The Innokin Coolfire Z50 mod has a wattage range which is suitable for both MTL and restricted DL vaping and comes with simple and intuitive controls and user interface. The mod works well with existing Zlide tanks and coils as well as the included Innokin Zlide tank, but handily is compatible with any 22 mm and 24 mm tank. The Z50 comes with a 2100 mAh capacity, which means it will last most vapers a day of usage before needing charging.
The mod also comes with an off button at the base, which enables you to switch off the device when carrying it in your pocket, helping to ensure longer coil life.
The included Innokin Zlide tank comes with a push-to-open fill mechanism, which opens a filling port for quick, easy and mess-free filling. The tank has a replaceable glass (included with the kit), meaning you won’t need to replace the whole tank if the glass is cracked.
The tank is also designed to allow for easy coil changes, even when the tank is full, which means you won’t waste any e-liquid.
Who is the Innokin Coolfire Z50 Kit for?
The Coolfire Z50 is a great choice for vapers looking for an intuitive but versatile device which is capable of both a MTL or a restricted DL vape.
How do I fill the tank?
Remove the drip tip, then push the top cap to the side to open up the side fill port.
How do I remove the coil?
Unscrew the bottom of the tank, and pull the coil out.
How do I turn the device on or off?
At the bottom of the mod there is a button marked on/off. Ensure this is clicked to on. You can then turn the device on or off by clicking the fire button 3 times. We advise using the on/off button when carrying the device in a bag or pocket to avoid accidental firing of the device, which can damage the coil.
What e-liquids can I use with the Innokin Zenith Pro?
That all depends on the coil you are using. Higher resistance Z (Zenith) coils, such as the 1.6 Ω Z coil, are suitable for e-liquids with a VG:PG ratio of around 50:50. Lower resistances Z coils, such as the 0.48 Ω Z 3d Mesh coils, work well with high VG e-liquids, such as those with a VG:PG ratio of around 70:30 or 80:20.

- Don’t hold down the button before inhaling.

[Advanced Tanks] 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!
First, it's well worth priming your coil before you use it for the first time. Simply add a couple of drops of e-liquid to the ports in the coil and in the opening of the coil head.
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.” .
