The Uwell Caliburn G4 Pro Kit is a touchscreen refillable pod system for adult vapers who want more control from a compact device. It combines a 1800mAh battery, a 2.51-inch touch display and adjustable output with two supplied Caliburn GPP pods for both mouth-to-lung (MTL) and restricted-direct-to-lung (RDTL) vaping.

Which pod should I use?

The 0.9Ω pod provides the tighter MTL draw and is well suited to 50VG/50PG nic salt e-liquid. The 0.4Ω pod creates a warmer, airier RDTL vape with more vapour; use a lower nicotine strength and begin at a modest output. Replacement options are available on the Uwell Caliburn GPP pods page.

Touch controls and output modes

The touchscreen can adjust wattage, switch modes, reset the puff count and change display settings. Smart Mode simplifies setup around the installed pod. Waves Mode is designed for smoother delivery, Storm Mode produces a more immediate output and Custom Mode lets you shape the power at the start, middle and end of a puff. Begin conservatively whenever changing modes or fitting a new pod.

Filling and anti-leak design

The upgraded GPP pods can be refilled without removing them from the device and use Uwell's U² leak-resistant construction. Fill carefully, close the port and leave a new cartridge to prime for several minutes.

Screen settings and accessibility

The interface supports eight languages and provides controls for screen brightness, timeout, animation and battery-saving behaviour. Six themes personalise the display without changing the vaping performance. The touch controls reduce reliance on repeated button sequences, but the device should still be locked before carrying.

The clear pod and on-screen information make liquid, resistance and battery status easier to monitor. Clean the pod contacts regularly and replace a cartridge if the seal is damaged or performance declines.
