Vaporesso just released their latest matchbox-style pod vape: the Vaporesso XROS 4 Nano. Complete with a whopping 1350mAh battery, fast charging, and a customisable interface, this little vape is a beast. Let’s take a closer look!
Vaporesso is on a roll with the XROS series. First, the XROS 4 and the XROS 4 Mini made their debut (with rousing success, I might add). Now, they’ve just released their latest Nano device, packed with handy features and plenty of battery life to keep you going.
The new Vaporesso XROS 4 Nano houses a massive 1350mAh battery complete with 2A USB-C fast-charging. It also features a large, round 1.3-inch TFT colour screen with customisable animations, various power modes, and adjustable airflow.
Vaporesso was kind enough to send us over a few units to test, and I was so excited to try it out. Let’s dive into my impressions of the device!
The Vaporesso XROS 4 Nano is a compact yet powerful pod vape from the Vaporesso XROS series supporting both MTL and RDTL styles. It boasts a large 1350mAh battery with 20-minute fast charging, offering up to four days of use on a single charge. The XROS 4 Nano also features a large, round 1.3-inch TFT colour screen and an attachable fabric lanyard for added portability.

Like the other Nano devices in the Vaporesso XROS vapes series, the XROS 4 Nano is a matchbox-style (meaning small and square) pod vape that’s ideal for carrying around with the included lanyard.
And while this is (at least) my fourth or fifth XROS device, it’s my first Nano.
I’m not usually huge on the matchbox-style vapes—I prefer something pen-shaped that I can slip into the pocket in my handbag and hold between my teeth as I do my hair in the morning (square models aren’t really conducive to hands-free vaping). However, one of my favourite vapes—the Aspire Riil X—had a similar shape, so I was really eager to try this one out.
As an aside, I was really pleased to see that Vaporesso has moved toward more eco-friendly packaging. They’ve removed the plastic shell inside the box, so now, there’s only cardboard. You have to open both ends of the box to get everything out of it, but it’s a nice reduction in plastic waste. Very neat.
As always, many thanks to our friends at Vaporesso for sending the units over for testing.
We were sent a couple of finishes, and I chose the Twilight Purple for this review. I’m not personally too keen on the big bubble-letter word pop finishes, but maybe that’s just me.
The front of the device houses the large, round 1.3-inch TFT colour screen with “Vaporesso” printed at the top, while the back plate is emblazoned with a small Vaporesso icon.
One side of the device features the airflow adjustment switch, while the other has the USB-C port and the small power/ fire button.
The bottom of the device has a flared base and is printed with the important battery and legal information, while the top of the device houses the pod and the lanyard connector.
Overall, the device feels very sturdy. It’s significantly heavier than previous Nano models, perhaps due to its much larger battery size and more premium materials. Still, I’m supposed to be wearing this on the given lanyard around my neck—and it’s quite heavy for an accessory.
I feel like I look like Flavor Flav.
The Vaporesso XROS 4 Nano feels very sleek and has a cool, retro-futurist aesthetic, particularly with the Race Track finish. It’s definitely a fingerprint magnet, though I know that doesn’t really matter to most people.
It looks stunning, of course—but let’s dive into its functionality.
The interface is the real stunner on the Vaporesso XROS 4 Nano. It has the largest-ever screen in the XROS series and boasts a lot of nifty features.
The feature I was most excited about was the various screen animations. You can choose between a space theme, a motorcycle theme, and a flower theme. I immediately chose the flower—and as you puff, the flower blooms and rustles in the wind. Very cool.
My favourite part about the interface is that it displays the battery in 1% increments—which means no more uncertainty while vaping. There’s nothing worse than a blue or orange LED indicator unceremoniously shifting to red between puffs.
I do take issue with a few parts of the XROS 4 Nano’s interface, though there’s also a lot to celebrate. Let’s dive in.
The airflow adjustment on the side of the Vaporesso XROS 4 Nano is sturdy and stable allowing for anything between a more restricted RDTL draw to a full MTL experience.
I really like the slider on this vape. It stays exactly where you put it and doesn’t tend to drift in transit, which is lovely.
It also, unlike some of the other models I’ve tried, doesn’t have set airflow configurations; you can freely adjust the airflow setting to suit your draw, exactly as you like it.
I really have nothing negative to say about the airflow adjustment feature on the XROS 4 Nano.
The fire button is located above the USB Type-C port on the right side of the device if you’re looking at the screen. It’s very small and sticks out from the side ever-so-slightly.
I wanted to give this part its own section because I’ve had a few issues with the button reading my inputs.
Now, I’ve owned more vapes than anyone could ever conceivably need or want. Suffice to say that I know my way around a fire button. I know how fast to multi-press, I know the general functions that most vapes use, and I was also assisted by the sticker that came attached to the body of the XROS 4 Nano.
