Innokin Coolfire IV Plus Review

We take a look at the brand new Innokin Coolfire IV box mod. The Coolfire IV Plus is an upgraded version of the popular Innokin Coolfire IV mod. The new Coolfire IV Plus is marginally thicker and heavier than the original, but therefore boasts a larger battery capacity, higher max wattage and can fire down to a lower resistance. The Coolfire IV Plus has a nice 3300mAh battery vs the 2000mAh on the original. The Plus now has a max wattage of 70W, up from 40W on the original. Lastly you can now fire down to 0.1ohm on the Plus, whereas the original could only go down to 0.3ohm. In a market where higher power and lower resistances has become quite mainstream, the Coolfire IV Plus boasts some much needed improvements. The Coolfire IV Plus does not have temperature control, so if you are looking for that, you will need to look at Innokin’s new Cortex mod instead.

At the time of writing the Coolfire IV Plus only comes as part of a kit, either with the Innokin Apex or the iSub G sub ohm tank.

Thanks to George over at Innokin for sending over the device to review.

It seems Innokin have taken a leaf out of Kanger’s book when it comes to packaging. The new Coolfire IV Plus packaging is really nicely designed and comes labelled with all the info you might need to know at a glance. The packaging also features a scratch and check for checking the authenticity of your mod.

I mentioned above in the intro that the Plus comes with several improvements over the original. The Plus boasts a higher max wattage, lower minimum resistance and a better battery life. The Plus also comes with a much larger, clearer OLED screen. The small screen was one our our few complaints on the original Coolfire IV and it is good to see Innokin have improved it alongside upgrading a host of other features.

The original Coolfire IV was a pretty sleek looking device. Whilst the new Coolfire Plus is slightly chubbier than the original, Innokin have managed to somehow make it look even sleeker. The one we have in Black, looks really nice and it sits really nicely in the hand whilst vaping.

The brushed Aluminium finish on the Coolfire IV Plus feels really solid. The whole mod is made very well and it feels like a top quality device, as we have come to expect from Innokin. The buttons are much improved on the plus as the ones on the original felt somewhat plasticky. This is no longer the case and there is no button rattling either. The threading on the 510 connection is made very well and you can feel that the threads are really solid. The 510 connection also comes with a nice spring loaded pin.

The Coolfire IV Plus does not feature temperature control, but I can still see it appealing to a lot of vapers who are looking for a mod in this wattage range. It is a great looking and well built box mod and I can see it being very popular with beginner to intermediate type vapers.

I can’t really find anything to dislike about this mod. It is a bit pricier compared with competing mods in the same category, like the Eleaf iStick 60W and Joyetech Evic VTC Mini. However, the Innokin devices have always been associated with quality and that certainly comes across with this device. I’d be happy to pay that bit more knowing I am getting a quality device that will last a long time.

Personally I prefer a removable 18650 battery in my mod, so I can switch batteries when one is drained. That would be the one improvement I would want on this mod for my personal taste. However, I know a lot of vapers who don’t want to worry about switching batteries and the Coolfire IV Plus does have passthrough charging.

The Coolfire IV Plus is a fantastic 70W no thrills box mod. It looks fantastic, is built well, has a good battery life, is very ergonomic and does what it is meant to – vape. For those looking for a well made box mod in this wattage range and who are not fussed about temperature control, then the Coolfire IV Plus is a fantastic option. If you want something similar with temp control, then wait for the Innokin Cortex or take a look at the Evic VTC Mini or iStick 60W.

I’d recommend the Innokin Coolfire IV to those looking for their first box mod who don’t want to worry about batteries and temperature control, or those just looking for a reliable, sleek 70W box mod with a solid battery life.
