Vaporesso XROS 4 Review

The latest additions to the XROS range are the Vaporesso XROS 4 and the XROS 4 Mini.

XROS 4 Mini and XROS 4

Vaporesso’s XROS brand has become one of the most recognisable names when it comes to pod kits.

We will be having a look at the XROS 4 in this review!

Earlier in the year, we reviewed the Vaporesso XROS Pro to great acclaim and it is a pod system I am still using to this day!

We’ve also taken a look at Vaporesso’s first range of e-liquid, Deliciu and also the Coss Click range of disposables that they recently released.

Vaporesso have been committed to delivering quality products over the years. This has been recognised with multiple awards globally – in fact over 130 awards to date!

Many thanks to Vaporesso for sending the XROS 4 in for review!

Will the XROS 4 follow in the footsteps of the XROS Pro? Let’s dive in and have a look…

What Can We Expect From The Vaporesso XROS 4?
The Vaporesso XROS 4 is a pod system that offers a simple, user-friendly experience.

It has 3 power output modes plus true Mouth To Lung (MTL) and Restricted Direct Lung (RDL) vaping. We tell you what these terms mean in our Guide To Vape Styles.

This is compatible with the full range of XROS pods, aside from the ones specifically designed for the XROS Pro.

The included 0.4ohm XROS pod features upgraded COREX 2.0 technology! This upgraded COREX 2.0 technology builds on the original and offers increased flavour and vapour production, with an even better pod lifespan!

Refined adjustments to the mesh grid within the coil ensures that the temperature matching is optimised. Which enables faster coil heating and even better taste. The cotton within the coil has also been upgraded, to make for better wicking and prevention of burnt hits.

An easy top filling system is found on the XROS pods. These have a 2ml capacity in TPD regulated areas and a 3ml capacity outside of this.

AXON pulse technology means that power is consistently boosted by the chipset. This ensures you have a regular and consistent vaping experience regardless of the current battery level. So your first puff should taste just as good as the last one!

There’s three power modes to choose from on the XROS 4 to suit your preferred style of vaping. It is easy to switch between the three different settings with single button operation.

A 1000mAh battery is built into the device, which fast charges in just 30 minutes via USB Type C.

An airflow adjustment slider on the XROS 4 makes fine tuning the airflow simple.

There are ten different colour options available at launch: Black, Silver, Blue, Green, Lilac Purple, Sunset Neon, Pink Mint, Champagne Gold, Pastel Palette and Bloody Mary.

XROS 4 Mini Overview
Alongside the XROS 4, Vaporesso are also releasing the XROS 4 Mini, which offers an even simpler vaping experience in a smaller package.

This also is compatible with the same range of XROS pods, taking advantage of that sweet COREX 2.0 technology and has an easy auto-draw system.

Adjustable airflow is also included, along with the same built in 1000mAh battery. Also a practical battery level indicator is also found on the device.

Design & Build Quality
I received the Purple and Bloody Mary colour options for review. Let me tell you – these are definitely lookers! The colours really stand out and make for a very attractive looking pod system.

The build quality is rock solid, these really do feel robustly made. The XROS 4 features an all Aluminium Alloy unibody design and this really looks and feels like a premium product.

It measures in at 120.8mm x 24mm x 14mm, making it actually a touch taller than the XROS Pro, but it is slightly thinner and feels lighter too.

It has smooth rounded edges which sit nicely in hand making it comfortable to hold and to operate.

A magnetic connection is used for the XROS pods, which connect with a satisfying click and are held in place nicely. A large viewing window is present on the pods, allowing you to easily check the e-liquid level and an easy to use top filling system is present.

On the body of the XROS 4 device is an LED display, which shows the current battery level, selected power output and has the power button at the bottom of the screen.

On the opposite side is the airflow adjustment slider, which features smooth travel and enables easy adjustment of the airflow on the fly.

There’s also a USB-C charging port located on the side of the XROS 4.

Quick Start Guide

How To Fill The XROS 4 Pod
Firstly, you’ll want to fill up the pod, to do so simply:

·Pop off the Black mouthpiece from the top of the pod
·Locate the Red filling port
·Stick the bottle nozzle into the filling port and fill it up.

After doing this, replace the mouthpiece and let the e-liquid sit in the pod for at least five minutes to allow the e-liquid to fully saturate the cotton. This will reduce the risk of dry hits and prolong the lifespan of the pods.

Next up, click the power button five times to turn the XROS 4 on. The screen should light up and cycle through a few different LED colours.

Airflow can be adjusted by simply popping your thumb on the airflow slider and sliding it right to close the airflow down, and left to open it up.

To cycle through the three different power settings, click the power button twice in two seconds to change the setting.

