OXVA Oneo Review: One Vape, Two Vaping Styles

Despite being a relatively new vape brand, OXVA has quickly found a strong following among vapers. Under the leadership of experienced vape designer Justin Lai, who previously created some of Geekvape’s most popular devices, OXVA consistently launches clever and unique vapes.

One of the newest such devices is the OXVA Oneo, a seemingly simple pod vape that has the potential to offer a DL vape experience in a format more suited to beginners. 

Outwardly similar in design to the OXVA Origin Mini and Origin SE, the Oneo features a 1600mAh battery and 3.5ml pods. The pods are all sub-ohm, ranging from 0.4 to 0.8ohm resistances, and feature a fixed coil. No messy coil changes here, just whip out the used pod after a week or two and replace it with a fresh one. You also get adjustable airflow, 2A fast charging, and battery indicator LEDs. 

That’s a nice mix of features, but most are hardly unusual in the modern world of vaping. What, if anything, is clever or unique about the Oneo? Isn’t it just another pod vape? I’ve been testing one for the last week to answer those questions and more. 

This product was sent to me by OXVA for the purpose of this review. However, my thoughts and opinions remain honest and unbiased.

Design & Build Quality

The OXVA Oneo follows the same basic design as many modern pod vapes, with a few notable exceptions. Firstly, it’s shorter and fatter than similar pod vapes like the Vaporesso Veco GO or Caliburn G3. It is also non-symmetrical in profile, with almost a teardrop shape when viewed from above. This shape fits my hand (and, I assume, most other human hands) very comfortably.  

The second significant difference in the design of the Oneo is the removable cap that hides most of the pod. This is an unusual feature, and while probably not unique in the world of vapes, it isn’t something I can remember seeing previously. I’ve tested vapes with dust caps before, but this is different. 

This cap attaches with a satisfying magnetic snap and conceals most of the e-liquid reservoir, with only the drip tip exposed at the top. Two small cutouts let you see the fill level, so you don’t have to lift the cap off to check. The pod, which I’ll cover more fully in a moment, is also magnetically attached, so I can only assume this cap arrangement is for aesthetic reasons rather than structural integrity.

Running down the tapered edge of the device is a long LED light strip, and directly opposite is an airflow slider. There’s not much else to see, other than a bit of branding on the front and side. Both the body of the vape and the cap are made from aluminum alloy with a slightly brushed finish. It looks great and feels robust, a feeling further helped by the weight of the device. 

The Oneo is available in six different colors. The version I’m testing is Astral Black, and then you have Midnight Blue, Space Grey, Cool Silver, Sky Blue, and Phantom Pink. The colors all look pretty classy and, aside from the blue and pink that have slightly different tones on the cap, are uniform over the entire device. 

Pods

Beneath the metal cover you’ll find the pod or, if you prefer, the cartridge. The fixed-coil pods have a 3.5ml capacity unless you live in a region where TPD restrictions apply, in which case they will be 2ml. You get two pods with the Oneo kit, a 0.4ohm version is pre-installed, and there’s a 0.6ohm spare in the box. You can also get a 0.8ohm version, sold separately, if you want less DL and more MTL from the vape. 

The pods are standard in design, made from semi-transparent plastic that’s light enough to see the e-liquid inside easily. The drip tip is small and narrow, with a flattened oval shape that is comfortable to use and works well for DL vaping. 

The fill hole is on the side and, once the metal cap is removed, is accessible without removing the pod from its magnetic slot. I found it easier to remove the pod to refill it, as that meant I could wipe off any drips or spills from the bottle before reinserting. That said, the fill hole is a generous size, and the silicone bung can be swung out of the way when filling, so topping up the tank without making a mess is easy either way. 

Even without the added security of the metal cap, the pods felt secure in the slot and never like they were at risk of coming loose during my tests. If this is your first vape device, remember that you’ll need to remove the plastic film from the bottom of the pod before using it. 

The coils used in the Oneo pods feature the same Unicoil technology found in most other OXVA coils. Although I’m not 100% sure what makes unicoils different, they are well-regarded among vapers, and it’s nice to see them included in what are essentially disposable pods. We’ll take a closer look at how they perform in a moment. 

Features

The OXVA Oneo is, at heart, a pod vape system. As such, it isn’t hugely complicated or packed with advanced features. Once you get past the slightly unusual design, it’s plain to see that this is a simple and easy-to-use device. 

The wattage level is variable but there’s no way to change it manually. I can only assume that the internal chip senses the resistance of the pod being used and adjusts the power accordingly. This seems to work well enough, although there is no simple way to tell the wattage being used at any time, so you’ll just have to trust the vape. 

