Cool Fire IV Plus Storm Edition by Innokin

The Cool Fire Plus was a great looking device but the Storm Edition is even better with its slightly glossy white and black finish. It is exactly the kind of thing your friendly neighbourhood Stormtrooper might use assuming Lord Vader ever allows him/her time off to vape!

Cool Fire IV Plus Storm Edition looks and build quality

In my opinion the Cool Fire Plus was a great looking device but the Storm Edition is even better with its slightly glossy white and black finish. It is exactly the kind of thing your friendly neighbourhood Stormtrooper might use assuming Lord Vader ever allows him/her time off to vape!

In fact the whole device practically screams “Join the Empire, betray your family and friends, learn how to miss with a blaster and burn down Tatooine homesteads while gunning down farmers and innocent Jawas in between your vape breaks!” Okay that is probably going a little too far but you get the idea!

This device is impressive and has an excellent small form factor. The fact that it is nicely curved means it fits perfectly in my hand. The build quality is excellent and has a really nice weight to it. It is a little heavier than some other devices but not uncomfortably so. Instead it gives a certain amount of reassurance that it will be durable and I suspect it could happily take a few knocks.

The device features three buttons and all of them are completely rattle free. The fire button feels especially solid and has a good feel to it. The 510 pin is spring loaded and all of my atomizers sat flush on this device. In addition there are three small channels cut to provide bottom airflow if needed.

The painted Stormtrooper style finish is nicely done and does not appear to tarnish. The internal battery is 3300mAh so this device will easily last all day if you are a moderate vaper and running your atomizers at lower wattages. One side of the device has excellent venting for the battery featuring forty four air holes in two sets of twenty two.

The OLED screen is superb being both large and bright. All of the typical information is displayed: coil resistance, wattage, and voltage. In addition it also displays the battery charge. The front of the device features the Micro-USB port so you can conveniently charge the battery while it is stood upright. The included pass-through technology also allows you to vape while you charge. The Cool Fire IV Storm Edition just like the standard version is loaded with safety features to give you complete piece of mind.

The package also includes the iSub G tank which makes this a great setup for new vapers!

Operating procedure

The Cool Fire IV Plus Storm Edition is very easy to use making it ideal for new vapers. The manual is thorough with everything clearly explained so I will only cover the basics here.

  • Three clicks of the fire button switches the device on/off.
  • To swap between Variable Wattage and Variable Voltage mode hold the fire button and the plus button down together for one second.
  • To adjust Variable Wattage or Voltage press and hold the plus or minus button for one second and then use the plus or minus buttons to adjust to your liking.
  • Hold the plus and minus buttons down together for three seconds to flip the OLED display.

I will be honest and say it took me a few minutes to get used to having to hold one of the adjustment buttons down to change the wattage but this is only due to me being used to other devices. In many ways it makes perfect sense since you won’t accidentally change your power setting while the device is in your pocket. Essentially it doubles as a locking feature but Innokin do advise that you switch the device off when not in use.

One other great feature is that the device has an LED light behind the fire button and it changes colour alerting you to the current charge of the battery. At full charge it lights up green, at 50% charge yellow and finally red when the device needs charging.

Cool Fire IV Plus Storm Edition performance

Offering up to 75W of power means that this device will suit most typical users and the resistance range means you will have no issues using any atomizer. I have used the Cool Fire with the included iSub G tank, my Achilles II RDA and also my GP Heron 2.0. I have had absolutely no problems at all and this device has been a real pleasure to try out!

Bear in mind that the device does not include temperature control but let’s be honest here not everyone requires that feature so I don’t feel the device is less appealing without it.

Battery life has been very good but I have only been using it at 16-35W, it goes without saying that if you use it at higher wattage the battery will drain much faster.

This device was great to use while out walking due to its excellent size and the fact that it is so comfortable to hold. The iSub G tank is decent and has very good flavour but it does have a couple of shortcomings, namely the lack of top filling and it can also be a little bit messy if you are not careful when refilling. Nevertheless it does offer a very enjoyable vape and the airflow while airy can be reduced to get a decent but slightly loose mouth to lung vape. For full lung inhales this tank is probably better than Apex tank that comes with the standard Cool Fire IV since it puts out a great deal of clouds but the Apex does have far more flexibility. Regardless of which is arguably better the tank does nicely match up colour wise with the Storm Edition model and looks great!


I loved the Cool Fire IV Plus when I reviewed it and I thought it was a superb device. The Cool Fire IV Plus Storm Edition hasn’t changed my opinion and I really do approve of the new Galactic Empire finish but that isn’t surprising since I am a Star Wars fan!

If you don’t already own the Cool Fire IV Plus then the Storm Edition would be well worth picking up but do keep in mind the included tank while good is slightly less flexible than the Apex that comes with the standard Cool Fire IV Plus. However if you are something of a cloud chaser then the iSub G tank included with this version is probably more desirable.

However at the end of the day whichever Cool Fire IV Plus model you choose to pick up I don’t think you will be disappointed! Many thanks to Grey Haze who kindly sent this device to Planet of the Vapes for us to review and you can purchase it here.
