Key Features of the Vaporesso XROS 4 Mini
COREX 2.0 Mesh Coil Technology
The headline upgrade in the XROS 4 Mini is the inclusion of COREX 2.0, Vaporesso’s second-generation heat-distributing mesh coil system. Compared to the original COREX design, COREX 2.0 delivers improved vapour production, more accurate flavour reproduction, and a longer coil lifespan.
The mesh structure distributes heat evenly across the coil surface, which means faster ramp-up time, consistent temperature from the first puff to the last, and a noticeably cleaner taste profile. If flavour quality is your priority, COREX 2.0 is a genuine upgrade over standard coil designs found in comparable kits.
Adjustable Airflow for MTL and RDL Vaping
Unlike the XROS 3 Mini’s fixed airflow, the XROS 4 Mini features an adjustable airflow slider that lets you toggle between mouth to lung (MTL) and restricted direct to lung (RDL) vaping styles. Close the slider for a tighter, more cigarette-like draw. Open it up for a slightly airier, more voluminous inhale.
This single addition significantly expands who the device suits. It works for cautious first-time vapers who want a close cigarette substitute, and for more experienced users who prefer a looser draw with denser vapour.
Full Aluminium Unibody Design
The XROS 4 Mini is built from a purely aluminium unibody chassis, giving it a premium feel well above its price point. The material is lightweight, resistant to everyday wear and tear, and provides a comfortable grip that does not feel slippery or cheap. At 46.6g, it sits lightly in a pocket or hand without feeling insubstantial.
Available in 10 colourways including Black, Space Grey, Ice Blue, Ice Pink, Champagne Gold, and Camo variants, there is an option to suit most preferences.
RGB Battery Indicator
The XROS 4 Mini uses an RGB LED indicator to communicate battery status at a glance, removing any ambiguity about charge levels:
- Red light: 0% to 30% (charge soon)
- Blue light: 30% to 70% (mid-range)
- Green light: 70% to 100% (fully charged)
Simple, functional, and immediately readable in any lighting condition.
1000mAh Battery with USB Type-C Charging
The integrated 1000mAh battery provides all-day vaping capability under normal use, and the USB Type-C port ensures fast, convenient charging from any compatible cable. For a device this compact, the battery performance is strong and you are unlikely to find yourself scrambling for a charger mid-day.
Available Colours
The XROS 4 Mini comes in 10 colourways, giving you plenty of room to find one that suits your style. The range covers clean everyday tones as well as bolder, eye-catching finishes:
- Black
- Space Grey
- Ice Blue
- Ice Green
- Ice Purple
- Ice Pink
- Champagne Gold
- Camo Silver
- Camo Red
- Camo Yellow
The Ice variants have a frosted, translucent quality that catches the light well, while the Camo options bring a more textured, tactile finish. Black and Space Grey are the go-to choices for anyone who prefers something understated and versatile.
How to Use the Vaporesso XROS 4 Mini
Step 1: Charge fully before first use. Connect via the USB Type-C port and charge until the LED turns green.
Step 2: Fill the pod. Remove the pre-installed 0.4Ω XROS pod from the device. Open the top-fill port and slowly fill with your chosen nicotine salt or freebase e-liquid up to the 2ml capacity. Reseal the fill port firmly.
Step 3: Prime the coil. Wait 5 to 10 minutes after filling before vaping. This allows the e-liquid to saturate the COREX 2.0 mesh coil fully and prevents a burnt first draw.
Step 4: Reinsert the pod. Slide the pod back into the device until it clicks into place.
Step 5: Adjust your airflow. Use the slider on the side of the device to set your preferred draw resistance. Tighter for MTL, more open for RDL.
Step 6: Inhale to activate. The XROS 4 Mini is auto-draw with no buttons required. Simply inhale from the mouthpiece and the device fires automatically.
Step 7: Monitor the LED. Keep an eye on the RGB indicator and recharge when the light turns red.
Who Should Use the Vaporesso XROS 4 Mini?
The XROS 4 Mini is designed to be accessible to almost anyone, but it is particularly well-suited to a few specific groups of people.
