What is Electric Tobacconist Returns Policy?

The Electric Tobacconist Ltd abides by the Distance Selling Act (2000). 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. This excludes e-liquids, clearomizers and disposables.

Can I replace the coils on this clearomizer?

Yes, this product has a replaceable coil, so once the coil needs replacing, you do not need to buy a whole new clearomizer. Click here to see our replacement coil pack department.

How long will this clearomizer last before it needs replacing?

Glass clearomizers can last for anything up to six months as long as it is kept well protected; plastic clearomizers will have a much shorter lifespan. The coil within it, however, will last approximately 2-5 weeks depending on use. After this time it will 'burn out' (ie reach the end of its lifespan). After your coil has burnt out, you will either need to change it (if spare coils are included), buy a new clearomizer (if the clearomizer is disposable), or buy a pack of replacement coils. 


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.


What is Sub Ohm vaping?

Sub-ohm simply means the resistance of the atomiser coil is below 1.0 ohm. Sub-ohm coils are generally larger and therefore can utilise more power and cover a greater area of wick - a combination which results in massive vapour production. A high-powered device paired with a sub-ohm tank is required for sub ohm vaping.

"Direct-to-lung" is the suggested vaping style for most sub-ohm devices (as opposed to "mouth-to-lung" -  i.e. how a traditional cigarette would be smoked).

High-VG (over 60% VG), low nicotine (6mg or lower) e-liquid is recommended when using sub-ohm devices.


What is the warranty on clearomizers?

Clearomizers are covered by a strict 7-Day warranty from order date as they are consumable oral products. Clearomizers that have been over tightened, dropped and crushed are not covered by this warranty.

Innokin Endura T20-S Tank Reviews

Great tank for great wee vape pen. Never had any problems with this at all. Only replaced as I dropped my first one - hard!! Small crack in the glass panel. But it did hit a tile floor with serious whack! Love this vape pen, all accessories hardwearing and hardworking.

7th June 2022 - Frances Porter

Bought to replace a T22 which was leaking. The smaller size isn't an issue but the refill cap is plastic and is more difficult to thread than the metal one found on the T22.

No leaking and the spare O rings will come in useful. Very happy with the tank.

22nd September 2021 - Ian Gale

Love this little T20 vape. Excellent quality and has lasted and lasted. Can get 'parts' for it, but i bought two for convenience. Great, brilliant price.

Slight problem with delivery but that was DPD's fault, not Electric Tobacconists. However, I cannot fault the customer service from ET. It was exemplary. They re-dispatched the tank to me in double-quick time, were always very polite and prompt in correspondence, and the tank itself is excellent! I am very impressed!

23rd April 2021 - Lynne Kerr

I've 2 T20s and very happy with them for the last 2 years or so and got this to replace a tank that got broken.
Attached the battery, filled up, left it to soak in, but an hour later the T20 was standing on a pool of oil and the tank was empty! Replaced the coil and refilled. Was ok after that.
An isolated case I'm sure, but not happy I lost a tankful of oil and a coil.

12th April 2021 - Geoff Gibbs

Brilliant 2nd tank

23rd March 2021 - Garry Cunningham

Red tank not that colour matters all do the same , great value works really well would defo buy again if needed highly recommendable

13th March 2021 - Emma Norton

Excellent product.

10th January 2021 - John Silcock

The T20S is a great vape compared to others I've tried, such as the Blu and Logic pod kits. It was also instrumental in weaning me of cigarettes ,and the total cost of ownership is lower in the long run than pods. It's robust, gives a great hit and the 1,500 mAh battery lasts all day. If it has a weak spot, it's the tank. It's very easy to get the plastic mouthpiece cross-threaded with the metal tank body. Once this happens, it's only a matter of time before the mouthpiece won't screw in any more and you need to buy a new tank.

29th December 2020 - Peter Dykes

Very pleased with this tank

17th June 2020 - Diana Clayton

Brilliant tanks for mtl easy to fill and use, I've bought 3 of these tanks :)

8th May 2020 - Michala Oakes

Yet again delivery first class very pleased with product/tank again keep up the good work through troubled times

10th April 2020 - Mike Walton

Bought this as a replacement for when I'm cleaning the original one, worked great from the start no problems, like the packaging.

9th April 2020 - Stephen Hayward

This is a second time round replacement, though the first I've bought from yourselves, hope it lasts a bit longer than the the first two. Delivery timescale was outstanding considering the present climate. Well done

4th April 2020 - Brian Grainger

Arrived next day. Fantastic service

29th January 2020 - Helen Beattie

Looks good and fitted no problem but after a month has now one section of glass has crazed over

18th November 2019 - William Brown

Ordered in red not black. Tank is great as uses lower watt coils so better for mtl

30th October 2019 - Michala Oakes

As expected

exactly as described and a good vape, the only downside is the plastic top,

23rd May 2019 - Phil Cogan

Exact replacement. Just make sure you tighten everything before filling up the tank!

29th July 2018 - Gavin Jones

Decent vape as always with innokin but seriously messy to refill with an internally threaded cap. Tired of the mess and juice wastage so I've ditched these for the t18e tank - much more sensible design, great flavour and no mess!

9th May 2018 - David Hornsby

very poor tank, draws liquid into your mouth, spits and gurgles, pass it by there are better tanks out there.

30th April 2018 - Bob Ohara

Great MTL tank and stylish too, with the red I purchased having a textured rubberised feel. Easy to top fill, no leaks and the coils are reasonably priced and are lasting 2 to 3 weeks. Was recommended this tank by electric tobacconist as an upgrade to the T18 and its been brilliant, works great with the T18 battery and 1.5 coil.
