If you haven’t heard of Innokin, the brand is known for a few of their device lines, such as the iTaste, iSub, and CoolFire devices. Their products are sold internationally, as well as in more than 500 vape shops in America. Innokin has been a pioneer in vape tech since they began producing products in 2011. The Innokin CoolFire Mini Zenith D22 MTL Kit is one of their recent releases, and since a lot of MTL kits—especially pod mods and all-in-ones— have taken over a  lot of the industry, I wanted to give this one a shot.

The Design

The look of the Innokin CoolFire Mini Zenith D22 MTL Kit is reminiscent of Innokin’s Kroma-A 75W mod’s design. It impression is sleek and modern, with a simplistic design that melds together well into one handsome unit. One thing you’ll be able to notice right away is the size of this kit. It’s very compact. If you have larger hands, it’s almost invisible! With that in mind, it’s a nice kit for portability and stealthy vaping.

The CoolFire Mini kit is available in black, blue, pink, gold, and white. Note that the gold and white finishes end up with an ombre effect toward the bottom, which means the gold or white colors fades into black at the bottom end of the mod.

The Build

Although this kit is lightweight, it’s made very well and doesn’t skimp on the materials. The chassis is zinc alloy with a side-mounted OLED screen and a gold-plated 510 connection. On the front face of the mod, you’ll see the firing/power button, the OLED screen, two adjustment buttons, and the micro-USB port. If you look around, you’ll also notice some venting along the sides, which will keep the device nice and cool when you’re vaping.

To turn on the kit, it’s five clicks of the firing button. On the display screen, you will see the resistance, output voltage or wattage, the output mode, battery life, and a puff counter.

The Zenith D22 Tank

One of the best parts of this kit is the Zenith D22 tank. It’s a 22mm diameter, holds 2ml of juice (which is perfectly acceptable for MTL vaping), and uses the Zenith coil series. It’s made of stainless steel, a 4mm Delrin 510 drip tip, and has a nice 510 connection. To fill the tank, you just unscrew the top cap, as it’s a threaded system. The fill port is large enough to fill without much mess at all.  

Since this is an MTL kit, the adjustable airflow is a series of four incremental holes. The largest hole is 2mm and the smallest is 0.5mm.

The Zenith Coils

The two coils included in the Innokin CoolFire Mini Zenith D22 MTL Kit? A 0.5-ohm coil for 4-19W and a 1.6-ohm coil for 10-14W. These are both excellent MTL coils, made of kanthal material, and easy to put in and take out, as it’s a plug and pull type coil. To keep it even more mess free, there is a juice control system that kicks in when the top cap is twisted off.

If you like a slightly warmer vape, the 0.5-ohm coil is a better choice, but if you’re looking for a coil with a cooler vape, that’s excellent with nic-salts, the 1.6-ohm coil is the way to go.

Vaping the Innokin CoolFire Mini Zenith D22 MTL Kit

First impressions of this kit were already good. The small, ergonomic design is simple and discreet. Charging and filling the tank was painless, though the charge took close to an hour to reach full capacity. The internal battery is 1300mAh, so even vaping this kit at 19W, I was able to get more than a full day of vaping out of the battery.

I was most impressed with the flavor from the Zenith coils. Sometimes, I’m a bit hard to please with MTL kits because I’m used to flavor from RDAs and mesh sub-ohm coils. In my opinion, a warmer vape just brings out the flavor more than a low wattage, low power vape. But the flavor was quite nicely balanced, even as low as 10W. With nic salt juices, as well as a high concentration juice, these coils really shine. In fact, I suggest just completely skipping over using these with regular, low nic liquids. For a good MTL, those will not do this kit any justice.

Does the Innokin CoolFire Mini Zenith D22 MTL Kit Impress?

For a simple, flavorful MTL vape, this kit is a nice one to have. The small size makes it easy to bring anywhere, plus you don’t have to worry about external batteries. While I can’t see myself recommending this to vapers who’ve been on the scene for a lengthy amount of time, I really think that this kit is more geared toward beginning vapers or those who want a no-fuss MTL kit. The battery life is good, the tank is nice, the airflow works well no matter how tight you set it. There aren’t many negatives.

The Innokin CoolFire Mini Zenith D22 MTL Kit does what it promises, and though this isn’t a unique or revolutionary set up, it’s perfect for some vapers who just want simple goodness.