It took me 4 tries to get the device to turn on. It took a further 3 tries to get the interface to lock. So, I handed the vape to my colleague so he could try it.
He was able to lock and unlock the interface, albeit by pressing the button much slower and more deliberately than I did.
It turns out that you have to press the button carefully and much slower and than with other models to access the multi-press functions. The button doesn’t register fast presses.
Perhaps Vaporesso wanted to negate the possibility of accidental unlocking and/or pocket firing in transport. A few times, I’ve found that my Vaporesso XROS 4 has unlocked itself in my handbag during my commute when it was pressed up against other things in my bag.
And while I don’t tend to use the button much—I usually find the power setting I want, lock the interface, and never touch the settings again—I can see this being an issue for others.
The Vaporesso XROS 4 Nano boasts that it has the largest colour screen in the whole XROS family—which is true.
Of course, it’s not a truly round screen; round screens are incredibly costly to produce, and if you look closely at the XROS 4 Nano’s screen while it’s off, you’ll notice a very slight reflection where the edges of the rectangular screen are set into the black circle. It’s even more evident when you use the vape in the dark. The edges of the screen stretch down below the bottom edge of the circle so that it appears to be round.
It’s very neat and shows incredible craftsmanship.
The screen is bright, legible, and the animations are lovely. It displays all the information you need to know, and some you don’t (like the puff counter, which very few vapers use).
All in all, I’m a huge fan of this screen, though as I said above, it looks a little ridiculous when I wear it around my neck. I won’t be wearing it outside of the house lest I be accosted and mocked by youths on stolen Lime bikes at the bus stop.
The Vaporesso XROS 4 Nano offers 3 power modes with the included pods: Normal, Eco (which produces less vapour and conserves battery), and Power (which creates bigger clouds but uses more battery). The vape doesn’t tell you the wattage settings for these, but most vapers don’t want (or need) to know. It’s automatically set to “Normal” when you pop in your first pod.
Now, when I opened the XROS 4 Nano, I said, “I remember this having adjustable wattage. Does it not?” I set the power output setting to “Power” and carried on, until the included pod ran out of juice and I swapped it with the filled 0.4Ω pod I’m using in my XROS 4.
That’s when I realised that the XROS 4 Nano shares something with the XROS Pro: it allows you to adjust the wattage, but only when using the 0.4Ω pods.
The problem? The XROS 4 Nano doesn’t come with any 0.4Ω pods. Meanwhile, the XROS Pro came with 2.
This is really strange. It feels like the included pods are an afterthought. A vape designed to allow for adjustable wattage doesn’t come with the pods needed to use that feature. Furthermore—and I‘ll get into this more in the section on pods below—the XROS 4 Nano comes with the old version of the Vaporesso XROS pods, not the new V2 pods.
It feels like Vaporesso ran out of the 0.4Ω pods mid-production, or they didn’t think carefully about which pods are included with this device.
Or maybe, after engineering the device, they decided that most vapers would prefer the higher resistance pods. Yet by including only the 0.6Ω and the 0.8Ω pods, they’ve effectively barred new users from trying out the adjustable wattage function altogether.
This feels like an odd choice (or a mistake) on Vaporesso’s part.
The Vaporesso XROS 4 Nano boasts a massive 1350mAh battery, which is roughly 35% larger than most of the other XROS models (excluding the XROS Pro, which has a 1200mAh battery).
Straight out of the box, the vape was about 60% charged, and it lasted me well into the next day before needing a recharge.
The XROS 4 Nano utilises 2A USB-C fast charging, and Vaporesso advertises that the vape takes only 20 minutes to reach 80% battery from 0%.
I tested this claim and found it to be true. To charge the vape to 100%, it takes about 40 minutes.
Thankfully, the vape also provides a handy estimate of how much longer it’ll take to fully recharge. I absolutely love this feature. This, paired with the battery level being displayed in 1% increments, makes up for a lot of the issues I have with the button and the included pods.
All in all, the charging is seamless, and the battery life is excellent—especially when using the lower-resistance 0.6Ω and 0.4Ω pods which tend to consume more battery per puff. I wouldn’t change a thing about the battery or the charging on the Vaporesso XROS 4 Nano.
The Vaporesso XROS 4 Nano comes with 2 pods included: one 0.6Ω (ohm) mesh pod pre-installed, plus a 0.8Ω (ohm) mesh pod spare.
These pods are designed for MTL and RDTL vaping, depending on your airflow setting, and are best suited for use with high-PG E-Liquids like nicotine salts and freebase 50/50 E-Liquids.
We don’t recommend using high-VG E-Liquids like shortfills in your XROS 4 Nano vape.
Now, interestingly, the vape comes with the original Vaporesso XROS pods rather than the newer Vaporesso XROS V2 pods.
