The Innokin Coolfire Z80 is a new starter kit incorporating the Zenith II tank. This tank is capable of supporting RDL and MTL vaping, incorporating smaller airflow holes than its predecessors, but also having wider slots than the Innokin Zlide. Additionally, the mod includes a new power mode that is among the first of its kind.

Innokin Coolfire Z80 Zenith II Review

The Coolfire Z80 is an 80 watt mod that comes with the Zenith II tank. A 18650 battery powers the mod, and the tank is compatible with all of the Zenith coils.

Additionally, the mod has several power modes, and both the mod and tank are built to a high standard, resulting in them being highly resistant to accidental drops. Overall, this is an excellent starter kit that has been highly satisfactory.

Power Modes

The vape has FØ and Refresh modes. The FØ mode is a new power mode that uses an alternating current that lets users select the frequency in Hertz (Hz). The best settings are 20-50 Hz for direct-to-lung (DTL) and 51-100 for mouth-to-lung (MTL).

This power mode does not affect the wattage, nor can it, but Innokin claims that the alternative current improves the flavor. It is hard to tell if FØ mode enhances the flavor. The flavor is very good, do not get us wrong, but several other factors also determine whether the flavor will be acceptable.

Refresh mode should be easier for everyone to understand. This mode works by making the mod fire at 40 percent of the chosen wattage. This feature allows the coil to continue providing decent levels of flavor even when the coil is approaching the end of its life.

Internal Building Quality and Design

Everyone should be happy with the build quality and overall design, but some will not like the very generic color choices. They are black, white, dark gray, and light gray. Some other colors should have been added, like red, blue, and yellow, but oh well.

Otherwise, the build quality and design are acceptable. All the buttons are clicky and responsive, and the mod is lightweight and pocketable.

The build quality of the tank is equally impressive, thanks to the glass, which is encased in protective metal. This feature gives the glass added protection against accidental falls and knocks.

Innokin Coolfire Z80 Kit Battery

The vape is powered by a single 18650, and it will offer a respectable amount of battery life so long as the mod is not constantly maxed out. It would have been nice had it been compatible with 20700/21700 batteries, though. The 18650 is kept behind a screw cap. The cap screws on and off without any problems, and it holds the battery in place.

Battery Level Indicators and Screen

The screen shows everything the user needs to know while vaping. The battery life indicator is in the upper right corner, and the selected power mode is in the opposite corner.

In the center is the wattage and beneath that is the puff timer and counter, coil resistance, and voltage output. There are also several sub-menus for controlling the vape, including options for selecting power modes and other settings.

Zenith II Tank

The Zenith II is the best part of the starter kit. It holds 5.5 ml of juice, which is the ideal capacity, and it comes with two drip tips, one for MTL and another for RDL vaping.

The top and bottom of the tank are easy to grab, and it is also easier to disassemble, which makes cleaning simpler. It is top-fill, and the fill port is exposed by rotating the top cap.

Also, the glass can be replaced, which is worth mentioning because there are a few tanks with non-replaceable glass.


This tank is for people who prefer RDL and MTL vaping, and it is not a direct-to-lung tank. There are three holes for MTL and a larger slot for RDL. The airflow is changed by rotating the airflow control ring back and forth. The airflow is smooth and silky, and the airflow is just perfect on MTL. Not too loose, but not too tight either.

The Z-Coils

The starter kit comes with a 0.3 ohm kanthal mesh and a 0.8 ohm kanthal coil. The 0.3 ohm coil is rated for 30 to 40 watts, and the 0.8 ohm coil for 15 to 18 watts.

The 0.3 ohm coil is the lowest resistance coil in the Z series, and it is an excellent coil for RDL vaping. It has decent flavor and provides high amounts of vapor. As for the 0.8 ohm coil, it is for MTL lovers who want a slightly warmer vape than what the higher resistance coils can provide. It is also no slouch in the flavor category.

If these coils are not satisfactory, there are five other coils in the Z Series, with resistances as high as 1.6 ohm.

Compatible Juices

This tank and the Z Series coils are compatible with a wide range of liquids.

  • The 0.3 ohm coil is best used with 70/30 vegetable glycerin to propylene glycol liquids, as these provide the optimum balance between flavor and vapor.
  • The 0.8 ohm coil is best with 50/50 liquids because they provide the best possible flavor, and on low wattage vaping, vapor production is not that important.

Zenith II vs. Zenith Original vs. Zenith Pro

The first thing most people will notice is that the original Zenith and the Pro versions have larger airflow holes because they were made for DL vaping.
The Zenith II’s airflow slots are narrower to achieve RDL airflow.
Another thing people will notice is that the Zenith II is easier to take apart and much easier to clean as a result.
Also, the glass can be replaced.

How to Use the Innokin Coolfire Z80 Kit

Most box mod starter kits are not as hard to use as many think. Just learn the button combinations and understand and respect the device’s abilities and limitations. Everything else will be fine. Follow these steps to operate the mod and tank:

  1. Choose a coil and prime it by dropping several drops of liquid into the wicking, and then push the coil into the tank’s base. Make sure the flats of the coil align with the notches in the tank’s base.
  2. Fill the tank by turning the top cop to expose the fill port. Pour liquid inside until the tank is filled to capacity.
  3. Allow five to ten minutes to pass before vaping the tank so that the coils have time to absorb the nicotine liquid.
  4. Insert a charged 18650 battery into the vape by unscrewing the door and putting the battery inside. The battery can be charged with a wall charger or by plugging the USB cable into the port at the base beneath the firing button.

Button Combinations

  • To turn the mod on/off press the power button 3 time
  • To display battery life, coil resistance, and the puff count click the power and up buttons
  • Push the power and down buttons to lock the mod and still fire it
  • Click the up and down buttons to enter the main menu
  • The user can enter the FØ, power, and refresh submenus in the main menu.

Competing Products

Innokin Coolfire Z80 Kit vs. Vaporesso Gen Nano Kit

There is much to be said for the Gen Nano, especially all the power modes it has, including the power ECO, DIY, and smart TC modes. What may be the deciding favor, though, is that it has a built-in 2,000 mah battery instead of an 18650.

Vaporesso Gen Nano Colors

As for the tanks, the Zenith II is a much better tank, mainly because it has a much higher juice capacity. The Gen Nano’s GTX 22 tank has a maximum juice capacity of 3 ml. Mods that can put out 50 watts or higher should come with a 4 ml glass at the minimum.

Innokin Coolfire Z80 Kit vs Innokin Sensis

The Innokin Sensis is a tank-pod mod with 3.1 ml capacity and a 3,000 mah internal battery. It is an excellent alternative to the Coolfire Z80 for those who like Innokin’s vapes but prefer pod mods.

Innokin Sensis 40W Colors

It is good at RDL, DL, and MTL vaping, producing outstanding flavor and clouds. Its most significant advantage over the Z80 is that it is around $20 cheaper.

Zenith II vs. Innokin Zlide

The Zlide is a pure MTL tank, and it helps to produce high levels of flavor when paired with Z Series coils 0.8 ohms or higher. However, people looking for a tank that can do RDL and MTL should go with the Zenith II.

Final Thoughts Innokin Coolfire Z80 Kit

It is hard to find anything to complain about when looking at the Innokin Coolfire Z80 Kit. The vape puts out a respectable amount of power, and it comes with an outstanding tank that can handle MTL and RDL vaping, not to mention it produces extraordinary levels of flavor and silky smooth vapor. The only problem is that the vape does not have temperature control. Other than that, no other cons.
