UWELL directly confirms the 2000mAh battery, 35W maximum output, touchscreen platform, three output modes, five UI themes, and compatibility with both earlier and upgraded GPP cartridges.
2000mAh Mega Battery
The G4 Pro KOKO uses a 2000mAh internal rechargeable battery, substantially increasing battery capacity compared with the previous G3 Pro KOKO. UWELL promotes the device for extended runtime and advertises up to 10 days under its own low-use testing conditions. Actual battery life depends heavily on pod resistance, selected power, puff duration, and frequency of use.
A higher-output 0.4Ω setup will normally consume more battery than a lower-power 0.9Ω or 1.2Ω MTL configuration.
Up to 35W Output
UWELL officially lists the G4 Pro KOKO with up to 35W power output.
This gives the device enough flexibility to support:
- More open RDL vaping
- Standard MTL
- Tight MTL
- Different GPP resistance options
The final power setting should always remain within the supported range of the installed cartridge.
Smart Touchscreen Interface
The G4 Pro KOKO is UWELL’s first KOKO model with a dedicated touchscreen interface. Core functions are accessible through touch controls rather than relying entirely on small buttons or a simple indicator screen.
The interface provides access to functions such as:
- Output mode
- Device settings
- Screen brightness
- Screen timeout
- Animation settings
- Battery Saver
- System reset
- Language selection
- UI customization
UWELL also allows users to activate a cleaner UI and give the device a custom name.
Five Blind Draw UI Themes
The G4 Pro KOKO includes five collectible UI themes that are unlocked through UWELL’s interactive Blind Draw system.
This is mainly a visual personalization feature and does not change cartridge compatibility or nicotine delivery.
8 Interface Languages
UWELL currently lists eight supported interface languages:
- English
- Arabic
- Spanish
- French
- Russian
- Italian
- German
- Indonesian
Arabic interface support is particularly relevant for UAE users.
Three Output Modes
The G4 Pro KOKO introduces three distinct output modes.
Storm Mode
UWELL positions Storm Mode for a quicker and stronger initial output response.
It may suit users who prefer a more immediate power delivery.
Waves Mode
Waves Mode is designed around smoother and more consistent output through the puff.
Customize Mode
Customize Mode gives users greater control over the way power is delivered, adding another level of adjustment beyond simple wattage selection.
These modes are one of the biggest software upgrades over the G3 Pro KOKO.
Full CALIBURN GPP Compatibility
The G4 Pro KOKO belongs to UWELL’s G Pod Platform, or GPP.
UWELL states that the device is fully compatible with both previous-generation and upgraded GPP cartridges. The wider GPP ecosystem currently supports the CALIBURN G3, G4, and G5 families.
Current resistance choices include:
- 0.4Ω
- 0.6Ω
- 0.9Ω
- 1.2Ω
Current GPP Pod Guide
| Resistance | General Style | Typical Use |
|---|---|---|
| 0.4Ω | RDL | Higher output, more open draw |
| 0.6Ω | RDL / Loose MTL | Balanced performance |
| 0.9Ω | MTL | More restricted draw |
| 1.2Ω | Tight MTL | Lower-power vaping |
UWELL positions the current GPP family from RDL at the lower resistances through tighter MTL at the higher resistances.
0.4Ω GPP Cartridge
The common international G4 Pro KOKO kit includes a 0.4Ω GPP cartridge. Multiple current kit listings document a 3ml 0.4Ω pod in the standard package.
The 0.4Ω option is best suited to:
- RDL vaping
- Higher output
- More open airflow
- Greater vapour production
- Lower-strength compatible e-liquid
0.6Ω GPP Cartridge
A 0.6Ω GPP cartridge is also commonly supplied with the international kit.
It provides a more balanced setup between RDL and loose MTL.
This pod may suit users wanting:
- Moderate power
- More restricted airflow than 0.4Ω
- Nicotine salt or compatible freebase
- Balanced vapour output
Optional 0.9Ω GPP Pod
The 0.9Ω GPP cartridge is fully compatible even though it is not normally one of the two cartridges in the standard international G4 Pro KOKO package.
It is better suited to:
- MTL vaping
- Lower output
- More restricted airflow
- Compatible nicotine salt
Optional 1.2Ω GPP Pod
The 1.2Ω cartridge is the highest-resistance current GPP option and is designed for a tighter MTL configuration.
