Battery
The Uwell Caliburn G5 KOKO wins on battery thanks to its 1600 mAh cell, well ahead of the 1000 mAh in the Vaporesso ECO NANO Pro. That gap in raw capacity is the deciding factor, even though the Vaporesso ECO NANO Pro offers a stated 20-minute charge to 80% and a 1 A charge current that the Uwell Caliburn G5 KOKO’s listing doesn’t specify. Faster top-ups don’t offset the smaller pack size, so the larger battery takes the category.
Performance
The Uwell Caliburn G5 KOKO takes performance on the strength of its 35 W max output versus 20 W for the Vaporesso ECO NANO Pro, giving it a wider power ceiling. It also lists four coil resistance options (0.4Ω, 0.6Ω, 0.9Ω, 1.2Ω) with wattage ranges tied to each, compared to the Vaporesso ECO NANO Pro’s four mesh coils without matching wattage figures. Since coil resistances aren’t directly comparable between the two, the higher stated wattage is what settles this one.
Convenience
The Vaporesso ECO NANO Pro wins convenience by offering adjustable airflow, a feature the Uwell Caliburn G5 KOKO lacks entirely, letting users fine-tune draw resistance to taste. Both devices are close in weight (65 g vs 66 g) and both have a display screen, so those factors don’t separate them, leaving airflow control as the meaningful edge for the Vaporesso ECO NANO Pro.
The Uwell Caliburn G5 KOKO suits vapers who want longer battery life and higher wattage headroom with more coil resistance choices.
The Vaporesso ECO NANO Pro suits vapers who want to adjust airflow to control draw and vapor feel.
The verdict
Neither device comes out ahead across the board. The Uwell Caliburn G5 KOKO leads on battery capacity and performance, backed by a larger 1600 mAh cell and a 35 W ceiling with more coil options, while the Vaporesso ECO NANO Pro takes convenience with its adjustable airflow. Some specs, like charge time, charge current, and build material, aren’t directly comparable between the two, so this is a case of picking the category that matters most to you rather than crowning one overall winner.
