Full Description


The Innokin CoolFire IV was a good little APV but it has been replaced with the newer Innokin CoolFire IV Plus which we are currently testing to make sure it meets our quality standards before offering it to our community. Our sincere condolences,

At VS we believe the new Innokin CoolFire IV is a big deal. It has all the features and characteristics to become the new king of its category. The new Innokin CoolFire IV overall build quality and robustness is obvious from the start. But the Innokin CoolFire IV is also extremely well designed and elegant. It is because of both its good look and its very solid build quality that we believe the new Innokin CoolFire IV will become one of the best APV of 2015.

The CoolFire IV is the newest and most compact, intelligent and powerful vaporizer from Innokin Technology. The teams of expert engineers and designers at Innokin have packed the CoolFire IV with the most advanced integrated vaping technologies to create the perfect compact Sub Ohm vaporizer. With 40W of vaping power, the CoolFire IV fires a full range of tank resistances and each is made with the highest quality materials to create a vaporizer that you can rely on! The compact power, bright OLED display, long lasting battery capacity and easy to use menu system makes the Innokin CoolFire IV the ultimate compact vaporizer for 2015.

The Innokin CoolFire IV comes in many vibrant and lasting finishes:

  • Black - Silver - Red - Blue - Amethyst - Purple - Gold - Green

Pretty Cool
I bought the purple one for myself, then I bought the gold one for my daughter-in-law, then I bought the silver one for my son, then I bought the red one for my daughter.  We all love them.  The read-out is bright and clear, user friendly, adjustable. So far the battery hasn't run down, but I charge it every night.  I like the charge port in the front rather than on the bottom so I can stand it upright while charging.  With anything, it takes a little bit to get used to the difference from what we were using, but quickly get attached.  It is kind of heavy, but that is because of the powerful battery.  It fits in the hand good and I have small hands.  It is all I use now and it goes wherever I go. I also bought the Innokin iSubG tank to go with it and am also very happy with that.

A tidbit about Innokins CoolFire IV
The tid: I own four in black, silver, gold and one CoolFire IV Plus 70W in silver. This mini mod stands up to rigorous critique. More developed than the CoolFire I, II, and III, the IV is destined to become a classic. Innokin subjects their products to rigorus tests before releasing these products to the public. You are getting more value for the cost, and products that hold up well. I bought these because I know if  I ever have a problem with any of their products I will get the service I would offer to anyone purchasing my own products. Excellent!

The bit: Although their products are designed and manufactured top notch, The CoolFire IV would be a bit better if you could swap out batteries or at least a battery that was above 2500 mAh at 20 Amps or above. Possibly a bigger LED screen. I like the new 2016 mods with upgradeable firmware. This would make them fly off the shelves even faster than they allready have been.
All in all, The CoolFire IV is a great transition mod or just perfect for those who like a nice simple amount of vape. when sub ohming the battery tends to drain a bit fast. My remedy for this is rebuilding my tanks upwards around 1.5 ohms minimum, with my settings around
3.6V to 4.8Volts. This gives me a rather dense yet cool draw from my tanks. I'm just not into hot vaping.
Beyond all this I will definately recommend to everyone the Innokin CoolFire IV is a great addition to anyones collection.
Hopes this helps.

This is my first box mod, and I"m really happy with it. Paired with my Nautilus tank, this is the vape experience I was going after.  I set the unit to 10.5 watts with a 1.6 ohm coil, and am really pleased with the flavor and vapor production. I have to mention that it feels great in either of my hands...I love the strong-feeling weight and size of it, and the easy operation. the blue color ROCKS . Nice touch with the lanyard attachment... mine fit right on. Great service from WOV, of course, as they shipped everything right out asap. I'll definitely be after a model with removable batteries for sure now...lol... but I'm grabbing a couple more of these also...they are awesome. Battery life is pretty goo too.( been vaping on it medium heavy now for about 9 hours and the light is still yellow...not bad.) Perfect entry-level "nothing to sneeze at" mid-power box mod.

Best place to buy your vaping products, especially if you want the real authentic product. No need to worry when ordering from worldofvape. Thank You..
I love my coolfire IV. The customer service was wonderful in helping me pick out the right one for me. I will only order from worldofvape. They helped me choose the Nautilus tank also. Love them both.

Loving it!
I bought one of these for my boyfriend a couple months back and finally got one for myself.  He loves his and now I love mine, too.  It fires great, has long battery life, and the overall feel of the device  is perfect.

Love the feel of this.  It's not too heavy. Fits well in my hand.  And most of all, it works fantastically.  I use it with both the Atlantis and the nautilus mini.

Great Mod
Works rater well with my Aspire Atlantis. I can't seem to put it down. It also seems to have that elusive cool factor. I chose the green one and I'm not disappointed.
