Innokin Kroma-A Review: Breakdown

Constructed with a solid Zinc Alloy chassis, the Kroma-A mod is definitely going places. And when I say this, I mean that it’s a pretty robust device. the mod features a knurled, textured grip that feels quite good to hold and inspires confidence that this device won’t be accidentally slipping out of your fingers anytime soon. The front of the device holds the clicky and quite tactile firing button that responds almost instantly upon pressing. The same quality extends to the up and down wattage buttons also located on the front of the mod.

The Kroma-A utilizes a tiny OLED display located on the side of the device and despite its diminutive size, the screen is quite informative showing remaining battery life, wattage or temperature settings, atomizer resistance, vaping mode, and even a puff counter for those who like to pay attention to such details. In addition to this, the mod also supports an LED indicator on the firing button which uses various colors to indicate remaining battery life.

Close to the bottom of the Kroma-A is a Micro USB port which is used for charging the mod with its handy dandy 2 amp charging rate. Surprisingly enough, you won’t find any battery venting holes but Innokin ensures us that in any scenario should the internal battery of the Kroma-A vent, it would do so through the micro USB port. The top of the device features the gold plated 510 connection which is a nice touch. It supports atomizers up to 24mm in diameter making it somewhat versatile especially when considering this is only a 75-watt device.

Inside the kit, you’ll find the Innokin Kroma-A device itself, the Innokin Crios Sub-Ohm Tank, two 0.65 ohm Crios BVC coils, an 8mm bore Ultem drip tip with an 810 connection, a 510 drip tip adapter to fit all your custom drip tips, a single micro USB cable for charging the device (no promises of upgradeable firmware), spare o-rings and glass tank, an Innokin Vape band which is handy for protecting tank from nasty falls, and the standard user manual.

The Crios tank looks quite promising with its large chamber and wide array of airflow configurations. Sporting a 24mm diameter and triple fully adjustable airflow slots, the Crios allows for a wide open airflow which gives tremendous amounts of vapor. If you prefer a tighter and denser draw, the Crios allows for this as well as the airflow slots taper off quite nicely and reduce the amount of air taken in without sounding too whistly and turbulent. One thing I liked most about this tank is that airflow can be fully closed preventing the chamber from leaking which is especially useful when leaving a large amount of eliquid unvaped in the tank for extended periods of time.

The two BVC coils included in the kit perform identically well which is a good indicator of consistent quality control among their coil heads. Flavor and vapor production is full and dense, easily bringing out the subtleties of your preferred eliquid. Coil life is neither bad nor good and performs up to par with the majority of options available by competitors lasting about 5-7 days depending on the quality of the eliquid you’re using. Another thing I liked about the coils is how fast they wick eliquid requiring little time for priming and never experiencing any dry hits even when chain vaping at higher wattages.

The Crios tank holds up to 4ml of eliquid making frequent refills a thing of the past. Refilling is easy and straight forward which only requires threading the top cap off and dripping straight into the tank through the large ports found on top. The tank has yet to leak even when using thinner, higher PG eliquid which is always good to see.

The AETHON chip used in the Kroma-A supports all the standard temperature control modes such as stainless steel, nickel, and titanium. I had the opportunity to test out the TC accuracy with the included stainless steel coils and I’m glad to see that the output felt accurate and consistent while still managing to deliver satisfying hits. The mod also refused to fire when the tank was close to empty, preventing dry hits which hints to the accuracy of the temperature control itself.

Aside from temperature control, pre-heat in wattage mode is also supported allowing you add an extra little kick to your vape every time the fire button is pressed. While customizable TCR curves are also supported I didn’t get the chance to test it out, but if its anything like the temperature control on this mod, chances are its darn good as well.



The Kroma-A is compact and stealthy little device, easily palmed in the hand and conveniently slipping into even the tightest of pockets.

While the 2000mAh internal battery means you won’t be getting through an entire day of high wattage vaping, the 2 amp onboard charging lets you power the device back up to full charge in a jiffy.

The Kroma-A kit is overall a solid package to consider especially for beginners who are looking for their first regulated device without all the hassle of getting separate batteries and chargers. It vapes well and produces lots of flavor, even to the point that advanced users might consider this as a handy backup device when when in need for something a bit easier to carry around.

If you are looking for something a bit more portable check out the SMOK G150 and if you are looking for more power check out the SMOK Procolor.
