Clear Display with Simple, Everyday Control

The Caliburn G4 features a 0.85" HD color screen that provides clear visibility of battery life, puff count, and vaping mode. With both day and night display settings, it remains easy to read in different lighting conditions. A single multi-function button allows you to power the device on or off, adjust settings, and switch modes with straightforward, intuitive control.

Two Output Modes for Different Vaping Styles

The Uwell Caliburn G4 offers two output modes to match your preferred vaping experience. Storm Mode delivers a stronger, warmer vape with increased vapor production, while Waves Mode provides a smoother, more consistent draw for everyday use. This flexibility allows you to easily adjust performance without complex settings.

Compatible Pods with Leak-Resistant Design

The Caliburn G4 is compatible with both Caliburn GPP cartridges and previous G3 pods, making replacements simple and accessible. The side-fill design allows you to refill without removing the pod, while Uwell’s U² technology—combining ultrasonic welding and a U-shaped airflow channel—helps reduce leaking and improve overall performance.

Frequently Asked Questions

How do I use this device?

Getting Started:

  • Remove the pod from the device and fill it with e-juice. Let it sit for 3–5 minutes to allow the coil to fully saturate. To speed up the priming process, you can also take a few puffs before installing the pod back onto the device.
  • Install the pod into the device and press the button 5 times quickly to turn it on.
  • You can start vaping by either pressing the button or simply inhaling.
  • The side lever controls your airflow.

Menu Settings:

  • To access the menu settings, press the button 4 times quickly.
  • A single press will toggle through the options.
  • A long press will confirm your settings.

Storm Mode VS Waves Mode:

  • Waves Mode provides a smooth and cooler vaping experience.
  • Choose Storm Mode for a higher wattage, more flavorful, and warmer vape. The downside to this setting is faster battery and e-juice consumption.

How do I lock or unlock the Caliburn G4?

Press the button 2 times quickly to lock or unlock the device.

How long do these pods last?

Uwell doesn’t officially specify the lifespan of Caliburn GPP pods, users suggest they typically last between 20–30mL of e-juice.

Pod longevity can vary depending on factors such as wattage settings, e-liquid flavor and sweetness, nicotine strength, and how the device is stored.
