Top of the Pods: OXVA vs. Caliburn

If you’re shopping for your next pod kit, you’ve probably come across OXVA and Uwell. Both brands are making serious moves in the UK vaping scene, with sleek designs, great flavour, and compact convenience. But when it comes to choosing between them, which one takes the top spot?

If you’re wondering which device is best for your needs, this guide will break down the key differences to help you make the right choice.

Let’s compare the two without the tech jargon — just real talk to help you decide what fits your style.

A Quick Introduction to Pod Systems

Pod systems have transformed the vaping journey, making it easier than ever for vapers to enjoy their favourite e-liquids with minimal fuss. These compact devices combine a rechargeable battery with a replaceable or refillable pod, which houses the coil and liquid.

Whether you’re just starting out or you’re an experienced vaper looking for a convenient backup, pod systems like the OXVA Xlim and OXVA Xlim Pro 2 offer a streamlined vaping experience that’s both satisfying and simple to use. The Uwell Caliburn series is another standout, known for its reliability and ease of use. With a wide variety of devices available, there’s a pod system to suit every style and preference, making vaping more accessible and enjoyable for vapers everywhere.

Build Quality and Design: First Impressions Matter

When it comes to pod systems, first impressions really do count. The OXVA Xlim Pro 2 stands out with its sleek, modern look and sturdy zinc alloy body, giving it a premium feel that’s built to last. It’s compact enough to slip into any pocket, yet feels substantial in the hand — perfect for vapers who appreciate both style and substance.

On the other side, the Uwell Caliburn G3 keeps things minimalist with a lightweight aluminium alloy frame, making it ultra-portable without sacrificing durability. Both devices are thoughtfully designed for everyday use, but the choice comes down to whether you prefer the solid, classy feel of the Xlim Pro or the featherlight convenience of the Caliburn. Either way, great build quality means you can count on a reliable vaping experience every time you pick up your pod.

Battery Life and Performance: Powering Your Vape

Battery life can make or break your vaping experience, especially if you’re always on the go. The OXVA Xlim Pro 2 is equipped with a 1000mAh battery, offering solid performance for a full day of vaping, while the Uwell Caliburn G3 steps it up with a 1300mAh battery for even longer sessions between charges.

Both pod systems are designed to keep you vaping without constant worry about finding a charger. Features like adjustable wattage, airflow control, and a handy puff count let you tailor your vape to your exact preferences, whether you want a tight MTL draw or a more open, airy hit. With these advanced features, you can fine-tune your power level and airflow for the perfect balance of flavour and vapour production, ensuring every puff is just right for you.

OXVA – The Customisation Queen

OXVA has really stepped up in 2025. Known for slick devices like the Xlim Pro 2 and Nexlim, this brand is winning over UK vapers who love a pod kit that packs in features and appeals to beginners and experienced vapers alike.

What stands out? For starters, flavour is bold and consistent, and the pods last longer than you’d expect — many users report multiple refills without a noticeable drop in taste. The anti-leak V3 pods also help keep things clean and reliable, which is a nice touch. OXVA pods are compatible with previous series, and the compatibility with a range of pods and accessories makes these devices versatile and easy to use.

Battery life is a big win, too. OXVA kits tend to last longer between charges thanks to their impressive battery capacity, and USB-C fast charging means you’re back to vaping quickly. If you’re someone who wants adjustable wattage, airflow options, and a bit of extra control, OXVA delivers all that in a lightweight, portable frame. The integration of these advanced features showcases the excellent functionality of OXVA devices.

Coil performance is also top-notch, with the cotton remaining fully saturated for optimal flavour and vapour production. The pod filling mechanism features a clever valve that helps prevent leaks and airlocks.

OXVA continues to release new pod kits in quick succession, ensuring frequent updates and improvements for users.

Caliburn – The Flavour Favourite

Uwell’s Caliburn is a name most vapers know, and for good reason. Since the original launched, it’s been the go-to for easy, flavour-packed vaping. The new Caliburn G4 is a new pod kit that continues the tradition with a few upgrades, including a colour screen, adjustable airflow, and modes like “storm” and “wave” for different power levels. This is great news for users who want the latest features and improved style.

The real hero here is the PRO-FOCS coil tech, which gives you clean, rich flavour whether you prefer MTL or RDL draws. It’s reliable, simple, and hits the sweet spot for those just getting into vaping, or anyone who doesn’t want to fuss with settings. The Caliburn operates at low wattage, making it ideal for beginners or those who prefer a milder vape and smoother throat hit.

It also supports auto-draw or button fire, so you choose how to vape. For manual activation, simply press the fire button to power the device or reset certain functions. The device’s output is stable, providing consistent vapour and flavour with every puff. The colour screen displays a puff counter, letting you track how many puffs you’ve taken and monitor your usage for device longevity.

The 1300 mAh battery sounds huge (and is), but real-world performance varies a bit. The Type-C charging port allows for convenient charging, and the device can recharge quickly so you’re not left waiting. Charging’s slower than OXVA, but it still holds its own for everyday use. For best maintenance, let the device stand upright after filling or charging. The overall performance of the Caliburn is impressive, with great flavour, solid battery life, and user-friendly operation.

Pod System Safety and Precautions

Safety is key to a great vaping experience, and a few simple habits can make all the difference. Always handle your pod system with care to avoid accidental drops or damage. Regularly check and clean your pod and coil to prevent dry hits and keep your flavour delivery on point. Pay attention to pod resistance and coil resistance, using the right combination to avoid overheating and keep your device running smoothly.

And of course, always keep your vape out of reach of children and pets, and follow the manufacturer’s guidelines for use and maintenance. By staying mindful of these basics, you’ll enjoy a safer, more satisfying vape every time.

So, Which One’s Better?

Final Verdict: It honestly depends on how you like to vape.

The moment you take your first puff from either device, you'll notice the immediate satisfaction and impressive flavour delivery that sets these kits apart.
