Innokin Endura T18E overview: a simple pen-style starter kit

The Innokin Endura T18E Vape Starter Kit is a refillable, pen-style device built for mouth-to-lung (MTL) vaping, the tighter and slower draw that most people who are moving away from cigarettes find familiar. It belongs to Innokin's long-running Endura family, a line that has always leaned towards straightforward hardware: a slim battery section, a small top-fill tank and a replaceable coil, with very little to configure. If you have looked at screens, wattage dials and adjustable airflow rings on other kits and felt that it was all too much for a first device, the T18E is aimed squarely at you.

The headline specifications are easy to hold in your head:

• Battery: built-in 1000mAh rechargeable cell, charged over USB
• E-liquid capacity: 2ml, which is the maximum tank size allowed for nicotine vaping devices in the UK
• Coil: Prism T18E, 1.5 ohm, a conventional wire-and-cotton coil designed for MTL
• Filling: top-fill, so you can refill without removing the tank or the coil
• Operation: built around inhale-to-vape simplicity, with no menus or modes to learn
• Style: slim pen format that sits comfortably in a pocket or a bag

This is a refillable kit, not a disposable. That matters in the UK for two reasons. First, single-use vapes were banned from sale in Great Britain from 1 June 2025, so refillable and pod-based systems like this one are now the mainstream route for anyone who wants a grab-and-go device. Second, a refillable kit lets you choose your own e-liquid and nicotine strength, within the UK cap of 20mg/ml that applies to every nicotine e-liquid and to the liquid sealed inside any pod or disposable.

What the kit does not try to be is a feature-packed enthusiast device. You will not find adjustable power, a display, a Bluetooth app or sub-ohm cloud production here. What you get is a modest, predictable setup that does one job: delivering nicotine and flavour in a way that feels close to smoking, from a device you can learn in a single sitting. The rest of this guide walks through how it performs, who it suits, how to set it up and look after it, and where it sits against comparable kits, so you can decide whether it matches what you need.

A quick note on contents: kits are typically supplied with the device, a pre-fitted Prism T18E coil, a USB charging cable and a printed manual, but packaging can change between batches, so check the product listing for the exact contents of the box you are ordering. Vaping products are for adults aged 18 or over, and they are intended for smokers who want an alternative, not for non-smokers or young people.

Performance and puff delivery

The performance of the Endura T18E comes down to three numbers: a 1.5 ohm coil, a 1000mAh battery and a 2ml tank. Put together, they describe a low-power MTL device, and it behaves like one. The draw is snug rather than airy, the vapour is modest and cool-to-warm rather than hot and dense, and the throat feel is closer to a cigarette than to the big lung-fillers you see on enthusiast forums.

It is worth doing the sums so you know what to expect. A 1.5 ohm coil running from a lithium-ion battery that swings between roughly 3.7V and 4.2V works out, by Ohm's law, to somewhere around 9W when the battery is at a nominal charge and a little under 12W when it is full. That is a low power band by modern standards, and it is the right band for a 1.5 ohm MTL coil: enough heat to vaporise liquid cleanly, not enough to scorch the cotton or turn the vapour harsh. Because the output is not adjustable, there is no way to push it into territory the coil was not designed for, which is a feature for beginners rather than a limitation.

On puff count, any figure is an estimate because it depends on how long you draw for and how thick your e-liquid is. Treat the following as reasoned ballpark numbers rather than laboratory results:

• A full 2ml tank is likely to give somewhere in the region of 400 to 600 puffs at a typical three-second MTL draw
• A full battery charge is likely to cover roughly 250 to 350 puffs before it needs topping up
• In day-to-day terms, a light vaper may stretch a single tank across a day or two, while a heavier user will refill once or twice daily

Notice that a charge and a tank are roughly matched. In practice most people end up charging the device about as often as they refill it, which makes the routine easy to remember: refill, charge, carry on.

Nicotine delivery is the other half of performance. MTL devices at this power level are well suited to nicotine salt e-liquids, which are smoother at higher strengths than traditional freebase nicotine and are absorbed quickly, giving many smokers the satisfaction they miss when they first switch. With a salt liquid at 10mg/ml or 20mg/ml, the T18E gives a throat feel that former smokers tend to find closer to what they are used to. With freebase liquid at 6mg/ml or 12mg/ml, the delivery is gentler and the throat hit is a little sharper, which some people prefer.

