Innokin Prism S T20S Replacement Coils Pack Of 5: What You Are Ordering

Innokin Prism S T20S Replacement Coils Pack Of 5 is a five coil pack costing £9.95, supplying the heating elements for the Prism S tank fitted to Innokin's T20S hardware. The name is doing two jobs at once, which confuses people, so it is worth unpicking straight away: Prism S is the coil family, and T20S is the device that tank belongs to. Buy the pack that names both and you are in the right place.

Innokin occupies a slightly unusual position in vaping. While much of the industry chases larger clouds and bigger numbers, Innokin has spent years building equipment aimed at a tight, restricted draw that behaves rather like a cigarette. That focus has made the brand a fixture in the starter market, and it is why so many people whose first vape was an Innokin are still buying the same coils years later.

We stock four products across the Innokin range, and this pack sits alongside the rest of our replacement coils, which are grouped by fitting so you can find the correct part without memorising manufacturer model codes.

Vaping products are sold to adults only. You must be aged 18 or over and every order placed with us is verified before dispatch.

Why Mouth to Lung Coils Are Built Differently

The style of vaping this coil is designed for has a name, and understanding it explains almost every design decision in the part you are holding.

Mouth to lung means you draw vapour into your mouth first, hold it briefly, then inhale it. It is the way people smoke, which is precisely why it is the style most adults find natural when they first move across from cigarettes. The alternative, direct to lung, means pulling vapour straight into the chest in one motion, which feels completely alien to anyone who has never done it and produces far more vapour than most newcomers want.

Coils built for a mouth to lung draw share a set of characteristics that follow logically from that purpose.

They run at higher resistance. More resistance means less current for a given voltage, which means less heat, less vapour and a draw that stays comfortable in the mouth rather than filling the room.

They use less power. These coils are designed for modest wattage, which is why devices in this class have small batteries and still last a full day.

They consume liquid slowly. Less vapour per puff means a tank lasts far longer than it would in a high output setup, and it also means a coil survives longer because it is being worked less hard.

They pair with a restricted airflow. The tight draw is not a limitation, it is the entire point. It concentrates flavour and produces the throat sensation people switching from smoking are generally looking for.

Buy this coil expecting enormous clouds and you will be disappointed. Buy it wanting a discreet, cigarette like draw that lasts all day on one charge and it does exactly what it was designed for.

The Liquid That Belongs in It

Choosing liquid for a mouth to lung tank is a different exercise from choosing it for a big sub ohm setup, and getting it wrong produces problems people usually blame on the coil.

The critical property is thickness. Vegetable glycerine is a thick, syrupy liquid and propylene glycol is thin and watery. High VG liquids, the sort sold in large shortfill bottles for cloud production, do not travel easily through the narrow wicking channels a mouth to lung coil uses. The wick struggles to keep up, and the result is a dry, harsh puff that tastes burnt even though the coil is brand new and correctly fitted.

What suits these coils is a balanced liquid, the sort usually described as 50/50, where the thinner component keeps everything moving properly. That description covers the overwhelming majority of 10ml bottles sold in the UK, which is convenient, because those are also the bottles that carry nicotine at usable strengths.

On strength, the higher resistance and low vapour output mean these coils suit stronger liquid than a sub ohm device would. Adults who have recently switched from smoking commonly use the higher end of what UK law permits, which is 20mg per millilitre, and salt based formulations make that strength comfortable rather than harsh. Our nicotine salt e-liquid range covers the bottles built for exactly this kind of hardware.

Sweetened liquids work perfectly well here too, with the usual caveat that they shorten coil life. Because mouth to lung coils are worked so much more gently than sub ohm ones, though, even a sugary blend tends to last longer in this tank than it would in a high power setup.

Changing the Coil So the Tank Stays Dry

Changing a coil in a tank is a slightly more involved job than swapping a pod, and three specific mistakes account for nearly every leak that follows a coil change.

Empty the tank first. Trying to change a coil in a full tank is how liquid ends up across the kitchen worktop and inside the battery. Vape it down or decant what is left back into a bottle.

