Our Take

This is one of the best vape mods for those wanting exceptional performance combined with ease of use. The iSub Apex Tank turns this device into a pretty extreme vape. It is a straight forward device that hides complex technology within an easy to use user interface that competes exceptionally well against our #3 Kanger Topbox Nano Mini

Cons

It is difficult to fault the Innokin Cool Fire IV but there are a number of variants out there, the 70W device combined with the iSub Apex tank is the one to go for. BUT if you just want a simple device to quit smoking then there are simpler smaller e-cigarettes HERE that may well suit you better

The Cool Fire IV has also been upgraded to the higher 75 Watt Innokin iTaste Kroma A

The Innokin iTaste Kroma-A is similar in specification to the Cool Fire IV but has been upgraded with more power and a slightly more modern sophisticated design and new components. The Kroma-A functionality and operation are very similar to the Cool Fire and has an additional 5 Watts of power. Having said all that we still prefer the Cool Fire 4 Plus simply because it is a classic, a true vape-master.

A durable, solid box mod unit for vapers who demand extra vapour

The variable wattage or temperature control models makes the Innokin Cool Fire IV kit the perfect choice for new vapers starting out or more advanced vapers. Even for more seasoned vapers, the ability to change the wattage depending on your coil hardware or your vape preference, mouth to lung or direct inhale is a real asset for the Innokin Cool Fire.

Similar to the #3 Kangertech Topbox Nano the Innokin Cool Fire 4 is a brilliant vape mod with everything you’ll need right in the box

The Innokin Cool Fire IV Plus 70W iSub Apex comes with everything you’ll need to get started right in the package. It’s ergonomic design fits right in the palm of your hand meaning you’ll feel comfortable vaping whenever you want to. Make sure you get the iSub Apex Tank option and don’t confuse it with the cheaper and lower spec Isub G Version or the Cool Fire 40W version.

You can even vape whilst you charge! Priced at around £50.00-£60.00 the Cool Fire is worth the money. We have found authentic Cool Fire IV’s here as low as £49.99 here so get yourself a bargain.

And buyer beware, there are a lot of fakes around.

You can vape with the Innokin Cool Fire Plus even whilst it is charging due to its unique ‘pass through’ technology. Plug in the micro USB to any port and continue to vape whilst your e cig is charging. Charging this mod is a doddle, with a full charging lasting at least 24 hours for one of our heavier vapers. This mod is also great for all levels of users. Beginners, intermediates and advanced vapers will all benefit from this mod as it reaches 70w and can be used with 0.1 ohm coils – the lower spec Cool Fire 40w is perfect for beginners.
