📱 2.51” Touchscreen Interface
The large 2.51-inch touchscreen gives the Caliburn G4 Pro a highly interactive control system, allowing essential settings and device information to be accessed directly through the touch interface.
Users can select between 6 visual themes, choose from 8 interface languages, and personalize the device name for a more customized experience.
🌊 Storm, Waves & Custom Modes
The G4 Pro provides three output profiles for adjusting the character of its power delivery.
1. Storm Mode: Provides a stronger and more impactful output profile.
2. Waves Mode: Delivers smoother and more balanced power delivery.
3. Custom Mode: Allows greater personalization of wattage behavior according to preference.
These selectable modes provide more flexibility than a basic fixed-output pod system and allow performance to be adapted to different preferences.
✨ Pro-FOCS 4.0 Flavor Technology
Uwell integrates Pro-FOCS 4.0 into the Caliburn G4 Pro platform to support consistent flavor performance across compatible cartridges.
Combined with built-in mesh coil pods and adjustable power, the system provides a balanced combination of flavor and vapor during regular use.
💨 Stepless MTL to RDL Airflow
The stepless airflow slider provides fine airflow adjustment rather than limiting the device to several fixed positions. This allows greater control over draw resistance.
Restricting the airflow creates a tighter MTL-style draw, while opening it provides a looser RDL-style experience.
💧 Pod Filling & Priming
Compatible cartridges feature built-in mesh coils and a convenient filling system. When using a fresh pod, proper priming allows the internal wick to absorb e-liquid before the coil is heated for the first time.
1. Open the pod filling port.
2. Fill the cartridge carefully without overfilling.
3. Close the filling port securely.
4. Allow the filled pod to sit for approximately 10 minutes.
5. Install the pod and use an appropriate wattage for its resistance.
Allowing the pod to rest after filling helps the wick inside the cartridge become properly saturated before the first use.
🔋 1800mAh Battery & USB-C 2.5A Charging
A built-in 1800mAh high-density battery provides substantial battery capacity while maintaining the portable Caliburn form factor.
The device supports USB-C charging at up to 2.5A when connected to compatible charging equipment.
🛡️ U² Leak-Resistant Design
The Caliburn G4 Pro incorporates Uwell's U² leak-resistant engineering alongside its compatible cartridge design to help manage condensation and reduce routine leakage around the pod connection.
A distinctive droplet-shaped viewing window also makes it easier to check the remaining e-liquid level without removing the cartridge.

How to Use & Tips
📦 Uwell Caliburn G4 Pro 35W Pod System – Pod System Guide for Better Daily Performance
Choosing the right nicotine strength and coil resistance in a pod system can affect flavor quality, coil life, and day-to-day comfort. This guide is designed to help you start correctly and avoid common problems.
⭐ Tips That May Help Improve Coil Life & Daily Performance
- Prime properly: After the first fill, leave the pod for 5–10 minutes before taking the first puff.
- Keep liquid above the cotton ports: Letting the pod run too low may dry the coil and reduce performance.
- Use appropriate charging: A computer USB port or a low-power charger such as 5W/1A is often preferable to high-power fast chargers.
💡 Quick tip: Not sure which resistance suits your device? Check the old coil — the number is often printed on it, or ask our support team.
🎯 Nicotine Guide by Smoking Habit
| Smoking Habit | Common Strength | Draw Style |
|---|---|---|
| Less than 10 cigarettes/day | 6–12mg Freebase | Calm MTL |
| 10–20 cigarettes/day | 12mg Freebase or 20mg Salt | A suitable alternative in many cases |
| 20+ cigarettes/day | 20–35mg Salt with caution | Better suited to more experienced users |
💡 If you feel dizzy or get a headache, your nicotine strength may be higher than you need and can often be reduced gradually.
⚡ Coil Resistance by Draw Style
- 0.8Ω – 1.2Ω: Tight MTL draw with a more cigarette-like feel – often suitable for salt nicotine and 12mg freebase.
- 0.4Ω – 0.6Ω: Looser RDL draw – often more suitable for 6mg freebase and increased vapor.
🔥 Common Issues & Quick Fixes
• Burnt taste: Priming may not have been enough, or the liquid level may be too low.
• Gurgling or leaking: This may happen with overly hard draws or unsuitable airflow settings.
• Device not firing: Cleaning the contact points with a dry cotton swab may help.
📋 Extra Tips
- Leave 15–20 seconds between puffs when possible.
- Use 50/50 VG/PG e-liquid with most pod systems.
- Replace the coil when flavor drops clearly or changes noticeably.

💧 For a More Comfortable Experience
• Drinking water regularly may help reduce dryness.
• Dizziness or headache can be a sign that your nicotine strength is too high.
• Leaving 15–20 seconds between puffs may help the coil cool and keep flavor more stable.
