It’s the simple things in life that matter. Since joining the Spinfuel team, I’ve had the pleasure of vaping some of the world’s most elaborate mods, atomizers and e-liquids. With varying results. For as much fun as we have playing with touchscreens, color light shows, custom temperature curves and the like, it’s easy to forget that vaping doesn’t have to be complicated. Sometimes, a power source, a good atomizer and some tasty e-liquid are all you need. This is clearly the thinking Asmodus employed with the all-new Oni 80W kit. But make no mistake, in this case, “simple” doesn’t mean “underperforming.” Let’s explore this a little further.

Understated, inside and out…

Unless you went to a shop seeking out the Asmodus Oni 80W kit, it’s not likely to jump off the shelves while browsing. Coming in a plain, black cardboard box, with an equally minimal foam insert, and just a few odd “demon” graphics to accompany the stark layout.  Asmodus had a theme here and ran with it.

One item of note – Asmodus is a US-based company, and the Oni 80W is made entirely in the United States. We know that matters to a lot of you, and it warrants mention here.

Inside the box, you’d be forgiven for missing my black test model amid all the other black in the package. But it’s in there, and depending on your perspective, it’s either shockingly boring, or strikingly reserved. Once removing it from the box, you get a better sense of the Oni’s subtle beauty.

Made from a durable, textured zinc alloy frame, with a standard boxy shape, the Oni is all about ergonomics. It’s lightweight, but solid in the hand, and the slight texture on the surface means the Oni sits comfortably in the palm, with little risk of slipping and sliding.

Despite the miniscule form factor, the Oni 80W can handle most tanks up to 25mm wide without overhang. Using a series of tanks, I was happy to see all sat flush on the press-fit 510 connection, with no wobble or gaps.


Plus, the slender profile and powerful 2800mAh internal battery ensure the Oni is the perfect “on the go” device for people who want to minimize their rigs when out for the night. The large, firm fire button, half-moon shaped control buttons and circular OLED screen are as understated as the rest of the device, and function well in pockets, furthering the Oni’s portability.

The only creative design aspect of the entire device is the monochromatic, steaming devil logo/mascot that adorns the side of the chassis. I think he looks cool, but most of my wardrobe involves demons and band logos, so I might not be the best guy to ask. I could imagine the target market for this device might have preferred complete subtlety here, rather than this odd graphical flourish.

As a nice touch, even with the smallish form factor, Asmodus was sure to include plenty of vent holes throughout the Oni, which kept things nice and cool, even when cranked to full power. Speaking of which…

Oni 80W - Under the hood...

The Oni 80W features a new chipset – the GX80-HM — which brings users up to 80 watts of power, in wattage mode, and up to 572F in the comprehensive Ni/Ti/SS316 temperature control suite. Continuing the thread of simplicity, the chipset seems to work effortlessly. The simplified menu system clearly presents selections with a click/hold scheme with which most vapers are well familiar.

Navigating and selecting options was fairly easy, though I did find myself struggling at bit when setting TCR values, as the device seemingly kept backing me out to the previous tier of the menu tree. Once I had it “down” it became second nature, but new users might experience a little frustration at first.

Choosing wattage settings is much easier, and even vape novices will have the mechanics down in no time.

Oni 80W Kit - Simple Mod. Simpler Tank.

The Asmodus Oni 80W kit comes included with the 24mm Ohmlette (let’s rethink this name, Asmodus) sub-ohm tank, which arrives with an installed 0.4-ohm direct lung coil, alongside an additional 0.8-ohm coil better suited for MTL vaping.

With a squat, nondescript format, stainless steel construction, bottom airflow control, and semi-wide-bore Delrin drip tip, the Ohmlette tank isn’t going to win any innovation contests. But vaping is a practitioners hobby, and it doesn’t really matter if this thing is hideous, as long as it works well.

Well, the Ohmlette isn’t quite as memorable as its name, but it works well enough to make it a consideration when taking the Oni out for a spin.

First using the 0.4-ohm coil at an average of 60 watts, the Ohmlette put out a nice cloud of vapor, with subdued, but adequate flavor. It was a pleasant experience, but nothing that was going to make me forget about similar sub-ohm tanks in this category.


I should also mention that the 0.4-ohm coil was surprisingly thirsty, considering how conservative the flavor and vapor production turned out to be. The coil itself was a trouper, lasting well past a week of steady use. But I felt as if my constant refilling wasn’t proportional to the flavor and enjoyment I experienced with the Ohmlette.

Switching to the 0.8-ohm coil at a more-conservative 40 watts, I enjoyed slightly improved flavor, and similar vapor, but ultimately, it all felt muted. However, the 0.8-ohm coil was much more frugal on e-liquid, and subsequently, my preferred coil when taking the Oni/Ohmlette combo out for the day.

In the end, I didn’t mind using the Ohmlette, and enjoyed the way the tank/mod combo worked together. However, as I found later in my testing, the Oni is clearly eager to make new friends.

The Asmodus Oni 80W Can’t be Monogamous

Switching to more-proven sub-ohm tanks and RDAs proved to bring a little more life out of the Oni. From MTL-focused RTAs, to low-built drippers, the Oni worked well at all temperatures and wattages I threw at it, never once getting hot or misfiring.

Using my trusty OBS Engine RTA, with a conservative 0.75-ohm Kanthal build, the Oni became a flavor-first, ideal pocket combination – with more than enough vapor production to make this a satisfying, attractive pairing.

Obviously, because of the size and maximum output of the Oni, I wouldn’t recommend this for vapers looking to chuck clouds all afternoon. The 2,800mAh internal battery does a nice job, but this isn’t designed for all-day vape fests, either. That’s not to say it can’t perform at higher wattage – it does. But this is really about convenience and portability, more than power.


Instead, the Oni is perfect for casual vapers, or those looking to have a rock solid, reliable backup device for road trips, or just when your standard rig isn’t so pocket-friendly

Because the Oni 80W may be simple, and the Ohmlette tank may be average. But those who meet the above criteria will be hard-pressed to do better than the Oni 80W Kit.
