging alongside a range of integrated safety features. A three-colour LED lets you keep an eye on your remaining battery life; when you need to recharge, you can use the Micro USB cable included in the kit and the LED will display your charging status.

The Endura T20-S Starter Kit also includes the 2ml Innokin Endura Prism T20 S Tank, an outstanding tank for mouth-to-lung vapers looking for uncompromising flavour. The Prism-S Tank delivers pure flavour and a truly satisfying throat hit, and features a simple top-filling mechanism for hassle-free e-liquid refills: just unscrew the top cap and drip your e-liquid down the sides of the tank. The 0.8ohm Prism-S Coils included are optimised for the perfect draw with the ideal amount of airflow, while the organic cotton wicking provides even deeper, more intense flavour. The Innokin Endura Prism T20-S Tank is 510 threaded, and can be taken apart easily for straightforward cleaning.

The Innokin Endura T20-S Starter Kit is a great mouth-to-lung starter kit, offering a straightforward introduction to sub-ohm vaping or making a fantastic, portable addition to a larger collection. If you’re looking for a flavour-focused mouth-to-lung vape pen, the Endura T20-S might be exactly what you’re looking for. Available in classic black and silver finishes, or a high-quality rubberised finish in red, grey, blue or purple.

If, once you have purchased items from us, you decide you no longer want them, then you have 28 calendar days in which to return them and we will refund them in full within 28 days of the cancellation date (including any postage and packing paid) as long as the packaging remains unopened.

What's the difference between a vape kit, a vape pen, an all-in-one and a pod mod?

Names are often manufacturer-led, but in general, there's not really any difference between a vape pen and a vape kit, except a vape pen tends to look more like a pen! 

A pod mod tends to be the more modern version of the above, but whereas vape kits and vape pens have clearomizer tanks that need refilling, pod mods have pods (capsules) that are pre-filled (either by the user, or as they come) and are taken off and replaced as and when needed.

All-In-One (AIO) kits are similar to vape pens but rather than using removable tanks, the battery and tank is one combined unit.

How long will the battery last between charges?

The length of time your ecig battery will last depends on how often you use it, but as a guide, this battery should allow 12-14 hours of vaping before needing a recharge.

How do I fill a 'top fill' clearomizer?

To fill a 'top fill' clearomizer with e-liquid, simply unscrew the mouthpiece at the top, now tilt the unit to a 45% angle and pour the e-liquid into the barrel against the inside wall of the clearomizer. The aim is the coat the inside wall with e-liquid. Avoid getting it down the central metal barrel (aka the breathing or central pipe) as this may cause it to leak.  Do NOT over fill your clearomizer.


How do I maintain an e-liquid-style kit?

E-liquid-style kits of this type require the following upkeep:

1. E-Liquid refills - one bottle of e-liquid can last anything from a couple of days to a whole month depending on the size of the bottle and the amount you use it. Click here to see our e-liquids range. If you have a high powered sub ohm kit, you'll want to use an e-liquid with a VG content of 60% or greater. If using a low-power kit you'll want to use liquids with more than 50% PG

2. Replacement batteries: Once you notice the performance level and vapour production begin to diminish, you will also need to replace the battery. Batteries on this type of kit last anything from two to three months (and sometimes longer, depending on use). Replacement batteries can be bought here

3. Replacement clearomizers and coils: The clearomizer tank used to house your e-liquid has a small coil within it. This coil will burn out after anything from a few days to two weeks. At this point you will notice that either hardly any vapour is being produced, or there is a burnt taste to your e-liquid. If your clearomizer is of the disposable variety, you will need to replace the whole unit at this point. If it has replaceable coils, you will need to buy a new pack of coils.

A list of disposable clearomizers can be found here

A list of clearomizers with replaceable coil option can be found here 


What is the warranty on this product?

This product comes with a 90 day warranty from the date of order. However, this does not cover misuse, damage or standard wear and tear.

Can I use this kit with high-strength nicotine e-liquids?

Yes, when used with coils above 1.0 ohm, this e-cigarette can be used with e-liquids that contain higher amounts of nicotine (i.e above 12mg).

