The Caliburn G3 and G3 Pro look like close relatives, yet the Pro is a noticeably more advanced device. The G3 Pro upgrades the G3 with a larger full colour screen, a bigger 1000mAh battery, 35W of power instead of 25W and a dedicated airflow slider, while the standard G3 stays lighter, simpler and cheaper. This guide explains the differences and whether the upgrade is worth paying for.

For the wider picture, our guide on the Caliburn range explained covers every model. Our comparison of the Caliburn G2 versus G3 looks at the previous generation.

Same pods, different ambitions

The two devices are closely related and, helpfully, both use the same G3 pod platform, so pods are interchangeable between them. Where they differ is ambition. The standard G3 aims to be a clean, simple, flavour focused pod kit that does the basics brilliantly. The G3 Pro reaches higher, adding power, a much bigger screen and finer control for vapers who want a more capable, mod like experience without the bulk. Neither is trying to be the other, so the choice is less about which is better overall and more about how much device you actually want in your pocket.

Where the G3 Pro pulls ahead

The Pro earns its name with several real upgrades. Power rises from 25W to 35W, giving more headroom for warmer, fuller draws and a proper restricted direct lung option. The battery grows from 900mAh to 1000mAh for longer between charges. The standout is the large full colour LCD that wraps around the device, showing wattage, battery, coil resistance and puff count clearly, with adjustable themes and brightness. Airflow moves to a dedicated side slider for smooth, precise tuning, while a new 0.4 ohm pod opens up RDL vaping. For control and feedback, the Pro is clearly the more capable device.

Where the standard G3 still wins

The base G3 holds genuine appeal and is far from outclassed. It is lighter and slimmer than the Pro, which makes it the more pocket friendly and discreet of the two, plus it is cheaper, which matters if you do not need the extra features. For someone who vapes a tight mouth to lung draw and never touches wattage or airflow settings, the Pro's headline features are largely wasted, since the simpler G3 gives the same excellent flavour from the same pods. If you want a no nonsense everyday pod kit rather than a feature showcase, the standard G3 remains a smart, sensible choice.

To see both side by side, the Uwell Caliburn collection lists the G3, the G3 Pro and their shared pods so you can compare specs and prices directly.

Is the upgrade worth it?

Whether the Pro justifies its higher price comes down to how you vape. If you enjoy fine tuning your wattage and airflow, want a clear screen full of data or fancy dabbling in restricted direct lung vaping with the 0.4 ohm pod, the upgrade is well worth it and the Pro is one of the most capable pod kits around. If you are a tight MTL vaper who just wants great flavour with minimal fuss, the extra features will sit unused, so the money is better kept for pods and liquid. There is no wrong choice, only whether you will actually use what the Pro adds.

Size and feel

One practical trade off is size. The G3 Pro is taller, wider and heavier than the standard G3, partly to house the bigger battery and that wraparound screen, with a more substantial zinc alloy feel in the hand. Some vapers love the premium heft and the display, while others prefer the lighter, more discreet standard G3 that disappears into a pocket. If portability and a low profile matter to you, the base G3 has the edge. If you do not mind a little extra bulk for the screen and power, the Pro feels appropriately premium. It is worth handling both if you can.

How they compare to the rest of the range

Stepping back, it is worth seeing how these two sit against their siblings. Below them, the original Caliburn and the A series offer the simplest, cheapest tight MTL vaping with no settings at all, while the older G2 brought replaceable coils and a full airflow dial. Above and alongside the G3 Pro, the Caliburn X offers a different take on the premium pod kit, pairing adjustable wattage with replaceable coils rather than fixed pods. So the G3 and G3 Pro represent the modern, screen equipped heart of the range, with the Pro reaching toward the enthusiast end. Our Caliburn X review is a useful comparison if you want adjustable power with swappable coils.

If you are still unsure which way to go, the honest advice is to start from how you actually vape rather than from the spec sheet. A bigger number on a screen is only worth paying for if you will use it, since plenty of happy Caliburn owners never change a single setting. Our buyer's guide on which Caliburn you should buy walks through the key questions of experience, draw style, usage and budget in order, which is the quickest route to the right model for you between these two and the wider lineup.

The bottom line

The Caliburn G3 Pro is a genuine step up from the G3, adding 35W of power, a 1000mAh battery, a large full colour screen, a dedicated airflow slider and an RDL pod option, all while sharing the same pods. The trade off is a larger, heavier and pricier device. If you will use the extra power and control, the Pro is one of the best pod kits available and the upgrade is worth it. If you just want simple, flavourful MTL vaping, the lighter, cheaper standard G3 is all you need. Match the device to how you actually vape.
