The Innokin Cool Fire IV is the latest addition to the cool fire range realised by Innokin. This compact little box mod is Innokins most compact, intelligent and most powerful (40w power & 2000 mAh) device in the series and is visually very impressive sub ohm vaporizer. The coolfire IV exudes style and finesse with its look and feel, incorporating a bright OLED display, easy to use menu system and long lasting battery. The device fits snuggly in your palm of your hand and is only just larger than the Eleaf iStick 30w.

The Coolfire IV extends its features from its predecessors, with variable voltage and variable wattage features. The Coolfire IV now has 40w power and uses a 2000 mAh polymer Li-Ion battery but now has variable voltage capacity from 3.0v to 7.5v and now has adjustable variable wattage 6.0w to 40.0w. The system has an inbuilt battery level indicator and also remembers your last used voltage or wattage used. The device can also be used whilst being charging and utilises a spring loaded positive pin connection. Vrms DC ensures greater accuracy when adjusting wattage or voltage.

As per most batteries made by Innokin they include the latest safety technology such as 15-second auto cut off mechanism, 3 click safety system, over discharge protection, atomizer short circuit protection, and charging short circuit protection. The low voltage indicator works by flashes on LED and battery bar when battery is lower than 3.3v causing automatic shut down. The Innokin Cool Fire IV is compatible all 510 and eGo fitting devices and is available in black, blue, purple, red, amethyst, steel colour.
