Why Choose Uwell?
Uwell builds pod kits around one consistent goal: the best possible flavour from every single puff.
Uwell's PRO-FOCS 4.0 system is built into every Caliburn G3 and G4 series device.
It optimises the coil heating process to extract richer, more layered taste from every pod, whether you are using nic salts or 50/50 e-liquids.
All Caliburn G3 and G4 kits share compatibility with Caliburn GPP pods.
With four resistance options from 0.4 ohm to 1.2 ohm, you can tune your draw across tight MTL and open RDL using one universal pod across multiple devices.
Uwell's U² anti-leak system uses ultrasonic welding and a U-shaped airflow channel to reduce leaking by 150% compared to standard pod systems.
The result is a cleaner, more consistent daily experience with no wasted e-liquid and no sticky pockets.
From the draw-activated Caliburn G5 Lite SE to the touchscreen Caliburn G4 Pro and the high-puff Viscore Pro+, Uwell covers every vaping preference and experience level in one trusted brand ecosystem.

Uwell FAQs
Yes. The Caliburn G5 Lite SE and G5 Lite are both ideal for beginners. They are draw-activated with no buttons or settings to adjust. Fill the pod, click it in, and vape. Smart Mode handles wattage automatically.
Yes. Both the G3 Pro and G4 series kits use Caliburn GPP pods in 0.4, 0.6, 0.9, and 1.2 ohm options. This shared platform means you can upgrade your device without changing your pods or coils.
For most vapers switching from cigarettes or disposables, 20mg nic salt with a 0.9 or 1.2 ohm pod is the standard starting point for a tight MTL draw. For a more open RDL draw, a 0.4 or 0.6 ohm pod with 50/50 e-liquid works well across all G3 and G4 series kits.
Both use the GPP pod platform and offer up to 35W. The Caliburn G4 has a 0.85-inch HD colour screen, 1300mAh battery, and Storm and Waves modes. The Caliburn G4 Pro adds a 2.51-inch shatterproof touchscreen, a 1800mAh battery, Custom Mode power curve, and 8 language options. Choose the G4 Pro for a larger screen and more advanced controls.
Both have touchscreens, GPP pod compatibility, and Storm, Waves, and Custom modes. The Caliburn G4 Pro has a larger 2.51-inch screen and 1800mAh battery. The Caliburn G4 Pro Koko uses a 2.0-inch screen and 2000mAh battery in the more compact KOKO form factor. Choose the Koko for a smaller, pocketable build with a larger battery.
With regular use and quality nic salts or 50/50 e-liquids, most GPP pods last one to two weeks. Uwell's PRO-FOCS 4.0 and U² anti-leak system extend pod life by up to 35% compared to previous Caliburn pod generations.