The airflow to the coil is adjustable, thanks to the tiny slider on the side of the device. This slider is quite stiff to move, which is both good and bad; good because it is unlikely to be altered accidentally in your pocket or purse, and bad because it makes fine adjustments a bit of a pain. 

The LED light is another adjustable feature on this vape. There’s no particular reason for this to be a thing, but it is. And the way you change the light color or effect is very unique. There’s no button, toggle, or switch, and instead, you have to draw on the vape three times in quick succession (under 1.5 seconds.) If successful, the new color or effect will be shown and the setting will stay that way until you repeat the process. 

Battery Life & Charging

Having a large 1600mAh battery in a pod/cartridge vape is a very nice feature, although the relatively high wattage and low resistance coils probably make it a necessity. I can’t help also wondering if the large LED uses a bit more power than the more common smaller ones. It’s unlikely to be much, but it would be interesting to compare the difference. 

Vape batteries and the internal chips that manage the power output have become much more efficient in recent years. My first ever vape (a mini box mod) also had a 1600mAh battery, yet that had to be charged every 5-6 hours, even when running it as low as 20W. With that in mind, the Oneo battery lasts reasonably well and should give up to a full day of use before it needs re-juicing. 

The LED strip displays the battery level by showing different colors after the draw light has finished pulsing. These are, again, similar but slightly different to most pod vapes, breaking the alerts down into four levels instead of three, as is more common. These are: 

• Green = 75-100% remaining
• Blue = 50-75% remaining
• Yellow = 25-50% remaining
• Red = 0-25% remaining

The USB Type-C port is sited on the base, which makes sense in terms of keeping the vape looking nice, but does mean that it needs to lay down when charging. Thankfully, considering the large battery, the port provides full 2A fast charging. In my tests over several days, the average time to completely recharge the battery from red was between 50-60 minutes. 

Performance

The OXVA Oneo is much more suited to Direct Lung vaping than to MTL, but it can be used for both vaping styles with a bit of adjustment. I only had access to the 0.4 and 0.6ohm pods, and so tested the vape as a DL device. And in this configuration, it really works well. Using a range of liquids with 50/50 and 60/40 ratio of PG/VG, and low-to-mid nicotine strength (10mg/ml,) it produced excellent flavor and a distinctly satisfying throat hit. 

Choosing the optional 0.8ohm pod and closing the airflow should provide an acceptable mouth-to-lung experience. There are almost certainly better pod vapes available if all you want is MTL, but it’s nice to have both options in a single device. Using nic salt liquids in the low-resistance pods is likely to be a bit harsh, but you could probably get away with it in the 0.8ohm version. 

True cloud chasing isn’t really on the cards with a pod vape like this, but vapor production is good, and it’s possible get a decent plume going if you desire. The airflow makes a huge difference to the vape experience with the Oneo, more so than on most pod vapes I’ve tried. When the slider is fully closed, the draw is pretty tight, and the vapor gets warm quickly. But if you open the airflow right up, the draw is as loose as some sub-ohm box mods I’ve used. Impressive from such a small pod vape!

The coils seem efficient and both of my test pods are still going strong after more than a week of heavy use. There’s no hint of burning in either pod, although both have suffered from a bit of leaking. It isn’t a large amount of liquid and generally seems to be after refilling, so could be down to user error rather than a design flaw. 

One gripe I have is that condensation forms in the drip tip almost instantly and is very noticeable. This could be due to the conical shape inside the mouthpiece and the relatively wide aperture. I have no idea if this problem can be designed out of a vape, and it’s probably not a deal breaker, but it never looks very nice. 

Verdict

The OXVA Oneo is a great option for someone who wants to try DL vaping without the time investment or learning curve often associated with using a sub-ohm box mod. For around $25, you get an excellent DL experience, with the option to switch to MTL easily, so you don’t need to run two devices to be able to match your vape needs on any given day. 

The flavor and throat hit are very satisfying, and as long as you choose your vape juice carefully, the Oneo comes as close to giving the box-mod-experience-without-being-a box-mod as I’ve seen in recent years. 

If you’re upgrading from a low-power pod vape, you’ll likely be surprised that the 1600mAh cell doesn’t last much longer. It’s true that the battery life could be better, but it isn’t terrible when you consider the wattage being used by the vape. Low-resistance coils require more power, and if you want DL vaping in a small device, that’s something you’ll have to get used to. 

The design and build quality are also excellent, and everything from the strong magnets to the stiff airflow slider tells you that this is a well-thought-out device. You could argue that the cap and LED effects are gimmicks, but they add to the overall look and feel to make this a unique and interesting pod vape.
