The Innokin Coolfire 4 Plus is an upgraded version of the Coolfire 4. The upgraded version increases the wattage from 40 to 70 W and the minimum resistance from 0.3 to 0.1 for the coil heads. Plus it is compatible with other tank systems for versatility in vaping.

Innokin Coolfire 4 Plus + Testing and Performance

I spent a week with this device and tank trying it out and I actually like it. I didn’t think I would at first, but the more I used it the better the vaping experience became. I normally like to run my wattage between 40 – 60 watts for .5 to .8 ohm coils but the iSub coil heads at 35W worked perfectly for me. I got good vapor production and great flavor from the tank with the airflow open ½ way.

Build quality and Design

I really like the ergonomic design of this mod. The rounded corners are more comfortable for holding and it slides easily into my pocket for quick trips to the store.

Durability

It feels very sturdy and durable. It is lightweight and feels good in your hand. I have not had any accidents ( by dropping) so I haven’t really been able to see if it resists scratches or dings. But just with everyday usage, I have not incurred any. It looks and feels like a well-made product.

Ease of Use

The Innokin Coolfire 4 Plus is very easy to use and I like the simplicity of the device. The menu system is also very simple for those who don’t want to scroll through to find out how to change their wattage. This would be perfect for someone who wants to step up to a mod but does not want all the complicated menus and features of some other higher-wattage mods.

Ergonomics

This mod is perfectly suited for your hand. The corners are rounded and it tapers in to allow for a comfortable grip. The buttons on the side are smooth and easy to press with your finger or thumb, depending on which way you turn it.

 

Features and functions

When you hit the fire button the battery indicator light flashes green, yellow or red depending on the charge left in the battery. I like this feature because it tells me immediately if my battery is getting low without having to look at the screen display. I also like that I can flip the screen around and a big plus is the ability to vape while charging (pass-through mode). I never have to worry about leaving for the day without a full charge because I can charge and vape on the go.

 

Wattage and Power

The integrated battery and chipsets deliver a maximum of 70 W. If you don’t vape in the higher wattages this would work well for you. The coil heads that come with the Apex iSub tank are .5 and are rated for 25 – 35 W, but you can use other tanks with the mod as well.

 

Battery Life

Battery life for this device is good when using the coil heads that come with it. If you’re using another tank with different coils you may need to charge more than once per day, depending on the wattage you’re using. At 35 W this battery lasts me all day, but if I switch out for another tank I find it drains the battery quicker because I’m using a higher wattage (to be expected).

 

What We Liked

+ Top-fill system
+ Tank is leak-proof
+ USB port is on the front
+ Easy menu navigation
+ Includes an extra coil head
+ Pass-through charging capabilities
+ Easy to change coil heads ( no draining tank first)

What We Didn’t

Tanks have a bit of a gap on top
Fill holes instead of wider slots
Can’t see when the tank is full
Cannot disassemble tank to clean

Value

This mod kit is priced between $55 and $65 through most online retailers. This mod does not have a temperature control so some people may think that the price is high for not having a TC mode. Personally, I don’t need TC mode because I prefer using wattage mode so it is not a dealbreaker for me. To me, $55 is a good price for a mod with a tank that works well.

Final Verdict

I really like this mod and think it would be great for vapers wanting to move up to sub-ohm vaping because the coil heads are rated for 25 – 35 watts and at that rate the draw is smooth and easy with good airflow and vapor production. Also it is priced similar to other mods in the same category. Not having temperature control is not a drawback if you don’t use it. I recommend getting one if you’re curious about trying out a moderate wattage device.
