The Vaporesso XROS is one of the best-selling refillable pod kits in the UK, and over the years it has grown into a whole family: the XROS 3 Mini, 4 Mini, XROS 4, XROS 5, XROS 6 and XROS Pro. They look similar, they share pods, and the prices are close together, so choosing between them is not obvious. This guide compares every XROS kit we stock, explains what changed between models, and helps you pick the right one.
The XROS range at a glance
| Kit | Price | Battery | Key feature |
|---|---|---|---|
| XROS 3 Mini | £12.99 | 1000mAh | Simplest and cheapest |
| XROS 4 Mini | £13.99 | 1000mAh | COREX 2.0 heating for better flavour |
| XROS 4 | £18.99 | 1000mAh | AXON chip, adjustable power and airflow |
| XROS 5 | £18.99 | 1500mAh | COREX 3.0, up to 30W, 3A fast charging |
| XROS Pro | £19.99 | 1200mAh | Up to 30W, 0.4 ohm pod, slide lock |
| XROS 6 | £20.99 | 1800mAh | Biggest battery in the range |
XROS 3 Mini
The Vaporesso XROS 3 Mini is the entry point at £12.99. It is a simple, draw-activated pod kit with a 1000mAh battery: no buttons, no settings, just fill and vape. It is ideal if you are moving from a pre-filled kit and want the cheapest way into refillable vaping.
XROS 4 Mini
The Vaporesso XROS 4 Mini costs just £1 more and adds Vaporesso’s COREX 2.0 heating technology, which is designed to heat the coil more evenly for richer flavour. If you are buying a Mini, this is usually the one to pick.
XROS 4
The Vaporesso XROS 4 is the first “full-size” model on this list. Its AXON chip gives you adjustable power and it has adjustable airflow, so you can fine-tune the draw from tight to more open. It suits vapers who want a little more control than the Mini kits offer.
XROS 5
The Vaporesso XROS 5 is a big step up in battery and power: 1500mAh, up to 30W and COREX 3.0 heating, with 3A fast charging so it is back to full quickly. At the same price as the XROS 4, it is one of the best-value kits in the range.
XROS Pro
The Vaporesso XROS Pro is the more powerful, more rugged option. It has a 1200mAh battery, up to 30W, a 0.4 ohm pod for a looser, warmer vape, and a slide lock to stop it firing in your pocket. It suits people who like a restricted direct-lung draw.
XROS 6
The Vaporesso XROS 6 is the newest model, with the largest battery in the range at 1800mAh. If battery life matters most to you, this is the one. We cover it in depth in our Vaporesso XROS 6 guide.
XROS pods: do they all fit?
One of the best things about the range is that XROS pods are broadly cross-compatible, so you can usually keep using the same pods when you upgrade. The XROS Series COREX 2.0 pods are a good all-round choice. Pods come in different resistances: higher (around 0.8 to 1.2 ohm) for mouth-to-lung, lower (around 0.4 to 0.6 ohm) for a looser draw. Always check the product page to confirm a pod fits your model.
Which XROS should you buy?
| If you want… | Choose |
|---|---|
| The cheapest refillable kit | XROS 3 Mini |
| Simple, but with better flavour | XROS 4 Mini |
| Adjustable power and airflow | XROS 4 |
| Best value for battery and power | XROS 5 |
| A looser, warmer draw | XROS Pro |
| The longest battery life | XROS 6 |
What changed between generations?
Vaporesso has refined the XROS steadily rather than reinventing it, which is why the models look so alike. The main changes over time have been:
- Heating technology. COREX 2.0 and then COREX 3.0 aim to heat the coil more evenly, giving fuller flavour and helping pods last longer.
- Battery size. From 1000mAh on the Minis and XROS 4, to 1500mAh on the XROS 5 and 1800mAh on the XROS 6.
- Power control. The Minis are fixed and simple; the XROS 4 onwards let you adjust power, with the XROS 5 and Pro reaching 30W.
- Charging speed. The XROS 5’s 3A fast charging means far less time waiting at the socket.
If you already own an older XROS and it still works well, there is no urgent need to upgrade. The biggest real-world gains are battery life and flavour, so upgrade if either has been bothering you.
