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.

  1. Typical quality from Innokin

    Review by edmnottm (Posted on March 16, 2017)

    Good piece of kit. Good feel in the hand and great to have a separate battery. Menu is easy to navigate and battery change is simple and quick.
    Sub V tank has quick top fill and gives out a good flavour and vapour. Have used the 316SS coil which operates well in TC mode and also has a good life.
    Overall, very pleased. Vape Choice delivered quickly and at a fair price.

  2. Coolfire TC 75w 18650

    Review by Pierssy (Posted on February 09, 2017)

    Nice mod, looks and feels good. Wish it had a full silicone cover as the fire button sticks out meaning it is best to switch it off in the pocket. I am new to temp control so, so far I have been using it in watt mode. It get through the battery a bit faster than my old Sigeli 30w mini but not by much. Altogether nice unit.

  3. So good I bought two!!!!

    Excellent product for wide range of vaping tastes.
    Large silky clouds. Only negative point is that you can't recharge the battery in the handset.
