The Uwell Caliburn G5 and Caliburn G5 KOKO share 90% of their internals — same coils, same 850 mAh battery, same PRO-FOCS chip. The 10% difference is what people argue about online. Here’s the real-world breakdown.
Quick verdict
- Buy the Caliburn G5 if you want a pen-style device that disappears in your pocket.
- Buy the Caliburn G5 KOKO if you want a square device that stands on its own and feels chunkier in the hand.
Specs side by side
- Battery — both 850 mAh, USB-C 1A.
- Output — both 25 W max, draw-activated.
- Pod — both 2 ml, top-fill, magnet-secured.
- Coils — both share the 0.8 Ω / 1.0 Ω G-series mesh coil family.
- Form — G5: cylindrical, 32 g. KOKO: squared “soap-bar”, 38 g.
- Airflow — both 6-stop adjustable ring.
Hand feel
The KOKO is the more confident grip — flat sides stop it rolling on a desk. The G5 is more discreet for jeans pockets and is the better travel companion.
Battery life in the real world
Both pull from the same 850 mAh cell, so expect ~450 puffs per charge at 25 W with a 0.8 Ω coil. The KOKO’s slightly larger surface dissipates heat better during chain vaping, but the difference is marginal.
Pod compatibility: G5 and G5 KOKO use the same pod. If you own one and want to buy the other later, your spare pods carry over.
Price
The Caliburn G5 retails around $29.99 and the G5 KOKO around $32.99. The KOKO is consistently $3–4 more for the alternate chassis — no internal differences justify the gap, so the choice is pure aesthetics.
Final pick
If we had to choose one, the Caliburn G5 wins on price, weight and pocketability. But the KOKO is undeniably the more striking object on a desk. Both are excellent.
