Like its predecessor TC100, Cool Fire 4 75W TC uses the ultra-fast and accurate AETHON temperature control board to give you that precise control. This kit features variable Temperature Control with a maximum of 75W output to power your favourite Titanium, Ni200 or stainless steel coils.

If you are thinking of moving from intermediate to advanced vaping then this kit is a good investment. With TC and Sub-Ohm capabilities together with the 18650 batteries, this kit will give you style with power.

Remember the kit also ships with Innokin’s latest iSub V tank. With its large 3ml capacity, you’ll be able to enjoy more vapour and better flavour throughout the day.