This is really unusual given that Vaporesso hasn’t included the original XROS pods in any of their models since the XROS 3. We’ve had 3 XROS models since then—the Pro, the 4, and the 4 Mini—all with the new V2 pods included.
It’s just incredibly odd that they’ve reverted back to the original pods for this model. And they’ve been included to the device’s detriment, I’d say.
There aren’t many differences between the original pods and the V2 pods, though the V2 pods are taller (so it’s easier to see how much liquid you have left), and the clamshell top cap is slightly thinner, which makes it easier to snap off though more prone to cracking.
The top cap on the V2 pods being prone to cracking is an issue because it disrupts the vacuum inside the pod and can cause the E-Liquid to leak out, but given that you’re meant to replace the pod every week or 2, if the top cap cracks, that probably means it’s almost time to swap to a new one anyway. Plus, if it cracks, you can always just swap it with a cap from another pod.
All that being said, the main issue I have with the inclusion of the original XROS pods is that it’s very difficult to assess how much E-Liquid is left in the pod without removing it from the device.
Still, this can be remedied by simply buying a pack of V2 pods when it’s time to replace the ones that came with the kit.
The Vaporesso XROS 4 Nano comes included with the 0.6Ω and 0.8Ω mesh pods, which are ideal for both MTL and RDTL vaping styles. They pair beautifully with any high-PG E-Liquids you like, though I tend to go for nic salts.
However, given the vape’s 30W maximum power output, and given that the wattage is only adjustable with the 0.4Ω pods, I’m really surprised and confused as to why that pod wasn’t included with the device.
All of the promotional images on Vaporesso’s website show the device with the 0.4Ω V2 pods, though in an area of the page that I glossed over, it does say the vape is “compatible with” the 0.4Ω pods. Tricky.
I’ve checked the various versions of the kit that Vaporesso is selling around the world, and it appears that the “Global” and “CRC” kits (not sold in the UK) come with the 0.4Ω pod.
I have no clue why the UK and US versions don’t, but this feels like a mistake, especially because one of the main functions of the device (the adjustable wattage) is only accessible with the 0.4Ω pod.
Once you’ve got your settings and your airflow set how you like them, the Vaporesso XROS 4 Nano is an absolute breeze to use. Simply inhale on the mouthpiece or press the fire button when the interface is unlocked to vape. I prefer to use the inhale activation function.
I haven’t had any functionality issues when using the vape at all so far—no hiccups or faults to report.
All in all, once you’ve got the settings all configured, it’s a pretty unobtrusive device.
The Vaporesso XROS 4 Nano is an excellent choice for MTL and RDTL vapers looking for something more customisable than your average pod vape. It’s also a really cool-looking accessory, though perhaps too bold of a choice for me personally (see my note re: Flavor Flav).
I’d highly recommend this vape to fans of the square form factor who like lots of flavour from their high-PG E-Liquids. It’s a really nice upgrade to the less interface-heavy vapes without feeling too complicated. Almost like Baby’s First Vape Mod, though with far fewer settings and controls.
I wouldn’t necessarily recommend this vape to brand new users, though if you’re new to vaping and you want to learn how to operate a vape kit’s interface, you should go for it. I’d avoid this vape if you’re less tech-literate, and this should go without saying, but if you’re a sub-ohm vaper, this isn’t the kit for you.
I always try to include accessibility information on all of the vapes I review due to the sheer volume of smokers currently transitioning to vaping.
There are a lot of older smokers now trying vaping who may have issues with their vision or dexterity due to conditions like arthritis, and choosing a vape that’s accessible for this cohort can be challenging because of obstacles like fill ports, small buttons, and hard-to-read interfaces.
I think the XROS 4 Nano has a very accessible fill port, though that’s about as far as the accessibility goes. The button is very small, and while the screen is very large and bright—ideal for those who have vision issues—it’ll be hard to navigate due to the size of the button.
All in all, I wouldn’t recommend this model in particular if you have a vision impairment or dexterity issues. If you fall into one (or both) of these categories, I’d suggest either the Vaporesso XROS 4 or the Vaporesso XROS 4 Mini instead, which offer the same great fill port but with fewer settings.
Check out my Vaporesso XROS 4 & XROS 4 Nano Review for more on these devices!
This kit has a heck of a lot going for it, though there are some notable cons. I really haven’t had this many issues with a XROS device before (as you can see from my other reviews), but perhaps Vaporesso will rectify these in future batches.
Overall Rating: 4.44 stars
There you have it: a huge and way-too-detailed review of the Vaporesso XROS 4 Nano. This vape was an absolute pleasure to use, and I had a lot of fun writing this. Many thanks again to our friends at Vaporesso for sending over these units for testing.
If you’re looking for an upgrade to your simple pod vape, I would absolutely recommend the XROS 4 Nano. The screen is gorgeous, and I get such a kick out of watching the flower bloom with every puff.