Where the T18E will not satisfy you is if you want volume. Expect a small, tidy cloud. If you want to blow large plumes, a sub-ohm kit is the better fit and this device is not trying to compete there.

Flavour profile and what to expect from your e-liquid

The Endura T18E has no flavour of its own, because it is a refillable device. What it does influence is how your chosen e-liquid tastes, and the character it adds is fairly consistent: a rounded, moderately warm flavour with good definition on the main notes, because a 1.5 ohm cotton coil at low power does not bury a recipe under heat or sheer vapour volume.

Here is how different liquid styles tend to come across on a coil of this type:

• Tobacco and tobacco blends: these are a natural match for low-power MTL, with the draw and throat feel doing a lot of the work of reminding you of a cigarette
• Fruit and ice: clear, crisp and easy to identify, although very heavy menthol and cooling agents can feel sharper at 20mg salt strengths
• Menthol and mint: a popular pairing, since the cool sensation on a snug draw tends to feel more pronounced than on an airy sub-ohm setup
• Desserts, custards and bakery: they work, but sweeter recipes are more likely to build up residue on the coil, so expect to change coils somewhat more often
• Drinks and sweets: these are rendered cleanly, with the more delicate top notes still coming through at this power level

VG and PG ratio matters here. The Prism T18E coil is designed for thinner liquids, and a 50/50 or similar balanced blend wicks reliably. Very thick, high-VG juices of 70VG and above can struggle to soak into the cotton quickly enough at this power, which shows up as dry or muted puffs, so check the label before you buy. Most nicotine salt e-liquids are made at a balanced ratio and are comfortable choices.

New coils need a short run-in period for flavour to settle. After fitting a fresh coil, let it soak for five to ten minutes before your first puff, and take a few gentle puffs rather than a long hard one. The first tank through a new coil is often a touch muted, and the flavour then comes up to its normal level over the next few refills before gradually fading as the coil ages.

An honest caveat: low-power devices have a ceiling on flavour intensity. If you are used to powerful, high-wattage vapour, the T18E will seem restrained. That restraint is the point of the design, but it is worth setting expectations so you are not disappointed in the first few days.

If you want to change flavour, you can. Empty the tank, rinse it with warm water, dry it fully and refill. Some people keep a dedicated coil for strong flavours such as menthol or aniseed, because those profiles can linger and colour the taste of whatever follows.

Design and build quality

The Endura T18E is a pen-style device, which means a slim, cylindrical body that you hold much as you would hold a cigarette or a marker pen. That form factor is the main reason this style of kit remains popular with smokers who are switching: the hand position, the draw and the length of the device all feel natural. It slips into a jacket pocket or a bag side compartment without any bulk, and it is light enough that you will not notice it in a trouser pocket.

The device is made up of two main parts that screw together: the battery section, which holds the 1000mAh cell, the electronics and the USB charging port, and the tank, which holds the coil and 2ml of e-liquid. Because the battery is built in, there are no removable cells to buy, source or store, and you cannot put the wrong battery in. The trade-off is that when the battery eventually wears out, the whole unit has to be replaced, so it is worth treating the battery well and charging it sensibly.

Points that matter in everyday use:

• Top-fill design: you can refill without taking the tank off, which cuts down on mess and makes it easy to top up on the move
• Clear tank section: you can see the liquid level at a glance, which helps you avoid running a coil dry
• Single airflow setting: there is no adjustable airflow ring, so the draw is set by the factory and tuned to match the 1.5 ohm coil
• Compact mouthpiece: a standard MTL-style drip tip that is comfortable to hold between the lips
• Colour finishes: Innokin typically offers the Endura range in several colours, so availability varies by stock, and the listing shows what is currently available

Build quality is in line with what you would expect from an established mid-market brand. Innokin has been making vape hardware for many years, and the Endura line has a reputation for working reliably day to day rather than for flashy finishing touches. As with any pocket device, the finish on the body can pick up scuffs if it shares a pocket with keys or coins, so a small pouch or a separate compartment keeps it looking tidy.

The lack of adjustability will frustrate some people and reassure others. There is nothing to break, nothing to misconfigure and nothing to accidentally change in your pocket, which makes the T18E a sensible first device and a reasonable backup device for a more advanced user.

