Pick up both of these kits in a shop and the choice feels harder than it should. They are roughly the same size, roughly the same price bracket, both top out at 30W, and both take refillable pods filled with the same kind of nic salt liquid. Yet they are built for different kinds of vapers, and that difference only shows up after a week of daily use, not at the counter.
The short answer before the detail
If you want the longest gap between charges and the fastest top up, buy the Vaporesso XROS 5. Its 1500mAh battery and 3A charging are the clearest practical advantages in this whole comparison, and they matter every single day.
If you want more control over your vape, buy the OXVA Xlim Pro 2. Its fully adjustable 5 to 30W output lets you warm up or cool down a flavour in a way the XROS 5, with its three preset power modes, simply does not. You also get a more tactile, dressed up device, with a zinc alloy body and a leather style grip panel.
For a first time switcher, the XROS 5 is the safer recommendation. For a vaper who likes tweaking wattage, the Xlim Pro 2 is more rewarding.
Specs at a glance
Both kits are mouth to lung and restricted direct to lung devices, which means they are made for a cigarette style draw or a slightly looser, airier draw, not for big cloud chasing. Both use USB-C charging, both fire by button or by simply inhaling, and both ship with a 0.6 ohm pod and a 0.8 ohm pod in the box. The differences are in the details, and the table below makes them easy to compare.

One note on pod capacity before we go further: UK and EU versions of both kits are capped at 2ml by regulation. If you see a 3ml figure for the XROS 5, that is the non UK version, not the one you will buy from a UK shop. In practice, for a UK buyer, pod size is a tie.
Design: dressed up versus clean and simple
The Xlim Pro 2 is the better looking device, and it is not particularly close. The zinc alloy frame feels solid, the leather style panel gives your fingers something to hold on to, and the small colour screen with its animated themes makes the whole kit feel like a piece of tech rather than a plain stick. It comes in a very wide range of colours and finishes, from carbon and python textures to bright solid colours. For a deeper look at the OXVA on its own, read the OXVA Xlim Pro 2 review.
The XROS 5 takes the opposite approach. Its aluminium alloy body is slimmer and plainer, with clean lines and a much larger 0.88 inch screen that is easier to read at a glance. It offers six screen themes, including a watch style face, but the device itself is more understated. It does not try to look expensive. It tries to disappear into your pocket and your day.
Score: design
OXVA Xlim Pro 2: 9 out of 10. Vaporesso XROS 5: 7 out of 10.
Battery: the round the XROS 5 clearly wins
This is the most important difference between the two kits, because it affects you every day. The XROS 5 carries a 1500mAh battery, 200mAh more than the Xlim Pro 2 at 1300mAh. In real use, that gap translates to a comfortable full day of moderate vaping for both kits, with the XROS 5 more likely to stretch into a second day for a lighter vaper, and the OXVA more likely to need an evening top up for a heavier vaper.
Charging widens the gap further. The XROS 5 supports 3A charging, reaching about 80 percent in roughly 20 minutes. The Xlim Pro 2 supports 2A charging, reaching about 80 percent in roughly 25 minutes. Five minutes does not sound like much on paper, but in practice the XROS 5 is the kit you can plug in while you make a coffee and come back to a nearly full battery. Both figures depend on the charger and cable you use, so a slow old phone charger will hold either kit back.
Score: battery
OXVA Xlim Pro 2: 7 out of 10. Vaporesso XROS 5: 9 out of 10.
Pods and coils: two strong ecosystems, one wider net
Both kits use fixed coil pods, which means when the coil wears out you replace the whole pod, not just a coil head. Refilling is top fill on both, so you pop off the mouthpiece cap, fill, and close it again, with no need to remove the pod from the device. Both pod ranges are widely stocked in the UK, so you are unlikely to struggle to find replacements for either.
The OXVA uses Xlim V3 pods, with 0.6 ohm and 0.8 ohm pods included in the box, and 0.4 ohm and 1.2 ohm options available for a looser or tighter draw. The mesh coils give a punchy, warm flavour, especially on the 0.6 ohm pod at higher wattage. The trade off, reported consistently across long term use, is that sweeter liquids can wear the higher resistance pods out a little faster, so a heavy dessert liquid vaper may change pods slightly more often.
The Vaporesso uses the XROS series pod range, with 0.6 ohm and 0.8 ohm COREX 3.0 mesh pods in the box, and 0.4 ohm, 1.0 ohm and 1.2 ohm options across the wider range. That wider range is a real advantage: because the XROS pod system has been around through several device generations, there are more resistances to choose from, and the pods have a reputation for lasting well even with sweet liquids. Leak resistance is also a strong point on both, thanks to sealed internal designs, but the XROS pods edge ahead on consistency over a long pod life.
Score: pods and coils
OXVA Xlim Pro 2: 8 out of 10. Vaporesso XROS 5: 9 out of 10.
