The Innokin Cool Fire IV ISub Kit is a front-runner as being one of the most compact and powerful vaporizer starter kits to date from this company. This e-cig box mod is made with advanced features, perfect for sub-ohm vaping. It can be adjusted from 3-7 volts or 6-40 watts, which is an ample amount for most sub-ohm tanks available on the vaping market today.  

The Cool Fire 4 ecig mod comes built with a 14.5 amp limit, being capable of activating atom resistances down to 0.2 ohms. The Cool Fire 4 uses a  DC for a higher increase of accuracy with a DC deviation of 0.1 watts. The 40 watts this piece comes with is maintained between 0.3 to 2.5 ohm's, meaning there is no power wasted while you vape using your preferred output settings.

This device is one of the most durable with its construction of zinc and aluminum for its price. This vape mod is rated as one of the most user-friendly ecig mods out along with the design, making it easy to use and fit in any size hands. It has easy functionality with the on/off switch located at the bottom of the base for easy access. Other features include OLED screen, a stainless steel threaded spring-loaded 510 center pin. It has a built-in 2000mAh battery that offers a USB port for charging and quick-lite functionality.

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