This is my 3rd T20-S. I like to have a spare, but lost one.
So this one arrived and primed it before use.
However, on starting up, tasted horrible - burnt taste.
Changed the coil, and it was fine after that.
NB - I think if a 1st time vaper had got this particular one, it would have put them off vaping for good!

Been using t18e and decided to give this one a try. Great piece of kit, lovely vape, easy to use nice to hold will definately buy another one love it

This is the best device I've tried. I have 2 of them now, a blue one and a rainbow coloured one. Really easy to use and gives great taste and vapour. Coils are inexpensive and easy to change, they last well over a week for me. The pen feels well made.
Only downside is no airflow adjustment, but it is perfect for me. Great mouth to lung device!

19th August 2018 - Amy Reeves

Absolute brilliant product !

11th August 2018 - Jamie Clattenburg

After trying various pen types I decided to spend a bit more and find out if i could get one which didn't leak too easily and this is the one - no leaks at all (unless you forget to check and fully screw in the coil when you first fill it :-) solid build and great traffic light power indicators. The 3 press facility for locking the pen is easier to operate than a 5 press.

Steer well clear. Leaked juice everywhere. Terrible design. I returned it and still no refund 3 weeks later. So now I'm out of pocket. Id give no stars if I could

3rd August 2018 - MR JAMES M HALE

Fantastic product easy to use,supports high vg my now number 1 go to product, would definitely recommend for a mtl device

15th July 2018 - Lisa Orr

Better design on new model less leakages and better vapour

10th July 2018 - John Tabis

Very good, just what I was looking for.
Vapes better now I've taped up one of the air holes. - Was too much air intake before.
Have ordered another as a spare as replacement batteries seem unobtainable.

2nd July 2018 - Geoff Gibbs

My first vape pen was a Innokin T18e which I have to say I am still very happy with, but I was curious what sort of improvement there would be going to the T20-S and I have to say I'm pleasantly surprised.

Compared to the T18e, the 'airyness' is roughly the same, although as I prefer a tighter draw I have used a bit of nail varnish to block one of the two air intake holes and it really makes a huge difference when inhaling.

Although I never really had any issues using higher VG liquids with my T18e, the T20-S with its 0.8ohm coils is definitely better for use with these thicker liquids (although there are 1.5ohm coils available for use with the thinner 50/50 liquids if you prefer them)

Overall though I am very impressed with the T20-S. I think the packaging and presentation is very impressive, certainly a very similar quality and style to how an Apple product would be packaged. The product itself is very high quality and designed well and it's easy to fit new coils and obtain replacement parts so I can see myself as a very happy customer for some time to come!

I like the Innokin T20-S. I have some other Innokin stuff, a T22 which gives a nice smoke at optimised 14W and a Cool Fire Mini with a T18 tank, so although adjustable I keep at the same 14Wsetting, V-nice. These tanks share the same coils. The T 20-S is fairly standard looking with a small 2ml tank but they have cranked it up a bit from the T-20 which is 13W. The T 20-S is 18W optimised with 1500mah battery so a little extra oomph in the puffing department. Gives a decent cloud of smoke. I have watched several reviews of the T 20-S on YouTube and a regular comment is that it might be a little, "airy", for us trying to give up fags and go to vape. Meaning not quite enough density of vapour to replicate a fag like smoke and more of a direct to lung effect. It seems to work well in both ways. I see what they mean, the vapour is a bit thinner with air, but there are 2 air intake holes on the T20-S which when you hold it to vape, one of them is easy to block, or partially block with your finger, hence less air going in and more of a thicker intake. Innokin seems good quality to me, no leaks, the T 20-S coils apparently don't fit anything else so that's a negative, otherwise think it's a good'un.

so big if it smaller , but it work very well

18th February 2018 - Mohamad Kamal Allabwani

Good product, happy with it and so far no leaks

16th February 2018 - Tim Van Vlymen

I have two of these one for my nicotine fix! And the other for CBD vapeing. Brilliant, easy to use and no leaking would highly recommend.
