Innokin JEM Replacement Coils

The Innokin JEM Replacement Coils are a direct replacement for the coil in your JEM Pen, and there are two to choose from: a 1.6 Ohms KA1 coil and a 2.0 Ohms Ceramic coil. Both are supplied in a pack of 5.

The JEM Pen is a mouth-to-lung (MTL) vape pen, and both coils are built for that draw. They work best with high-PG e-liquid, 50% PG or more, or with nicotine salts.

Optimised at 13W

These coils are optimised for the JEM Pen's output and give full, intense flavour with every puff. The JEM Pen has a 13W constant output, so on that kit there is nothing to adjust. The JEM/Goby gives you a choice of five power settings, from 10W up to 13.5W, along with adjustable airflow.

Five Minutes to Prime

Empty your tank before you change the coil. Turn the pen upside down, unscrew the base and remove the old coil. Screw a new one in, reattach the base and fill the tank. On the first fill, leave it to stand for five minutes before vaping so the coil can soak up the e-liquid, which helps prevent dry hits.

When the Flavour Drops

Keeping the tank topped up helps extend the life of the coil. A burnt taste, or less flavour and vapour than the coil gave when it was new, means it is time to replace it.

The JEM Pen, Tank and Goby

These are compatible with the Innokin JEM Pen, as well as the 510 JEM tank and the JEM/Goby.

KA1 and Ceramic

The 1.6 Ohms KA1 coil gives you plenty of vapour. The 2.0 Ohms Ceramic gives the more cigarette-like experience of the two. Whichever suits you best is the one to choose here.
