Battery
The Uwell Caliburn G5 Pod wins on battery, and the numbers make it clear why: its 1600 mAh cell is well ahead of the 1100 mAh battery in the Eleaf iVeni. Both devices are internal batteries, use a 2 A charge current, and reach 80% in about 30 minutes, so charging speed itself is a wash. The gap comes down to raw capacity, which should translate into more vaping time between charges for the Caliburn G5 Pod.
Performance
The Eleaf iVeni takes the performance category on the strength of its 40 W max output versus 35 W for the Caliburn G5 Pod, giving it a slightly higher power ceiling. The iVeni also lists four coil resistance options (0.4Ω, 0.6Ω, 0.8Ω, 1.2Ω) compared to two on the Caliburn G5 Pod (0.6Ω, 0.9Ω), though the coil comparison itself is marked as not directly comparable. Variable wattage is confirmed for the Caliburn G5 Pod but not stated for the iVeni, so that detail wasn’t factored into the win.
Convenience
Convenience ends in a tie. Both devices offer a display screen and adjustable airflow, and both charge via USB-C (listed as “Type C” for the Caliburn G5 Pod) with identical charge times and current. The Caliburn G5 Pod is notably lighter at 65 g versus 88 g for the iVeni, and it’s described with a premium aluminum alloy matte finish while the iVeni’s build material isn’t stated — but neither of those points was enough to break the tie in the computed result.
The Eleaf iVeni suits vapers who want a higher maximum wattage and more coil resistance options to choose from.
The Uwell Caliburn G5 Pod suits vapers who prioritize longer battery life and a lighter device to carry.
The verdict
Neither device comes out ahead across the board. The Uwell Caliburn G5 Pod has the clear edge in battery capacity and is lighter, while the Eleaf iVeni offers a higher max wattage and more coil resistance options. Convenience features land in a tie, since both share the same screen, airflow adjustability, and charging behavior. The right pick depends on whether longer battery life or a higher power ceiling matters more to you.
