Innokin Prism S T20S Replacement Coils Pack Of 5

Innokin Prism S T20S Replacement Coils Pack Of 5

This pack contains 5 genuine Innokin replacement coils built for the T20S tank, the atomiser fitted to the Innokin Prism S kit. If your Prism S has started tasting burnt, flat, or gurgly, the coil is almost always the cause, not the e-liquid and not the device itself. Keeping a few spares of the Innokin Prism S T20S Replacement Coils Pack Of 5 in a drawer means you're never caught out mid-week with a dying coil and no way to fix it.

What The T20S Coil Is Designed For

The T20S coil is the atomiser head built specifically for the T20S tank that comes with the Innokin Prism S all-in-one kit. It is not a universal coil, it is sized and threaded to fit that tank, so it will not drop straight into a different Innokin tank family or a different brand's device. If you're unsure which tank your Prism S uses, check the coil that's currently fitted: the packaging or the coil body itself will usually be marked "T20S". When buying replacements, matching the coil to the tank model is more important than matching it to the device name, since Innokin has used the T20S tank across more than one kit generation.

Buying Innokin Prism S T20S Replacement Coils Pack Of 5 in the UK gets you a proper multipack rather than a single coil, which works out better value if you vape daily, coils are consumable parts, not one-off purchases.

Coil Resistance and Vaping Style

Innokin typically offers T20S coils across a small range of resistances to suit different vaping preferences, generally split between:

• Lower resistance coils, built for a more direct, airy draw with denser vapour, usually paired with higher-VG e-liquids at lower nicotine strengths (freebase nicotine rather than nic salts).
• Higher resistance coils, built for a tighter, cigarette-like draw (mouth-to-lung), which suits nic salt e-liquids and higher nicotine strengths, and tends to be gentler on throat and battery.

If you're replacing a coil that's already fitted to your Prism S, the simplest approach is to buy the same resistance again unless you're deliberately trying to change how the device feels to vape. Switching resistance changes airflow, vapour production, and how quickly you go through e-liquid, so it's worth doing on purpose rather than by accident.

When to Replace Your T20S Coil

Coils are a wear part. The wicking material inside gradually saturates with residue from e-liquid and burnt cotton, and the wire itself loses its even heating over time. No coil lasts forever, regardless of brand or price. Common signs it's time to swap in a fresh one from your pack include:

• A burnt or "dry hit" taste, even straight after refilling the tank
• Flavour that's gone noticeably flat, muted, or metallic compared to when the coil was new
• Gurgling, crackling, or spitting sounds during a draw
• Visible discolouration or a build-up of gunk on the coil head
• Reduced vapour production despite the battery and e-liquid both being fine
• Leaking from the base of the tank around the coil

How Long Does a Coil Actually Last?

There's no fixed answer, it depends on how much you vape, what e-liquid you use, and how you look after the coil. As a rough guide, most vapers find they get somewhere between one and three weeks of daily use from a single coil before flavour starts to noticeably drop off. Sweeter or higher-VG e-liquids tend to gunk up coils faster than simpler formulations. Having a pack of 5 on hand means you're not rationing a coil well past its best just because you don't have a replacement.

How to Fit and Prime a New T20S Coil

Fitting a new coil correctly matters more than most people realise, a coil that isn't primed properly will give you a dry, burnt hit on the very first draw, which can make a perfectly good coil seem faulty when it isn't. Take a few minutes and do it properly:

• Empty and disassemble the tank. Unscrew the tank from the Prism S battery and tip out any remaining e-liquid before opening it up.
• Remove the old coil by unscrewing it from the base of the tank, and dispose of it responsibly, don't just bin it loose, as coils contain a small amount of metal and cotton.
• Screw in the new coil from your pack, hand-tight only. Don't overtighten, the seal comes from the O-rings, not brute force.
• Prime the coil before using it. Drip a few drops of e-liquid directly onto the visible wicking holes or exposed cotton on the coil, and let it sit for 3, 5 minutes so the cotton fully soaks through.
• Refill the tank as normal, then let the full tank sit for another few minutes before vaping, this gives e-liquid time to travel down into the coil through capillary action rather than you having to draw it through by vaping.
• Start on a lower power setting if your Prism S allows adjustment, and take a few slow, gentle draws before vaping normally. This lets the cotton toughen up gradually rather than scorching on the first big hit.

Skipping the priming step is the single most common reason a brand-new coil tastes burnt straight out of the pack, it's very rarely a faulty coil, almost always a dry one.

Getting the Best Flavour and Longest Coil Life

A few habits make a genuine difference to how long each coil in your Innokin Prism S T20S Replacement Coils Pack Of 5 lasts, and how good it tastes while it does:

• Don't let the tank run dry. Vaping on an empty or near-empty tank is the fastest way to scorch a coil that would otherwise have plenty of life left in it.
• Take slower, gentler draws rather than rapid back-to-back puffs, which don't give the wick time to resaturate between draws.
• Match your e-liquid to the coil's resistance. Thicker, high-VG liquids can struggle to wick properly through higher-resistance coils built for thinner nic salt liquids, and vice versa.
• Rinse and dry a coil if it's temporarily flavour-tainted from switching e-liquid flavours, rather than assuming it needs replacing, though this only buys limited extra life, not a full reset.
• Store spare coils somewhere dry and out of direct sunlight until you need them, so the packaging and cotton stay in good condition.

UK Compliance and Nicotine Information

These are replacement coils, not e-liquid, they don't contain nicotine themselves, but they're intended for use with vaping devices that typically do. Under UK TPD regulations, nicotine-containing e-liquids sold in the UK are capped at 20mg/ml (2%) for nic salts and freebase alike, and vaping products are for adults 18+ only. If you're using 0mg e-liquid in your Prism S, it contains no nicotine at all, but the coil itself works the same way regardless of nicotine strength, since its job is heating and vapourising liquid, not the nicotine content of that liquid.

FAQ

Will these coils fit any Innokin device?

No. They're built specifically for the T20S tank used on the Innokin Prism S kit. Always check the tank model fitted to your device rather than assuming by kit name alone, since tank compatibility can carry across or differ between Innokin kit generations.

Why does my new coil taste burnt already?

This is almost always down to priming, not a faulty coil. Make sure you've dripped e-liquid onto the coil's wicking holes and left it to soak for a few minutes, then filled the tank and waited again before vaping, as described above.

How many coils will I get through in a pack of 5?

That depends entirely on your vaping habits, but as a guide, five coils at roughly one to three weeks each could realistically cover a couple of months of daily vaping, which is why buying a pack rather than a single coil tends to work out more convenient and better value.

Can I clean a coil to make it last longer instead of replacing it?

You can rinse a coil in cooled boiled water and let it fully dry out to squeeze a bit more life out of it, particularly if it's just flavour-tainted rather than genuinely burnt. It's a short-term fix rather than a substitute for replacement, though, a worn coil won't perform like a fresh one no matter how well it's cleaned.

Do I need to change my e-liquid when I change resistance?

Not necessarily, but it's worth thinking about. Lower-resistance coils generally suit higher-VG, lower-nicotine freebase liquids, while higher-resistance coils tend to suit nic salt liquids at higher strengths, up to the UK's 20mg/ml cap. Mismatching the two won't damage anything, but you may find wicking or flavour isn't as good as it could be.
