The Innokin Kroma 217 utilises Innokin’s innovative Coil+ and Refresh modes to provide improved flavour and long-lasting coils. Coil+ mode automatically primes your coil after each use, while Refresh mode can be manually activated to prime the coil and refresh flavour whenever you choose.
Able to use 18650, 20700 or 21700 batteries (not included), the Kroma 217 mod can output up to 100W* of adjustable power. Choose the 18650 for the lightest battery or the 21700 for maximum battery life. The external battery design also means you can vape without interruption with a simple swap of the battery. (*100W of power with 21700 battery - when using 18650 battery max power is 80W.)
The Kroma 217 kit includes the Z Force vape tank, able to create large, dense clouds and a flavourful Direct-Lung (DL) vape thanks to the compatible low-resistance ZF coils. (See more about DL vaping in the FAQs below.)
ZF coils feature a unique DuoPrime mesh design - with 2 layers of mesh heating at different rates to provide enhanced flavour and vapour production. The tank’s adjustable airflow ring means you can precisely tailor your vape between airy or more restricted.
Filling the Z Force tank is made easy and mess free thanks to the convenient top filling design - with a built in membrane that prevents leaks.
As well as the included tank and coil, the Kroma 217 mod’s threaded 510 connection allows it to be paired with most other vape tanks.
Compatible E-liquids & Coils
The included Z Force tank works with the ZF coil range and is recommended with high VG e-liquids with a VG:PG ratio of 70:30 and above.
- 0.2Ω ZF coil: 50 - 80W
- 0.3Ω ZF coil: 30 - 45W
Who is the Innokin Kroma 217 kit for?
The Kroma 217 is a great choice for experienced Direct-Lung vapers who value large clouds and great flavour.
What e-liquid can I use with the Innokin Kroma 217 kit?
When used with the included coils, the Z Force is best used with high VG e-liquids, with a VG:PG ratio of 70:30 and above.
What are Coil+ and Refresh mode?
Coil+ and Refresh are modes that both manually and automatically prime your vape coil for improved flavour & longer-lasting coil life.
Both modes send a pulse to the coil at 40% of the wattage currently being used for 0.4 seconds. This draws more liquid into the coil to keep it saturated and reduce carbon build up.
When activated, Coil+ mode will automatically do this after each use, while Refresh mode is manually activated so that you can prime the coil as often as you like.
What is the difference between 21700 and 18650 batteries?
21700 batteries are larger than 18650 batteries, with a size of 21 x 70mm, as opposed to 18 x 65mm. They also have a larger battery capacity, which means they can go for longer between charges. The exact battery capacity depends on the brand and battery used.
Can I charge my Innokin Kroma 217 overnight?
Lithium batteries should not be left unattended when charging. It is also important to use an appropriate charger, such as the Veho Plug Adaptor. For more information see our battery safety infographic.
Can I wash an Innokin Z Force tank?
Yes. Remove the tank from the device, remove the coil and empty out any e-liquid. Wash the tank out with warm (not boiling) water and ensure that it is fully dry before using it again. You can also clean the connections out with cotton to remove dust.
How long do the coils last?
Coil life depends on many factors, including how long you puff for, the e-liquid you use and the wattage you use your coil at. Low resistance coils, which are used at higher wattages, will not last as long as high resistance coils.
You can extend coil life by:
- Priming the coil before usage
- Using e-liquid with the right VG:PG ratios
- Not going above the recommended wattage
- Topping up your tank so that the coil never dries out
With care, the included ZF coils should last several days before needing to be replaced.
What is Direct-Lung (DL) vaping?
In Direct-Lung (DL) vaping you inhale vapour into your lungs in one continuous breath.See MTL v DL for more information.

Follow these simple steps to get the most out of your tank.
- When filling, always avoid getting e-liquid in the centre tube.
- Don’t hold down the button before inhaling.
- When attaching the coil, screw it in firmly but don’t over-tighten.
- Make sure you use the right power settings. If unsure, check the manual or start with a low power setting and work your way up till you get the right hit.
The Right and Wrong Ways to Treat Batteries!
Battery Safety Information
- Ensure you use the correct charging equipment for your e-cig (see below).
- Charge batteries on a hard surface.
- Turn your battery off when not in use.
- Use damaged batteries.
- Leave charging batteries unattended.
- Allow contact between your batteries and water.
- Carry in a pocket with coins or keys. (The Kbag is a great way to carry batteries securely and safely).
- Expose your battery to sunlight, extreme heat or cold.
For more information see our E-Cig Battery Safety Infographic.
Recommended Charging Equipment
We recommend the Veho Plug Adaptor and the Nitecore Intelli charger (for external batteries). Both are high quality devices from a reputable manufacturer, have performed well in testing and have the right voltage output for e-cigs.
Extending Your E-Cig Battery Life
With regular usage, your e-cig battery will usually last for 3 months, although they can last longer. The following steps can help extend the life of your battery
- Cleaning your battery terminal. The most effective way to do this is to use a cotton swab soaked in alcohol, but you can also clean it with a tissue or a cotton swab.
- Keeping your battery charged. Keeping some charge in your battery can extend your battery life, especially if you go for some time without using it.
How To Maximise the Life Of Your Coils
Always allow your e-liquid to soak into your coil for at least five minutes before using it. This will help prevent your coil from burning out.
When you have a more powerful coil, or one with more wicking material, it’s also a good idea to prime it by applying a few drops of e-liquid into the coil holes before filling.
Once you’re using the device, it is important to keep your tank topped up. If the e-liquid gets too low and the coil is exposed, the coil can burn out.
