As you can see, Innokin CoolFire IV is a performance-oriented device. Together with an iSub V Tank, the Cool Fire IV make an even more powerful tandem. The Cool Fire 4 tank can hold up to 3.8 ml e juice.

The base diameter of the mod atomizer is only 22 mm. There are well-thought dual bottom airflow slots that have stoppers at both ends. Also, there is a non-adjustable 510 pin in this top-fill device.

Cool Fire IV Design

Innokin Cool Fire IV TC100 is built for performance, but it doesn’t mean that the style is compromised. All of the Cool Fire IV box mods have a similar basic design, be it the Storm, the TC 18650, the Plus, or the TC100 box mod. Each of the mods has well-rounded edges, which makes it easy and pleasant to hold.

The fire button is located along the top edge of the mod, which allows every user to use the device comfortably regardless of the size of their palms and fingers. It is equally comfortable to fire the device with a pointer finger and with a thumb.

Another cool thing about the Innokin Cool Fire IV design is its small OLED screen. Though small, it shows you all the data you need to know about your mod, like battery life indicator, coil resistance, battery voltage output, shut down timer, wattage and temperature settings (applicable for TC mode).

The screen is bright enough for you to read it clearly day or night. Speaking of the shutdown timer, there’s one more cool feature of the mod you should know. It shuts down automatically after it is idle for ten seconds. It helps to save the battery a lot.

When it comes to style, the Innokin doesn’t give you a lot of options. The Innokin Cool Fire 4 comes in black, blue, red and stainless steel colors. Some of the Cool Fire 4 reviews mention that this mod is rather plain-looking and that the current color range is not enough.

However, there are many satisfied users who are not looking for a flashy device but simply seek the convenience of use and good functionality.

Innokin Cool Fire Quality

Even though the Cool Fire 4 kit may be not one of the most stylish-looking box mods, it is for sure one of the best in terms of build quality and performance. This solid mod does not feel plastic, it does not rattle, and the power button does not make any weird sounds as you press it.

The only not so great thing we’ve noticed about this box mod is that its 510 connection is protruding. It probably prevents the atomizers from scuffing up the paint from the mod top. In any case, some users might see this gap as a design defect.

iSub V Sub-Ohm Tank: Overview

Having decided to purchase the Cool Fire 4, you can either simply get it as a mod or purchase a vape starter kit that features the iSub V sub-ohm tank as well. This atomizer is worth its money for a number of reasons. First of all, it’s easy to use thanks to the top-fill design. Also, the auto shut off feature would not let you flood the coils.

Coil Replacement

It’s easy to replace the iSub V coils. Unlike it is with many other tanks, you don’t need to empty the tank before the replacement. To remove the coil, you simply need to take off the bottom cover (airflow controls) and take out the coil from the bottom.

That’s it! When putting another coil in, pay attention to the abs on the coil and the groove on the atomizer. They should line up to prevent any leaking.

Cool Fire IV TC100 Vaping Experience

The Cool Fire 4 TC 100 is a mod that’s easy to understand, operate and maintain. Yet, it’s a very powerful and robust mod that can deliver the best vaping experience to every beginner and even to the experienced vapers. The mod is ready to use the moment you get it and fill the vape tank with the e-juice, which is pretty cool.

CoolFire IV heats up so quickly you won’t even notice it. As for the vapor production and flavor, there is nothing to complain about, as the mod does its job well.

Final Thoughts

All in all, the Innokin Cool Fire IV TC 100 is a powerful and ergonomic device that has a long battery life and charges quickly. This mod has an accurate temperature control mode as well. It’s easy to fill the e-liquid and replace the coils quickly when needed. One more reason for buying it is the iSub V tank that comes with the starter kit.

However, you should take into account that this powerful mod is not the best when it comes to design. The visible gap between the mod and the atomizer can be a disappointment for some users. There is also no lock for temperature control.

We hope that this review will help you decide whether the Cool Fire TC 100 is the right product for your vaping needs and style.
