The Geekvape Wenax Q2 and Uwell Caliburn G5 KOKO are both pod kits aimed at everyday use, with displays, adjustable airflow and variable wattage. On paper they look similar in features, but the underlying figures show some clear gaps in battery size and output.
This comparison sticks strictly to the specifications and notes provided for each device, so where the data doesn’t stretch far enough to call a winner, we say so rather than guess.

Battery
The Uwell Caliburn G5 KOKO wins on battery, with a 1600 mAh cell against the Geekvape Wenax Q2’s 1250 mAh — a meaningful difference of 350 mAh that should translate into more time between charges. Battery type is only stated for the Wenax Q2 (built-in), and charge time to 80% (30 min) and weight (66 g) are each only given for one product, so those points can’t be compared directly; the capacity figures alone are enough to settle this category.
Performance
The Uwell Caliburn G5 KOKO also takes performance, with a max output of 35 W versus 30 W on the Geekvape Wenax Q2, giving it a bit more headroom for higher-wattage coils. The coil resistance ranges differ in format — the Wenax Q2 lists three resistances (0.4, 0.6, 0.8 ohm) without wattage bands, while the Caliburn G5 KOKO lists four resistances (0.4Ω to 1.2Ω) each with a specific wattage range — so the coil options aren’t directly comparable, but the stated max output figure is a clear, comparable number in the Caliburn G5 KOKO’s favour.
Convenience
Convenience is a tie. Both devices have a display screen, adjustable airflow and variable wattage, and both charge at 2 A. Beyond that, the data diverges into non-comparable specifics — charging port is described differently (Type-C for the Wenax Q2, 5V/2A for the Caliburn G5 KOKO), and build material is described differently too (matte leather and aluminium alloy vs leather-style) — so there isn’t enough shared, comparable evidence to separate them here.
The Geekvape Wenax Q2 suits buyers who want a built-in battery with a stated fast charge time of 30 minutes to 80%, in a simpler three-resistance coil lineup.
The Uwell Caliburn G5 KOKO suits buyers who want a larger 1600 mAh battery and higher 35 W max output, plus a wider range of coil resistance and wattage options.
The verdict
There’s no single overall winner here — the Uwell Caliburn G5 KOKO has the edge in the areas with clear, comparable figures, namely battery capacity and max output, while convenience features come out even based on what’s stated for both devices. Several specs, including charge time, weight, charging port detail and build material, are only given for one product or described in incompatible ways, so they’re left out of the scoring rather than guessed at. Choosing between them should come down to which of the confirmed advantages, or the tied convenience features, matter most to the buyer.
