The Uwell Caliburn G4 Pro is the flagship of Uwell's Caliburn pod line, and it arrives loaded with features that set it apart from everything else in the range. A 1800mAh battery, 35W maximum output, a full touchscreen interface and stepless airflow control place this firmly in premium territory. At KSh 5,500, the question is whether it justifies the price tag. Here is what it brings to the table.
1800mAh Battery
The G4 Pro packs the largest battery in the current Caliburn line at 1800mAh. For a pod kit of this size, that is a substantial amount of power. Most users will get a full day of regular use from a single charge, with heavier users likely making it well past midday before reaching for a USB-C cable. The jump from the G5 Lite SE's 1600mAh to the G4 Pro's 1800mAh may look modest on paper, but in daily use, every extra milliamp-hour counts.
35W Output
Maximum output sits at 35W, matching the G5 Lite SE. The G4 Pro uses Smart Mode to read the installed pod's coil resistance and automatically adjust the wattage. This ensures the coil operates within its optimal range without requiring you to tinker with settings manually. The result is consistent performance whether you are using a GPP pod or a G3 pod.
Touchscreen Display
The most visually striking feature of the G4 Pro is its touchscreen. The display (reported at 2.51 inches, though this figure has not been independently verified against Uwell's official spec sheet) replaces the button-based controls found on other Caliburn models. Through the touchscreen, you can view battery level, adjust settings and monitor your usage. It is responsive and adds a layer of interactivity that no other pod kit in this price range offers at Vapesoko.
Stepless Airflow Control
Unlike devices that offer two or three fixed airflow positions, the G4 Pro features stepless airflow adjustment. This means you can fine-tune the draw resistance to any point along the full range, from a tight mouth-to-lung draw through to a looser, more open pull. The control is smooth and stays where you set it, so you can find your preferred draw and leave it there.
Dual Pod Compatibility: GPP and G3
One of the G4 Pro's strongest practical advantages is its compatibility with both GPP pods and the older G3 pod line. This gives you two pod ecosystems to draw from, broadening your options for coil resistance and availability. If your preferred local shop is out of one type, the other will work just as well in the same device.
Both pod types hold 3ml of e-liquid and use a side-fill design. Replacement GPP pods are available at Vapesoko for KSh 2,000.
Build Quality and Dimensions
The G4 Pro has a reported length of 120.7mm (this figure appears in existing product listings but has not been verified against Uwell's official specifications). It is compact enough for pocket carry while still accommodating the larger battery and touchscreen. The build feels solid in hand, with a fit and finish that reflects its position at the top of the Caliburn range.
Pairing with E-Liquids
The G4 Pro's pod options make it compatible with a range of e-liquid types. For nicotine salts, Vapesoko stocks Ultimate Salts 30ml at 50mg for KSh 2,000. For freebase liquid, Ultimate Juice 120ml is available in 3mg, 6mg and 12mg at KSh 2,300, in a 70/30 VG/PG blend with 12 flavours including Guava.

The Draw: MTL and RDTL
The stepless airflow control is where the G4 Pro earns its name. Close the airflow ring down, and you get a firm, tight mouth-to-lung draw that suits high-strength nicotine salts. Open it halfway, and you move into restricted direct-to-lung territory, where the vapour is warmer, the clouds are denser, and the flavour opens up. Open it fully, and the draw becomes loose and airy, closer to a standard DTL inhale.
Most vapers will settle somewhere in the middle third of the airflow range and leave it there. The fact that you can adjust the draw without swapping pods or coils is what makes this a genuinely versatile device. One kit covers the range that would otherwise require two separate devices.
The Touchscreen in Daily Use
On a pod kit this size, a touchscreen is unusual. In practice, it works well for checking battery level at a glance and scrolling through basic settings. The display is bright enough to read in daylight and responsive enough that you do not end up jabbing at it repeatedly.
Where it matters most is the first few minutes after unboxing, when you are setting up the device. After that, most vapers interact with the screen only to check the battery. The touchscreen is not a reason to buy the G4 Pro on its own, but it adds a layer of polish that simpler pod kits lack.
Running Costs
The G4 Pro kit is KSh 5,500. After the initial purchase, the main ongoing expense is replacement pods. GPP pods cost KSh 2,000 per pack, and each holds 3ml. A single pod typically lasts one to two weeks depending on usage and liquid sweetness.
A 30ml bottle of nicotine salt at KSh 2,000 fills the pod ten times, covering roughly two to three weeks of moderate use. Over a month, expect to spend around KSh 2,000 to KSh 4,000 on pods and a similar amount on liquid. That puts the total monthly running cost in the KSh 4,000 to KSh 8,000 range depending on how heavily you vape.
Compared to disposables at KSh 2,000 to KSh 3,000 each, the G4 Pro's higher upfront cost pays for itself within the first month or two of refillable use.
What Sets It Apart from the G5 Lite SE and the G4
The Caliburn range offers several options at different price points. Here is how the G4 Pro compares to its closest siblings:
- Caliburn G5 Lite SE (KSh 5,000): A strong device in its own right, with a 1600mAh battery and 35W Smart Mode. It uses GPP pods only, has no airflow control and no screen. If you want a straightforward, set-and-forget pod kit, the G5 Lite SE delivers excellent value. The G4 Pro adds 200mAh more battery, a touchscreen, stepless airflow and dual pod compatibility for KSh 2,000 more.
- Caliburn G4 (KSh 5,500): The G4 shares the same 35W Smart Mode and supports GPP pods. Its 1300mAh battery is smaller than both the G5 Lite SE and the G4 Pro. It lacks the touchscreen and stepless airflow. If you want more features than the G5 Lite SE but the G4 Pro is beyond budget, the G4 is the middle ground.
The G4 Pro's combination of the largest battery, dual pod support, touchscreen and stepless airflow makes it the most capable Caliburn in the range. Whether that justifies the price premium depends on how much you value adjustability and screen feedback.
Who the G4 Pro Suits
The G4 Pro is for vapers who want control. If you like dialling in your airflow, switching between MTL and RDTL depending on the moment, and having a visual readout of your battery and settings, this is the device for you.
It also suits vapers who already own G3 pods from an older Caliburn and want to carry those pods over to a new device. Dual pod compatibility saves money during the transition.
If you prefer simplicity and do not need airflow control or a screen, the G5 Lite SE at KSh 5,000 offers most of the performance at a lower price. If you want the most capable Caliburn e-liquid experience Vapesoko stocks, the G4 Pro is it.
