The Uwell Caliburn G5 Pod and Vaporesso XROS 4 Mini are both compact pod systems, but they take slightly different approaches to battery size, power and everyday handling. This comparison works through the published specs to see where each device has a genuine edge.
Rather than naming a single overall winner, we’ve broken the comparison into three categories — battery, performance and convenience — so you can weigh up which matters more for how you vape.

Battery
The Uwell Caliburn G5 Pod wins on battery thanks to its 1600 mAh cell against the Vaporesso XROS 4 Mini’s 1000 mAh, a meaningful difference in capacity that should translate into longer use between charges. It also charges faster, reaching 80% in 30 minutes compared with 45 minutes for the XROS 4 Mini, helped by its 2 A charge current versus 1 A. Both use an internal battery and a USB-C style port, so there’s no difference in charging method, only in speed and capacity.
Performance
The Uwell Caliburn G5 Pod takes performance too, with a higher max output of 35 W versus 30 W on the Vaporesso XROS 4 Mini, plus variable wattage control and a display screen that the XROS 4 Mini lacks. This gives the Caliburn G5 Pod more scope to fine-tune the vape rather than relying on fixed output. Both devices offer adjustable airflow, so that aspect is a tie, and coil resistance options are broadly similar (0.6Ω/0.9Ω versus 0.6Ω/0.8Ω) though not directly comparable enough to call a winner there.
Convenience
Convenience goes to the Uwell Caliburn G5 Pod, largely on the strength of its display screen, variable wattage and quicker charging, all of which make it easier to monitor and manage day to day. That said, the Vaporesso XROS 4 Mini is notably lighter at 46.5 g against 65 g, which some users will find more convenient for pocket carry and all-day handling, even though it doesn’t take the category win outright.
The Uwell Caliburn G5 Pod suits vapers who want a longer-lasting battery, faster charging, and more control over output via variable wattage and a display screen.
The Vaporesso XROS 4 Mini suits vapers who prioritise a lighter, more compact device over extra power or on-screen readouts.
The verdict
On the specs provided, the Uwell Caliburn G5 Pod leads across battery, performance and convenience, largely on the back of its larger battery, higher output, faster charging and added display and wattage control. The Vaporesso XROS 4 Mini’s clearest advantage is its lighter weight, which won’t show up in category scoring but may matter more than any spec sheet to some users. Neither device is declared an outright overall winner here — the choice comes down to whether stronger power and battery figures or a lighter, simpler unit suits you better.
