The Geekvape Wenax Q2 and Uwell Caliburn G5 KOKO are both compact pod systems aimed at everyday vapers who want a simple, portable setup. On paper they share some features, like a display screen and variable wattage, but differ in battery capacity, output, weight, and airflow control.
This comparison sticks strictly to the specs provided, calling out where one device has a clear edge and being upfront about the areas where the data just isn’t there to make a fair call.

Battery
The Uwell Caliburn G5 KOKO wins on battery with a 1600 mAh cell against the Geekvape Wenax Q2’s 1250 mAh, a meaningful gap that should translate into more vaping time between charges. The Wenax Q2 does list some charging specifics the G5 KOKO doesn’t, including a 30-minute charge to 80% and a 2A charge current over Type-C, but since the G5 KOKO’s battery type and charge time aren’t stated, those figures can’t be directly compared. The category win goes to the G5 KOKO on capacity alone.
Performance
Performance is a tie. The Uwell Caliburn G5 KOKO has a higher max output at 35 W versus the Geekvape Wenax Q2’s 30 W, which could matter for vapers who want more power on tap, but the Wenax Q2 counters with adjustable airflow, letting users fine-tune draw resistance in a way the G5 KOKO’s fixed airflow doesn’t allow. Coil resistance options differ in structure enough that they aren’t directly comparable: the Wenax Q2 lists four resistances without wattage ranges, while the G5 KOKO pairs each resistance with a specific wattage window. With each device holding an advantage in a different area, neither comes out ahead overall.
Convenience
The Geekvape Wenax Q2 takes convenience, largely on the strength of its adjustable airflow, which gives users more control over the vaping experience day to day. It is heavier than the Uwell Caliburn G5 KOKO at 78.6 g versus 66 g, so the G5 KOKO has an edge in portability and pocket feel, but that alone wasn’t enough to shift the category win given the airflow flexibility the Wenax Q2 offers.
The Geekvape Wenax Q2 suits vapers who want hands-on control over their draw through adjustable airflow and don't mind a slightly heavier device.
The Uwell Caliburn G5 KOKO suits vapers who prioritize longer battery life, higher max output, and a lighter, more portable device.
The verdict
Neither device sweeps the comparison. The Uwell Caliburn G5 KOKO leads on battery capacity and max output, making it the stronger pick for anyone prioritizing runtime and raw power, while the Geekvape Wenax Q2 counters with adjustable airflow and takes the convenience category despite being the heavier of the two. Performance ends in a tie, since each product’s advantages offset the other’s. Several specs, including charge time, charge current, battery type, and build materials, aren’t directly comparable due to missing data on one side or the other, so this is best read as a category-by-category decision rather than a single winner.
