About the Innokin Cool 4 TC 100w Starter Kit

Cool Fire is a name that Innokin has become famous for and this fourth generation sets a new standard in high quality vaping. The Cool Fire 4 has a long-lasting internal battery with 3300mAh power and it is one of the top line vaping systems, designed to ensure powerful and effective functionality all day long. The manufacturers suggest that a fully charged battery should last a whole day of light to moderate vaping.

In terms of design, Innokin has made sure this elegant mod does not disappoint. It can be enjoyed in a choice of four different colours and is ergonomically curved for a comfortable fit into the hand. The power button is well positioned for easy one-handed use and it provides a pleasurable experience as you vape. The large screen is OLED which ensures it is bright and easy to read.

The latest technologies have been included to ensure it delivers a premium experience. It incorporates Temperature Control which is one of the newest innovations in the industry. Temperature Control is included in devices which use coils made from Nickel, Titanium or Stainless Steel and this has a higher resistance when heated, allowing for accuracy in detecting temperature. This accuracy means the vaper can set the temperature for each coil and this can help ward off the painful and nasty throat hit that comes from burned flavours.

It can also be enjoyed in standard mode, if preferred. Innokin also incorporate their well-known and highly effective ‘vape while charging’ in the Cool Fire range, making it even more convenient and enjoyable to use.

This starter kit also comes complete with the iSub VE Tank. With its easy top-fill design and strong Pyrex construction, the iSub VE can be used for both standard and sub-ohm vaping. It fits with ease with the Cool Fire IV and has a 2ml e-liquid capacity. 

The Cool Fire name carries a legacy of durability, reliability and power, and Innokin has no intention of straying from this path with the Cool Fire IV TC 100w. The Cool Fire IV Plus can output up to 100 watts of power and features temperature control support for Ni200, titanium and stainless steel wire. For those that prefer the manual wattage mode for use with standard Kanthal coils, this is of course present.

Rather than utilising removable batteries, the Cool Fire IV TC 100w features a built-in 3300mAh battery which is charged via micro-USB and will last around a day of light-to-moderate vaping. Once you have run out of charge, fear not, the Cool Fire IV features fast 2 amp charging, meaning you can get a full charge in under 2 hours (when using a suitable charger) - on top of that, you can even vape while the box mod is charging!

A great tank and a top-of-the-line box mod, the Innokin Cool Fire IV TC 100 kit is a complete vaping experience that offers the performance and reliability that Innokin is famous for.

What is Temperature Control?

Temperature control (often abbreviated as 'TC') is the latest innovation in electronic cigarettes which helps you to avoid those unpleasant, burnt-tasting dry hits and produce the purest flavour from your e-liquid. Temperature control enabled devices utilise coils made from Nickel (Ni200), Titanium or Stainless Steel (Innokin Cortex is compatible with Ni200 and Titanium wire for temperature control) as opposed to standard Kanthal.

Ni200, Titanium and Stainless Steel wires change resistance when heated, allowing a device to detect the current temperature - this means you can set a temperature that the coil will not exceed. To use temperature control you will need a coil head or RBA build equipped with one of the aforementioned wire materials.

How do I fill a 'top fill' clearomizer?

To fill a 'top fill' clearomizer with e-liquid, simply unscrew the mouthpiece at the top, now tilt the unit to a 45% angle and pour the e-liquid into the barrel against the inside wall of the clearomizer. The aim is the coat the inside wall with e-liquid. Avoid getting it down the central metal barrel (aka the breathing or central pipe) as this may cause it to leak.  Do NOT over fill your clearomizer.


What is Sub Ohm vaping?

Sub ohm simply means the resistance of the atomizer coil is below 1.0 ohm. Sub ohm coils are generally larger and therefore can utilise more power and cover a greater area of wick - a combination which results is massive vapour production. A high-powered device paired is required for sub ohm vaping (a separate high-drain battery may be required - e.g. the Samsung 25R 18650).

"Direct-to-lung" is the suggested vaping style for sub ohm devices (as opposed to "mouth-to-lung" -  how a traditional cigarette would be smoked).

High VG E-Liquid is recommended when using sub ohm devices.


What is the warranty on this product?

This product comes with a 90 day warranty from the date of order. However, this does not cover misuse, damage or standard wear and tear.
