Uwell Caliburn G3 Pro

The Uwell Caliburn G3 Pro is a refillable pod system that Uwell announced on July 23, 2024 as the first vape device with a full-screen display, with adjustable output up to 35 W and support for G Pod Platform (GPP) cartridges.1 It runs on the owner's own freebase or nic salt e-liquid, so there is no puff count or set nicotine strength.

Caliburn G3 Pro Screen and Controls

The Caliburn G3 Pro screen is a full-screen dynamic display that shows battery, wattage and coil resistance, and Uwell's G3 Pro page calls it the first Caliburn with a full-screen display.2 Button presses select between auto and air activation, per the same page.

Wattage is adjustable up to 35 W, and Versed Vaper's review gives the range as 5 to 35 W.3

Caliburn G3 Pro Battery and Charging

The Caliburn G3 Pro battery is 1,000 mAh according to reviewer and reseller sources; Uwell's page text does not state it.34 It charges over 2A USB-C.

Uwell's press release lists overheat, short-circuit and low-voltage protection.1 Versed Vaper's January 2025 review also covers a G3 Pro KOKO variant with a larger 1,250 mAh battery.3

Caliburn G3 Pro Pods and Airflow

The Caliburn G3 Pro takes Caliburn G3 cartridges, which Uwell lists at 0.4 ohm, and works with the wider G Pod Platform.2 Versed Vaper says the US kit shipped with side-fill pods in 0.6 and 0.9 ohm.3 Sources disagree on the pod capacity and on the device's size, so neither is given here.

It was also the first Caliburn with a fine-tuning, stepless airflow valve, according to Uwell.1

Caliburn G3 Pro vs Caliburn G5

The Caliburn G3 Pro and the newer Caliburn G5 both reach 35 W and take GPP cartridges, but the G5 carries a 1,600 mAh battery against the G3 Pro's 1,000 mAh.5

Uwell calls the G3 Pro the first Caliburn with a full-screen display, while the G5's screen runs a themed interface matched to each color.6

The Caliburn G3 Pro can't be legally sold under federal rules without an FDA marketing order, and it had none as of October 2026.7 The FDA's April 27, 2020 warning letter to Uwell named the original Caliburn kits, not the G3 Pro, which came four years later.8
