The Uwell Caliburn G5 Pod and Vaporesso XROS 4 Mini are both compact pod systems, but they take different approaches to battery size, control, and portability. This comparison looks strictly at the published specs to see where each device holds an advantage.
Rather than crowning one overall winner, we break the matchup into three categories — battery, performance, and convenience — so you can weigh what matters most for your own use.

Battery
The Uwell Caliburn G5 Pod wins on battery with a 1600 mAh cell versus the 1000 mAh in the Vaporesso XROS 4 Mini, meaning it holds substantially more charge between top-ups. It also charges faster, reaching 80% in 30 minutes compared to 45 minutes for the XROS 4 Mini, and does so with a higher 2 A charge current versus 1 A. Together these figures make the Caliburn G5 Pod the clear choice for anyone who wants fewer charging interruptions.
Performance
On performance, the Uwell Caliburn G5 Pod again comes out ahead with a 35 W max output against the XROS 4 Mini’s 30 W, giving it a slightly wider power ceiling. It also supports variable wattage, a feature the XROS 4 Mini lacks, allowing users to fine-tune output rather than rely on fixed settings. Both devices offer adjustable airflow, so that aspect is a tie, but the added output range and wattage control give the Caliburn G5 Pod the category win.
Convenience
The Uwell Caliburn G5 Pod takes the convenience category thanks to its built-in display screen, which the XROS 4 Mini does not have, giving users visual feedback on settings and battery level. Faster charging and higher charge current also reduce downtime, reinforcing the Caliburn G5 Pod’s edge here. The Vaporesso XROS 4 Mini does counter with a lighter build at 46.5 g versus 65 g, which matters for pocket comfort, but the specs that define this category still favor the Caliburn G5 Pod.
The Uwell Caliburn G5 Pod suits users who want longer battery life, faster charging, and more control over output via variable wattage and a display screen.
The Vaporesso XROS 4 Mini suits users who prioritize a lighter, more pocketable device over battery capacity or extra display features.
The verdict
Neither device sweeps every consideration: the Uwell Caliburn G5 Pod leads in battery capacity, power ceiling with variable wattage, and convenience features like its display and faster charging, while the Vaporesso XROS 4 Mini holds a clear weight advantage for those prioritizing a smaller, lighter carry. Coil resistance options, charging port type, and build material differences are noted but don’t favor either side conclusively based on the data given. The right pick depends on whether raw battery life and control matter more to you than a lighter, more pocketable form factor.
