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
Mouth to lung vaping, refers to inhaling the vapour directly into your mouth before taking it into your lungs. You can read a fuller explanation on our blog here: Mouth to Lung v. Direct to Lung - what’s the difference?

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.

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.
