As a Vaper, I am always enthused about getting the chance to talk to interested individuals who want to know what I’m “smoking.” There isn’t a day that goes by when I’m not asked, “What’s that thing you have there?”

Vaping has become a big part of my life. Wait, let me rephrase that, vaping has become an integral part of my entire family’s life. Now that vaping has allowed me to banish the demon of smoking back to the hell it came from, why would I not want to share that amazing accomplishment with other folks? To ensure people will to want to ask me about vaping when they see me take an, ‘oh-so-sweet’ toot on my APV, I will take out my Innokin 134. This monster of a PV has always been my go-to “vape conversation piece.”

That is, until now…

Dave from the Spinfuel main office sent over Innokin’s newest addition to their line of advanced personal vaporizers, the Cool Fire II! The Cool Fire II is the ultimate conversation starter. When someone sees it, they’re definitely going to want to know what is that I have in my hands.

The Unboxing

I was actually a little bit disappointed in the packaging that the Cool Fire II comes shipped in. I was really expecting another of those nice hard cases that Innokin has been shipping their higher priced PV’s with. Instead the Cool Fire II comes in a plain brown box with black writing on it. Inside the box you will find the Cool Fire II, an instruction manual, and the new Innokin iClear 30B.Cool Fire 2 Review by Steve Kaderabek for Spinfuel eMagazine

The first thing that you’re going to notice is that this thing honestly looks like a small hand grenade! The one that I received is completely blacked out (murdered out? Is that what the kids are calling it these days?) except for the words Cool Fire II embossed on the nameplate.


The Cool Fire II is a variable wattage device, which features a selector wheel exactly like the one on the Innokin 134. The selector wheel ranges from 7 watts to 12.5 watts, allowing all different ranges of atomizer resistances to be used.

The Cool Fire II has a standard 510/ego connector that is surrounded by the typical Innokin beauty ring that we have all come to love. With the beauty ring, you can achieve that “flush mount” look with almost any atomizer of your choice. The outer shell of the Cool Fire II is completely metal and has vent holes in the battery cover in the event that a battery should short and violently attempt to turn this into an actual hand grenade.

This is not a lightweight PV and it feels extremely sturdy in the palm of your hand. The Cool Fire II uses a tension system that looks as if it’s a small cap over a strong spring. They are great at doing the job of holding the battery in place. Sometimes, however, they do their job a little too well and start pushing the end cap into the battery. The only plastic part that I could find on the exterior of the Cool Fire II is the power button.

Cool Fire 2 Review by Steve Kaderabek for Spinfuel eMagazineAs on all their recent devices, Innokin has went with their standard three click on, three click off power scheme. They have also stayed with the color system that lets you know how much battery charge is left when you fire the device. You’re going to get one of three colors when push the fire button-Green, meaning the battery has a full charge. Yellow, meaning it’s at a fifty percent charge and red indicating a genuine vape emergency! The dreaded “this battery is low and it about to stop working” warning that nobody wants to see.

The Innokin Cool Fire II was designed with safety in mind with its reverse battery protection circuit. This will not allow a battery to work if put in upside down. Another safety feature of the Cool Fire II is the built in 7amp fuse which will cut out if more than 7amps is trying to be drawn through the device. It also features short circuit protection, which really comes in handy if you build your own coils. If by chance your coil shorts out this safety feature will not allow the short to affect the battery.

Innokin also added industry standard vent holes to the battery cover, just in case a battery were to vent. The Cool Fire II also has some user safety features, one of these being the ten second firing cut off. This feature only allows the power button to be pushed for ten seconds at a time and then cuts the power off. Another safety feature that Innokin built into the Cool Fire II is the selector wheel warning. If the selector wheel is bumped in between two wattage settings, the power button with flash and not fire.

The iClear 30B

Before I cover my real world experience with the Cool Fire II, I need to talk about the atomizer that comes included with the device. The Cool Fire II comes with an Innokin iClear 30b. This is a dual bottom coil clearomizer, similar to the Kanger ProTank 3. With a capacity of 3ml and being a bottom feed dual coil tank the iClear 30b is a step up from the rest of the iClear series. The iClear 30b is the perfect match for the Cool Fire II in not only looks, but with vapor production as well. The dual wicks allow for the perfect flow of e-liquid to the coils, which virtually eliminates the chance of getting a dry hit. Innokin has really stepped up their game with this tank.

Real World Experience

Now that I have covered the technical aspects of the Cool Fire II and iClear 30b, let’s talk real work, day-to-day usage. Normally I carry a ProVari in 18650-mode with a Kayfun Lite. But for the last ten days I have exclusively used the Cool Fire II with an iClear 30b riding on top. Taking this PV out and about is an absolute treat.Cool Fire 2 Review by Steve Kaderabek for Spinfuel eMagazine

First you have the comfortable size of it. Even at its slightly heavy weight, it feels natural in your hand. The only real problem is that it is not a pocket mod (unless maybe you’re wearing cargo pants.) One problem that most other mods run into is finding a place to stand it up where it won’t be bumped and knocked over. This is not a problem with the Cool Fire II. The wide base of this device serves as a stable stand. As I stated earlier the Cool Fire II is an 18350 battery (flat-top) PV, so I was not sure how it was going to fair for me out and about on a normal day.

With a freshly charged battery I easily got six hours of vaping time while at work. On the flip side of that I get a few hours while sitting at home where I do my heaviest of vaping. This is not a major issue as I always carry at least one spare battery in the event that I need it.

Taking the Cool Fire II in the car was never an issue either. The size of it made it a perfect fit to ride along in the cup holder. I honestly had no issues with taking the Cool Fire II out in place of my usual all day devices. The one major thing that I did notice while taking the Cool Fire II out into the world was all the interest in it. No matter where I was, be it at work, the grocery store, or even just standing outside, someone was always asking about it. This was a great opportunity to discuss my love for vaping.

Comfortable fit

Large stable base

Easy wattage selector

Versatile adapter

Built in safety features

Some Vapers may want Variable Voltage, this is VW-only

Conclusion & Buying Advice

I feel this is a great advanced personal vaporizer for the advanced Vaper and for the Vaper stepping up from a basic PV. Even though I personally believe it would be a better PV if it were designed to be used with an 18650 battery, the 18350 does suit the overall aesthetics of the device well. The 510/ego connector makes this perfect for a variety of tank systems if so desired.

I feel Innokin paired it with just the right tank by including the IClear 30b. This combination makes for one great all-day device if you carry at least one spare battery.

I would highly recommend the Cool Fire II to anyone wishing to be approached about vaping. The very design of it is going to pique onlookers’ interest in what you have.

The Innokin Cool Fire II is available now at MyVaporStore for $79.99 in black or jungle camo. The box includes the Cool Fire II and one iClear 30b. I suggest picking up a twin-pack of fresh 18350 IMR batteries ‘flat-top’ ($11.85).

I like to include at least one safety precaution in my reviews as they are usually written about rebuildable devices. I feel a need to do so with the Cool Fire II as well. I highly recommend against waving the Cool Fire II around unless you want to draw law enforcement out. In this day and age of violence it would not surprise me if someone were to mistake it as a grenade. Consider yourself warned.
