Description
Innokin Prism S Coils for the Endura T20-S, EZ.Watt and Apex
Innokin Prism S coils are the replacement heads for Innokin’s Prism-S tank, the MTL tank on the Endura T20-S, sold five to a pack. We list the 0.8Ω and the 1.5Ω.
Innokin calls Prism-S its next-generation Prism system, and it’s a separate coil from the T18, T18E and T20 – the table further down shows which Prism coil goes where, because the names are easy to mix up.

Prism S Coil Resistances and Wattage
Innokin prints 16–18W on the 0.8Ω coil; UK stockists give 13–14W for the 1.5Ω. Innokin also makes a 0.9Ω mesh version, which we don’t list.
| Resistance | Wattage | Draw | Notes |
|---|---|---|---|
| 0.8Ω | 16–18W | MTL | Suits the T20-S at full power |
| 1.5Ω | 13–14W | MTL | Not for the Endura Apex |
Which Kits Take Innokin Prism S Coils?
Innokin’s Endura T20-S uses the Prism-S tank and coil. UK stockists also list the EZ.Watt and the Endura Apex, and the Prism T20-S and Apex tanks sold on their own.
We don’t currently stock the Endura T20-S, EZ.Watt or Apex, so these are for existing owners. Innokin gives the T20-S a top-fill 2ml tank, an 18W maximum output and a minimum atomiser resistance of 0.6Ω, which is why the 0.8Ω suits it so well.
Will not fit: the Endura T18 2, T18E or original T18/T22 (T18E coils or Prism T18 coils), or the original Prism T20 (Prism T20 coils). The 0.8Ω is also below the Endura T18 2’s 1.2–3.9Ω range.
How to Fit and Prime a Prism S Coil
- Remove the tank from the battery and unscrew its base.
- Take out the old coil and fit the new one.
- Add a few drops of e-liquid to the wick openings.
- Reassemble, fill from the top and wait five minutes.
How Long Does a Prism S Coil Last?
Innokin doesn’t publish a figure. At 16–18W a 0.8Ω coil works a little harder than the 1.5Ω, so the 1.5 usually lasts longer. Keep the tank topped up and change the coil when the flavour fades.
Prism S Coil Troubleshooting
| Problem | Likely cause and fix |
|---|---|
| 1.5Ω won’t fire in my Apex | The Apex takes the 0.8 and 0.9 only. |
| Burnt taste | Prime the wick and wait five minutes before firing. |
| Leaking | Check the base O-ring and that the coil is fully seated. |
Which Innokin Prism Coil Do I Need?
| Coil | Kits and tanks | Resistances |
|---|---|---|
| Prism S (this page) | Endura T20-S, EZ.Watt, Apex | 0.8, 1.5 (and 0.9 mesh) |
| Prism T18E | Endura T18 2, T18E, T22E, T18 X | 1.5 (and 1.7) |
| Prism T18 | Original Endura T18 and T22 | 1.5 |
| Prism T20 | Endura T20 | 1.5 |
Best E-Liquids for Prism S Coils
UK stockists recommend 50/50 or high-PG liquid. On the 0.8Ω, 10mg or 20mg nic salts or 50/50 freebase e-liquids work well.