One practical design point: because the tank is small and the airflow is tight, always keep the device upright when it is not in use. Lying a pen-style tank on its side in a bag can let liquid creep towards the airflow channel, particularly if the tank is filled right to the top.

Battery life and charging

The built-in battery is rated at 1000mAh. At a nominal 3.7V, that is around 3.7 watt-hours of stored energy. With a coil that draws roughly 9 to 12 watts, and allowing for the losses that any battery and circuit introduce, you are looking at around 14 minutes or so of total firing time per charge, which equates to a few hundred typical puffs. That fits the 2ml tank well, as discussed earlier, and for most people it means a single charge per day.

Charging is done via the USB port using the supplied cable. A few practical tips that apply to any device with a built-in lithium-ion battery:

• Use a sensible charger: a standard 5V wall adapter or a computer USB port is fine. Avoid unbranded fast-charge bricks of unknown origin
• Expect a charge time of a couple of hours: the exact time depends on the charger and how depleted the battery is, and the manual gives Innokin's own guidance
• Do not leave it charging unattended overnight: especially on soft furnishings, and never cover the device while it charges
• Unplug once it is full: modern devices include protection, but you reduce wear and risk by not leaving a full battery on charge for days
• Keep it out of heat: a hot car dashboard or a radiator shelf is bad for lithium-ion cells
• Stop using it if it is damaged: swelling, a cracked casing or unusual heat during charging mean the device should be retired

Charge it fully before the first use. A full first charge is a simple habit that gives you a clear baseline for how long a charge lasts on your own pattern of use.

In daily use, expect the vapour to feel marginally softer as the battery drops towards empty, because a low cell supplies less voltage to the coil. That is normal behaviour for low-power devices without heavy regulation, and plugging in for a short top-up is usually enough to restore the original feel.

Disposing of the device: a built-in lithium-ion battery should never go in the household bin or the kerbside recycling, because crushed cells can start fires in collection vehicles and waste facilities. In the UK, vapes are treated as waste electrical equipment (WEEE). Retailers that sell vaping products are expected to offer take-back for old devices, and you can also drop them at your local council recycling centre or at in-store small electrical recycling points in many supermarkets and DIY stores. The Recycle Your Electricals site lets you search by postcode for your nearest drop-off point. Empty the tank and coil of e-liquid where you can, and keep the device away from other waste until you drop it off.

Prism T18E coil technology and tank design

The coil is the part that actually makes the vapour, and in the Endura T18E it is the replaceable Prism T18E 1.5 ohm coil. This is a conventional coil: a length of resistance wire wrapped around a wick of cotton, sitting inside a metal housing that has small holes through which e-liquid is drawn from the tank. It is not a mesh coil. That distinction is worth understanding because mesh coils, found in many newer pod kits and disposables, spread heat across a wide flat surface and tend to produce a bigger initial flavour hit; a round-wire coil like this one heats a smaller area, which is exactly what a low-power MTL device wants.

Key points about the coil:

• Resistance: 1.5 ohm, which suits low-power MTL vaping and keeps battery drain modest
• Wicking: cotton, which handles balanced PG/VG liquids and most nicotine salts well
• Replacement: the coil is a consumable that you buy separately and swap when it wears out
• Compatibility: buy coils listed specifically for the Endura T18E, because older or different Prism coil types from other Innokin lines are not guaranteed to fit or to perform the same way

How long a coil lasts depends on your habits and your e-liquid. As a rough guide, many vapers get somewhere between one and three weeks from a coil. Lighter users and users of simple, low-sweetener liquids sit at the longer end, while heavy daily users and users of sweet, dessert-style liquids tend to need a fresh coil sooner.

Signs the coil is on its way out:

• A burnt or toasted taste that does not clear after a refill
• Flavour that has gone flat or faint even with a fresh tank
• Spitting, gurgling or a dry feel even when the tank is clearly full
• A darkened, sticky appearance when you look at the coil head

To change the coil, empty the tank if you can, separate the tank from the battery section, unscrew the old coil, screw in the new one hand-tight, refill and then let the new coil soak for five to ten minutes before use. Do not overtighten, because the threads and seals are small and need only gentle pressure.

