Innokin Prism T20 Coils: Replacement Coils for the Endura T20
Innokin Prism T20 coils are the 1.5Ω replacement coils for the Innokin Endura T20 kit and its Prism T20 tank, sold in packs of five.
Innokin has stopped making the Endura T20 and no longer has a page for it, so this is a coil for people who already own one. There isn’t much Innokin information left to quote, which is why this page is shorter than most: it sticks to what UK stockists agree on.

What Does the Prism T20 Coil Fit?
The Innokin Endura T20 kit and the Prism T20 tank that comes with it.
The Endura T20 isn’t in our range any more; this pack is for existing owners. Innokin’s current Endura models use T18E or Prism S coils instead.
Will not fit: the Endura T20-S (Prism T20-S tank), EZ.Watt or Apex, which take Innokin Prism S coils, or any Endura T18 or T22 model (T18E coils or the original T18 coil).
How to Change a Prism T20 Coil
- Unscrew the base of the tank.
- Pull the old coil out of the base and plug the new one in.
- Wet the cotton with a few drops, refit and wait five minutes.
How Long Does a Prism T20 Coil Last?
No official figure exists. Keep the tank topped up and avoid very sweet liquids to get the most from each coil.
