The Innokin CoolFire Mini Zenith D22 Kit is a tiny, easy-to-use device which will fit easily into a pocket or bag. It comes with an ergonomic design that fits neatly into the hand and is easy to use. The kit can be used either in voltage or wattage mode.
Leak and noise prevention
The tank comes with an improved chimney design which automatically closes off the air holes when filling, which prevents e-liquid leaking and gurgling (which occurs when e-liquid is trapped in the chimney).
The tank also comes with precision adjusting airflow, which means you can adjust the airflow to get a tighter or airer vape, depending on your preferences. Meanwhile, the twist top refill mechanism means it is easy and quick to fill up the tank.
The tank comes with Innokin’s Plexus Coils - the first to be designed for a mouth-to-lung vape. The coils mesh design leads to a larger surface area which means you can enjoy better flavour and a longer coil life - meaning fewer replacements, which can save you money over the long term.
Who’s it for?
The CoolFire Mini Zenith kit is easy to use, and provides a mouth-to-lung hit. That makes it great for both newer vapers and those with some experience. With wattage range of 6-40 watts, vapers who prefer large clouds of vapers would be better off looking for a kit with more power.
Mouth to Lung Vaping

Using Your Tank: Best Practice
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.
How To Maximise the Life Of Your Coils
Coils don't last forever, but by taking a few easy steps you can often extend their life!
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.
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.
For more advice, see Seven Easy Ways to Stop Your Coil From Burning Out.
