Innokin Cool Fire IV TC100W iSub V Kit Review | Vape Kit

Innokin-Cool-Fire-IV-TC100-iSub-V-Kit-16Innokin products have always felt like the time invested in design & execution are well considered.

Certainly, Innokin isn’t the only manufacturer who ships well thought out products, but whenever I use a Innokin product, I recognize that there’s more to it than just a bump up in wattage.

There have been talks of the new and innovative Innokin Cool Fire 4 TC100W mod for several months with their own Aethon chip set. And Well, it’s finally here.

The TC100W is the newest version of the highly popular Cool Fire 4 mod from Innokin which currently offers power of up to 100W and has both Temperature Control and Variable Wattage functionality.

Read this Innokin Cool Fire IV TC100W iSub V Kit review to find out more about this product.

Feature Highlights

Design & Build Quality

Innokin have used the same body as with the Innokin Cool Fire 4 Plus, for those familiar with it, albeit with some somewhat different design accents.

Smooth and curved to perfectly fit into your hand, and with an ergonomically-placed power button, the TC100W is a true pleasure to vape.

The Cool Fire IV TC 100W is compact, powerful, durable, gorgeous and more, and sets the new standard in vaping excellence.

Innokin iSub V – VortexTank

The new iSub V is the flag-ship tank for Innokin.

This latest tank from the iSub tank range holds 3mL of e-liquid in a glass tank.

This tank is made from stainless steel & features the usual airflow slots (2) and removable drip tip. The Express kit only comes with the mod.

The design of the top fill and chimney is different. However, not all TC 100W kits have the tank included so be sure to check.


Powered by the new Aethon chipset from Innokin with 100W of pure power featuring Clearwave noise cancellation technology, the device supports Nickel200, Stainless Steel and Titanium in Temperature Control mode.

The chipset promises ultrafast and accurate performance to 0.00000 ohms, according to Innokin.

You’ll no longer experience consistent heating and dry hits, while standby power usage is minimal.

This is also a Temperature Control chip, so vapers are able to use the Innokin Cool Fire IV as a temperature-control & variable wattage device at higher-levels than before.

Long-lasting Power

With a long-lasting internal 3300mAh integrated battery, the Cool Fire 4 TC100W is designed as one of the top of the line’ compact vapes.

If you are an average vaper who vapes infrequently, this battery should last you all day.

Innokin’s new Aethon powered unit possesses 2 Ampere charging which is quite fast and reliable and takes about 3 to 4 hours, though you can vape while still charging if you need to.

Plugging a cable between a USB charger and the USB port is not hard when you’re sleeping, but do not forget to plug in. It also features advanced safety protections against over-charging.

The Cool Fire IV TC100W has a flush 510-connection with a spring-loaded gold plated positive pin & durable stainless steel threading.

OLED Screen

A Cool Fire IV 100W-TC depicts the levels one chooses and power levels in real-time.

The display shows volts, watts, battery power, resistance, and temperature.

Operated via 3 durable buttons including the trademark Cool Fire IV over-sized fire button with its large, bright OLED screen on- the base, the TC100W is easy to use, stylish & powerful.

This is where vapers find their menu options and the LED light helps you keep note of the charge of the battery.

Beauty of the Box

The Coolfire 4 line was never box shaped and Innokin never lacks style with this more powerful version.

This product comes in 4 colors: red, black, white, or blue, and boasts a similar sheen to the Kanger KBOX.

What’s in the box?

  1. Innokin Cool Fire IV TC100 Mod device
  2. Innokin iSub-V Sub Ohm Tank (Not included in the Express Kit)
  3. Pre-installed iSub 0.5-ohm atomizer head

  7. Tank band
  8. Spare drip tip
  9. Micro USB Charging cable

From its top class features, I’m pretty sure you should be expecting a number of advantages and benefits of the Cool Fire IV. The following are some of the things which make this vaporizer a cut above the rest.

  • Excellent Build Quality
  • Ultra fast response
  • Great precision in coil resistance readings
  • Easily portable courtesy of its portable design
  • The temp control mode works well with Ti, Ni, and SS
  • Durable -100% stainless steel
  • Added Power up to 100W
  • Low noise operation
  • Detachable delrin drip tip
  • Replaceable tank
  • Adjustable airflow
  • Maximum control over flavor and vapor


  • The only concern with regards to this vaporizer is its high price tag
  • Also the 3300 mAh battery life might not be great for vapers frequently vaping at the top-end of the 100W power capacity range.


The Cool Fire IV TC100W iSub V kit is another superb device from Innokin. Its Aethon chipset is excellent and it supports all common types of wires.

The iSub V is a rather affordable flavor tank which is easy to use and offers great flavor and ample vapor. At only $15 a pop it’s definitely worth buying.

The Cool Fire 4 TC100 has it all across the coil mediums when it comes to performance.

It’s a welcome sight to get to see stainless-steel working a treat in temperature control mode.

The device pretty much works without issue in Temperature Control and now provides 100W power compared to the preceding CoolFire IV’s 70W limit.

The only slight negative I can find and it’s not an actual flaw with this device is that the capacity won’t be sufficient for heavy vapers who enjoy cloud chasing at high Wattages though for everybody else, this is a remarkable device and well worth picking up!
