Innokin Cool Fire Ultra TC150 styling and build quality

The styling of the Coolfire Ultra TC150 is very attractive since the device has a really pleasant contoured design that makes for a very comfortable grip. There is some reasonable weight to the device but when held in the hand it seems nicely balanced. Unlike most devices this size it is actually rather thin which while feeling good in the hand does create a slight problem since it doesn’t allow a great deal of room for larger diameter atomizers so keep in mind that anything over 23mm is going to overhang.

Now this in itself is acceptable if it wasn’t for the bad positioning of the 510 pin. For some reason when you fit an atomizer to this device for the first time you never know if it will sit flush or not. The included Scion Tank sits flush but my Kennedy Trickster RDA had a very noticeable gap present. Now while you might be able to put up with it it does let things down a little but thankfully it has no effect when it comes to firing your atomizers. Do keep in mind it does look noticeably worse when fitting large tanks such as the Kayfun 5 or Uwell Crown III since they clearly lean to extent and immediately confirm to the user that the 510 pin is fitted at an awkward angle. It seems very sloppily down to me and given Innokin’s high standards I expected better but even though it is highly undesirable it fortunately doesn’t affect the performance of the device.

The OLED display is bright and clear showing all of the typical information you expect including Resistance, Wattage, Temperature etc. Just like all devices the main fire button has an LED behind it which alerts you to the current charge of the battery. The device features three buttons all of which are very well fitted, rattle free and highly responsive.

As already mentioned the device features a 4000mAh internal battery and the Micro USB Port is located on the bottom front of the device. There is no obvious battery ventilation on this device.

Ease of use

If you are familiar with any other Innokin device then you will be right at home here since they all tend to function the same way.

  • The LED behind the fire button lights green, yellow and red so you always know how charged the battery is. Green is fully charged, yellow is 50% charged, red means you need to recharge.
  • Three clicks of the fire button switches the device on and off.
  • To change the Wattage, hold down the plus button for two seconds until the Wattage starts flashing, then adjust with the plus and minus buttons. Wattage can be increased or decreased in 0.5W increments.
  • Hold the fire button and the plus button to cycle through Modes.
  • Hold the Plus and Minus Button down to flip the screen.
  • Temperature can be adjusted in 5° increments and displayed in either Celsius or Fahrenheit.
  • Hold down both buttons for five seconds to you flip the menu orientation.
  • When you fit an atomizer the device will ask you to confirm the Resistance and coil type.
  • Unlike some devices out there you can’t manually set coil resistance or lock it in Temperature Control Mode.


The Aethon chipset is in my opinion excellent and I could not fault this device at all when vaping in Variable Wattage Mode. In Temperature Control Mode I used the Uwell Crown III Tank got a consistently good vape with no weird Resistance fluctuation or heat spiking.

While the battery lasted I certainly enjoyed using this device because it felt comfortable and very responsive. Sadly the battery life is only average at best and in many respects seemed very short lived in comparison to my typical devices and I kind of wished this device was actually dual 18650 rather than an internal battery. For someone who vapes regularly like myself at an average Wattage it simply does not have a large enough capacity. On the other hand if you are someone who only wants this device for modest use the battery will last considerably longer.

The kit sent for review included the Scion Sub Ohm Tank which has been reviewed separately here. If you just want the basic highlights then it is a very good tank but one specifically intended for high Wattage Vaping and its performance varies greatly depending on whether you use the poor 0.5ohm coils or the superb 0.28 coils.

While I cannot fault the performance or the build quality of the Cool Fire Ultra TC150 it unfortunately isn’t perfect but then let’s be honest very few mods are. The slightly crooked 510 pin which can lead to a minor Leaning Tower of Pisa appearence with certain atomizers seems sloppy given Innokin’s typically high standards and definitely needs addressing. In addition the fact that there is something of a gap when using certain tanks and RDA’s I am sure will certainly annoy the more OCD vapers out there.

The 4000mAh internal battery is certainly an improvement but in my opinion it simply isn’t a large enough capacity for regular high Wattage vaping and becomes something of a limitation unlike a dual 18650 device which allows you to quickly swap the batteries out and continue vaping. Of course if you are more of a modest user the device becomes more viable but given that the kit includes the Scion Tank which requires very high Wattage for best performance it does seem to be something of a misstep. Personally I would be tempted to use the Cool Fire Ultra TC150 with a Kayfun 5 or an Innokin iSub VE at low Wattage because then the battery would certainly last you all day long and be very worthwhile but I think maybe it’s about time Innokin brought out a dual 18650 device.

The included Scion Tank is extremely good providing you only use the 0.28ohm coils but keep in mind you need 85-120W for the best results so in some respects this kit will only really appeal to those of you who like that style of vaping.

At the end of the day despite the device having some noticeable build flaws they thankfully don’t affect the excellent performance so I think if you simply wanted to purchase this device on its own or just get the kit for some occasional high Wattage cloud chasing fun then it might be very worthwhile but it will depend entirely on your requirements.

Many thanks to Innokin who kindly sent this product to Planet of the Vapes for us to review.