Do not overtighten. This is the big one. A coil should be screwed in until it seats and then stopped. Cranking it hard compresses the sealing rings past their designed shape, and a squashed ring seals worse than a relaxed one rather than better. Firm and snug beats tight every time, and it also means you can remove it again without pliers.

Check the sealing rings. Every threaded joint in a tank has a small rubber ring doing the actual sealing. If one has rolled out of its groove, split or gone missing during a previous change, the tank will leak no matter how carefully the coil is fitted. Look before you assemble.

Once the coil is in, wet the wicking slots with a few drops of liquid, fill the tank, and then leave it standing for ten minutes or so before using it. That pause is what allows the cotton to saturate fully. Firing a dry wick scorches it permanently and there is no way back from that, which is why the pack contains five coils and why it is worth not wasting the first one through impatience.

Getting a Long Life Out of Each One

The good news for anyone running this style of tank is that coil life is generally far better than it is in higher powered equipment, simply because the coil is doing less work. A few habits extend it further.

• Keep the tank topped up. Vaping down to the last few millilitres repeatedly is the fastest way to stress a wick. Refilling when the tank is around a third full costs nothing and adds days.
• Leave a moment between puffs. Continuous chain vaping outruns the wick's ability to resaturate, even at modest power. A few seconds is enough.
• Stay within the printed power range. Every coil carries its resistance and recommended wattage on the body. The lower end of that range gives cleaner flavour and a longer life.
• Stick to one flavour per coil where you can. Cotton holds onto whatever it has soaked up, so switching from a dessert to a light fruit mid coil gives you a muddled version of both.
• Change on flavour rather than schedule. When definition starts slipping and the liquid tastes flatter than it did, that is the moment. Waiting for an outright burnt taste means several days of poor vaping first.

Five coils used this way represent a long stretch of ordinary use for most people in this style, which is a substantial part of why mouth to lung setups are cheaper to run than they first appear. If you are shopping for the hardware itself, our starter vape kits section is where this class of device lives.

The Other Innokin Consumables We Carry

Innokin has produced a long line of devices over the years and the consumables are not interchangeable between them, so it is worth knowing which of our four listings applies to what you own.

Innokin Zenith Z Coils Pack of 5 at £8.95 serve the Zenith line of tanks, which is Innokin's long running mouth to lung platform and one of the most widely used in the UK. At £1.79 per coil they are the keenest priced pack we hold from the brand.

Innokin Jem Coils Pack Of 5 at £11.95 fit the Jem hardware, working out at £2.39 apiece. Different platform, different fitting, and not compatible with the Prism S tank.

Innokin VCAP Replacement Pods at £5.95 are a different kind of consumable altogether. Those are complete pods rather than coils, for devices where the heating element is built into the pod body and the whole assembly is replaced when it is spent.

If you are unsure which family your device belongs to, the coil currently fitted is the most reliable evidence, since Innokin prints the family name on the coil body. The box the kit came in is the next best source. Ordering by guesswork is how people end up with a drawer of coils that fit nothing they own.

Diagnosing the Common Complaints

Everything tastes faintly burnt but the coil is new. The liquid is probably too thick for the wicking channels. Move to a balanced 10ml bottle rather than a high VG shortfill and the problem usually disappears entirely.

The tank leaks after a coil change. Almost always overtightening or a sealing ring out of position. Take it apart, check every ring is seated in its groove, reassemble snugly rather than forcefully.

The draw has become tight or blocked. Check the airflow ring is open and not clogged. Pocket lint gets into the airflow of every device eventually and it restricts a mouth to lung draw far more noticeably than an open one.

Flavour is fine but there is barely any vapour. That may simply be the style working as intended, since mouth to lung setups produce modest vapour by design. If it has genuinely dropped compared with last week, the coil is ageing.

Liquid disappears far faster than usual. Look for a leak into the airflow rather than assuming you have been vaping more. A coil not fully seated will drain a tank quietly while you are not watching.

