Vaporesso XROS Comparison: Which XROS Kit Should You Buy?

If you want a refillable pod kit you can grow into, the Vaporesso XROS range is one of the easiest places to start. The difficulty is choosing between the models. The range runs from the screen-free XROS 3 Mini to the XROS 6 with its new VENTURI airflow, and every model uses the same family of XROS pods. What actually separates them is battery size, whether there is a screen and button, and how much control you get over power and airflow.

This Vaporesso XROS comparison sets out the verified specifications for each kit, explains what the numbers mean in day-to-day use, and covers pod compatibility, UK rules on pod size and the new vaping duty, so you can match a kit to the way you vape.

How the Vaporesso XROS Range Works

The Vaporesso XROS is a family of refillable pod kits designed mainly for mouth-to-lung (MTL) vaping, with later models also handling a looser restricted direct-to-lung (RDL) draw. You fill a pod with e-liquid, click it into the device magnetically, and replace the pod when the flavour starts to fade.

Vaporesso has kept the same pod format across generations. That is the range's biggest practical advantage: if you move from an XROS 3 to an XROS 6, your spare pods usually come with you. Newer kits ship with COREX 3.0 mesh pods, while earlier kits used COREX 2.0, and reviewers report the newer pods are backwards compatible with older XROS devices.

What changes between generations?

Mostly the battery and the controls. The XROS 3 and XROS 4 generations use 1000mAh batteries. The XROS 5 moved to 1500mAh with fast USB-C charging, and the XROS 6 steps up again to 1800mAh. Each generation also has a "Mini" version that drops the screen and button to keep things simple.

Vaporesso XROS Comparison Table

The table below covers the XROS kits we stock. Battery figures come from manufacturer and retailer specifications. Kit contents can vary between UK and international versions, so check the product page for the exact pods in the box.

Battery capacity is the clearest predictor of how often you will charge. Real battery life depends on your wattage, pod resistance and how often you vape, so treat any "days per charge" claim as an estimate rather than a promise.

The Current Generation: XROS 6 and XROS 6 Mini

Vaporesso XROS 6

The XROS 6 is Vaporesso's full-size XROS for 2026. It pairs an 1800mAh battery with a 0.88-inch colour screen, button or draw activation and output up to 30W. Its headline change is the VENTURI airflow system, which Vaporesso says shapes the airflow for a smoother, denser draw. The kit comes with two COREX 3.0 pods in different resistances, so you can try a tighter and a slightly looser draw without buying extra pods.

Vaporesso XROS 6 Mini

The XROS 6 Mini removes the screen and button but keeps a lot of control. It has a 1600mAh battery, adjustable airflow and two power modes (ECO and POWER), switched by inhaling twice quickly. A hidden LED shows the battery level. One 0.6Ω pod is included. For anyone who wants the newest XROS without menus, this is the one to look at.

The XROS 5 Family: Still a Strong All-Rounder

The XROS 5 brought the biggest battery jump in XROS history, from 1000mAh on the XROS 4 to 1500mAh. It has a 0.88-inch colour display, adjustable output from 5W to 30W and 3A USB-C fast charging. It ships with 0.6Ω and 0.8Ω pods.

The XROS 5 Mini uses the same 1500mAh battery in a shorter body with no screen or button. You simply fill it and inhale, and a slider on the back sets the airflow. If you do not need to adjust wattage, the Mini covers most of what the full-size kit does.

XROS 6 vs XROS 5: is the upgrade worth it?

The XROS 6 adds 300mAh of battery and VENTURI airflow. Both share the same screen size and the same pod family. If you already own an XROS 5 and are happy with it, there is no pressing reason to change. If you are buying your first XROS today, the XROS 6 gives you the newer airflow and longer battery for a small price difference.

The Pro Models: XROS Pro and XROS Pro 2

The Pro line is aimed at vapers who want more power control. The original XROS Pro was the first XROS to use the 0.4Ω mesh pod with adjustable power up to 30W, along with a 1200mAh battery and Vaporesso's Super Pulse feature.

The XROS Pro 2 raises the battery to 2000mAh, the largest of any current XROS kit. If you vape heavily or simply hate charging, it is the obvious pick. The trade-off is a slightly larger device than the Mini models.

Older and Budget Models: XROS 4, XROS 3 and Mini Retro

The XROS 4 and XROS 4 Mini both use 1000mAh batteries. The XROS 4 adds a small screen, a fire button and three output modes, while the 4 Mini is draw-activated with no screen.

The XROS 3 was the first XROS with adjustable airflow, which made an RDL-style draw possible on the range for the first time. It has a 1000mAh battery and an LED light indicator. The XROS 3 Mini keeps the same battery in a simpler, draw-only body and is usually the lowest-priced way into the range.

The XROS Mini Retro is a compact 1000mAh, 18W kit with retro styling and inhale activation. UK stockists list it as taking every XROS pod except the 0.4Ω version.

Vaporesso XROS Pod Compatibility

XROS pods are designed to work across the whole series, which is why the range is popular with people who change kits often. Our Vaporesso XROS replacement pods come in five resistances, and each one suits a different draw:

• 1.2Ω and 1.0Ω: the tightest MTL draw and the most economical on battery.
• 0.8Ω: a slightly warmer MTL vape, and the standard in many kits.
• 0.6Ω: a looser draw with more vapour, often the pre-installed pod.
• 0.4Ω: designed for RDL vaping at higher power on kits with adjustable wattage, such as the XROS Pro, Pro 2, XROS 5 and XROS 6.

