A starter kit that is highly appealing, powerful and can reach sub-ohm territory, you’re in for a great experience this offering. Let us introduce the Cool Fire iSub Starter Kit by Innokin Technology. If you keep up with the market, you’ll know that Innokin has produced some of the most legendary mods within the vaping market, including the industry known iTaste MVP Series. This manufacturer produces only quality made mods that withstand the test of time, and we’re not doubting Innokin’s latest work of art, the Cool Fire 4 iSub Starter Kit, not for one minute.

The Cool Fire 4 stems from the Cool Fire Series, which is a popular line of regulated mods made by Innokin Technology. The Cool Fire 4 looks brilliantly pleasing, sporting curves and beautiful colors. The Cool Fire 4 adopts the box mod shape this time around, a design that has become most favored amongst consumers. It is not one of the most compact, intelligent and powerful vaporizer to date from Innokin. This mod has been designed with advanced features, perfect for sub-ohm vaping. It has the ability to be adjusted from 3 to 7 volts or 6 to 40 watts, which is an ample amount for most sub-ohm tanks available on the vaping market. The Cool Fire 4 has a 14.5 amp limit, so it is capable of firing atomizer resistances as low as 0.2 ohm. The Cool Fire 4 utilizes Vrms DC current for increased accuracy with a power deviation of 0.1 watt. The full 40 watts that this little beast comes with is precisely maintained between 0.3 to 2.5 ohm’s, meaning that no power is wasted while you vape on your preferred output.

If you’re looking for a device that is sleek and has a high-quality feel, you’ll adore the Cool Fire 4. This device is absolutely stunning, and has been constructed of aluminum and zinc, giving it that lightweight, comfortable and durable feel you’ve been seeking. The Cool Fire 4 also plays quite nicely with being a user-friendly mod, and Innokin has made sure of it by making it to fit comfortably in your hand with the convenience to turn it on and off by simply flipping a switch that’s located on the base of the device. Other features include a brightly lit OLED screen, a stainless steel threaded spring-loaded 510 center pin, and to power this bad boy, it has a built-in 2000mAh battery that offers a USB port for charging and pass-through functionality.

To turn the Cool Fire 4 into a starter kit, the iSub Tank completes the package. The Innokin iSub Tank is a top quality, yet affordable sub-ohm tank. It’s constructed of stainless steel and utilizes Germade made P.C. for its tank portion. It has a 4mL e-liquid capacity and also uses Japanese Organic Cotton for its wicking. The iSub Tank uses a 0.5 ohm coil and has a no-spill coil swap system feature. You’ll also enjoy the iSub Tank because of its permanently attached mouthpiece, which has a wide bore, and its 12mm adjustable airflow slots, which allows you to produce an outstanding vapor production, while maintaining a solid flavor production.

Great Value

Wish these were in stock. I would buy more as spares. I just bought the Cool Fire IV locally because I had to replace my possessed ELeaf which was getting ready to explode, I actually had to take it apart to stop it from turning on.
I use this with my UWELL tanks, the only thing I wish is that the battery life compared to the RIP ELeaf.
It functions as it should and I can get a day of vaping on 1 charge. Good thing is you can charge and vape.
Good product with a great price. 3/19/2016
