Innokin Jem Pen Coils — Fresh Coils, Fresh Flavour
The Innokin Jem Pen Coil is a replacement coil designed for the Innokin JEM vape pen that restores your device to full flavour and vapour production. Available in 1.6 Ohm and 2.0 Ohm resistance options, these coils slot straight into your JEM pen and get you back to clean, satisfying draws within seconds. If your vape has started tasting a bit burnt or the vapour output has dropped off, a fresh coil is almost always the fix.
Which Resistance Should You Pick?
The two ohm ratings change how the JEM pen feels in your mouth and how much vapour you get. Here is the practical difference:
| Resistance | Draw Style | Vapour | Flavour | Battery Life |
|---|---|---|---|---|
| 1.6 Ohm | Mouth-to-lung, slightly looser | More vapour | Warmer, fuller | Slightly shorter |
| 2.0 Ohm | Mouth-to-lung, tighter | Less vapour | Cooler, crisper | Longer lasting |
If you want a draw that feels closer to a cigarette, go with the 2.0 Ohm. If you prefer a bit more warmth and cloud, the 1.6 Ohm is the one. We'd pick the 1.6 Ohm for fruit and dessert e-liquids and the 2.0 Ohm for tobacco and menthol — the tighter draw suits those profiles better.

These are the specs you need to confirm compatibility with your device. The Innokin JEM coils only fit the JEM pen — they will not work with other Innokin devices like the Endura T18 or T20.

Complete your setup: if your JEM pen's tank is looking scratched or the seals are wearing out, grab a full Innokin JEM Pen Kit to start fresh. Pair these coils with a quality mouth-to-lung e-liquid for the best results — thinner, higher-PG juices work noticeably better with the JEM's coil design than thick, high-VG blends.
Why You Need Fresh Innokin Jem Pen Coils
A coil is the part of your vape pen that heats the e-liquid and turns it into vapour. Over time — typically every 1 to 3 weeks depending on how heavily you vape — the cotton wick inside the coil degrades and the wire element builds up residue. The first sign is usually a slightly muted flavour, like someone turned the volume down on your e-liquid. Then comes the burnt taste. That is not your juice going bad; it is your coil telling you it is done.
We've seen plenty of people come in thinking their entire JEM pen is broken when all they needed was a coil swap. It is genuinely one of the most common issues we hear about. A fresh coil brings back the full flavour profile of your e-liquid immediately — you will notice the difference from the very first draw. The cotton is clean, the wire is fresh, and everything tastes the way the manufacturer intended.
One honest watch-out: if you chain-vape heavily or use very sweet e-liquids, expect to go through coils faster. Sweetener in e-liquid caramelises on the coil and gunks it up quicker than unsweetened juice. You might get a week out of a coil instead of two or three. That is not a fault with the coil — it is just the nature of the beast. Keeping a few spares on hand means you are never stuck with a burnt-tasting vape.
How to Replace Your Innokin Jem Pen Coil
- Unscrew the base of your JEM pen tank from the battery section. Hold the tank upside down so any remaining e-liquid stays inside.
- Unscrew the old coil from the base of the tank by turning it anticlockwise. It should come out easily — if it is stuck, wrap a bit of tissue around it for grip.
- Take your new Innokin JEM coil out of its packaging. Before screwing it in, add 2-3 drops of e-liquid directly onto the exposed cotton wicking holes on the side of the coil. This is called priming, and it prevents the cotton from burning on your first draw.
- Screw the new coil into the base of the tank, hand-tight. Do not overtighten — you will strip the threads and create leaks.
- Reassemble the tank onto the battery. Fill with e-liquid through the top fill port if the tank is empty.
- Let the filled tank sit for 3-5 minutes before vaping. This gives the cotton time to fully saturate. Skip this step and you will get a dry hit — unpleasant and it damages the coil straight away.
- Start vaping at a gentle pace for the first 10-15 draws. This breaks the coil in gradually and extends its overall lifespan.