Airflow and draw: tight and punchy versus smooth and steady
Both kits use a side slider to adjust airflow, and both cover the same ground: a tight cigarette style mouth to lung draw at one end, and a looser restricted direct to lung draw at the other. Neither is a true direct to lung cloud device, and neither pretends to be.
The difference is feel. The OXVA slider gives a punchier, more defined draw, with a slightly stronger throat hit at the same nicotine strength. That suits ex smokers who want the draw to feel like a cigarette, and it pairs well with the adjustable wattage, since you can tighten the airflow and drop the power for a cooler, sharper vape, or open it up and push the power for a warmer one.
The XROS 5 draw is smoother and more even across the slider range. It is less likely to feel harsh if you open the airflow right up, and the preset power modes keep the draw consistent from pod to pod. Beginners tend to prefer this, because there is less to get wrong. You set the slider where it feels right and the device handles the rest.
Score: airflow and draw
OXVA Xlim Pro 2: 8 out of 10. Vaporesso XROS 5: 8 out of 10.
Flavour: punchy versus consistent
Flavour is where personal taste matters most, and where the two kits split most clearly. The Xlim Pro 2 delivers a punchier, more intense flavour, especially on fruit liquids with the 0.6 ohm pod and the wattage pushed up. The top notes come through brightly, and the vape feels lively. That intensity is the reason many experienced pod vapers love the Xlim range.
The XROS 5 delivers a smoother, more consistent flavour across a wider range of liquids. Fruit, menthol, tobacco and dessert liquids all come through cleanly, and the flavour holds up better as a pod ages. Where the OXVA can fade or turn slightly muted on a sweet liquid after several days, the XROS 5 tends to stay steady for longer. Its 0.6 ohm pod is also the standout in its range, giving a full mouth to lung flavour without needing any wattage tweaking.
If you are still weighing a refillable kit against disposables, the best disposable vapes guide lays out when each format makes sense.
Score: flavour
OXVA Xlim Pro 2: 8 out of 10. Vaporesso XROS 5: 9 out of 10.
Charging and everyday living
Both kits charge by USB-C and show battery percentage on screen, but the XROS 5 is the easier kit to live with. It reaches about 80 percent in roughly 20 minutes, against about 25 minutes for the OXVA, and its larger screen is easier to read at a glance. Neither kit includes a plug in the box, only a cable, so use a modern USB charger to get those speeds.
Score: everyday living
OXVA Xlim Pro 2: 8 out of 10. Vaporesso XROS 5: 9 out of 10.
Running costs: nearly identical, with one quiet difference
Day to day running costs for these two kits are almost the same, and that is good news, because it means you can choose on performance rather than price. Both need the same things: replacement pods every week or two depending on use, and bottles of nic salt or 50VG and 50PG liquid. Neither kit locks you into expensive proprietary liquid, and both work best with standard nic salt strengths.
The quiet difference is pod life. Because XROS pods tend to last a little longer, especially with sweet liquids, a heavy dessert liquid vaper may get through slightly fewer pods per month on the XROS 5. The OXVA adjustable wattage can shorten pod life if you habitually vape at the top of the range.
Score: running costs
OXVA Xlim Pro 2: 8 out of 10. Vaporesso XROS 5: 9 out of 10.

It lasts longer between charges, charges faster, keeps flavour consistent for longer, and asks less of you day to day. For most vapers, most of the time, that is the kit that will cause the fewest frustrations.
Frequently asked questions
Which is better for a beginner switching from disposables?
The Vaporesso XROS 5. Its preset power modes mean there is no wattage to set wrong, and the draw is smooth and consistent.
Which pod kit has better battery life?
The Vaporesso XROS 5, thanks to its larger 1500mAh battery compared with 1300mAh on the OXVA Xlim Pro 2. It also charges faster, reaching about 80 percent in roughly 20 minutes with a suitable charger.
Can I use any Xlim pod in the Xlim Pro 2, and any XROS pod in the XROS 5?
Yes, within each family. The Xlim Pro 2 works with Xlim series pods, and the XROS 5 works with the full XROS series pod range. Pods are not interchangeable between brands, so OXVA pods will not fit a Vaporesso device and vice versa.
Which kit is better for sweet dessert liquids?
The Vaporesso XROS 5, because its COREX 3.0 mesh pods tend to hold flavour longer and resist the faster wear that sweet liquids can cause. The OXVA still handles dessert liquids well, but you may change pods slightly sooner.
Do both kits work with nic salts?
Yes. Both kits are designed for nic salt liquids and for 50VG and 50PG freebase liquids, and both ship with pods suited to mouth to lung vaping with nic salts.
Are these kits legal in the UK?
Yes. Both are refillable, rechargeable kits with 2ml pods in their UK versions, so they are not affected by the UK disposable ban.
Which kit should I buy if I want adjustable wattage?
The OXVA Xlim Pro 2. It offers fully adjustable output from 5W to 30W, while the XROS 5 uses ECO, Normal and Power presets for most pods, with finer adjustment only on the 0.4 ohm pod.