It may suit users looking for:
- Tight MTL
- Lower-power use
- Reduced vapour output
- Compatible nicotine salt e-liquid
3ML GPP Cartridge Capacity
UWELL’s current GPP platform lists 3ml side-fill and 3ml top-fill cartridges in 0.4Ω, 0.6Ω, 0.9Ω, and 1.2Ω versions.
The standard international G4 Pro KOKO package is also widely documented with 3ml cartridges.
Smaller regional versions exist, including:
- 2.5ml
- 2ml TPD versions
Therefore, Shopify capacity should match the actual package being sold.
Top-Fill and Side-Fill Compatibility
The current GPP ecosystem contains both:
- Side-refill cartridges
- Top-refill cartridges
and the G4 Pro KOKO supports both earlier and upgraded GPP cartridge generations.
This means customers are not restricted to one filling format.
The exact pods included in the package should still be listed separately from compatible replacement cartridges.
U² Anti-Leak Technology
UWELL’s current GPP cartridges use U² Anti-Leak Technology, combining ultrasonic welding with a U-shaped airflow channel.
UWELL claims this design improves leak protection by 150% against its referenced previous construction. This is a manufacturer test claim and does not mean that condensation or leakage is impossible.
For better maintenance:
- Keep the fill port closed
- Avoid overfilling
- Wipe condensation from pod contacts
- Replace physically damaged cartridges
- Keep the device away from excessive heat
PRO-FOCS Flavour Technology
Current GPP cartridges use PRO-FOCS flavour optimization technology and support different nicotine forms, including freebase and nicotine salts.
The exact flavour performance and cartridge lifespan vary according to:
- E-liquid sweetness
- Resistance
- Output mode
- Wattage
- Puff frequency
- Proper priming
Stepless Adjustable Airflow
The G4 Pro KOKO has a physical adjustable airflow system, commonly described as stepless airflow control.
More Restricted Airflow
Better suited to:
- 0.9Ω
- 1.2Ω
- MTL vaping
More Open Airflow
Better suited to:
- 0.4Ω
- 0.6Ω
- RDL or loose MTL
Using pod resistance and airflow together gives the device a wider range than fixed-airflow pod kits.
Nicotine Salt and Freebase Compatibility
UWELL’s official GPP documentation confirms support for both freebase nicotine and nicotine salt e-liquid.
A basic guide is:
0.4Ω
Better suited to:
- RDL
- Lower-strength compatible e-liquid
- Freebase
- Lower-strength nic salt where appropriate
0.6Ω
Suitable for:
- RDL
- Loose MTL
- Freebase
- Nic salt
0.9Ω
Better for:
- MTL
- Lower power
- Nic salt
1.2Ω
Better for:
- Tight MTL
- Low power
- Nic salt
Nicotine concentration should always be chosen according to output and existing nicotine use.
USB Type-C Charging
Current international specifications list the G4 Pro KOKO with USB Type-C charging at 5V/2A.
For charging:
- Keep the Type-C port clean and dry.
- Use compatible charging equipment.
- Place the device on a stable surface.
- Avoid charging a damaged device.
- Disconnect it once charging is complete.
Battery Saver Mode
UWELL includes a dedicated Battery Saver setting in the touchscreen menu.
The device also allows adjustment of:
- Screen brightness
- Screen timeout
- Animation
- Other interface functions
Reducing screen brightness and animation activity can help reduce non-vaping power consumption.
Current G4 Pro KOKO Colours
The current widely listed colour range includes:
- Coral Pink
- Cosmic Gray
- Crystal White
- Desert Gold
- Glass Blue
- Light Green
- Mirror Silver
- Waves Black
Only publish colours that match your current UAE inventory.
Compact KOKO Design
The G4 Pro KOKO retains UWELL’s compact square-style KOKO shape while housing its larger 2000mAh battery and touchscreen.
Current product listings commonly specify approximate dimensions of:
85.8 × 50 × 23mm.
The body is considerably shorter than a traditional pen-style CALIBURN device.
What Comes in the Box?
The standard international package is commonly documented as:
- 1 × Uwell Caliburn G4 Pro KOKO Device
- 1 × 3ml 0.4Ω CALIBURN GPP Cartridge
- 1 × 3ml 0.6Ω CALIBURN GPP Cartridge
- 1 × User Manual
Regional kits may vary.
Check the actual UAE package before advertising a charging cable or different pod combination as included.

The KOKO version has:

The G4 Pro KOKO remains distinctive because of its touchscreen interface and large 2000mAh battery.