One habit does more than anything else to extend coil life: never fire the device when the tank is empty. A coil with no liquid reaching it burns the cotton within a few puffs, and no amount of priming will rescue it. Refill when the liquid level is low rather than waiting until the first dry hit.

Nicotine strength guidance for the Endura T18E

Choosing a nicotine strength is the single biggest factor in whether a new vape feels right or wrong, and it is more important than which device you buy. Some basic UK rules frame the choice. Nicotine e-liquids in the UK are capped at 20mg/ml (2 per cent), tanks are capped at 2ml, and refill bottles are capped at 10ml. The 20mg limit is a legal ceiling that applies across the market, including to the liquid sealed inside pods and any disposable products, so you will not find higher strengths on legitimate UK shelves.

The Endura T18E's 1.5 ohm, low-power MTL setup works with both main types of nicotine. Here is a rough starting guide. It is general information, not medical advice:

• Nicotine salt, 20mg/ml: a common starting point for people who smoke around 15 or more cigarettes a day and want a strong, quick satisfaction
• Nicotine salt, 10mg/ml: suits lighter smokers, or anyone who finds 20mg too sharp or too strong
• Freebase, 12mg/ml: a more traditional strength for moderate smokers who like a noticeable throat hit
• Freebase, 6mg/ml: a good mid-point for people stepping down or those who vape often through the day
• Freebase, 3mg/ml: for people who are well into their reduction, or who are casual users
• 0mg: nicotine-free liquid, useful if you want to keep the habit of vaping while ending your nicotine use

Signs your strength may be too high include a harsh throat hit that makes you cough, a lightheaded or nauseous feeling after a few puffs, a racing pulse, or a rapid headache. Signs it may be too low include persistent cravings, taking many more puffs than expected, or going back to cigarettes between vape sessions. If you feel too low, increase by one step rather than jumping straight to the top of the range.

People who are very new to nicotine, or who do not smoke regularly, should not start vaping. Vaping carries less risk than smoking for people who already smoke, but it is not risk-free, and it is not intended for people who have never smoked. If you want to quit nicotine completely, the NHS stop-smoking services offer free support in the UK, and a pharmacist or GP can advise on combining vaping with other aids.

As a practical matter, buy one or two strengths either side of your best guess when you place your first order of e-liquid. Because bottles are small and inexpensive, it costs very little to find the strength that suits you, and it is a better outcome than tolerating a harsh or unsatisfying setup for weeks.

Who the Endura T18E is for, and who should look elsewhere

The T18E suits a specific, fairly large group of people, and being clear about who they are is more useful than claiming it fits everyone.

Who it suits well:

• Adult smokers making a first switch: the pen shape, the snug draw and the inhale-to-vape operation closely match the habits of smoking
• People moving on from disposables: since single-use vapes were banned from sale in Great Britain from 1 June 2025, many former disposable users are looking for a refillable replacement that is similarly simple
• Anyone who wants a no-fuss device: no wattage to dial in, no menus to learn and no app to download
• Light to moderate vapers: the battery and tank sizes are matched to typical daily consumption
• People who want a backup or travel device: its slim size makes it easy to carry alongside a main kit
• Budget-conscious buyers: a refillable kit with inexpensive consumables costs less to run over time than a stream of single-use products

Who should look elsewhere:

• Cloud chasers and direct-to-lung (DTL) vapers: a 1.5 ohm MTL coil at low power will feel restrictive; you need a sub-ohm kit instead
• People who want to tweak settings: there is no adjustable power and no adjustable airflow
• Heavy all-day vapers: a 2ml tank and a 1000mAh cell mean frequent refilling and charging for people who vape constantly, so a larger-battery kit may be more convenient
• Anyone who prefers thick, high-VG juice: the cotton wicking and low power are better suited to balanced PG/VG ratios
• Non-smokers and anyone under 18: vaping products are not for you

One more category is worth naming: people who are on the fence. If you are not sure whether MTL or DTL is right for you, a good rule of thumb is to think about how you smoked. If you drew the smoke into your mouth first and then inhaled, MTL will feel familiar. If you inhale deep and fast straight into the lungs, you may find an MTL device frustrating at first, and it may be worth giving the T18E a fair two-week trial before deciding.

