Packed with 70Watts of precise output that can fire down to 0.1 Ohm and a long lasting real 3300mAh battery, the CoolFire IV Plus is designed to be the top of the line compact all day vape. Curved to fit perfectly into your hand, with an ergonomically placed power button, this new Innokin is a true pleasure to vape. The CoolFire IV Plus is easy to charge via microUSB.
The Plus model features quick charge function (via 2amp charger sold separately) and has proven on-board advanced safety features including overheat and over-discharge protections.
The ISUB G Kit comes with the updated iSUB Tank, which as rthe name suggests, is capabale of sub-ohm vaping thanks to the Japanese cotton coils firing as low as 0.2 ohm. Replacement coils for the G tank are available in 0.2, 0.5 and 2 ohm covering all vaping needs. The sturdy pyrex tank has an upgraded capacity of 3.8ml increasing the times between refills.
A great sub-ohm kit, the Cool Fire IV Plus iSUB G is a great choice.
