A 20-minute Type-C charge to 80% and a stepless airflow slider covering both mouth-to-lung and restricted direct lung draws give the Uwell Caliburn G3 Pro Koko Pod Kit a usability edge over many compact vaping devices in its class. Sitting alongside the wider Uwell range and other compact pod kits on WizVape, the G3 Pro Koko combines a 1250mAh battery, 35W adjustable output, and PRO-FOCS 3.0 flavour technology in a square KOKO form factor. Two Caliburn G3 mesh pods are included in the box, a 0.9Ω for mouth-to-lung and a 0.4Ω for RDL. In stock in the UK and ready to dispatch.
Below we break down the key features, pod compatibility, and real-world performance of the Uwell Caliburn G3 Pro Koko to help you decide if it's the right vape for you.
The square KOKO profile is the most immediate point of difference. Where the standard Caliburn G3 Pro uses a cylindrical tube, the Koko sits flat in a pocket or bag without the roll-and-shift you get from round devices. The stepless airflow slider adjusts draw resistance continuously from a tight mouth-to-lung pull through to a looser restricted direct lung draw, and the fire button plus auto-draw activation mean you can use either method without rearranging your grip.
Beneath that form factor sits the same 35W output and Caliburn G3 pod platform as the standard G3 Pro, with PRO-FOCS 3.0 flavour technology built into the coil architecture. The G3 Pro Koko uses smart mode to detect coil resistance on pod insertion, suggesting an appropriate wattage starting point rather than defaulting to a flat setting. You can override that with the fire button controls, stepping from 5W to 35W in adjustable increments. The full Uwell vape kits range is available for comparison if you want to weigh the Koko against other devices in the line.
The 1250mAh battery tops up to 80% in under 20 minutes on a 5V/2A Type-C connection. The 1.8 inch TFT colour screen displays wattage, battery percentage, coil resistance, and puff count simultaneously, with day and night mode brightness switching built in.

The G3 Pro Koko uses a square profile that sits flat in a pocket rather than rolling. The fire button and stepless airflow slider are flush with the body, keeping the overall footprint tight while covering both mouth-to-lung and RDL draw styles within a single, pocket-sized pod system.

PRO-FOCS 3.0, Precise Optimisation of Flavour with Complete Smoothness, is built into the Caliburn G3 mesh coil platform. The mesh heats e-liquid across a wider surface than wire coils, typically producing more even wick saturation and consistent flavour from the first draw through to the end of the pod fill.

The 1.8 inch TFT colour screen shows wattage, battery level, coil resistance, and puff count at a glance. Smart mode detects the inserted pod resistance automatically and adjusts the suggested wattage accordingly, reducing the chance of firing a new coil at an unsuitable power level straight out of the box.
PRO-FOCS 3.0, which Uwell describe as Precise Optimisation of Flavour with Complete Smoothness, is built into the Caliburn G3 mesh coil platform rather than applied as a separate chipset feature. The mesh coil design distributes heat across a wider surface area than wire coils, which typically produces more even e-liquid saturation and a more consistent flavour profile from the first draw through to the end of the pod's usable life. Under moderate use, most vapers find flavour holds steadily across the full pod fill before tapering as the wick approaches depletion.
Pod lifespan on the Caliburn G3 platform depends largely on e-liquid choice. Sweetened e-liquids, particularly those high in sucralose, shorten pod life by leaving a caramelised residue on the mesh. Running a 50/50 nicotine salt at moderate wattages through the 0.9Ω pod typically gives longer consistent performance than pushing heavily sweetened blends through the mesh at elevated output. When you notice a drop in flavour quality or a burnt note, replacing the pod is the appropriate step rather than adjusting wattage upward.
The Caliburn G3 Pro Koko takes Caliburn G3 side-fill pods. Two pods ship with the kit: the 0.9Ω mesh pod for mouth-to-lung vaping at 10 to 15W, and the 0.4Ω mesh pod for restricted direct lung draws at 20 to 35W. Both arrive with mesh coils pre-installed and fill through a rubber side port, so no separate coil fitting is needed before first use. Replacement Uwell replacement coils and Uwell Caliburn pods for the G3 platform are stocked on WizVape.
Additional Caliburn G3 pod resistances are available to buy separately, including 0.6Ω and 0.8Ω options, giving more choice on draw resistance beyond the two included pods. The coil finder on WizVape helps narrow down compatible G3 options if you are switching from a different pod platform or want to match a specific draw style to the right resistance.
Both Caliburn G3 pods included in the G3 Pro Koko kit arrive with mesh coils pre-fitted and fill via a rubber side port. The coil finder can match any additional Caliburn G3 resistance to your preferred e-liquid and draw style. The full range of replacement options is available in the Uwell Caliburn pods collection on WizVape.
All pods hold 2ml of e-liquid in line with UK TPD requirements. Each pod is a complete unit with a mesh coil built in, so when flavour drops off or a burnt note appears, the whole pod is replaced rather than swapping a separate coil.
| 0.9Ω | 10–15W (MTL) | Tight mouth-to-lung draw, suits nic salts and 50/50 e-liquids up to 20mg. Included in kit. |
| 0.4Ω | 20–35W (RDL) | Looser restricted direct lung draw, suits 50/50 and higher VG freebase e-liquids. Included in kit. |
All Caliburn G3 pods for the G3 Pro Koko are 2ml capacity, in line with UK TPD regulations. The 0.9Ω pod is the recommended choice for nicotine salts at higher strengths. The 0.4Ω pod is best used with freebase e-liquids. Always match the PG/VG ratio of your e-liquid to the pod resistance fitted.
The Caliburn G3 Pro Koko delivers consistent draw character across both included pods when used within the recommended wattage ranges. The 0.9Ω pod at 10 to 15W produces a quiet, tight mouth-to-lung draw suited to all-day vaping with nic salts, while the 0.4Ω pod at 20 to 35W opens the draw up for a more airy RDL experience with noticeably more vapour output. Smart mode reads the inserted pod resistance on connection and adjusts the suggested wattage accordingly, which reduces the risk of firing a new pod at an unsuitable power level.
The side-fill design requires removing the rubber bung before adding e-liquid, which becomes straightforward after the first fill. Button and auto-draw activation both function reliably, and the stepless airflow slider responds predictably across its range. The puff counter on the TFT screen is a practical usage tracker for vapers monitoring their intake, and the lock function, activated by five presses of the fire button, prevents accidental firing in a pocket or bag. Avoiding sweetened e-liquids with high sucralose content is the most practical step for extending the time between pod replacements.

