Whether you're new to vaping or looking to upgrade your current setup, the Caliburn G4 is a solid choice. In this review, we’ll take an in-depth look at its features, performance, and why it stands out in the crowded pod system market.

Product Introduction and Specs

The UWELL Caliburn G4 Pod Kit [CRC] is a refillable closed pod system designed for both beginners and experienced vapers. This pod system is powered by a built-in 1300mAh battery, which provides ample power to last throughout the day. It features an adjustable output range of 5W to 35W, giving users the flexibility to adjust the device to their preferred power settings. The device is compatible with the Caliburn G3 Replacement Pods, which come in two resistance options: 0.4Ω and 0.9Ω, allowing you to customize your vaping experience further.

The Caliburn G4 is equipped with two unique modes, Storm Mode and Wave Mode, which offer different power delivery patterns to enhance your vaping experience. Whether you prefer a smooth and steady draw or a more powerful hit, these modes provide flexibility and personalization. The pod system is constructed with a durable combination of PCTG, ABS, and aluminum alloy materials, ensuring it is both lightweight and resistant to damage. With its ergonomic design, adjustable airflow, and a built-in clear-view juice window, the G4 is a device that stands out in both functionality and aesthetics.

Design and Build Quality

The UWELL Caliburn G4 features a sleek, modern design that’s both compact and portable. It’s available in a range of colors to suit different styles, including:

• Flamingo Red
• Glacier Blue
• Gunmetal Grey (Dark Grey)

With dimensions of 26 x 15.65 x 111.98 mm and weighing just 54.7g, the G4 is lightweight and comfortable to carry around. Its high-quality construction ensures durability, while the smooth finish and ergonomic design make it a pleasure to hold. The pod system also features a clear-view juice window, allowing you to easily monitor your e-liquid levels and avoid dry hits.

Performance and Vapor Quality

The performance of the UWELL Caliburn G4 is nothing short of impressive. The device delivers excellent vapor production and rich, full-bodied flavor, thanks to the PRO-FOCS 4.0 technology integrated into the G3 replacement pods. This technology enhances the flavor experience by maintaining the integrity of your e-liquids and providing a consistent, smooth draw every time. The adjustable airflow allows you to fine-tune your draw, whether you prefer a tight MTL (Mouth-to-Lung) hit or a looser, more open RDL (Restricted Direct-Lung) draw.

Additionally, the device offers two output modes: Storm Mode and Wave Mode, which give you more control over your vaping experience. Storm Mode provides a more intense, powerful hit, while Wave Mode offers a smoother and gentler draw. Whether you're in the mood for a boost or a relaxed session, the G4 has you covered.

Battery Life and Charging

The Caliburn G4 is powered by a built-in 1300mAh battery, which is more than enough for a full day of vaping, depending on your usage. The device charges via USB Type-C, providing fast and convenient recharging with a 2A charging speed. This ensures that you spend less time waiting for your device to charge and more time enjoying your vape.

For those who use their pod system frequently, the G4 offers sufficient battery life to last throughout the day, and with the fast-charging capabilities, you can quickly get back to vaping. The G4’s battery indicator on the screen will help you keep track of your charge levels, preventing any surprises when your battery runs low.