Most tank problems are mechanical rather than electrical, and the fix is nearly always found by taking the tank apart and looking at it properly rather than by replacing the device.

Buying From Us and What Happens Next

We source through authorised UK distribution and hold stock ourselves, which matters more with consumables than with almost anything else, since counterfeit coils are common and perform poorly enough to make people think their device has failed.

Orders placed and paid for before 4pm on a working day are packed and go out with that afternoon's collection. Anything later, along with weekend and bank holiday orders, is dispatched on the following working day. UK delivery costs nothing once your basket total goes past £20, and a coil pack at £9.95 alongside a couple of bottles of liquid reaches that comfortably. Below the threshold a standard postage charge applies and is shown at checkout before payment is taken.

Age verification is carried out on every order. This is an 18+ purchase, identification may be requested before we dispatch, and the requirement applies to coils and hardware exactly as it does to nicotine containing liquid.

Looking after it, and what goes wrong

The faults people blame on a product are usually storage or priming.

• Prime before the first draw. Click the pod in and leave it a minute. Drawing on a dry wick is what causes that scorched first hit.
• Keep it cool and upright. Heat thins liquid and pushes it through seals, which is why a hot car is the usual cause of a leak.
• Muted flavour is often you, not it. Palate fatigue is common on a single flavour, and rotating to a second profile resets it.
• Store away from children and pets, and recycle spent hardware rather than binning it loose.

None of that is demanding, and it is the difference between a product that performs to the end and one that disappoints halfway.

Buying this as a first purchase

First time buying this sort of product? The decisions that matter are simpler than the shelf suggests.

1. Format. A prefilled pod is the no-mess option. Bottled e-liquid costs less per millilitre if you do not mind refilling.
2. Strength. This comes in 0mg. Heavier former smokers usually start high and step down.
3. Flavour. Pick two from different families rather than committing to one.

Everything else is preference rather than a decision that costs you money. The deals page is the cheapest way to try more than one at a time.

Delivery, returns and buying with confidence

Ordering is deliberately simple. Weekday orders placed before 4pm are dispatched the same day, and UK delivery is free once your basket reaches £20.00. Tracked options are shown at checkout.

Opened consumables are not returnable, which is standard for the category. If something arrives faulty or incorrect, contact us and we will sort it. Age verification applies to every order, and unverified orders are refunded rather than sent.

Nicotine is addictive. These products are for adult smokers and vapers.

Common problems and how to avoid them

Most support questions we get come down to four things.

A burnt taste on a new device. Almost always a pod drawn on too soon. Click it in and leave it a minute before the first pull. A scorched wick cannot be rescued, so the minute is worth it.

Leaking. Usually heat or pressure. Warmth thins liquid and pushes it through seals, so a hot car or a sunny windowsill is the usual culprit. Cabin pressure on a flight does the same thing, which is why storing spares upright in a bag beats loose in a pocket.

Flavour fading. Frequently the palate rather than the product. If a flavour dulls after a week, switching to a contrasting profile for a day or two usually brings it back sharply.

Buying the wrong fitment. Pods are not universal, and even within one brand the families differ. Check the listing names your device before ordering rather than after. Spares and accessories are grouped separately if you need a replacement part.

What changed when disposables were banned

The shelf you are shopping from looks nothing like it did two years ago. Single-use disposable vapes were banned in the UK, and the market replaced them with rechargeable devices that take replaceable pods. The experience is deliberately similar: prefilled, no measuring, no mess. The difference is that the battery survives the flavour, so you replace a pod for a couple of pounds rather than the whole unit.

The economics moved in the customer\u2019s favour. A device bought once and fed with pods costs less over a month than a stream of sealed units, and produces far less waste. It also changed how you shop: the decision splits into hardware first, then consumables, rather than being one purchase repeated endlessly.

We only sell compliant, UK-distributed stock. That means 2ml pods, 10ml nicotine bottles and a 20mg strength ceiling, with age verification on every order. Rechargeable kits and replacement pods are the two halves of that system if you are still assembling yours.
