Innokin CoolFire 4 ReviewPin

Innokin is BACK with a brand new CoolFire 4 vape and its bloody fantastic

Innokin are true pioneers with their technical innovation and environmentally friendly electronic cigarettes. Always pushing the boundaries with what’s possible, it is no wonder then that the company is one of the most visible brands in the world of vaping. In this respect, they’re very much like Samsung in the mobile space — big and very popular with consumers across the board.

Innokin has four major brands: the iTaste, iClear, CoolFire and the latest addition to the fold, Lily. Here we’ll be taking a closer look at the Innokin CoolFire 4, which has been receiving A LOT of praise recently, in order to find out if all this hype is justified.

Let’s do this.

Innokin CoolFire 4 Review: Design

The CoolFire 4 has a completely different design to its predecessor. It’s less bulky, more stylish and has a great appearance. Its plain design is smart and makes it a versatile mod to have. The CoolFire logo is pressed into the bottom right corner in a great position that fits well with the design.


Innokin have completed revamped the design making it so much easier to hold and use. The buttons are easily accessible on the side, meaning you can switch things up or turn the device off without having to look and see what you’re doing.

  • Innokin CoolFire 4 Review: Performance

The CoolFire 4 is the perfect mod for a beginner vaper, it’s not too serious. But it does go all the way up to 40W, meaning you can get some pretty serious tanks — tanks like the Aspire Atlantis 2 — on top of it for some sub-ohm vaping action, if that’s your thang. In addition to this, the voltage runs from 3v to 7.5v, which fits perfectly with the 99.9% of tanks or glassomizers above the sub-ohm range.

Basically, this thing will run any type of tank — big or small.

Innokin CoolFire 4 Review: Battery

For moderate vapers, the Innokin CoolFire 4, with its 2000mAh battery, should be perfectly adequate, providing you remember to charge it once a night. For more hardcore vapers — i.e. guys and gals that chug all day long — it might not cut the mustard and leave you hanging later on in the day. If that sounds like you, you might want to check out THESE box-mods which all feature removable batteries.

As I said, though, this is a unit for the less experienced vaper. The CoolFire 4 delivers excellent performance and very decent flavour, as well as cloud production, for a very reasonable price of £39.99. This is a gateway mod, really, a device that can help you find your feet in the world of vaping before moving on to something more polished and professional (and costly).

Innokin CoolFire 4 Review: Verdict

For me, the Innokin CoolFire 4 is a breath of fresh air. It is a hugely enjoyable mod and provides one of the best vaping experiences I have ever had at this price range. The design is vastly superior to most of its peers, the features are simple and intuitive to use, and it pumps out clouds like nobody’s business once you’ve got the right tank on top. Therefore, if you are brand new to vaping, or just fancy upgrading your pen-vape to a mod, then the CoolFire 4 is EXACTLY what the doctor ordered.
