The backside of the device says that the minimum resistance is 0.3ohm, but the guide says that the Coolfire IV can fire down to 0.2ohm. We testified and our Coolfire IV did fire down to 0.2ohm.
The battery lifetime is great on the Coolfire IV being a 2000mAh battery. The Coolfire IV will provide you with good vaping on a 0.5ohm coil throughout the day. Higher resistance builds and more modest vaping will signify that the battery should endure several days. The battery capacity for the size of the mod is great. It is possible to charge the battery by means of the USB pass through charger and you will need several hours to totally charge.
The Innokin Coolfire IV works from 6-40W, which is quite respectable. The Coolfire IV is focused on those who like to vape at lower wattages.
Power Button Colors
The Coolfire IV start button will show different colors depending on the battery service life remaining. Green indicates practically completely charged, yellow half power and red means low battery life.
It practically doesn’t seem like a box mod due to its handy design and smooth curves. Nevertheless, because of its modern design, it seems lot smaller and certainly is like a much higher quality unit rather than plasticky iStick 50W.
This is one of the major advantages of this mini box mod. The brushed aluminum texture on the exterior is great and of high quality.
Spring Loaded Pin
The Coolfire IV includes a good spring loaded pin, which indicates all of your tanks will fit excellent and flush onto the unit. The threading is stainless steel and is buttery smooth when affixing a tank onto it. The Coolfire IV kit also includes an ego adapter, which is a fine touch for those who want to use an ego style clearomizer.

Innokin have created several infamously expensive items previously, but the Coolfire IV is a great offer at about $40. You won’t buy this quality type device for this price from another brand.
The screen could be a bit larger, as presently it is very small.
The 2000mAh battery on the Coolfire IV wasn’t actually a positive or negative. The company should develop a battery with a bigger battery capacity. It may seem like it is possible to remove the battery, looking at the bottom of the unit, however it is actually non removable. It will be better to have a removable battery on this gadget as somebody likes charging in proper chargers.
We completely enjoyed the Coolfire IV and its stunning appearance and quality build. I think at least the Coolfire brand has definitely deserves its name and created a truly ‘cool’ looking gadget. The brushed aluminium finish feels great and the gadget sits properly in your hand. It would be better to develop a removable battery in the Coolfire and a bit larger screen, but besides that there isn’t anything to make a complaint about with this unit in the least. The Coolfire IV device will be a great purchase for about $40. It is an excellent box mod for beginning vapers and also those who want to use the full 40Ws and firing down to the lower resistances.
If you are searching for a 30-40W gadget, then do not think twice and buy Coolfire IV as it is one of the best 15 vaping devices in 2017.