Smokers looking to switch. This is arguably where the XROS 4 Mini earns its strongest recommendation. The MTL draw closely replicates the pull resistance of a traditional cigarette, which makes the transition feel natural rather than jarring. Nicotine salt e-liquids deliver a smooth throat hit at higher concentrations, closely matching the nicotine satisfaction of a cigarette without the combustion, tar, or carbon monoxide. If you have tried vaping before and found it unsatisfying, a proper MTL pod kit like this is a fundamentally different experience to a sub-ohm device.
Vapers who want to cut costs. Anyone spending regularly on disposable vapes will find the XROS 4 Mini a far more economical long-term option. A 10ml bottle of nicotine salt e-liquid costs a fraction of the equivalent puffs in disposable form, and replacement pods are inexpensive. The device itself pays for itself quickly.
People who want simplicity without compromise. There is a type of vaper who simply does not want to think about coil resistances, wattage settings, or device menus. The XROS 4 Mini is built for them. Auto-draw activation, automatic wattage adjustment, and a top-fill pod system mean there is almost no learning curve. You fill it, you vape it.
On-the-go and active lifestyles. At 46.6g and slim enough to fit in any pocket, the XROS 4 Mini suits people who are always moving. Whether you are commuting, travelling, or simply want something discreet for social situations, the compact form factor and modest vapour output make it one of the least intrusive devices available.
Is Vaping with the XROS 4 Mini Better Than Smoking?
Switching from cigarettes to a device like the XROS 4 Mini represents a significant step away from the most harmful aspects of tobacco use. Cigarettes produce smoke through combustion, which generates thousands of toxic chemicals including tar and carbon monoxide. Vaping heats e-liquid to produce vapour rather than smoke, eliminating combustion entirely.
Public Health England has previously concluded that vaping is substantially less harmful than smoking for adult smokers who switch completely. The XROS 4 Mini is particularly well-positioned as a switching tool because its MTL draw and nicotine salt compatibility allow smokers to replicate the physical experience of smoking closely enough that cravings are addressed effectively.
It is worth noting that vaping is not risk-free and is not recommended for non-smokers. However, for established adult smokers looking to move away from cigarettes, a well-designed pod kit like the XROS 4 Mini is one of the most practical and accessible tools available to support that transition.
Final Verdict
The Vaporesso XROS 4 Mini is a well-rounded upgrade over its predecessor, bringing genuine improvements in flavour technology, airflow flexibility, and build quality at the same accessible price. The COREX 2.0 mesh coil alone justifies the upgrade for anyone prioritising taste, while the adjustable airflow slider opens the device up to a wider range of vaping preferences.
At £17.99, it is one of the most complete MTL pod kits available in its price bracket.
Frequently Asked Questions About the Vaporesso XROS 4 Mini
How long does the Vaporesso XROS 4 Mini last? The 1000mAh integrated battery comfortably supports a full day of regular vaping. The exact duration depends on how frequently you vape and which pod resistance you use, but most users will not need to recharge mid-day under typical conditions. When the battery does run low, the RGB indicator turns red as an early warning, and the USB Type-C port charges the device quickly from any compatible cable.
Is XROS 4 Mini better than XROS 3? In most respects, yes. The XROS 4 Mini introduces three meaningful improvements over the XROS 3 Mini: the COREX 2.0 mesh coil delivers noticeably better flavour and a longer pod lifespan, the adjustable airflow slider allows you to switch between MTL and RDL vaping styles, and the full aluminium unibody chassis feels more refined and durable. Both devices share the same 1000mAh battery and £17.99 price point, so the XROS 4 Mini is the stronger choice for anyone buying new.
How much does a Vaporesso Mini cost? The Vaporesso XROS 4 Mini is priced at £17.99, making it one of the most affordable rechargeable pod kits on the market. Replacement XROS pods are available separately at a fraction of the cost of disposable vapes, which makes the long-term cost of ownership very competitive. If you are currently spending regularly on disposables, switching to the XROS 4 Mini will reduce your ongoing costs significantly.
How many watts is the Vaporesso XROS Mini 4? The Vaporesso XROS 4 Mini operates using the AXON smart chipset, which automatically adjusts power output based on the pod inserted. The device does not use a fixed single wattage setting. The pre-installed 0.4Ω XROS pod is designed for a warmer, more voluminous draw, while higher resistance pods such as the 1.0Ω and 1.2Ω options run at lower output for a cooler, tighter MTL experience. The auto wattage system handles all of this without any manual input required.
