Innokin Coolfire IV 100W TC Starter Kit

If you’re familiar with Innokin’s Coolfire IV+, then chances are that you already know how great that product is and how much its users seem to rave about it on a regular basis. I know people who swear by the Storm Edition and take any criticism of it as a personal insult, so yes – it’s that good. Innokin Coolfire IV in whiteWith that noted, Innokin has made a number of advancements in recent months, including the new Aethon 100W-compatible board offering increased temp control. Well, they decided to use that board in the newest incarnation of the Coolfire IV, and that leads us to the product we’re reviewing today. As good as the Coolfire IV+ was, we all know that there was no guarantee that its successor would share its success. So, did it? In this review of the Innokin Coolfire IV 100W TC Starter Kit, we’ll try to get to the bottom of that important question.

Let’s be clear about one thing: after using this box mod device, there is no doubt about the overall performance benefits offered by the Aethon chipset’s inclusion. This is a major upgrade that is going to really catch many Coolfire fans by surprise, as the 100 watts of temperature-controlled power really offers to vape at a different level than what most of those users are accustomed to seeing with their old devices.


The Battery

The device uses a 3300 mAh battery as opposed to the standard 18650 batteries that you see quite often in these types of box mods, so it offers more than enough power to get you through an average day before you have to recharge it during the night. Obviously, heavy use throughout the day – as you might see if you are continually vaping on a road trip, for example, might see you getting less continuous use out of your new Coolfire, but you will still have better staying power than you’ll get with many other products. Plus, there is nothing that says that you have to run the battery completely down, so feel free to recharge any time when you’re not actively using it.

The OLED screen provides a full range of critical information about your device and its usage. You can check the watts, resistance, battery power, voltage, and temperature, as well as your menu of options. All of those options can be controlled using three conveniently located buttons near that gorgeous screen, so there is no fumbling around when you need to make changes. The OLED will also flash codes on the screen in the event any of the device’s protective features are initiated. You can see what those error messages mean by matching the code to the key provided in your owner’s manual.

Temperature Control

There are three temperature settings from which you can choose: The Nickel 200, the Titanium, or the standard Stainless Steel. One thing that really impressed us was the speed at which the Aethon chip responded to our selections – in this case, less than two-tenths of a second from the time we made our selection and the time the device responded. That’s impressive indeed. As for resistance settings, you get unparalleled accuracy at even the lowest resistance ranges, making it easier than ever to ensure that you avoid those horrible dry hits.

That accuracy is necessary for a device like this since it is designed to provide the maximum level of TC you’ll find anywhere in the marketplace today. The Aethon board seems to do an excellent job detecting even the most minute changes in coil resistance and makes precise adjustments to maintain your chosen preferences.


The Design

The design of the Coolfire ivThe body is basically a re-purposed Coolfire IV+, which means that it too has perfectly-placed buttons and dependable quality. With the starter kit, you get the 3 ml tank you need and the iSub tank. Put together, the device is capable of putting out plenty of vapor, though you’re unlikely to be confused for a hookah-smoking caterpillar any time soon. Still, the design is sure to provide you with a rich flavor that quickly bathes your taste buds in the perfect blend of e-juice sensations you need to truly enjoy each draw. 

Of course, the best thing about this device is its accessibility. Innokin tends to approach design from an intuitive perspective, and that leads to products that almost tell you exactly how you should use them. This device is no different in that regard, and that means that it is a great starter kit for anyone who is just getting started with the more advanced vaping offered by temperature control technology.

The device also comes in a variety of colors, ranging from basic black or white to blue or red. That can be important for those who want their vaping experience to be both stylish and enjoyable. Though some might still subscribe to the notion that things like unit color don’t really matter in the end, the fact remains: there’s no reason that the best vaping tools cannot also be attractive pieces of technology. It’s nice to have a company that understands that as well.


So, what we have is a beautiful and elegantly-designed mod that does exactly what you would want from your vaping equipment. It’s light enough to be used on the go, and sturdy enough to last for many years into the future – or at least until Innokin makes the next great vaping mod that catches your eye. At under $50, the Innokin Coolfire IV 100W TC Starter Kit is definitely worth a look!
