Uwell Caliburn G4 Pro Pod Kit
The Uwell Caliburn G4 Pro is a refillable pod kit powered by a built-in 1800mAh battery with adjustable output up to 35W. Its large 2.51-inch touchscreen provides direct access to wattage, vaping modes, themes, puff information and device settings.
The device uses Uwell’s Caliburn GPP cartridge platform and supports both MTL and RDL vaping. Stepless airflow adjustment lets the draw move from tight and restricted to more open, while Storm, Waves and Custom modes provide different approaches to power delivery.
Pure Vaper’s supplied range includes eight colour options.

1800mAh Battery & Up To 35W
A built-in 1800mAh battery gives the G4 Pro more capacity than the standard Caliburn G4, while output can reach 35W.
Power can be adjusted through the touchscreen, allowing the device to accommodate different compatible GPP pod resistances and both MTL and RDL setups.
2.51-Inch Smart Touchscreen
The G4 Pro is Uwell’s first Caliburn device built around a full 2.51-inch touchscreen. Core functions such as wattage adjustment, output-mode selection and puff-counter reset can be accessed directly from the display.
The interface also includes six themes, adjustable brightness, screen timeout controls, battery-saver settings and eight supported languages.
Storm, Waves & Custom Modes
Storm & Waves
Storm Mode is designed around a stronger initial power delivery, while Waves Mode provides a smoother power profile across the draw.
Custom Mode
Custom Mode lets you adjust output separately at the start, middle and end of each puff, providing more detailed control over the power curve.
Caliburn GPP Pod Platform
The G4 Pro is compatible with Uwell’s Caliburn GPP cartridge platform, including previous and upgraded GPP cartridges.
The integrated-coil cartridges are replaced as complete pods when the coil reaches the end of its usable life. Different GPP resistances allow the device to cover both tighter MTL and more open RDL vaping styles.
UΒ² Anti-Leak & Top-Fill Design
Uwell’s upgraded GPP cartridges use its UΒ² anti-leak architecture, combining ultrasonic welding and an internal channel design intended to reduce leakage.
Uwell also states that the upgraded cartridges can be refilled without removing the pod from the device, reducing the number of steps required for routine refilling.
Stepless Airflow For MTL & RDL
The airflow control is continuously adjustable rather than limited to fixed preset positions.
This allows the draw to move from a tighter mouth-to-lung inhale towards a more open restricted-direct-to-lung setup, depending on the GPP cartridge installed.
Caliburn GPP Replacement Pod Compatibility
The G4 Pro uses the Uwell Caliburn GPP pod platform. Uwell confirms compatibility with both previous and upgraded GPP cartridges, giving users several resistance options across the wider platform.

Why Choose The Uwell Caliburn G4 Pro?
The G4 Pro adds a much larger touchscreen interface to the Caliburn platform while keeping the familiar refillable GPP cartridge system. Wattage, modes, puff data and device settings can all be managed from the display.
Its 1800mAh battery and 35W ceiling provide more headroom than simpler fixed-output pod kits, while stepless airflow and multiple compatible GPP resistances let the same device cover both MTL and RDL use.
Custom Mode is also unusual for a compact pod device because it lets the power curve be adjusted across different stages of an individual puff rather than applying one static output profile.