I’m no fan of fire buttons on pod systems, so after selecting my preferred power setting I locked it immediately by clicking the power button three times in two seconds!

If you haven’t locked the fire button, you can hold it down to fire the XROS 4, or simply take a draw on it. Auto draw mode will still be available regardless of whether the power button is locked.

Battery level is indicated via a coloured LED on the screen, Green means that there is 70-100% charge left, Blue is 30-70% and Red is 30%.

2A fast charging is supported by the XROS 4 meaning that you can get a full charge in just 30 minutes via USB-C.

A USB-C cable is included in the box, which slots into the charging port on the side of the device.

How Does The Vaporesso XROS 4 Perform?
You have a 0.4ohm XROS pod and a 0.8ohm XROS pod included in the kit, with the 0.4ohm pod boasting the upgraded COREX 2.0 technology.

Interestingly the Bloody Mary kit that I received for review actually featured a 0.6ohm XROS pod as well as the 0.8ohm one… But when I look online I can only see this being sold with the 0.4ohm and 0.8ohm pods, go figure!

I received the 3ml XROS pod editions for review, but these will have a 2ml capacity if purchased within a region covered by the Tobacco Products Directive, such as the UK.

Having previously tried out the 0.4ohm XROS pods with the XROS Pro, which are designed for restricted direct lung vaping, I was blown away with how good the performance of these were, with market leading performance in the flavour and vapour department.

And this is no different here, that same absolutely outstanding flavour delivery is very much present and correct!

These really do get the absolute most out of your e-liquids, allowing you to really enjoy all the flavour notes present in them and massively punch above their weight for a pod!

I hadn’t tried out the 0.6ohm pods before but I was very pleased with the performance of these as well.

Like the 0.4ohm pods, they are best suited for restricted direct lung vaping, offering a slightly cooler and less intense vape than the 0.4ohm pod but still packing plenty in the flavour and vapour departments.

The 0.8ohm coil is suited to a loose mouth to lung draw, so you’ll want to dial down the airflow when using this one. Flavour is still very good with this pod but the 0.4ohm and 0.6ohm versions win out for me here, as they are more suited to my style of vaping.

The 0.4ohm and 0.6ohm pods are pretty thirsty when it comes to e-liquid, I could easily refill one of these three times a day!

I also don’t have any issues with leaks from them either, aside from a very small bit of condensation build up at the base that I need to wipe away from time to time.

Lifespan is excellent, I’ve been using these pods daily for over the past week and they are still going strong with no degradation of flavour.

Adjusting the airflow gives you the option of a loose restricted lung hit when set fully open. Right down to a tight mouth to lung draw when closed down, with everything in-between.

The XROS 4 can kick out some pretty decent clouds with the airflow wide open.

Mod Performance
As well as adjusting the airflow, you can select from three different power output settings. To be honest I just stuck with the most powerful setting and left it at that as I found the other two settings too weak for my style of vaping. I quite enjoy a powerful vape!

Built into the XROS 4 is a 1000mAh battery, which will struggle to last a day with heavy usage. Fast charging is a bonus, but I’ve found that I have needed to take this out alongside another device if I’m going to be spending a while away from a plug socket!

·Outstanding flavour from the XROS pods
·Solid build quality
·Rock solid construction
·Great looks
·2A fast charging is pretty rapid
·Mouth to lung and restricted direct lung hit options
·Lots of different pod options available in the XROS range

·Screen is hard to see in daylight and bright light conditions
·No way to finely adjust the wattage output
·Battery doesn’t quite last all day
·0.4ohm XROS pod is pretty thirsty

Final Verdict
If you have read my Vaporesso XROS Pro review, you will know that I was a big fan of that, so I was really keen to try out the XROS 4.

And I’ve been left really impressed by this great bit of kit. You get absolutely excellent flavour from the XROS pods! Honestly amongst the absolute best in the pod market at the moment and they don’t slouch when it comes to kicking out the vapour too.

Build quality is absolutely great and there’s a wide range of different colours to pick from. The screen is bold and clear – as long as you aren’t in bright light!

It certainly won’t supplant my XROS Pro, but it will be an absolutely rock solid back up to it.

I can see this being a great option for people that are looking for a top performing pod system as a back up to their main device. Or for someone that just wants a very simple pod system that vapes fantastically well.

I would certainly recommend switching to something like this if you are still using disposable vapes!

If you don’t want to muck around with adjusting the power output and want a really simple plug and play option that has compatibility with the same excellent XROS pods at a cheaper price, then it is also worth considering the Vaporesso XROS 4 Mini.


A cut down version of the excellent Vaporesso XROS Pro that still offers phenomenal performance from the XROS pods!
