Innokin Cool Fire 4 TC 18650 iSub V Kit

The Innokin Cool Fire 4 TC 18650 iSub V Kit is a single 18650 battery (sold separately) powered platform that takes Innokin’s powerful chipset and pairs it with the Innokin iSub V Vortex Sub-Ohm Tank. The Aethon Chipset has a maximum 75 watt output and comes with UltraFast firing technology that reduces firing time to just 0.2 seconds after activation. Also included is ClearWave Noise Cancellation to create the best output curve, and Precision Coil Resistance Reading that reads resistance to the nearest hundred-thousandth of an ohm. The temperature control system includes the RampUp PreBoost feature to control power output before reaching the wanted temperature, therefore increasing customization of the experience.

The temperature control feature supports the Stainless Steel, Titanium, and Ni200 Nickel heating elements. The included battery bay makes battery loading very easy and quick, increasing flexibility with the device. The iSub V Vortex TC that’s included with the Cool Fire IV 75W has a 22mm platform and aims to create a very good experience for its price point. The 3mL capacity allows the user to vape juices for a large amount of time before needing a refill. The Innokin Cool Fire 4 TC 18650 iSub V Kit has the perfect amount of power and features for its reduced price.
