The Coolfire 4 can push up to 40W of power while the iSub tank is capable of firing sub-ohm resistances as low as 0.3Ω and storing up to 4ml of e-juice.
Innokin Coolfire 4 Box Mod
The CoolFire series just got a major upgrade with the introduction of the Innokin CoolFire IV box mod.
The most compact, intelligent and powerful vaporizer from Innokin to date, the CoolFire 4 is packed with advanced technologies and features for the perfect sub-ohm vaping.
Don't let its size fool you – the Innokin CoolFire IV vaporizer delivers where it matters. Enjoy adjustable output from 3 to 7 volts or 6 to 40 watts. With a 14.5 amp limit, the CoolFire 4 is capable of firing atomizer resistances as low as 0.2Ω.
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 which means no power is wasted while you vape on your preferred output.
Compared to other box mods, the CoolFire IV is super sleek with a high-quality feel. The shell is beautifully crafted from aluminum and zinc, making it one of the most lightweight, durable, and comfortable mods around. It fits right in the palm of your hand with a convenient on/off switch located at the base.
The high-quality OLED screen clearly displays the resistance of the attached tank and coil, voltage, wattage, and remaining battery charge.
A stainless steel threaded spring loaded 510 connector ensures a reliable connection with most sub-ohm atomizers on the market. An eGo adapter is included in the kit for more versatility.
Unlike the other Innokin devices, the CoolFire 4 has a built-in 2000mAh battery and offers a USB port for charging and pass-through functionality.
