Today I’m taking a gander at the latest pod kit from Vaporesso. It’s the Vaporesso XROS 3 Nano and it does look kind of familiar.

Vaporesso Xros 3 nano pod kit hand check imageSince 2015, Vaporesso have been committed to making a difference to the lives of their customers. With 14 industrial parks and millions invested into research and development, one wouldn’t have much difficulty in believing that.

In fact much of the research is based around nicotine satisfaction, flavour and device performance – three key attributes that make for a happy vaper in my opinion.

Back in 2020 our own Flatcap Vaper reviewed the original XROS pod kit. As pocket friendly as it was, the series went on to spawn an even smaller version in the form of the XROS Mini.

The XROS Nano also made an appearance with its boxy, flattened look – a design that’s as popular today as when first released.

This leads me nicely onto the subject of the day – the 8th version in this popular series of basic starter pod kits.

So the question is, does familiarity really breed contempt or is the Vaporesso XROS 3 Nano a worthy addition to your vape catalogue?

What Can We Expect From the Vaporesso XROS 3 Nano Pod Kit?

A very basic pod starter kit!

One that relies entirely on auto draw (simply inhale on the pod to vape) and uses a coloured LED for functionality. There’s no screen to fiddle about with and the only thing you need to adjust is airflow.

The pods are backwards compatible with others in the series and depending what you pick up will be suited to salt nicotine or freebase E-liquid types.

Vaporesso XROS 3 Nano pod compatibilityIt comes with a brand new 0.6ohm pod, designed for an RDL vape (Restrictive Direct Lung) as well as one for a MTL (Mouth To Lung) pull.

We tell you what the terms MTL and RDL mean in our Guide To Vape Styles.

Pod Corex Heating and SSS Tech

The pods include sealed, non removable coils and the COREX heating tech has been applied with its “Morph Mesh” structure to ensure a faster, even and more consistent vape.

xros 3 nano corex

SSS technology also makes a welcome return ready to seal, store and saturate that fluffy white COREX cotton. The Vaporesso XROS pods aren’t known for dry hitting – always a reassurance to the new or seasoned vaper.

For those techy minded, each pod is enhanced with improved vaporisation properties – said to be 50% more efficient than others.

.. Maybe it’s the use of big words. Big words and technicalities tend to go together!

Anyway, Vaporesso state the pods can theoretically last for up to 20 days use.

Vaporesso XROS 3 nano leak resistance and top fill features

The pods employ a top filling system that in my opinion is the best and most effective way to get E-liquid into the pods.

Power is boosted by the Pulse mode of the AXON chip which in turn should see the battery lasting for anything up to 48 hours.

.. Not sure that’s gonna work with a chain vaping freak like me!

Vaporesso XROS 3 Nano battery capacityThe Vaporesso XROS 3 Nano is available in standard and TPD versions. They’re the same and both pods have a 2ml juice capacity.

You can pick it up in a host of funky colours. Choose from Silver (under review), Black, Navy Blue, Olive Green, Rose Pink, Magenta Red, Lilac Purple, Lemon Yellow, Vital Orange or Bondi Blue.

Oh! almost forgot.

You also get a free lanyard. Not that I ever use them. Pockets are fine but the option is there if you’re happier wearing the device around the neck.

Design and Build Quality

Battery section

It’s the standard design for a Vaporesso Nano device.

That’s to say it has that flattened, Square look. I’ve never found this design to be as comfortable as a traditional vape device. The fact the edges aren’t rounded off doesn’t really help things and it’s noticeable when held in the hand.

However, it is very slim and easy to hide so avid vapers won’t have much trouble concealing it for a cheeky stealth vape or six.

Side of Vaporesso Xros 3 nano pod kitIt looks like it’s made from a tough Aluminium Alloy which helps to keep weight to a bare minimum. The words ‘Vaporesso’ are repeatedly embossed diagonally across one side with the logo emblazoned on the other.

Some may say this is a bit self indulgent but I actually like it. There’s a classy mirrored finish to the design and works especially well with the Silver version.

A wide but narrow LED indicator has been placed in the bottom corner.

Black plastic trims lines the sides and bottom of the device. Even these have a Crocodile Skin style texture. I like this attention to detail.

Dual Airflow Structure

So there’s a single fixed airflow hole on the front and another larger one built into the adjustable airflow slider beneath. The slider protrudes slightly but not enough to distract or get in the way while vaping.

Adjustable airflow slider on Xros 3 nano pod kit.. Let’s just say it’s much better than having a nail sticking out!

A type C USB charging port is incorporated into the bottom of the device. I do prefer them to be side mounted but it is what it is.

I think Vaporesso have missed a trick here because the kit stands very solidly on any surface.

The Plastic trim does provide additional protection for the USB port and it’s recessed enough to prevent damage to the contacts.


