Design & Build Quality

The G4 PRO looks modern and solid. Uwell uses aluminum and high-quality plastics, making the device feel sturdy yet light enough for all-day carry. The slim, pocket-friendly body is available in both classic and vibrant colors. The standout feature is the touchscreen, designed with a single-tap interface that lets you quickly adjust basic settings without navigating menus or using multiple buttons. This makes the device user-friendly for beginners, while still offering customization options for experienced users.

Pods and Coils Specifications

The G4 PRO is compatible with Uwell’s GPP/G3 style pods. The 2 ml version typically features top-fill pods that are TPD/CRC compliant and designed to minimize leaks. Available coil options for the G4 PRO usually include 0.4 Ω and 0.6 Ω mesh coils, offering a balance between flavor and vapor production. Mesh coils are favored for their even heating and the fuller, more consistent taste they provide compared to traditional round wire coils. The G4 PRO is a higher-end pod device in the Caliburn line, aimed at people who want good flavor, simple control, and long battery life without the complexity of a full mod.

Choosing the Right Pod or Coil

If you prefer mouth-to-lung (MTL) draws, opt for the higher-ohm pod or coil. For a looser, more vapor-rich draw (restricted direct-to-lung or RDL), the lower-ohm pod is better. Uwell’s pods are generally durable and designed for easy click-in and removal, making maintenance straightforward.

Performance – Flavor and Vapor Quality

Flavor is the G4 PRO’s prominent feature. Uwell’s FOCS flavor technology and mesh coil design deliver consistently clean, prominent taste, especially with high-PG or balanced e-liquids. At low to mid wattages (where most users will likely operate this device), the flavor remains bright and crisp, and the vapor is smooth without harshness. The G4 PRO supports up to 35 W, offering more power than many simple pod kits. This added headroom is beneficial for those who prefer warmer, fuller hits.

Customizable Draw – MTL and RDL Experience

The new Caliburn G4 PRO also features adjustable airflow. Combined with two coil options, this lets you customize your draw from tight MTL to a looser RDL experience. Overall, expect outstanding flavor and satisfying vapor production for a pod kit—suitable for daily use, though not designed for cloud chasing.

Battery & Charging

The G4 PRO’s 1800 mAh internal battery is generous for a pod kit. In practice, this means that most users can expect a full day or more of normal use on a single charge, depending on their chosen wattage and usage frequency. Uwell has also equipped the device with fast charging, typically via USB-C on recent models, making recharging quick and convenient. This larger battery is one of the most significant upgrades over smaller Caliburn models.

A few tips: using higher wattage and taking long draws will reduce the battery life more quickly, and it is generally not recommended to use the device while charging to preserve battery health. Overall, for everyday use, the battery is reliable and eliminates the need for frequent recharging.

Screen & Controls

Uwell’s touchscreen UI is designed for simplicity: easily change wattage, switch modes (Wave, Storm, Custom), check puff count, and toggle day/night themes with a tap. The interface is more intuitive than the small button clusters found on many other pod kits. However, if you prefer devices without screens, the G4 PRO’s touch UI may seem unnecessary, but most users find it convenient after giving it a try.

Ease of Use & Maintenance

The G4 PRO is designed for ease of use. Pods click in securely, refilling is simple, coil swaps are quick, and Uwell’s leak-prevention design minimizes mess. Cleaning is straightforward: wipe the pod contacts, rinse or replace pods when flavor fades, and keep device ports free of dust. For best performance, change coils before a burnt taste develops and use e-liquids that match the coil’s recommended range.

Pros & Cons

Pros

• Excellent flavor for a pod kit; mesh coils perform well.
• Long battery life (1800 mAh) and fast charging.
• Smart touchscreen is intuitive and quick to use.
• Leak-resistant, refillable 2 ml pods (TPD/CRC compliant).

Cons

• Touchscreens can be more fragile than button controls if handled roughly.
• Not designed for big-cloud users; it favors flavor over huge vapor.
• Pod capacity (2 ml) can mean more frequent refills compared with larger tanks.

Who Should Buy It?

Choose the Caliburn G4 PRO if you want a reliable daily pod system that delivers excellent flavor, long battery life, and simple touch controls. It’s perfect for vapers who prioritize taste and convenience, whether you are a beginner seeking an easy-to-use device with flexible options or an experienced user looking for a compact backup with solid performance. If you prefer hardcore sub-ohm or cloud-chasing setups, this isn’t the device for you. But for most everyday vapers, the G4 PRO is a practical, well-balanced option.

Various Color Options of Uwell Cliburn G4 PRO

The G4 Pro is available in eight vibrant colors, including Desert Gold, Frost White, Stripe Black, Pearl Silver, Iron Gray, Fantasy Pink, Light Green, and Ink Blue.

Conclusion

Uwell’s Caliburn G4 PRO builds on the strengths of the Caliburn family, simple operation and impressive flavor, by introducing a larger battery and a user-friendly touchscreen. It doesn’t aim to be a full mod, nor does it need to. Instead, it consistently delivers flavorful hits in a compact, easy-to-use kit. If you are seeking reliable performance without a steep learning curve, the G4 PRO is a solid choice.
