OXVA XLIM SQ Pro 2 UK launch watch: touch screen, puff diary and 2ml checks

The OXVA XLIM SQ Pro 2 is worth watching if you are an adult UK vaper who already likes the XLIM pod ecosystem and wants a more feature-heavy refillable device. The short version: OXVA is presenting it as a premium square-format pod with a 1.09-inch touch screen, 1600mAh battery, 5-30W output, puff diary and XLIM pod compatibility, but UK buyers should still check three things before treating it as a straightforward purchase: the kit must be the 2ml/TPD version, the specific product should appear on the MHRA published-products listing, and replacement pods should be easy to buy at sensible GBP prices.

That matters because global product pages often show the full international story before every UK retail route is settled. OXVA's own page lists a 2ml/2ml(TPD) cartridge capacity and describes the XLIM SQ Pro 2 as the XLIM family's first touch-screen pod, with a 5-digit puff counter and usage diary tracking up to 30 days. Those are useful launch details, but they are still manufacturer claims until there is UK retail packaging, hands-on testing and a clear replacement-pod route to compare.

This guide is written for adults aged 18+ only. It does not treat a device listing as a safety endorsement, and it does not make health or cessation claims. It is a practical buyer check for a regulated UK category.

If the XLIM SQ Pro 2 appears in front of you as a UK purchase option, start with the compliance basics rather than the screen animation.

The 2ml point is not optional. GOV.UK retailer and producer advice says tanks exceeding 2ml are non-compliant and cannot be supplied in the UK, even as part of a notified product or kit: https://www.gov.uk/government/publications/advice-for-retailers-and-producers. For a launch-watch device, that means the adult buyer's question is not simply “does this model exist?” It is “is this the compliant UK version being offered through a responsible route?”

The same logic applied in our earlier OXVA UNIONE explainer, where 2ml wording was central to understanding a UK-facing kit rather than an international spec sheet.

OXVA's official XLIM SQ Pro 2 page positions the device as a premium, screen-led refillable pod. The headline feature is the HD smart touch screen, backed by a square body, side airflow control, wattage adjustment and a puff diary interface. OXVA lists the battery at 1600mAh and the output range at 5-30W.

The touch screen is the part that makes the SQ Pro 2 feel different from many existing XLIM devices. For experienced adult vapers, a screen can be genuinely useful when it makes wattage, battery status, lock settings and usage information easier to read. It can also be unnecessary if you prefer a simple pod you can set once and leave alone.

That is the key tension with this device. The XLIM SQ Pro 2 is not just trying to be another small refillable pod; it is trying to be a more device-like XLIM kit with a bigger battery claim and more visible controls. That may appeal if you like fine-tuning and want the square form factor. It may be more than you need if your ideal pod is light, simple and discreet.

The puff diary needs careful wording. OXVA describes a 5-digit counter and intelligent puff diary tracking up to 30 days. In plain English, that means the device can show usage information on the screen over time.

For an adult user who already vapes, that could be useful for practical reasons: noticing when a pod has had heavy use, seeing how your battery life changes with a higher wattage, or spotting whether a coil is being pushed harder than expected. It is best treated as a device-management feature, not advice and not a medical tool.

The Vapour Hut will not repeat cessation-adjacent marketing wording here. A puff counter does not make a vaping product a stop-smoking product, and this article does not claim the device provides a health benefit. It is simply an on-device tracking interface.

There is also a usability question. Touch screens on compact pods can be excellent when the software is clear and responsive, but they can be frustrating if the lock behaviour, swipe controls or menu layout feel fiddly. Until there is hands-on testing of the UK kit, the sensible position is to say the feature is promising on paper rather than proven in daily use.

OXVA's most eye-catching performance claim is the 1600mAh battery paired with “one charge = one week” style Eco Mode messaging and a 45-minute full-charge claim. The battery capacity is large for this class of refillable pod, especially next to OXVA's XLIM Pro 2, which VapeGreen's review lists at 1300mAh with a 5-30W output and a smaller screen: https://vapegreen.co.uk/blog/oxva-xlim-pro-2-review

That does not mean every adult user should expect a week from one charge. Battery life on a refillable pod changes with several ordinary variables:

The 1600mAh figure still matters. If accurate in the UK retail kit, it gives the SQ Pro 2 a meaningful capacity advantage over many slimmer pod systems. But the more honest buyer expectation is “potentially strong battery headroom for a refillable pod” rather than “guaranteed week-long use”.

Charging is similar. OXVA lists 5V/2A Type-C charging and a 45-minute full-charge claim. That is a useful spec if you already use a suitable charger, but real charging time can vary by cable, power source, remaining battery and device condition. Treat it as an official claim unless The Vapour Hut later tests a retail unit.

The strongest reason to watch the SQ Pro 2 is not only the screen. It is the XLIM pod ecosystem around it.

OXVA says the kit uses XLIM Top Fill cartridges, with a 0.6 ohm pod pre-installed and a 0.8 ohm pod in the box. OXVA's compatibility wording lists 0.4, 0.6, 0.8 and 1.2 ohm XLIM pod options, while its comparison section names XLIM Top Fill, XLIM V2 and XLIM EZ cartridges.

That gives existing XLIM users a possible upgrade route, but it also creates a buyer-check job. Before buying, check the exact pod names supported by the retail listing and the replacement pack you plan to buy. XLIM ranges are broad enough that a quick compatibility assumption can lead to the wrong pod.

VapeGreen's OXVA XLIM V3 replacement-pod page lists 3 x 2ml pods at £8.99, with 0.4, 0.6, 0.8 and 1.2 ohm options: https://vapegreen.co.uk/oxva-xlim-v3-replacement-pods-3-pack. That gives useful GBP context for ongoing pod costs in the XLIM ecosystem, but it should not be read as evidence that VapeGreen stocks the SQ Pro 2 kit itself unless the kit listing is live.

We covered the wider XLIM compatibility issue in our guide to OXVA XLIM prefilled pods, where the practical advice was to check pod families before treating any pod as a drop-in replacement. The same habit applies here.

The XLIM SQ Pro 2 and XLIM Pro 2 sit close enough that many adult buyers will compare them. The Pro 2 is already easier to understand because there is more hands-on retailer context around it. The SQ Pro 2 is the newer watch-list device with a larger battery claim, a bigger interface and a square body.

The SQ Pro 2 is likely to make most sense for adult users who actively want the screen and do not mind a heavier square device. If you mainly want a simple refillable pod, the screen and diary may be extra complexity rather than value.

That is not a criticism of the device. It is a way to buy it for the right reason. The SQ Pro 2 should stand or fall on whether its interface improves daily use, whether its battery claim holds up in realistic settings, and whether UK buyers can get the right 2ml pods without fuss.

Provisional launch-watch score: 4/5. This reflects the official specification and ecosystem fit, not a hands-on review. It should be revisited if The Vapour Hut tests a UK retail unit.

The OXVA XLIM SQ Pro 2 is an interesting launch-watch candidate for adult UK vapers, especially if you already like XLIM pods and want a more premium screen-led kit. The official specification is strong on paper: 1600mAh battery, 5-30W output, 1.09-inch touch screen, puff diary, side airflow and broad XLIM pod compatibility.

The careful buying advice is just as important. Confirm the UK 2ml/TPD kit, check the MHRA published-products listing without treating it as an approval, and make sure the replacement pods you want are actually available in the correct format. Read OXVA's battery and Eco Mode claims as manufacturer figures until there is hands-on testing.

If those checks line up, the SQ Pro 2 could be one of the more interesting refillable pod launches in the XLIM range. If they do not, wait for clearer UK retail evidence before buying.