Peering down inside the battery section I can clearly see two Gold Plated spring loaded coil/battery contacts, an air ingress tube and two magnetic contacts for pod retention.

You’ll be pleased to know the pods fit either way around.

Speaking of the pods..

Pod Section

It follows on from the tried and tested design of previous 2ml XROS pods in the series. If it ain’t broke don’t try to fix it, that’s what I always think.

Vaporesso Xros series 0.6ohm pod image
The installed 0.6ohm XROS series pod

So we get the same “Duckbill” style mouthpiece that’s specifically made for RDL or MTL vaping. It feels comfortable when pursed against the lips, so no complaints from me!

Snapping the mouthpiece off reveals an Orange coloured fill port as well as an air release vent. These vents should be mandatory on all top filling pods as they drastically reduce the likelihood of spillage and over filling.

Top fill port on the Vaporesso Xros 3 nano pod kitThe pod is made from a toughened, clear PCTG material and you’ll have no problems viewing remaining E-liquid levels within. The entire content is viewable while attached to the battery section. Now that’s always a plus.

It snaps reassuringly into place inside the battery and the magnets are strong enough to hold the pods in position even when dropped from height. I tested that!

Vaporesso XROS 3 Nano Quick Start Guide

How To Fill the Pod

It’s much easier to fill the pod while attached to the battery.

  • Snap the mouthpiece off the top of the pod
  • Locate the Orange fill port and carefully push an E-liquid bottle nozzle into the fill chamber. Never attempt to pour E-liquid down the black centre hole. This will only flood the coil and ruin the pod.
  • How to fill the Xros 3 series 0.6ohm podGently squeeze E-liquid into the chamber until full
  • Snap the mouthpiece back into place
  • Let the E-liquid soak into the cotton wicking ports for around 5 minutes prior to vaping for the first time

Filled pod Vaporesso Xros series 0.6ohmNote! The installed 0.6ohm pod comes with a sticker attached to the base. Remember to remove this when filling for the very first time.


There’s not much to it. That’s the beauty of the XROS range of devices. It relies entirely on auto draw. So how are you going to know the condition of the battery?

It’s all done with that single LED down in the corner.

  • 100% – 70% Green LED
  • 70% – 30% Blue LED
  • 30% – 0% Red LED

These colours are briefly shown after each vape. You can also always check remaining battery strength by temporarily removing the pod.

Safety Precautions

The LED also responds to any issues the battery may be experiencing.

  • Low resistance / short circuit / high temperature – LED flashes Red 5 times
  • No load / high resistance – Current LED colour will flash 5 times
  • Low voltage / over discharging – Led flashes Red 3 times
  • Over charging – LED remains Green and device stops charging
  • Over vaping – LED flashes Green, Blue, Red

In all cases the device will temporarily cease to function.

How To Charge the Device

I found the review model to be fully charged straight out of the box but you’re inevitably going to have to recharge it yourself at some point. Here’s how.

  • Connect the smaller end of the supplied type C USB cable into the bottom of the battery section
Charging the Vaporesso Xros 3 nano pod kit
Don’t try to force the cable all the way in. It simply snaps into place as shown.
  • Connect the larger end of the cable into a suitable USB outlet
  • The LED will start pulsing Red as it begins its passage through the charge cycle. After ten minutes it switches to Blue. After a further 25 minutes it changes to Green.

It takes around an hour to fully recharge the battery. The Green LED will turn solid once complete. It’s possible to continue vaping while the device is being charged.

Vaporesso XROS 3 Nano Pod Kit – How Does It Perform?

0.6 Ohm Pod

I used Digbys Custard Cream to test the pod. It’s a personal favourite of mine and with a juice ratio of 65VG/35PG should be well suited.

0.6ohm Vaporesso Xros series podAirflow Wide Open

The slider was positioned wide open to test for a restrictive direct lung vape. How did it fare?

Well it’s certainly restrictive yet on par with what I enjoy from this style of vaping. The inhale is smooth, relatively quiet and I get a slight tickle from the 3mg freebase nicotine applied to the flavour.

Auto draw is hyper sensitive, reacting to the tamest of tugs and the flavour is excellent.

The Custard, Cream and Vanilla all tumble from the exhale and flavour is consistent throughout. From start to finish.

I’ve no problems on that score. It’s a very concentrated and clean vaping experience and I’m getting everything that’s printed on the bottle labelling.

When vaping RDL style I was actually surprised by the vapour production. There’s much more volume than I expected. Great stuff!

Airflow Restrictions

This is where things took a tumble for me. I reduced the airflow on the slider to around mid-way and still couldn’t get a satisfactory MTL vape. In fact it felt like my lips were stinging after a few seconds of inhaling.

Not only that but the flavour had taken a turn for the worse. It was still there but very much subdued. All the richness and vibrancy of the RDL setting was missing, replaced with a dumbed down, diluted version.

