Innokin Prism S T20S Coils

Two resistances, both Kanthal dual coils, both low-wattage. The 0.8 ohm runs at 16 to 18W for a warmer draw with a touch more vapour.

The 1.5 ohm runs at 13 to 14W for a tighter, cooler, cigarette-close MTL pull. Both use organic Japanese cotton and sit vertically in the tank base with auxiliary wicking ports that keep the cotton fed evenly.

They fit the Endura T20S, EZ.WATT and Endura Apex, but not the older T20. Sold in packs of 5. Pirate Vapes ships them age-verified across the UK.

Why vapers choose this:

• Kanthal dual coil heats from two wires for fuller, warmer flavour.

• Organic Japanese cotton wicks cleanly and handles repeated heating well.

• Two resistances covering a warmer RDL draw and a tight MTL pull.

• Auxiliary wicking ports keep the cotton fed and reduce dry hits.

• Five to a pack, lasting a month or more at these low wattages.

Innokin Prism S T20S Coils Features

Dual Coil, Not Single

Both the 0.8Ω and 1.5Ω run two Kanthal wires inside the housing rather than one. That dual setup heats your e-liquid from two contact points, which spreads the temperature more evenly and produces a denser, more flavourful draw than a single wire would at the same wattage. At 13 to 18W, the difference is subtle but noticeable.

0.8Ω for Warmth, 1.5Ω for Tightness

The 0.8 ohm is the one for a slightly warmer, looser draw. A bit more vapour, a bit more throat feel, closer to a restricted lung hit than a pure MTL. The 1.5 ohm tightens everything up: cooler vapour, less cloud, a draw that sits right next to a cigarette. Both handle Nic Salts and 50-50 E-Liquid well.

Japanese Cotton, Clean Taste

The wicking is 100% organic Japanese cotton, which is a material that absorbs quickly, holds e-liquid evenly, and does not add any taste of its own. It handles heat cleanly, so the flavour you get is the flavour of your juice rather than the coil. At the low wattages these coils run, the cotton lasts well before it needs replacing.

Vertical Design With Extra Ports

The coil sits vertically in the tank base, and Innokin added auxiliary wicking ports around the barrel. Those extra openings let e-liquid reach the cotton from more angles, which reduces the chance of a dry spot forming on one side. Fewer dry hits, longer coil life, and consistent flavour through the tank.

T20S Only, Not the Older T20

This is the most common mistake people make when ordering. The Prism S coils fit the T20S tank, the EZ.WATT and the Endura Apex. They do not fit the older Endura T20. The coils look similar, but the fitment is different. Check the name on your tank before ordering.

Innokin Prism S T20S Coils Resistance Options

Fill the tank with your own juice. Two options.

• 0.8 ohm - Kanthal dual coil, 16 to 18W, a warmer draw with more vapour, suits 50-50 E-Liquid

• 1.5 ohm - Kanthal dual coil, 13 to 14W, tighter MTL, cooler, best on Nic Salts

Both suit thinner juice. Avoid thick high-VG in either. Browse our E-Liquids collection for the right match.

How to Set Up the Innokin Prism S T20S Coils

1. Unscrew the base of your T20S tank and remove the old coil.

2. Fit the new Prism S coil into the base and tighten by hand.

3. Work a drop or two of juice into the cotton visible on the outside of the coil.

4. Reassemble the tank, fill with e-liquid, and let it sit for three to five minutes before the first draw.

What's in the Innokin Prism S T20S Coils Box

Five Prism S coils in the resistance you choose. No tank, no device, no e-liquid. Grab a bottle of Nic Salts or 50-50 E-Liquid to fill your tank.

Built for the Endura T20S, EZ.WATT and Apex

Innokin Prism S coils are made specifically for the T20S platform and fit devices including the Innokin Endura T20S Kit, Prism T20S Tank, EZ.WATT Kit, and Endura Apex. They do not fit the older Endura T20, as it uses a different coil type. Always check that your tank says T20S before ordering.

You will find the coils and the kits in our Innokin Vapes collection, with the full coil range in Vape Coils.

About Innokin

The Endura T20S is one of those kits that quietly sells by the thousands. No headlines, no influencer campaigns, just a pen that smokers buy when they want something that feels familiar and works the first time.

The Prism S coil is the engine behind it: a dual-wire Kanthal build with Japanese cotton that runs at low power and produces clean, consistent flavour for a week or two per coil. Innokin made its name on this kind of reliability, and the T20S line carries it forward without needing to shout about it.

Stock Up and Save

Five coils at these wattages last a long time. A single pack covers six weeks or more if you vape moderately, and pairing it with a couple of bottles from our Multibuys page keeps the total running cost low.

Genuine Innokin, dispatched tracked, age-verified checkout. Over 18s only. If you are ordering for the first time, grab one pack of each resistance to find which draw you prefer.

Conclusion

Two coils, one tank, and a line that has been quietly doing its job for years. The 0.8Ω for warmth and the 1.5Ω for tightness. Both Kanthal dual coils, both Japanese cotton, both running at low enough wattage that batteries and juice stretch well.

Just make sure you are ordering for the T20S, not the older T20. Grab a 5-pack from Pirate Vapes with fast, age-verified UK delivery.

FAQs

Will these fit my T20?

Only if it is the T20S (with the S). The older T20 uses a different coil with a different fitment. Check the name printed on your tank.

0.8 or 1.5, which one?

The 1.5Ω is tighter and cooler, closest to a cigarette. The 0.8Ω is warmer with a bit more vapour. Both are MTL at heart. Try the 1.5Ω first if you are new to vaping.

What juice should I use?

Nic Salts or 50-50 E-Liquid. Both resistances are designed for thinner, higher-PG juice. Thick high-VG will not wick properly in these coils.

How long does a coil last?

One to two weeks of regular use. At 13 to 18W, the coils do not work hard, so they outlast most higher-power options. Lighter juices stretch the life further.

Are these the same as Z-Coils?

No. Prism S coils fit the T20S, EZ.WATT and Apex only. Z-Coils fit the Zenith, Zlide and Kroma-Z platforms. They are completely different coils for different tanks.

Is there a mesh option?

A 0.9Ω Prism S mesh coil exists but is not always stocked. The two main options are the 0.8Ω and 1.5Ω dual coils listed here.
