The OXVA XLIM series has consistently defined the high-performance pod category, and the SQ line has served as the square-format option, designed for users prioritizing capacity and pocketable ergonomics. The introduction of the XLIM SQ PRO 2 marks the most ambitious generational leap in the series, shifting the device from a robust standard pod system to a feature-rich, high-end portable device.
This upgrade thesis centers on two dominant advancements: a substantial increase in power endurance and the integration of a highly sophisticated interactive display. While the original XLIM SQ PRO, with its 1200mAh battery and 0.96-inch color TFT screen, remains an excellent entry point, the XLIM SQ PRO 2 is engineered to capture the heavy user and the technology enthusiast. The new model sets itself apart as the endurance king of the XLIM family, justifying its premium position by introducing advanced user interface technology previously reserved for complex box mods.
Design
The physical evolution from the OXVA SQ PRO to the XLIM SQ PRO 2 is necessitated by the device’s internal hardware upgrades. The original SQ PRO features a more traditional, squat square form factor, appealing to users seeking maximum portability and a true palm-sized feel.
The XLIM SQ PRO 2 transitions to a taller, rectangular design with softly rounded corners, measuring 93.4 mm in height, 48 mm in width, and 20.01 mm in depth.6 This increase in physical size is a functional decision, structurally required to accommodate the larger 1600mAh battery cell and the dominant 1.09-inch HD touch screen.7 This results in a noticeably heavier device, weighing in at 114 grams. Constructed from zinc alloy and featuring IML or artificial leather panels, the SQ PRO 2 achieves a premium feel. However, this trade-off repositions the device. It moves away from the ultra-compact, discreet vaping category and closer to a powerful, feature-dense “mini-mod.” The added height is reported to make the device more comfortable for screen interaction, but it undeniably reduces the device’s overall ‘stealth factor’ compared to its predecessor.7
Battery
The most compelling quantitative difference between the two models lies in power delivery and capacity. The XLIM SQ PRO is well-regarded for its robust 1200mAh integrated battery, which generally ensures comfortable all-day use for an average vaper.
The XLIM SQ PRO 2, however, elevates endurance significantly by integrating a 1600mAh rechargeable battery. This represents an approximate 33% increase in capacity, cementing its status as the XLIM line’s battery leader. This substantial endurance gap is particularly attractive to heavy, frequent vapers or those seeking a device that can reliably last beyond a single day, minimizing charging anxiety.
To mitigate the extended charging time inherent to a larger cell, the XLIM SQ PRO 2 supports 5V/2A Type-C fast charging. This feature ensures that the device can recover quickly, getting from empty to fully charged in an impressively short duration, which is crucial for users who are constantly on the move.1 The SQ PRO 2 is engineered to be the ultimate set-it-and-forget-it power device, supporting sustained 30W maximum output with improved efficiency, further enhanced by the presence of an ‘Eco Mode’ accessible via the menu, designed to maximize battery life when necessary.
Hardware
While the XLIM SQ PRO introduced a vibrant 0.96-inch color TFT screen, the XLIM SQ PRO 2 redefines the user interface with its 1.09-inch HD Smart Touch Screen.6 This technology is positioned as the first touch-screen pod system in the XLIM family, representing the device’s main competitive feature.
The XLIM SQ PRO 2 shifts the paradigm of interaction away from multi-click button sequences and toward intuitive gestures. Users can operate the device primarily via swipes and touches, unlocking the screen with a swipe on the lower third, and accessing comprehensive menu settings by swiping down. This highly intuitive interface offers a level of customization and data monitoring traditionally reserved for advanced regulated hardware. Advanced features include changeable themes, animations, and standby wallpapers. Furthermore, the system includes practical utilities like a flashlight, a stopwatch, a calendar, and a detailed 30-day puff diary, allowing users to track their usage patterns over time. This technological leap appeals directly to tech-savvy vapers who value personalized feedback and granular control over their experience.
Experience 
Despite the vast hardware differences, the core vaping performance of both the SQ PRO and the XLIM SQ PRO 2 achieves parity, which is a testament to the success of the shared ecosystem. Both devices leverage the highly acclaimed, universal XLIM pod system, including the Top Fill cartridges. This cross-compatibility is a significant consumer-friendly factor, meaning existing pod inventories remain usable across both generations
The XLIM pods are known for delivering intense, “X-Treme Flavor” and boast impressive coil longevity. Reports indicate that these pods can last exceptionally long, with some surpassing 40mL of e-liquid usage before flavor quality diminishes.5 Both devices support a full range of XLIM pods (0.4Ω, 0.6Ω, 0.8Ω, 1.2Ω) and accommodate both nicotine salts (recommended for 0.8Ω and 1.2Ω) and freebase e-liquids (recommended for 0.4Ω and 0.6Ω).
In terms of draw, both models offer adjustable side airflow control, accommodating both tight MTL (Mouth-to-Lung) and loose RDL (Restricted Direct-to-Lung) vaping styles. Some hands-on assessments suggest the XLIM SQ PRO 2 might offer a slightly tighter and punchier hit, which is often favored by heavy nicotine users.18 However, since the fundamental atomizer technology is identical, the decision between the two systems must be based on the device body’s features, battery life, and UI, rather than a core difference in flavor output.
For clarity, the key technical specifications defining the separation between the generations are summarized below:

Verdict
The choice between the XLIM SQ PRO and the XLIM SQ PRO 2 depends entirely on user priorities regarding budget, portability, and feature demand.
The XLIM SQ PRO remains an exceptional, reliable device. It is ideal for the budget-conscious vaper, the user who prefers the robust simplicity of a smaller form factor, or those who find a 1200mAh battery sufficient for their daily needs. It provides the same award-winning flavor profile as its successor without the added complexity or cost of the new features.
The XLIM SQ PRO 2 is a substantial upgrade, positioning itself as a high-end investment defined by technological innovation and unparalleled endurance. It is the definitive choice for the following demographics:
-
The Heavy User: Those who need the absolute maximum endurance offered by the 1600mAh battery and rely on 2A fast charging to minimize downtime.
-
The Tech Enthusiast: Vapers who demand advanced functionality, customization options (themes, animations), and detailed data monitoring provided by the 1.09-inch HD touch screen.
-
The Upgrader: Experienced vapers who appreciate refined details and want a device that showcases the latest advancements in compact vaping technology.
Ultimately, if flavor performance is the singular priority, the two devices are equal. However, if extended battery life, personalization, and a modern, interactive interface are paramount, the XLIM SQ PRO 2 justifies its premium standing, showcasing the trajectory toward smarter, more feature-rich pod systems.
