Innokin Cool Fire 2 Design

A grenade.  It looks like a damn grenade, alright? There, now that’s out of the way, we can maybe try and look past the Cool Fire II’s incredibly bizarre appearance and focus on what is otherwise an interesting advanced personal vaporizer.

Oh, and in case you’re wondering, the Cool Fire II isn’t an update to anything.  The Cool Fire 1 is a totally different device which came out at the same time.  I’ll be reviewing that one in the near future as well.

Innokin’s oddly-themed device is on the fairly small size, as it’s powered by an 18350 battery.  It easily fits in the palm of my hand. That also means there’s not going to be a whole lot of run time on a single, small battery.

Despite its fairly small size the… oh hell I’m just going to start calling it a grenade.  The grenade is very hefty thanks to its solid metal construction.

Somehow despite the theming, this grenade is a pretty minimalistic device.  There’s not fancy screens going here. Instead, it relies on the same precision adjustment wheel that the similarly themed Innokin 134 sports.

I’m really beginning to wonder if someone at Innokin isn’t overcompensating for something.

I love it as much on the grenade as I did on the 134. Using the dial, you can select the output wattage from between 7.0 and 12.5 watts in .5w increments.  The motion is very smooth with a tactile click and just enough resistance whenever one of the wattage settings is in the right spots.

One thing to note is that it is possible to set the wheel in between stops.  When that happens the Cool Fire won’t work. For a while I thought mine broke until I worked out that I had the wheel in the wrong position.

Below the click wheel is the fire button. It’s well located for easy use. In the great Innokin tradition, the button is backlit via a color-changing LED that indicates the battery charge through one of three colors. Three clicks of the button will toggle the device on or off.

The top of the grenade unscrews to reveal the hidden eGo connector. Many eGo clearomizers will fit with the top ring in place. If not, the top can be removed. Perhaps it takes away a little of the grenade illusion without the top cover in place.  That’s either a good or a bad thing depending on where you stand.

Over on the bottom is, of course, the battery cap.  There’s nothing terribly remarkable about this cap other than its use of a spring-loaded pin rather than a bare spring.  That configuration does have one downside in that it’s sometimes difficult to screw the cover back on because there is so much resistance in that pin.


Let’s move on to the performance side of this device.  Or, if you’re the impatient type, go visit MadVapes to see if they have any in stock.

Using the Cool Fire II

Here’s the part where I sort of look past the grenade styling of the Innokin Cool Fire 2. Despite being so diminutive, this little grenade packs all the punch of the much larger 134.

iclear 30bThanks to the incredibly impressive 7 amp load rating, Innokin’s grenade can power through just about any sort of clearomizer you can throw at it. Even dual coils are not a problem.

Speaking of which, Innokin always seems to like to debut a new tank (most of them dual coil) with new gear.  The Cool Fire series comes along with the brand-new iClear 30B (see options and price). In this case the B stands for bottom coil, which is Innokin’s first.

Now, I hate to be a tease but I’m not going to go too far into the B’s details so I might be able to give it a proper review down the road. However, I will say it’s a pretty competent dual coil tank and it pairs quite well with the grenade at higher wattages.

Naturally, the big complaint comes with battery life.   You’re simply not going to get a whole lot of run time with such a small battery. Particularly if you’re running it at the higher settings.

Ok, my biggest complaint, I suppose, is that I can’t take this thing to an airport without tazers, a body cavity search and a terrorist watch list getting involved.

Too Long; Didn’t Read

The Innokin Cool Fire II indisputably looks like a grenade. It also packs an explosive punch.  Dammit, I promised myself I wouldn’t make any puns. This is one of these devices that will be polarizing: people will either love it or hate it.  Only one thing is for sure, you can’t hate it for its performance.


  • It looks like a grenade
  • High-performance
  • Completely solid construction
  • Great click-wheel adjustment


  • It looks like a freaking grenade
