Description
The Innokin Prism S is the coil that keeps the Endura T20-S, EZ Watt and Apex running properly, and it’s a regular reorder for a lot of our customers here at Pure E-Liquids. If your flavour has started to fade or you’re getting the odd gurgle from your tank, a fresh coil is usually the fix, and buying five at a time saves you coming back to us every fortnight.
Three resistances are available in this pack, each suited to a slightly different vaping style. The 1.5 ohm gives the tightest, most restricted draw and is the closest thing to a cigarette-style pull. The 0.8 ohm opens things up a little for warmer vapour and fuller flavour. The 0.9 ohm uses a mesh coil rather than traditional wound wire, which tends to bring out more flavour from your e-liquid thanks to faster, more even heating.

Dimensions and Weight
Each individual coil is approximately 3.3cm tall (1.3 inches) and 1.3cm in diameter (0.5 inches). A box of 5 coils weighs around 11g in total, which is 0.011kg, or approximately 0.024lbs. Dimensions and weight are the same across all three resistances.

Coils only, no tank, drip tip or device included
Coil and Compatibility Guide
The Prism S coil is a direct fit for Innokin’s own T20 Prism tank, which is what comes fitted to the Endura T20-S and EZ Watt kits, as well as the Innokin Apex kit and its dedicated Apex tank. If you’re running an Apex, note that the 1.5 ohm variant isn’t compatible with that particular tank, so stick to the 0.8 ohm or 0.9 ohm mesh for that device.
Swapping a coil is straightforward. Unscrew the base of the tank (ideally with a little e-liquid still in there to avoid drips), remove the spent coil, and press the replacement into place with the 510 pin down. Screw the base back on, top up the tank, and give it 5 to 10 minutes before vaping so the cotton fully soaks through. Skipping this step is the number one reason a brand new coil tastes burnt within seconds.
Recommended E-Liquids
This coil is built for high PG and 50/50 juice rather than sub-ohm shortfills, so it’s a good match for our nic salt e-liquid range, which is formulated with MTL devices exactly like this in mind. If you’d rather stick with freebase nicotine, our wider Innokin coils selection will give you an idea of the resistance ranges and juice pairings that work well with restricted-draw tanks like this one.
Usage and Maintenance Advice
Always prime a new coil before use. A couple of drops of e-liquid directly onto the exposed cotton, followed by filling the tank and leaving it to stand, gives the wick time to saturate properly. Never fire the coil dry, even briefly, since this can scorch the cotton on the first puff and ruin the coil before you’ve had a chance to use it. Depending on usage and juice choice, most vapers get somewhere between 3 and 10 days from each coil. Sweeter e-liquids tend to gunk the wicking faster and shorten that lifespan.
