Uwell - Caliburn G4 Pro - E-Cigarette - Grey
Delivery Time 1-3 working days
The Uwell Caliburn G4 Pro E-Cigarette Kit in Gray combines a powerful 1,800 mAh battery with two high-quality pods and a modern user interface. With a maximum output power of 35 watts and a 2.51-inch color touch display, you can conveniently adjust the settings. The three output modes Storm, Waves, and Custom allow you to control your vaping behavior precisely. Thanks to optional automatic draw, side airflow control, and a convenient side-filling system, this pod system can be used flexibly and easily in everyday life. The compatibility with the Caliburn G3 Pods also expands the possibilities.
Uwell Caliburn G4 Pro Battery and Operation in Detail
The Caliburn G4 Pro Battery is the heart of the kit. With its compact dimensions of 120.7 x 30 x 18.8 mm and a weight of only 78 g, it offers a good balance of performance and portability. The 1,800 mAh battery capacity ensures long runtimes, while the charging process via a USB-C port with DC 5V/2A is quickly completed. The large, colored 2.51-inch display with touchscreen allows for intuitive control, complemented by six selectable UI themes. With the optional draw activation, you can decide whether to start by pressing a button or by direct draw. A side airflow control allows for individually adjustable draw resistance, and the integrated viewing window provides information on the remaining liquid level at all times.
Innovative Power Modes for Customized Vaping
In addition to the proven output modes Storm and Waves, the G4 Pro offers a Custom mode that allows you to precisely adjust the power curve to your preferences. In Storm mode, you get direct and constant power output, while Waves ensures even flavor development with pulsating wattage output. In Custom mode, you determine how much power is delivered at the beginning, in the middle, and at the end of a draw. For example, you can choose a more intense power level in the first section and then taper off more gently – a feature that is rarely found in compact pod systems.
Caliburn G4 Pods, Compatibility, and Package Contents
The set includes two Caliburn G4 Pods with a 3.0 ml tank capacity and built-in coils. The pre-installed pod with 0.4 ohm resistance is designed for direct lung vaping (DL), while the supplied 0.6-ohm variant is suitable for restricted direct-to-lung vaping (RDL). Refilling is convenient via a side-filling system. A particular strength is the backward compatibility with pods from the Uwell Caliburn G3 series, allowing you to continue using older pods. In addition to the battery and the two pods, the package also includes a user manual, so you can start right away. The gray color scheme gives the device a simple, modern look.

Uwell
Uwell has been building e-cigarettes and atomisers since 2015. The brand is known for its Caliburn pod kits; alongside them come the Typhos devices, the Valyrian tank and pods, coils and empty tanks as refills.
Caliburn, Whirl, Typhos or Valyrian
| Series | Device | Draw |
|---|---|---|
| Caliburn G3, G4, G4 Mini, G4 Pro, G5 | compact pod kit with refillable pod | MTL, partly RDL |
| Whirl F | pod kit | MTL |
| Typhos, Typhos SE | pod mod with a larger battery and more power | RDL to DL |
| Valyrian IV | clearomiser with 510 thread for mods | DL |
RDL (restrictive direct lung) sits between the two basic styles: you draw straight into the lungs, but against noticeable resistance. The lower the coil resistance, the more power the device needs and the more open the draw.
