The Innokin Coolfire Z80 Zenith II Kit is a collaboration between Innokin with their Coolfire Z80 mod and the Zenith 2 tank from Innokin along side PBusardo & The Vaping Greek, two respected reviewers and product designers from the states. A kit made by vapers for vapers. The Coolfire Z80 mod features the new Fourier technology which can extend coil life and flavour using alternating current to produce a waveform that runs continuously while you vape. The Z80 Mod also features a Refresh mode, once the mode is on is improving the wicking and the extend coil life. Refresh mode powers the coil at 40% with alternating current drawing in more liquid into the coil. The Zenith II Tank has a MTL draw (mouth to lung) and an airflow control to change your vape experience all the way up to a restricted direct to lung vape. Zenith II Tank is compatible with all of the Z-Coil aka Zenith coil line. The Mod requires 1 x replaceable 18650 battery, just twist the battery cap door and quickly replace the rechargeable 18650 batteries. The Coolfire Z80 Mod also features a Type-C charge port for a quick charge.

Battery Safety

This device uses external cells 

It is not recommended that users charge their separate cell devices with a usb lead in to the device. These devices can be charged via usb as an emergency measure but is not recommended as a permanent solution. This is not a line to sell chargers there are significant reason why it should be done externally. Do not assume that it is safe. These batteries are not made for vaping and the manufacturer has no idea what cells you are using. Best to use the safer solution of a named quality charger.

1. Most vapes cannot balance charge more than one cell. One cell is charged and then after that the next cell is charged. All of the drain, excess heat and over use of that one cell causes strain on that 1st battery in the vape and ultimately leads to the demise of that 1 battery leading to the need of a new pair. If lucky it will just stop working if unlucky the cell may go into melt down 

2. If your batteries are not the same age, i.e. the same amount of charges, the same amount of use and charged together for their whole lives then they are unbalanced. Meaning they cannot deliver the high output required by your vape. This will lead to low performance and low battery life. 

3. External chargers let you monitor the charge going in to your cells. Good quality chargers will put what is needed in as opposed to as much as possible as fast as possible which can caused issues. A good charger will slow the charge rate down to recondition a bad cell. Internal charging will not do this. Using a good external charger could mean your batteries getting you through a day away from your charging equipment or not. Ultimately it is up to you how safe you want to be. Yes an external charger may sound like a hassle to you but it depends on the risks you want to take. 

Please make sure your external cells have perfectly intact wraps on them If they have any of the metal showing under the wrap or the insulator on top please either re wrap or buy new cells PS This is not to scare you If you have any doubts about your charging routine just ask. Batteries get warm when they charge but if they are red hot then its time to look into it