How to use the Endura T18E: first-time setup

Setting the T18E up takes a few minutes and involves no technical steps. Follow this routine for your first fill, and it will become second nature.

• Step 1, check the parts: unpack the device, tank, coil and cable, and confirm that a Prism T18E coil is fitted. Keep the manual for reference
• Step 2, charge fully: plug the device into a USB power source and charge until the indicator shows it is complete, which usually takes a couple of hours
• Step 3, open the fill port: follow the opening instructions in the manual to expose the top-fill port. Tilt the tank slightly and aim the bottle nozzle at the side wall, not directly onto the central airflow tube
• Step 4, fill to just below the maximum: do not overfill. Leaving a small air gap helps prevent leaks, particularly when you travel or take a flight
• Step 5, close the port and wait: let the device sit upright for five to ten minutes so the cotton wick fully saturates. Skipping this is the number one cause of burnt first puffs
• Step 6, take gentle first puffs: inhale slowly and steadily for two to four seconds, as you would with an MTL draw. Do not take a hard, long first pull
• Step 7, settle into a routine: top up when the level drops to around a quarter of the tank and charge when the battery runs low

Technique matters more than people expect. MTL vaping works best with a slow, even draw, pulling vapour into your mouth first and then inhaling it, much as you would with a cigarette. Pulling too hard can drag liquid into the airflow path and cause gurgling and spitback. Pulling too lightly may not trigger the draw sensor consistently, so aim for a firm but unhurried breath.

Do not chain vape. Give the coil a few seconds between puffs, since it needs time to re-wick. Constant continuous puffing is a fast route to dry hits and a burnt coil.

If you are storing the device between uses, keep it upright and away from heat. If you are not going to use it for several days, charge it to roughly half and store it somewhere cool, as lithium-ion cells prefer that to being left empty or completely full for long periods.

Finally, always keep e-liquid bottles tightly closed, stored out of reach of children and pets, and away from direct sunlight. Nicotine e-liquid is hazardous if swallowed or spilled on skin, and UK-sold bottles carry child-resistant caps and warnings for that reason.

Troubleshooting common Endura T18E problems

Most problems with pen-style MTL kits come down to a short list of causes. Work through the relevant item before you decide that the device is faulty.

• Burnt or harsh taste: most often an unprimed coil, a tank that has run dry, or a coil at the end of its life. Check the liquid level, prime a fresh coil properly, and replace the coil if the taste does not clear after a refill
• Gurgling, spitting or liquid in the mouthpiece: usually a sign of overfilling, a flooded coil or an overly forceful draw. Empty a little liquid, blow gently through the mouthpiece to clear the airflow channel, and take slower puffs
• Leaking from the base or airflow: check that the coil is seated hand-tight, make sure the tank is not overfilled, and keep the device upright. Leaks after air travel are often caused by pressure changes, so fill slightly below the maximum when you fly
• No vapour, or the device does not fire: confirm the battery has charge, check that the tank and coil are screwed fully into the battery section, and make sure the contacts are clean and dry. A short top-up charge is a good first test
• Weak or flat flavour: a worn coil, an unusually thick liquid, or a flavour that is simply too delicate for the power level. Try a fresh coil or a thinner e-liquid
• Dry hits with a full tank: thick liquid not wicking fast enough, or a coil clogged with sweetener residue. Switch to a balanced PG/VG liquid and fit a new coil
• Battery drains quickly: after a long period of use, built-in batteries lose capacity. If a fresh charge only gives a short period of use and the device was previously fine, the battery may be ageing
• Indicator light flashing: flash patterns vary by device and firmware, so check the manual for the meaning on your unit, as it can signal low battery, a short circuit or a coil connection fault

If you notice a persistent chemical smell, excessive heat from the body of the device, a swollen casing or a split in the battery section, stop using it straight away, do not charge it, and contact the seller or manufacturer. Unusual heat or swelling can indicate a battery fault and should always be treated seriously.

A simple maintenance routine prevents most issues. Every time you change coil, rinse the tank with warm water, dry it fully and wipe the battery contacts with a dry cloth or cotton bud. Avoid soaking the battery section in water, since it contains electronics.

If you have been through these checks and the device still misbehaves, get in touch with our customer support team with your order number, a brief description of what is happening and, where possible, a photo or short video. That gives us what we need to help you quickly, whether that means advice, a replacement coil or a warranty claim.

