Tools Of The Trade & Safety Information

People can suffer from allergies to chemicals that may be present in the makeup of certain types of E-liquids or produced in their vapour. People can become sensitive to, or even allergic to Nickel or Titanium used in Temperature Controlled designed coils. Seek professional medical advice before using any of the products used in my reviews.

In this review, I have used a selection of E-Liquid flavours from Five Ten Vapers extensive range.

Bang For Your Buck

The Device

Kroma A 75W-TC

Starting from the top of the device you will see that the Kroma A incorporates a copper spring loaded 510 connector and allows for a tank diameter of up to 24mm.

The surrounding top plate is slightly raised in order to avoid damage to the paint work when you are attaching the tank to the device, which is a further example of the attention to detail shown by their engineers when designing a new device.

An Anti-slip grip has been added to the overall stainless-steel body which will help to minimise the risk of dropping it accidentally.

Positioning of the OLED screen on the side panel provides the user with instant feedback to the status of all the functions that this advanced box mod has to offer.

And with three well placed input buttons that include the on/off switch at the top of the front panel and the plus and minus input buttons just below it, operation of the Kroma A could not be more straightforward.

Situated on the bottom plate and right underneath the minus – button is the micro USB port for charging the device.

To turn the Kroma A on once you have filled and attached your tank only requires you to press the power button three times in quick succession. To turn it off press the power button three times again using the exact same method.

The plus+ and Minus- input buttons allow you to increase or decrease the current values.

By using different combinations of the Power, Plus + and Minus – buttons, you will be able access all of the menus and functions. A more detailed description of these can be found on the quick start guide supplied with the kit.

The Kroma A has an adjustable wattage range between 6-75W and includes   Temperature Control supporting (SS316, ni200, Ti wire) from 200 – 600°F |100 – 315°C with dry-hit protection. With a ramp up time of 0.2secs.

Power is supplied by an internal 2000mAh Li-Po battery with 2amp micro USB quick-charge capability with vape while charging’ technology also included.

The heartbeat of the Kroma-A is supplied by the reliable Aethon chip. And like all working parts from the Innokin stable, built to last.

For a more in-depth view of the Kroma-A Kit and its features, please consult the included user manual.

The Axiom M21 Tank

Constructed from stainless steel and Pyrex glass and meeting the requirements set out by the TPD, the Axiom M21 Tank is designed with a maximum e-liquid capacity of 2ml.

Designed primarily with the cloud chaser in mind, the Axiom M21 Tank surprisingly produces excellent flavour as well.

With an ultra-low profile wide bore drip tip reducing the overall distance to the coil head, and fitted with a pre-installed dual horizontal coil, you will quickly understand why as this is the preferred setup used in RDA setups.

You will also find an alternative 0.65 Ohm vertical coil included in the Kroma A kit. Innokin recommend wattage settings between 20W and 65W respectively when using these coils. The exact recommendation can be seen on the coils themselves.

It has a simple top fill design which can be accessed by unscrewing the top cap and pouring your e-liquid into the tank via the three inlets.

Airflow is supplied by three inlets which can be adjusted to suit your preference. Remember, these tanks are not designed to provide the vaper with a restrictive draw. It is also important to remember that this tank should only be used in Variable wattage mode.


The Good

Packaging. If you want to know how to present your products to the consumer, then look no further.

Compact and easy to use with a plethora of inbuilt vaping options to suit all levels of experience, and as we have come to expect from Innokin, backed up by first class engineering, the Kroma A numerous safety features and driven by the Aethon chip means you really can’t go wrong.

The upgraded near flush mounted 24mm 510 connection is a perfect fit for all popular atomizers of this size.

You have a choice of vaping styles that includes, variable wattage mode and temperature control mode with the three most popular wire types supported.

Dry hit protection in temperature control mode burning works like a dream.

Innokin have opted to offer two types of tank with this kit, one of which, the Axiom meets with the current requirements set out by the TPD for European vapers. The overall performance was very impressive given its size producing plenty of clouds and excellent flavour.

It would be nice to see a larger version of the Kroma A with increased battery capacity. 2000mAh is clearly sufficient for a device of this size, but 4500mAh would be even better!

And finally, a full 90 day warranty period!

The Bad

All points raised by the vaping community seen to have been fully addressed in this model.

I have however, noticed some rattle which appears to be coming from the power button.  I hope this issue can be addressed prior to the final release.

The OLED screen although stylish, is a little on the small side. To improve this short term a different type of glass could be installed which would make viewing of the information just that little bit easier to do in bright conditions.

And The Downright Ugly

I have not come across anything negative to report so far on the Innokin  Kroma A Kit. It’s a rock-solid device, and a suitable traveller’s companion without question.

Great job on this one Innokin!
