The Cool Fire IV has a flush 510 connection with a spring-loaded positive pin,
durable stainless steel threading, an included eGo adapter.
The Cool Fire IV has a variable voltage range of 3.0~7.5 voltages adjustable in 0.1 volt increments and a variable wattage range of 6.0~40.0 Wattages, adjustable in 0.5 watts increments.
The Cool Fire IV uses Vrms DC current and is very accurate with a power deviation of 0.1 Wattage. The full 40 Wattages is precisely maintained between resistances of 0.3 to 2.5 Ohms. There is no wasted power and exact accuracy means you are always the power level that you choose. Vrms provides superior precision in delivering the exact wattage Ohm's Law requires and stable power means better .
The high quality OLED screen looks great and clearly displays the resistance of the attached tank & coil, voltage, wattage and also accurately shows the remaining battery charge.
