Innokin Endura T18E Kit: The No-Nonsense MTL Vape Pen
Quick verdict: the Innokin Endura T18E Kit is a refillable MTL (mouth-to-lung, a tight cigarette-like draw) vape pen with a built-in 1000mAh battery and a 2ml top-fill tank, priced at £18.88. It runs a fixed 14W with one button, no menus and no airflow ring, so it just works. Best for new switchers and anyone who wants a simple, pocket-sized pen. Not ideal if you want big clouds, fast charging or adjustable airflow.
The Endura T18E is the stripped-back member of Innokin’s long-running Endura pen range. Where the T18 II adds power modes and the T22 moves to a chunkier box shape, the T18E keeps it deliberately plain: fill it, press, vape. That simplicity is exactly why ex-smokers keep coming back to it, and why it remains one of the most recommended first vape pens in the UK.

Pick Your Draw: MTL Only
The T18E is built for one job and does it well: a tight MTL draw that feels like a cigarette. There is no airflow ring and no DTL (direct-to-lung) option, which keeps things foolproof for new vapers. If you have only ever used a disposable, this is the same tight inhale you are used to, just refillable and far cheaper to run.
Key Features
One-button simplicity with no settings to learn or menus to scroll.
Fixed 14W output for a consistent vape from first puff to last.
2ml top-fill tank so you refill from the top without removing the tank.
Pass-through charging means you can vape while it charges.
Pocket-friendly pen shape in nine colours, with a vape stand in the box.
Coils and E-Liquid Pairing
This is the part to get right. The T18E uses the 1.5Ω Prism T18E coil, and it pairs best with 50/50 e-liquid or nic salts. The high-resistance 1.5Ω coil is made for thinner, PG-based juice, so avoid high-VG shortfills, which are too thick to wick properly and will give you dry hits. Match it with a 50/50 e-liquid or a 10ml nic salt for the smoothest result.
When it is time to restock, you need the Innokin Endura T18E Replacement Coils. To get the most from each one, prime it first: add a drop of e-liquid onto the cotton, fit it, fill the tank, then let it sit for five to ten minutes before vaping. Skipping this is the fastest way to burn a coil.
Battery, Coil Life and Running Cost
The built-in 1000mAh battery is sized for a pocket, not a power station, so it gives most users a day of light-to-moderate use before a recharge. Charging is over Micro-USB, which is slower than modern USB-C kits, so an overnight or desk-side top-up suits it best. Pass-through charging means you are not stuck waiting.
A Prism T18E coil typically lasts around seven to ten days, though sweeter, darker juices clog coils faster. A five-pack of coils covers most users for well over a month, which is the real saving versus disposables: you are buying coils and juice, not a whole new device every few days.
Compatibility and Refills
Coil naming in the Endura range trips a lot of people up, so here is the clear version. The Prism T18E 1.5Ω coil fits the Endura T18E, the T18 II and the T18 II Mini, and it also works in the Innokin M18 pod. It does not fit the standard Endura T18 or T22. The older standard Prism coil looks almost identical but is physically larger, so if you buy “T18 coils” by mistake they will not seat. Always pick the coil with the E on it. If your glass cracks or the tank wears out, you can fit a fresh Endura T18E replacement tank rather than replacing the whole kit.

Switching from Disposables?
If you have moved on from disposable bars, the T18E is one of the gentlest landing spots. The tight MTL draw feels familiar, the single button means there is nothing to learn, and the only new habit is refilling a 2ml tank and swapping a coil every week or so. You keep the cigarette-like inhale you are used to, lose the throwaway cost, and pick your own flavour and nicotine strength.

Innokin Endura T18E FAQ
Which coils does the Innokin Endura T18E use?
It uses the 1.5Ω Prism T18E coil. The same coil fits the Endura T18 II, T18 II Mini and the Innokin M18 pod. It does not fit the standard Endura T18 or T22, so always choose the coil marked T18E.
Do standard T18 coils fit the T18E?
No. The standard T18 and T22 Prism coil is larger and will not seat in the T18E tank, even though it looks almost the same. You need the smaller T18E version. Buying the wrong one is the most common mistake with this kit.
What e-liquid should I use in the Endura T18E?
Use 50/50 e-liquid or nic salts. The 1.5Ω coil is made for thinner, PG-based juice and gives a tight MTL draw. Avoid high-VG shortfills, which are too thick to wick and cause dry, burnt hits.
How do I fill the Innokin Endura T18E?
Twist or lift the top cap to expose the fill port, tip your e-liquid down the side of the glass, then close it. With a new coil, prime it first by adding a drop to the cotton and letting it sit for five to ten minutes.
How long does the T18E battery last?
The built-in 1000mAh battery gives most users a day of light-to-moderate vaping. It charges over Micro-USB, which is slower than USB-C, and supports pass-through so you can vape while it charges.
How long do the coils last?
A Prism T18E coil usually lasts around seven to ten days. Sweeter and darker e-liquids shorten that, so if flavour drops off or you taste burning, fit a fresh coil and prime it before use.
Why is my T18E leaking or flooding?
Flooding is usually an over-filled tank, a coil that is not primed, or using juice that is too thin. Fill just under the top, seat the coil firmly, use 50/50 juice, and take steady draws rather than short sharp puffs.
