The Uwell Caliburn G3 Pro KOKO is a compact refillable pod vape kit with a 1250mAh battery, 1.8 inch TFT colour display, and adjustable output from 5W to 35W. It's the square-shaped version of the G3 Pro, smaller in the hand but running the same 35W output and Caliburn G3 pod platform. You get button fire and auto-draw together, plus a stepless airflow slider for MTL and RDL.
Two Caliburn G3 pods come in the box, a 0.9 ohm side-fill for MTL and a 0.4 ohm side-fill for RDL, both with mesh coils already fitted. The Uwell KOKO vape works with nic salts, 50/50 freebase, and higher VG liquids. PRO-FOCS 3.0 flavour technology runs across the pod range, and Type-C fast charging gets you to 80% in 20 minutes.

The 1.8 inch TFT screen shows your wattage, battery percentage, coil resistance, and puff count all at once. There are dynamic theme animations built in, plus day and night modes that change the screen brightness and colour scheme depending on the time.
To change wattage on the G3 Pro KOKO, press the fire button three times to enter power adjustment mode. Each press after that cycles through the wattage levels from 5W up to 35W. Wait three seconds and it saves your setting. That's really all you need to know about how to use the G3 Pro KOKO day to day - set your wattage, pick your pod, and go.

The G3 Pro KOKO works with Caliburn G3 pods only. It doesn't take GPP pods like the G4 series does. Your kit ships with two side-fill pods out of the box.

Both KOKO pods use side-fill rather than top-fill, with mesh coils pre-installed. PRO-FOCS 3.0 (Precise Optimisation of Flavour with Complete Smoothness) is built into the coil platform and adjusts output to match whichever pod resistance you've got fitted. Caliburn KOKO pods hold 2ml (TPD) each.
If you're running nic salt e-liquids, the 0.9 ohm pod at lower wattages is the one to go for.

The G3 Pro KOKO uses a compact square shape rather than the cylindrical design on the standard G3 Pro. If you've seen it listed as the Caliburn G3 square or Caliburn COCO, it's the same kit. The matchbox-style form factor sits flat in a pocket or small bag, and the fire button and airflow slider are built into the square body so nothing sticks out.
This KOKO Caliburn is a caliburn vape with a screen too, not just a basic pod kit. You get the full 1.8 inch TFT display with wattage, battery, and puff count right on the front face. If you've been looking for a caliburn box vape or something more compact than the standard pod kits on the market, the KOKO shape is built around that idea.
The 1250mAh battery capacity lasts a full day on MTL at moderate wattages. Type-C charging runs at 5V/2A, getting the battery to 80% in about 20 minutes. The charge time from flat to full is roughly 40 minutes depending on your power source. The TFT screen shows your battery percentage at all times, and the charging cable comes in the box.

The KOKO comes in eight colour options:

The KOKO is for anyone who wants the full G3 Pro spec sheet in a smaller, squarer kit. You still get 35W output, the 1.8 inch TFT display, and the same Caliburn G3 pod platform. The difference is the shape and the slightly smaller 1250mAh battery (versus 1000mAh on the standard G3 Pro, so you're actually getting more battery here).
The 20 minute fast charge to 80% is handy if you're out and about. Our best Uwell G3 Series pod kits guide compares the KOKO against the standard G3 Pro and the rest of the range if you're trying to pick between them.
Depending on how many cigarettes you smoke, we recommend the following strength e-liquids with the Uwell Caliburn G3 Pro KOKO Pod Vape Kit.
