Get great style and performance with the Innokin Coolfire 4

The super sleek Coolfire 4 is the newest in the line of internationally bestselling Coolfire vape components. Only slightly larger than the eLeaf iStick 30 Watt, the Coolfire IV has a variable voltage range of 3.0v to 7.5v in 0.1 volt increments and a variable wattage range of 6W to 40W adjustable in 0.5 watt increments.

The Coolfire 4 uses VRMS DC current for increased accuracy with a power deviation of 0.1 watt.

The full 40 watts is precisely maintained between 0.3 to 2.5 ohms. There is no wasted power and exact accuracy means you are always vaping the power level that you choose.
