Product Description

If you know anything about pod vapes, then the chances are you know the XROS name.

Vaporesso now brings us the XROS 4 and 4 Mini. Both are incremental upgrades on the previous generation.

Both devices sport a 1000mAh battery, and adjustable airflow (an upgrade for the Mini).

The XROS 4 also comes with adjustable power with 3 levels.

Design & Build Quality

There’s not much to tell you about the designs of the XROSS 4 and 4 Mini because, honestly, not much has changed.

The 4 is still the taller of the two devices, measuring 120.8 mm compared to the aptly named Mini’s 107.5mm. Both have a width of 24mm and a depth of 14mm.

They are XROS devices and look and feel almost exactly the same as any other XROSS. Same curved edges and super comfortable grip in the hand.

The XROS 4 is taller, and the reason is that it features adjustable power and a physical fire button. More on this soon.

Vaporesso has been a little more daring with the colorways this time around. I’ve got the Pastel Pallete version of the 4.

It’s a pretty psychedelic color. It kind of reminds me of those ‘70s tie-dye T-shirts. I’m surprised I actually quite like it.

There are still the normal base style colors if you want to keep it simple.

Both devices have an adjustable airflow slider on the back. Which is a distinct upgrade for the Mini.

It’s the same airflow slider as the normal XROS 3s. But that doesn’t mean it delivers the same airflow, as I’ll cover later.

The USB-C port is located on the base of the 4 Mini and on the left side of the 4.

The 4, being the more premium model, comes with 2A fast charging, while the Mini is stuck in the past with 1A. Which is an unnecessary move, in my opinion.

But hey, I guess they have to find a way to differentiate between the two, so you opt for the more expensive one!

The Mini fools you into thinking it has a touch button on the front face. But it’s just the battery gauge panel. There’s a small LED in the center.

The 4 has a physical fire button to switch the device on/off, adjust the power, and manually fire – who does that nowadays?

It’s a really nice fire button. It’s curved, it’s clicky, it’s Vaporesso button.

There’s a glossy mirrored section around the fire button. This is where the power and battery indicators are hidden.

There’s colored LEDs that sit behind and shine through. It looks cool, but it’s not the brightest and is a little tricky to see in daylight – and take pictures of!

I know what you’re thinking. Why didn’t Vaporesso just include an LED screen and fully adjustable wattage?

That, my friends, is reserved for the XROS Pro. So that’s a further upgrade if you want it!

While the new XROS designs might only be incremental. At least the colorways have a bit more adventure to them. And the build quality of both devices is what we’ve come to expect from Vaporesso. It’s exceptional.


The XROS 4 and 4 Mini are a little varying when it comes to features. Here’s the rundown:

Both devices have an in-built 1000mAh battery.

The XROS 4 has 2A fast charging for the battery (30 minutes). The 4 Mini is double the time with only 1A – Ouch!

Both devices use Vaporesso’s AXON chipset.

However, the XROS 4 has variable power, with 3 output modes: Low, Medium, and High.

Vaporesso doesn’t state the wattage of each level (for different resistances). So it’s a bit of a guessing game.

Both devices have LED battery indicator lights with the following:

  • Green = 70-100%
  • Blue = 30-70%
  • Red = 0-30%

The XROS Mini’s LED is a small slither in the center of the device. Whereas the XROS 4 has a circular LED light, which doubles up as the power indicator.

The XROS 4 also has 3 little vapor symbols to show which power mode you have selected. Along with a ‘lock light’ indicator for when you lock the fire button.

Both devices use auto-draw firing. But the XROS 4 can also be fired manually with the button.

They both have adjustable airflow. This is a slider on the back that can cover a tight MTL to a restricted DL draw.

As you’d expect, both are compatible with the full range of XROS pods – covered in detail later.

And, of course, both XROS devices have all the safety you’d expect. So you are protected from overcharging, over-vaping, and all the other ‘overs’ you need to be protected from.

How to Use the XROS 4s

The XROS 4 Mini is one of the easiest pods to use. As there are no power settings or buttons.

It’s just as easy as attaching your pod; the power will get set based on the resistance of the pod. Then, you just use the auto-draw to start vaping.

There is no on/off for the 4 Mini.

The XROS 4 has a few settings to deal with, but it’s still so simple:

  • On/Off = 5 clicks of the fire button
  • Mode Settings = 2 clicks of the fire button (in 2 seconds). Each further click rotates through the 3 modes. Wait or vape to select.
  • Lock fire button = 3 clicks of the fire button (in 2 seconds).

Honestly, both are so easy that even a chimpanzee could use them.

I do not condone chimpanzees vaping!


The XROS 4 and 4 Mini are fully compatible with all the XROS range of pods.

The range now consists of three 3ml capacity pods:

  • 0.4Ω (25W)
  • 0.6Ω (21W)
  • 0.8Ω (16W)

And then there are five 2ml capacity pods:

  • 0.4Ω (25W)
  • 0.6Ω (21W)
  • 0.8Ω (16W)
  • 1.0Ω (12W)
  • 1.2Ω (10W)

Bizarrely, Vaporesso’s website marks the 0.4Ω pods as not available for sale in the US. This is even more baffling because they come in a 3ml capacity, which is not TPD compliant.

I’m sure it’s just a time thing, and they will be available in the US.

Either way, when you purchase the XROS 4 or 4 Mini, you seem to have the option to choose which resistance pods it comes with.

This might not be the case with every supplier, so do double-check.

