Uwell Caliburn G3: simpler to pick up and use, with a more minimalist feel.
Who Are These Kits Really For?
The biggest difference between these two devices is not just the spec sheet. It is the type of user each one suits best in daily use.
- OXVA XLIM Pro 2: ideal for users who want a pod kit with a more premium feel, stronger battery life, adjustable power and airflow, and longer-lasting pods.
- Caliburn G3: better for users who want something simpler, cleaner and more plug-and-play with less setup and less adjustment.
If you are coming from disposables and want the easiest possible refillable route, the G3 has strong appeal. If you want a pod kit that gives you more room to fine-tune the vape and get better long-term value, the XLIM Pro 2 makes the stronger case.

Visual Comparison
The XLIM Pro 2 looks and feels more like a feature-led pod kit, while the Caliburn G3 leans into a cleaner, simpler design language. Neither approach is wrong. It depends on whether you want more control or less fuss.
OXVA XLIM Pro 2
Slim profile, brighter OLED screen, and a more feature-rich feel. It suits users who want better visibility, manual airflow control and stronger everyday flexibility.
Uwell Caliburn G3
Minimalist, compact and very pocket-friendly. It is a cleaner-looking device that appeals to users who want something simple and discreet.
Real-World Performance Compared
Flavour and Vapour
Both devices use built-in mesh pod systems and both can deliver strong flavour with nicotine salts. The XLIM Pro 2 usually feels richer and more adaptable because the airflow is easier to fine-tune, especially if you use the 0.6Ω pod and want a slightly warmer, fuller vape.
The Caliburn G3 still performs well, but it feels more straightforward than flexible. It is very good at what it does, but the XLIM Pro 2 gives you more room to dial in the vape to your preference.
Ease of Use
The Caliburn G3 is arguably the simpler device. There is less to think about, which is exactly why many beginners like it. If you want something that feels more “fill it, click it in and go”, the G3 has the edge here.
The XLIM Pro 2 is still easy to use, but the extra airflow and power flexibility mean there is a slightly bigger learning curve if you are completely new to refillable kits.
Pod Longevity
This is one of the areas where the XLIM Pro 2 usually pulls ahead. XLIM pods, especially the 0.8Ω mesh, are known for strong lifespan and more consistent flavour over time. In regular use, many users get 10–14 days before noticeable flavour drop-off.
The Caliburn G3 pods still perform well, but they are more likely to sit in the 5–8 day range for many users depending on liquid sweetness and usage.
Battery Life
The 1300mAh battery on the XLIM Pro 2 gives it a clear practical advantage. It is more likely to feel like a real all-day device, especially at lower wattages. The Caliburn G3’s 900mAh battery is enough for many users, but heavier vaping makes the difference noticeable.
Value Over Time
Both devices are close enough in price that long-term use matters more than the initial spend. Because the XLIM Pro 2 usually offers longer pod life, top-fill convenience and a bigger battery, it often ends up being the better long-term value choice.
Which One Should You Choose?
If you want the easiest possible route into refillable pod kits, the Caliburn G3 still makes a lot of sense. But if you want stronger long-term performance, more battery life and a more complete everyday package, the XLIM Pro 2 is the stronger overall buy.