The Caliburn G3 Pro Koko adds 250mAh of battery over the standard Caliburn G3 Pro, running on a 1250mAh cell compared to the cylindrical model's 1000mAh, giving it a longer expected session time under typical MTL use despite the more compact square shape. Both devices share the same 35W maximum output, Caliburn G3 side-fill pod platform, and PRO-FOCS 3.0 flavour technology, so pods and replacement coils are interchangeable between the two.
The KOKO form factor is the defining reason to choose one over the other. If you carry your vaping device loose in a pocket or small bag and prefer something flat over a cylinder that rolls to the side, the square profile addresses that directly. Vapers already using the standard G3 Pro with a pod and coil stock will find the Koko compatible with everything they already own.
Under moderate mouth-to-lung use at 10 to 15W, most vapers find the Caliburn G3 Pro Koko lasts a full day on a single charge from the 1250mAh battery. Stepping up to restricted direct lung use with the 0.4Ω pod at 20 to 35W draws the battery down faster, and a reasonable expectation under heavier use is five to eight hours before needing to plug in. Type-C charging at 5V/2A restores the battery to 80% in under 20 minutes from a compatible charger, making a short top-up during a break a practical substitute for carrying a second device.
Before first use, fill the pod through the side port and leave it to stand for five minutes before firing. This allows the e-liquid to saturate the mesh coil fully and reduces the chance of a dry hit on the first draw. The 0.4Ω RDL pod benefits from a slightly longer stand of five to ten minutes given its larger mesh surface area.
The stepless airflow slider is worth experimenting with across its full range before settling on a fixed position. The 0.9Ω MTL pod works well with nicotine salts and 50/50 e-liquids at 10 to 15W, while the 0.4Ω pod handles 50/50 and higher VG freebase blends at 20 to 35W. Avoiding heavily sweetened e-liquids, those with a high sucralose content, will extend pod lifespan noticeably and maintain flavour quality across more fills.
The Caliburn G3 Pro Koko suits vapers who carry their device daily and want a pod kit that handles both mouth-to-lung and restricted direct lung vaping without switching between devices. The square form factor makes it easier to carry flat in a pocket than a cylindrical device, the fast charge speed reduces downtime between sessions, and the TFT display gives more feedback and control than basic pod kits offer. The two included mesh pods cover both draw styles without any additional purchase at the point of opening the box.
It is less suited to vapers whose primary interest is high-wattage sub-ohm performance or cloud volume. The 35W ceiling and 2ml TPD pod capacity place it in the compact and portable category, and vapers looking for more output will find more suitable options across the Uwell vape kits range.

For the Uwell Caliburn G3 Pro Koko Pod Kit, 50/50 VG/PG suits the tighter MTL draw and a 60/40 blend covers both styles comfortably. It supports both mouth-to-lung and restricted direct-to-lung vaping, with coil resistances spanning from 0.4Ω to 1.2Ω and an output range of 5-35W. For MTL use, nicotine salts are the stronger choice, higher strengths sit comfortably within the tighter draw. On the more open RDL setting at increased wattage, freebase e-liquids at 3mg or 6mg are more appropriate.
Each pod holds 2ml of e-liquid with a side fill design for easy, mess-free refilling. 70/30 and higher-VG blends are generally not a good fit for the MTL coil setting, the thicker consistency can restrict wicking at these wattages and may result in dry or burnt hits. For the MTL draw setting, Bar Juice 5000 nic salts makes a solid pairing, pick up a selection through our 10 nic salts for £16 deal to find your preferred flavour.
