Innokin Jem Replacement Coils

The Innokin JEM Coils are replacement atomiser heads designed for the Innokin JEM Pen-style vape system. These low-power coils are intended for mouth-to-lung (MTL) vaping and are available in 1.6Ω and 2.0Ω resistance options, depending on the version selected. Each pack contains five replacement coils, giving existing JEM users a convenient supply for routine coil changes. 

Key Features

• Genuine Innokin JEM replacement coils.
• Designed for the Innokin JEM Pen system.
• 1.6Ω and 2.0Ω resistance options.
• Pack of five coils.
• Organic cotton wicking material.
• Stainless-steel coil barrel.
• Screw-fitting installation.
• Designed for low-power MTL vaping.

Choosing the right resistance

The JEM coils are available in 1.6Ω and 2.0Ω versions, with both designed for lower-power MTL vaping. 

The resistance you choose should match the coil version and operating range recommended for your device. The 1.6Ω option is commonly used at around 10–13.5W, while the 2.0Ω version is another low-power option for the JEM platform.

If you are replacing an existing JEM coil, the simplest approach is to match the resistance already installed unless your device manual states that another option is supported.

Organic cotton wicking

JEM coils use an organic cotton wick around the heating core. Multiple e-liquid ports allow liquid to reach the coil during use. As with any replaceable coil, the wick needs to remain saturated before vaping. After fitting a fresh coil, fill the tank and allow enough time for the cotton to absorb e-liquid before taking repeated puffs.

A burnt taste, noticeably weaker flavour or reduced vapour production can indicate that the coil is reaching the end of its usable life. Replacing the coil rather than continuing to use a depleted head helps restore the intended performance of the JEM system.

Installation

The JEM coil uses a screw-fitting design. Remove the relevant tank or pod section from your JEM device, unscrew the used coil and fit the replacement securely without overtightening.  Reassemble the tank, fill with suitable e-liquid and allow the coil to prime before use.

Who are these coils for?

These replacement coils are designed for existing Innokin JEM users who need spare atomiser heads without replacing their complete device. With their higher resistance and low-power operation, the JEM coils are particularly suited to users who prefer a controlled MTL draw and moderate vapour production. 

Compatible E-Liquids

JEM coils are intended for low-power MTL vaping. A 50/50 VG/PG e-liquid is a practical option for this style of coil because it wicks readily through the smaller coil openings. Match nicotine strength to your existing setup rather than increasing power to compensate for a stronger liquid.

Compatible Devices

• These coils are designed for Innokin JEM devices, including the JEM Pen platform. 
  
• They are not interchangeable with other Innokin coil families such as PLEX, T20 or Z Coils. Always check the exact device and coil name before ordering to ensure compatibility.