Value for money and running costs

The value case for a refillable kit like the Endura T18E rests on running costs rather than purchase price. The device itself is a one-off cost. After that, what you spend regularly is e-liquid and coils, and those are where refillable kits pull ahead of other formats.

Here is an illustrative way to think about it. The numbers below are examples, not quotes, so check the live prices on the site before you plan a budget:

• Suppose you use around 2ml of e-liquid a day, which is about one full tank. A 10ml bottle then lasts roughly five days
• If a 10ml bottle costs a few pounds, your weekly liquid spend is a small fraction of the cost of repeatedly buying single-use devices
• If a coil lasts you roughly one to two weeks, you need a handful of coils a month, and coils are usually sold in multipacks that bring the unit price down
• Add a small amount of electricity for charging, which is negligible

Set that beside a daily single-use device, which before the ban often cost more over a month than a complete refillable kit plus its liquid, and which also left a battery and plastic casing in the waste stream every few days. With the sale of single-use vapes now banned in Great Britain, the comparison is mostly academic, but it explains why refillable kits are the sensible default.

It is also useful to compare with smoking. The cost of a pack-a-day cigarette habit in the UK is considerable over a year, and a switch to a refillable kit usually reduces that spending substantially. That is a financial observation, not a health claim, and the health advice for smokers remains that stopping nicotine altogether is the aim, with vaping as a tool some people use to get there.

What you give up for the lower running cost is convenience at the margins. You need to refill, charge and occasionally swap coils, and you need to carry a bottle or keep one at home. For most people that routine quickly becomes automatic. The extra effort is offset by being able to choose exactly the flavour and strength you want, and by not having to throw away a whole device when it runs out of liquid.

Finally, consider the end-of-life cost. The built-in battery means the T18E is not repairable by the user, so when it eventually wears out you will replace the whole device. A device that lasts many months of daily use and then goes to a WEEE recycling point is a reasonable lifecycle for a small, low-cost kit, and a far smaller waste burden than the equivalent number of disposables.

How the Endura T18E compares with similar kits

No device is right for every vaper, so here is a fair comparison with the main alternatives you are likely to be weighing up. The general points below describe categories rather than exact model specifications, which change between versions, so check the listing of any kit you are considering.

Versus pod kits such as the Vaporesso XROS range, the Uwell Caliburn range or the SMOK Novo range. Pod systems are the closest rival. Many have similar 2ml capacities and batteries in a comparable range, and several offer extras the T18E lacks, such as adjustable airflow, power modes or a slightly bigger battery on certain models. Pods are neat and quick to swap, and some people like the convenience of a clip-in cartridge. The T18E counters with a traditional replaceable-coil tank with a long-established coil format, top-fill simplicity and a pen shape that some find more comfortable to hold. If you want a pod style and the extra options, look at the pod ranges. If you prefer the pen feel and minimal operation, the T18E holds its own.

Versus other pen-style MTL kits. The market has a range of pen kits at similar prices, some with larger batteries and some with adjustable airflow. The T18E's positioning is simplicity and Innokin's established coil supply. If long battery life is your top priority, look for kits with 1500mAh or more. If you like to tinker, look for a model with an airflow ring.

Versus larger Innokin Endura models. Innokin makes several devices in the Endura family with different battery sizes and features. The T18E is the straightforward option in that line. If you find you want more battery or more control after using it, moving up within the same brand is a logical next step, and coil compatibility needs checking at that point.

Versus sub-ohm kits. These are a different category altogether. They produce far more vapour, need lower nicotine strengths, use more e-liquid and are aimed at direct-to-lung inhalation. They are unsuitable if you want a cigarette-like draw, and a T18E will not satisfy someone who wants big clouds.

Versus single-use vapes. These can no longer be sold in Great Britain, and in any case they produce more waste, cost more over time and offer no choice of strength beyond the legal 20mg/ml maximum.

An honest summary: the T18E does not win on battery size, features or adjustability. It earns its place through simplicity, a familiar MTL draw, readily available consumables and a manageable price. If those things matter to you more than extras, it is a sensible choice. If you know you want more control or more battery from day one, a different kit from the same price bracket will probably serve you better.