Mouth-to-lung or restricted direct-lung?
Most XROS kits are built for mouth-to-lung (MTL) vaping: you draw vapour into your mouth first, like a cigarette. This suits higher-resistance pods and nic salts, and is what most people switching from smoking prefer. The XROS Pro and the higher-power settings on the XROS 5 open up a restricted direct-lung (RDL) style: a looser draw straight to the lungs, with more vapour, best with a lower-resistance pod and a lower nicotine strength.

Getting the best flavour from an XROS
- Prime new pods. Fill the pod and wait five minutes before your first puff so the cotton soaks fully.
- Do not overfill. Stay under the maximum line to avoid leaks. See How to Fill a Pod Kit.
- Use the right liquid. 50/50 or nic salt works best. Thick 70/30 liquid can cause dry hits in high-resistance pods. For liquid ideas, read Best Shortfills UK.
- Keep power sensible. On adjustable models, start low and raise it gradually.
- Change pods when flavour fades, usually every one to two weeks. See Why Does My Vape Taste Burnt?
XROS vs other popular pod kits
The XROS’s main rivals are the OXVA Xlim and the Voopoo Argus. The Xlim range is similarly slim and flavour-focused; we compare them directly in Vaporesso XROS vs OXVA Xlim. The Argus range offers more power at the top end, especially the Argus Pro 2; see Voopoo Argus Range Compared. For first-time buyers weighing up every option, Best Vape Kits for Beginners UK is the place to start.
Caring for your XROS battery
Charge with the USB-C cable supplied or a good-quality one, avoid leaving it charging overnight, and keep it away from extreme heat. Topping up when the battery indicator turns low, rather than running it completely flat every time, helps keep it healthy for longer. More in Vape Battery Tips.
Frequently asked questions
Which XROS is best for beginners?
The XROS 4 Mini. It is cheap, simple and has better flavour than the 3 Mini for only £1 more.
Can I use nic salts in an XROS?
Yes. XROS kits are designed for nic salts and 50/50 liquids, especially with higher-resistance pods.
Are XROS kits legal in the UK?
Yes. They are rechargeable and refillable, so they are not affected by the disposable vape ban.
Do XROS pods fit every XROS kit?
XROS pods are broadly cross-compatible across the range, which makes upgrading easy. Still, check the product page for your exact model before buying, especially for newer pod versions.
How long does an XROS pod last?
For a typical vaper, around one to two weeks. Very sweet liquids and high power shorten that, while gentle puffs and steady charging help pods last longer.
Which XROS has the best battery life?
The XROS 6, with an 1800mAh battery. The XROS 5 is next at 1500mAh and adds fast charging.
Why is my XROS flashing?
Usually the battery is low or the pod is not connecting. Charge it, then remove the pod, wipe the contacts dry and click it back in firmly. If the light keeps flashing with a new pod fitted, the pod may be faulty.
Is the XROS 5 or XROS 6 better?
The XROS 6 has the larger battery. The XROS 5 is a little cheaper, has COREX 3.0 and 3A fast charging, and offers up to 30W. Choose the 6 for battery life, the 5 for value.
Is the XROS Pro worth the extra?
If you like a looser, warmer draw, yes: the 0.4 ohm pod and 30W output are made for that. If you prefer a tight, cigarette-like draw, the XROS 4 Mini or XROS 5 will suit you better and cost less or the same.
Can I vape shortfills in an XROS?
Yes, choose a 50/50 pod-friendly shortfill and add a nic shot. Thicker 70/30 liquids may struggle to wick in higher-resistance XROS pods.
Do XROS kits have a child lock?
The XROS Pro has a slide lock to stop accidental firing. Always store any vape kit and e-liquid well out of reach of children.
Where should a first-time buyer start?
With the XROS 4 Mini and a pack of COREX 2.0 pods. It is simple, cheap and easy to upgrade from later.
The bottom line
Every XROS is a solid choice. The Minis are the value picks, the XROS 5 is the best all-rounder for the money, the Pro suits looser draws, and the XROS 6 wins on battery. Browse the full Vaporesso range.