The XROS 4 kit will include 2 pods, while the Mini will only include 1 pod.

We got the XROS 4 with a 0.4Ω, 0.6Ω and a 0.8Ω pod. Then, the Mini came with a 0.4Ω pod. All of them at 3ml capacity.

So, the rest of this review will be based on the performance of the included coils – with my added experience of previous XROS pods.

All the pods feature Vaporesso’s Corex 2.0 coil technology. They are also all top-fill with the snap-fill mechanism.

The top-fill is even included on the 3ml pods. This never used to be the case, as old 3ml XROS pods had a sidefill bung.

Another thing to note is I think the 2ml capacity pods give you ever so slightly better flavor – due to your mouth being closer to the coil.


Ok, so we know that the XROS pods and devices are among some of the best performers in the market.

So the real question is, how do the XROS 4s and the new pods compare to other XROS devices? And how do they stack up against the likes of the Caliburns, etc.?

Before I get into the key difference… pods. Let’s talk about airflow.

The biggest difference between these XROS 4s (compared to the 3s or even the Pro) is the smoothness of the airflow.

That’s not to say that the older devices had choppy airflow.

But Vaporesso seems to have tightened up something. The airflow now feels silkier, especially when in those tighter MTL ranges.

Other than that, the devices are pretty much on par with other XROS’. Delivering excellent battery life. Instant auto-draw response.

And perhaps most importantly, an easy-to-use vape experience.

The 3 power levels on the XROS 4 work. There’s definitely a difference when you switch modes.

I’m not the type of MTL vaper that needs full control of my wattage. Most of the time, these smart devices set the best wattage… and that’s good enough for me.

So, the 3 levels of the XROS 4. And even the take-it-as-it-comes of the Mini are perfect for MTL vaping with the MTL pods.

The 0.8Ω is an XROS pod that I have purchased and vaped hundreds of times. It just works.

It’s one of my favorites for a reason

It delivers excellent flavor. It’s consistent. And is great for all MTL airflows.

And that’s exactly what it does with both XROS 4s.

If I’m really honest, the Caliburn G3 might just edge it out for flavor. But you’d only really notice it comparing them side by side.

The 0.6Ω is another pod resistance I’ve used before and know well.

However, the sample one I received didn’t exactly set the world alight. In fact, it had a bit of a moment wicking and set the coil alight.

Ok, that’s just me being dramatic.

It gave me a bit of a burnt taste on my first inhale, and after that, I just couldn’t shake it. You know the feeling when every puff you take just feels a bit tainted. Yep, that was my experience with the 0.6Ω.

Before you ask. Yes, I gave it time to sit after filling it. And no, I didn’t use overly thick juice (it was only 70VG).

Now, from my experience, that’s an incredibly rare thing to happen with XROS pods. And the caveat here is that this was a sample pod (and clearly marked as a sample).

So, I guess it was just one of those things. I’ve got to be honest.

My experience with the new 0.4Ω pod couldn’t be more different. Wow, that thing just sings.

I don’t remember the 0.4Ω being this good with the XROS Pro. It just kept delivering awesome flavor, and smooth plentiful vapor.

All with the same juice I used in the 0.6Ω, I might add.

I’m on the same 0.4Ω after two weeks, and it’s still tasting like it’s brand new.

My only minor gripe is that it came included with the 4 Mini. While it does a great job here, I think it’s better suited to the 4, where you can up the power.

And, of course, even more suited to the XROS PRO, where you can go to town with the power.

Ok, so enough waffling.

Both devices are great. They are easy to use and deliver the quality vape Vaporesso is known for. The airflow is also marginally better.

The 0.8Ω, as always, is the go-to for MTL vaping. And the 0.4Ω is a banger for RDL.

Battery life is excellent with both getting you through a day of vaping, even with the 0.4Ω. However, the Mini loses points for only having 1A charging.

If you don’t mind waiting an hour for it to charge, and you’re an MTL vaper who’s not fussed about adjusting power. Then the Mini is more compact and would be my top choice.

If you’re looking for more control and faster charging, go for the larger XROS 4. For power-hungry control freaks, get the XROS Pro.


  • Sleek premium design
  • Excellent build quality
  • Easy to use
  • Outstanding flavor (all pods)
  • 3 Adjustable power modes (XROS 4)
  • Hidden OLED indicators
  • Flawless auto draw firing  
  • Top fill
  • Good lifespan of pods
  • Smooth Adjustable airflow (MTL to RDL)
  • Good battery life (1000mAh)
  • USB-C fast charging (XROS 4)
  • Compatible with all XROS pods


  • Power adjustment is a little limited
  • Only 1A charging on XROS 4 Mini


The XROS 4 and 4 Mini have both lived up to the XROS name. They delivered the performance I expected – which is outstanding.

They are easy to use, stylish devices, and deliver fantastic flavor from all the pods.

If you already own an XROS 3, the upgrade is probably not worth it unless you want to control the power output a bit.

If you’re looking to upgrade to the XROS 4 Mini from the 3 Mini, that’s an easier decision. If you are happy with the airflow, don’t. If you want fully adjustable airflow, do.

If you want more control and are more of a DL vaper, then go for the XROS PRO. The extra battery will serve you well.

It’s a testament to Vaporesso that the XROS range is always considered among the best. Yes, the XROS 4 will still take one of the top spots. But it is only marginally improved over the XROS 3.

Next time, they might need to take a bigger leap. As there are a lot of other exceptional pod vapes snapping at their heels.
