The Cool Fire IV 100W Kit

The Cool Fire IV TC 100 is a 100W Starter Kit that uses a vertically positioned, sub-ohm coil for an incredible vaping experience. With Innokin’s very popular “no-spill coil swap system,” you can easily switch out your stainless steel coils without any hassle.

Featuring a Pyrex glass Innokin iSub Tank with a 3mL liquid capacity, adjustable airflow, and easy top filling, this mod is great for vapers who are just starting out or trading up, and want a premium TC mod to use.



If you do not need 200W or 228W mods and simply do not use your device at such high levels, you will love the Innokin Cool Fire IV. The combination of the Cool Fire IV TC 100 mod itself with the brand new iSub V Sub-Ohm Tank by Innokin, provides a completely new and powerful experience. With an ability to reach up to 100 watts, including temperature control, and all of the benefits of a versatile tank, adjustable airflow, and easily swapped coils, this Cool Fire IV is built to perform.


You can control and view the usage of your Innokin via the OLED display that is located on the side of the box mod just above the micro USB port and the two physical buttons near the bottom of the mod. The fire button is located just above the display, where your finger rests — it is a very ergonomic and natural position.



As for the tech behind it, the Cool Fire IV is powered by an ultra-fast, advanced Aethon chipset with 100W of power — using ClearWave noise cancellation technology, vaping is quiet and discrete. The curve of the mod is designed to fit perfectly in your hand.

The minimum resistance of this mod is 0.1 ohm — you can use different coil types, such as Nickel (Ni200), Titanium (Ti), and Stainless Steel 316 (SS316). In the Technical Specifications and Features (seen below), you can view the resistance settings recommended for TC Mode. Stainless Steel coils (such as the one included in the starter kit), offer a much larger range of resistance than Nickel and Titanium.


Finally, the battery — this mod is very powerful and features a built-in 3300mAh battery. That is much more powerful than most mods are offering — especially in this price range. You can vape for many, many hours on a single charge. And using the micro USB port located on the side of the mod, you can easily charge up while keeping your mod standing upright, as opposed to having to lay it on its side.
