Innokin Cool Fire 4 (IV) 40W Mod

Genuine Cool Fire IV. The sleek Cool Fire 4 is the newest in a line of bestselling vaporizers and it fits in the palm of your hand (not much bigger than an iStick 30W).

This box mod can be used with most clearomizers and atomisers by Innokin and is a perfect partner with the standard iSub tanks, but it's also compatible with those by other brands.

The price is for the Cool Fire IV only. It does not come with a tank device or liquid.

The box comes with a scratch panel so you can verify the authenticity of your product on the manufacturer's website.

Not recommended for inexperienced users. Rated as user level 3 of 5. Please check your level before purchase if you're not sure.