Why are UK XROS pods 2ml?

UK law limits e-cigarette tanks to 2ml and nicotine-containing e-liquid to 20mg/ml, under the Tobacco and Related Products Regulations 2016 as explained by the MHRA on GOV.UK. International reviews often list 3ml XROS pods, but UK versions hold 2ml. Pod size has no effect on compatibility.

Which e-liquid works best in an XROS?

Low-resistance MTL pods like these generally suit 50/50 e-liquids and nic salt e-liquids. Thick, high-VG liquids can wick slowly in small MTL coils. If you are unsure which strength to choose, our guide on choosing your e-liquid nicotine level explains the options.

Which XROS Should You Choose?

Rather than looking for a single "best" XROS, it helps to start from what matters most to you:

• You want the longest time between charges: XROS Pro 2, then XROS 6.
• You want a screen and adjustable power: XROS 6 or XROS 5.
• You want no buttons or menus: XROS 6 Mini or XROS 5 Mini.
• You want a low-cost starter kit or backup device: XROS 3 Mini, XROS 4 Mini or Mini Retro.
• You want to try RDL vaping: a kit with adjustable wattage plus the 0.4Ω pod.

UK Rules That Affect XROS Owners in 2026

Are XROS kits legal after the disposable vape ban?

Yes. The ban on single-use vapes that began on 1 June 2025 applies to devices that cannot be recharged, refilled and fitted with a replacement coil or pod. XROS kits are rechargeable, refillable and use replaceable pods, so they remain legal to sell. If you are moving away from disposables, our guide to long-lasting alternatives after the UK ban covers the main options.

How does the new vaping duty affect XROS users?

Vaping Products Duty started on 1 October 2026 at a flat £2.20 per 10ml of vaping liquid, whether or not it contains nicotine. The duty is charged on liquid, so it shows up mainly in the cost of e-liquid rather than in empty refillable pods. From 1 April 2027, all vaping products sold in the UK must carry a duty stamp. Full details are on GOV.UK.

How should I dispose of an old XROS?

XROS devices contain lithium batteries, so they should never go in household bins. Take used devices and pods to an electrical recycling point. You can find your nearest one on the Recycle Your Electricals website.

Frequently Asked Questions

Do all XROS pods fit all XROS kits?

Almost all of them. Vaporesso designs XROS pods to fit across the series, so COREX 2.0 and COREX 3.0 pods work in older and newer kits. The main reported exception is the XROS Mini Retro, which is listed as not supporting the 0.4Ω pod.

What is the difference between the XROS 6 and the XROS 6 Mini?

The XROS 6 has a larger 1800mAh battery, a colour screen, a fire button and adjustable wattage. The XROS 6 Mini has a 1600mAh battery, no screen and fires when you inhale, with two power modes instead of full wattage control.

Which Vaporesso XROS has the biggest battery?

The XROS Pro 2 has the biggest battery in the current range at 2000mAh. The XROS 6 follows at 1800mAh, then the XROS 6 Mini at 1600mAh.

How long does an XROS pod last?

There is no fixed lifespan. Pod life depends on the e-liquid, how sweet it is, the wattage and how much you vape. Replace the pod when the flavour turns muted or you notice a burnt taste, even if it still produces vapour.

Can I use the 0.4Ω pod in any XROS?

The 0.4Ω pod is intended for kits with adjustable power, such as the XROS Pro, Pro 2, XROS 5 and XROS 6. Check your kit's manual before using it in a Mini model, and avoid it in the Mini Retro.

Is the XROS good for mouth-to-lung vaping?

Yes. MTL vaping is what the XROS range was designed around. Higher-resistance pods (0.8Ω to 1.2Ω) with the airflow closed down give the tightest draw. Most kits from the XROS 3 onwards also have adjustable airflow for a looser draw.

Why is my XROS pod leaking?

Leaks usually come from overfilling, a damaged seal, or storing the kit in heat or at altitude. Fill to just below the top line, close the fill cap fully and wipe the contacts dry. If a pod keeps leaking after that, replace it.

How do I prime a new XROS pod?

After filling, leave the pod to stand for about five to ten minutes so the cotton soaks fully before you vape. Start on a lower power setting where your kit has one. The XROS 6 adds a guided priming timer for this step.

Can I charge my XROS with a phone charger?

All current XROS kits charge through USB-C, so a standard USB-C cable works. Use a reputable charger, avoid leaving the device charging unattended overnight, and stop using any device that gets unusually hot.

Final Verdict

The XROS range is more alike than its long model list suggests. Every kit takes XROS pods, all are refillable and legal to sell in the UK, and most of the differences come down to battery size and controls. The XROS 6 is the most up-to-date full-size option, the XROS Pro 2 suits anyone who wants maximum battery life, and the XROS 6 Mini and 5 Mini are the simplest picks for a fill-and-vape routine. The older 1000mAh models remain sensible as budget or backup kits. Before you buy, decide whether you want a screen and adjustable power, then compare the full Vaporesso pod kit range on battery size.