Closing the airflow slider completely gave me an entirely different experience.

By relying on the single fixed airflow slot, this was now an acceptable MTL vape although the stinging factor persisted. Quite distracting, if I’m completely honest.

The flavour improved marginally but nowhere near as focussed as it could be. Vapour production was suitable stealthy and I had no issues there.

0.8 Ohm Pod

This time I used TenTen Heisberry Ice. It’s a 50VG/50PG E-liquid ratio with 20mg salt nicotine included.

0.8ohm Vaporesso Xros series pod

Airflow Wide Open

I got something of a respectable MTL vape although still a bit loose for my personal liking. Again the inhale was silky smooth and quiet with vapour production perfectly mimicking that of cigarette smoke.

Flavour quality was great from this pod with the airflow slider set wide open and felt very consistent from start to finish. The Menthol qualities were just about right for my liking and didn’t smother the vape experience.

Yes, you can still RDL vape and the flavour in my opinion is even stronger and concentrated but it does begin to pull on the ‘ole neck muscles a bit!

Further Airflow Restrictions

Now here’s where the difference between the two pods really comes into play. By reducing the airflow slider to around mid position, I got the ultimate MTL vape.

The restriction was about as good as it gets.

The fruity flavour was banging and the Menthol properties blended in perfectly, leaving their mark post vape. Just as it should with this particular profile.

In other words, there was an improvement to the flavour instead of a dilution as was the case with the 0.6ohm pod.

Of course if you’re lazy with airflow sliders you can just shut it off completely and rely on the single fixed airflow slot.

You’ll still get a MTL experience but it does feel forced and not as natural when restricted to this extent.

The pod can just about manage a RDL vape but honestly does shine as a MTL vape with the slider around mid position.


Battery Performance

I wasn’t overly impressed if I’m honest and that’s because of the claims being made. I managed around 7.5 hours continuous use – I knew I wasn’t going to be vaping for much longer with a battery rated at 1000mAh.

Vaporesso state up to 48 hours. That may well be possible but only to a very infrequent vaper. Someone that isn’t reliant on their nicotine fix. I chain vape so that tells you everything about me!

So just be aware the device is likely to last the average vaper anywhere in the region of 24 hours, tops.

I also noticed a drop in output as the battery depleted. It almost felt like the pods were unable to keep up with the demands of wicking as the charge passed from Blue to Red on the LED.

It’s nothing major but enough for me to notice.


  • Lightweight and pocket friendly
  • Great flavour from the 0.6ohm pod. Even better flavour with the 0.8ohm pod
  • Good vapour production with either pod
  • The sealed pods won’t leak
  • Extremely easy to fill without having to remove the pod
  • Ability to view all remaining E-liquid levels
  • Fast one hour type C USB charging


  • Flavour from the 0.6ohm pod suffers if restricted too much
  • 0.6ohm pod can sting the lips on extended RDL inhales
  • Positioning of the LED (subjective)
  • Horizontal charging (subjective)
  • Average battery life

Final Review Verdict

So it’s perfectly clear to me that the 0.6ohm pod is designed for use with the airflow slider wide open for an RDL vape. Just don’t bother attempting any other style of vaping because it comes at a cost to flavour.

The flavour and vapour production was generally very good. Consider E-liquid ratios of 50/50, 65/35 or 70/30 when using this pod.

The 0.8ohm pod is specifically designed for a MTL vape. To get the very best experience, set the airflow slider to around mid position and you’ll be happy as Larry – or Letty.

The flavour and vapour production was excellent.

Consider E-liquid ratios of 50/50 when using this pod.

The main difference between the two pods is quite startling. The 0.6ohm pod tends to lose flavour impact as airflow is reduced. The 0.8ohm pod benefits from it.

So that shows the characteristics of each and in this respect, they do their job and deliver the goods.

I think the 0.8ohm pod edges it for me simply because of its overall performance across those airflow restrictions.

Oh. Nearly forgot to mention. You’ve heard of Easter eggs in movies. Now there’s Vaping eggs. Let me explain.

If I find something that’s not mentioned in the instructions, I’ll refer to them as Vaping eggs.

In this case it’s with the LED. While auto drawing, it displays a groovy spectrum of colours that constantly change. Cool, eh?

So overall, familiarity hasn’t bred contempt. The Vaporesso XROS 3 Nano isn’t a bad pod kit at all. As long as you realise that each pod is assigned a specific role. Use the 0.6ohm pod for RDL vaping and the 0.8ohm (under some restriction) for a MTL experience.

vaporesso-xros-3-nano-pod-kit-reviewThe simplest approach is always the best approach and Vaporesso knows this all too well. You really don't need to tinker much with the airflow slider to find a decent RDL or MTL vape. When you have got it right, the flavour and vapour production is pretty damn good.
