The Vaporesso XROS range is one of the most popular pod vape families in the UK, but the names can be confusing. XROS 3, XROS 4, XROS 5, XROS 6, then Mini, Nano and Pro on top. This guide explains what each one means, so you can compare Vaporesso XROS pod kits and pick the right one without guessing.
Short answer: the number is the generation, and newer generations replace older ones. In the current range, Mini means a small, simple inhale-activated kit, Nano means a very compact kit that also has a button, and Pro means adjustable power. For most people, an XROS 5 Mini or XROS 6 Mini is the easy starting point, and an XROS Pro 2 is the step up.
What is the Vaporesso XROS series?
The Vaporesso XROS series is a family of slim, refillable pod kits. Each kit has a rechargeable battery and a 2ml pod with the coil built in. You fill the pod, click it in and vape. When the flavour fades, you swap the whole pod, so there is no coil to build or change.
Most Vaporesso XROS kits are made for mouth-to-lung vaping, which is a slow, tight draw similar to smoking a cigarette. That is why they suit nic salt and 50/50 e-liquid.
XROS 3, 4, 5 and 6: what the numbers mean
The number is the generation. XROS 5 replaces XROS 3 and XROS 4, and XROS 6 is the newest.
- XROS 3 and XROS 4: older generations that are being phased out. You can still find their pods, but newer kits have replaced them.
- XROS 5: 1500mAh battery, up to 30W, with both button and inhale firing.
- XROS 6: the newest generation. The XROS 6 Mini uses a 1600mAh battery and the newer Corex 3.0 pod.
Vaporesso XROS Mini, Nano and Pro compared
After the number comes the size or feature level. This is how the names break down.
XROS 3 Mini and XROS 4 Mini
The XROS 3 Mini and XROS 4 Mini are the older small kits. Both have a 1000mAh battery, a 2ml pod and inhale-activated firing, so there are no buttons or menus. They are simple and light, but the battery is the smallest in the range, and they are being replaced by the newer Mini kits.
XROS 5 Mini and XROS 6 Mini
The XROS 5 Mini and XROS 6 Mini are the current small kits. Both are inhale-activated and run up to 30W. The XROS 5 Mini has a 1500mAh battery. The XROS 6 Mini has 1600mAh, a 2ml Corex 3.0 top-fill pod with a 0.6Ω coil, and USB-C charging. The XROS 6 Mini also takes other XROS pods, so you are not locked into one pod type.
XROS 5 Nano
The XROS 5 Nano is a very compact kit with a 1600mAh battery and up to 30W. Unlike the Mini kits, it has both button and inhale firing, so you choose how you vape.
XROS Pro and XROS Pro 2
The XROS Pro is the adjustable version, with power up to 30W. The XROS Pro 2 takes that further with a 2000mAh battery, power from 5W to 30W and button or inhale firing. It also takes the lower-resistance 0.4Ω and 0.6Ω pods, which suits a looser draw. If you like to tune your vape, XROS Pro is the one to look at.

Which XROS pod kit should you buy?
- XROS 5 Mini or XROS 6 Mini: best for first-time switchers who want a simple, no-button kit. Skip if you want to adjust the power.
- XROS 5 Nano: best for the smallest kit that still has a button. Skip if you want a bigger battery.
- XROS 5: best for a standard-size kit with button and inhale firing. Skip if you want adjustable wattage.
- XROS Pro 2: best for adjustable power and the biggest battery in the range. Skip if you want the smallest possible device.
- XROS 3 Mini or XROS 4 Mini: only worth it if you already have the pods. Skip if you want a current model.
XROS pods and e-liquid
XROS pods fit XROS kits, and most work across the whole Vaporesso XROS range. The exception is the low-resistance 0.4Ω and 0.5Ω pods, which only work in XROS 4, XROS 5, XROS 6 and XROS Pro generation kits. They will not work in an XROS 3 Mini.
Pods from 0.5Ω to 1.2Ω are made for e-liquid with 50% PG or more, which covers 50/50 e-liquid and most nic salts. The 0.4Ω pod is made for high-VG e-liquid of 70% VG or more. UK nicotine e-liquid is capped at 20mg/ml and sold in bottles of 10ml or less. As a rough guide, 10mg suits someone who smoked under 10 cigarettes a day and 20mg suits someone who smoked 20 or more. Nicotine is addictive, so choose the lowest strength that works for you.
Frequently asked questions
Can you swap pods between XROS kits?
Mostly yes. Standard XROS pods fit across the range. Check the resistance, because the 0.4Ω and 0.5Ω pods need an XROS 4, 5, 6 or Pro generation kit.
Which Vaporesso XROS is best for beginners?
The XROS 5 Mini or XROS 6 Mini. They are small, inhale-activated and easy to use, with nothing to adjust.
How long does an XROS pod last?
Typically about a week with regular use, and longer with light use. Very sweet e-liquids wear a coil out faster, so swap the pod when the flavour drops.
Are the XROS 3 and XROS 4 still worth buying?
They are older generations being replaced by XROS 5 and 6. Their pods are still easy to find, but a newer kit gives you a bigger battery and a better pod.
Final thoughts
Choosing a Vaporesso XROS comes down to three things: the generation number, the size (Mini, Nano or Pro), and the pod resistance. Start with an XROS 5 Mini or XROS 6 Mini if you want simple, and move to the XROS Pro 2 if you want control.
