Cool Fire IV 40 Box Mod - By Innokin
The Coolfire 4 is the newest in the line of internationally bestselling Coolfire vaporizers. This new version is super sleek with an ultra high quality look and feel. It is one of the most beautifully designed mods we've ever had the pleasure of trying. It fits right in the palm of your hand just slightly larger than an iStick 30W. We especially like the on/off switch at the base of the Coolfire 4.
The Innokin Coolfire 4 features a greater range of variable voltage, variable wattage, advanced safety features, portable electronics charging and also "vape while charging technology. The Coolfire 4 has a flush 510 connection with a spring loaded positive pin, durable stainless steel threading, and an included ego adapter. The Innokin Coolfire 4 has a variable voltage range of 3.0v to 7.5v in 0.1 volt increments and a variable wattage range of 6.0w to 40.0w 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.
