Caliburn G4 vs G4 Mini vs G4 Pro: Which Pod Vape Is Best in Canada?
Many vapers struggle to find a pod vape that balances flavor, battery life, and ease of use. The Uwell Caliburn G4 series offers three options that share the same trusted DNA but serve different needs.
Built on Pro-FOCS 4.0 flavor technology and GPP cartridge compatibility, all three devices deliver a reliable mouth-to-lung experience. In this review, you will explore the Caliburn G4, G4 Mini, and G4 Pro — covering design, performance, battery life, and key differences so you can pick the right one.
Introduction to the Caliburn G4 Series
Uwell Caliburn devices have built a strong reputation among beginner and experienced vapers alike for simple operation, reliable pods, and consistent flavor. The G4 series continues that reputation with several meaningful upgrades.
All three devices run on Pro-FOCS 4.0 flavor technology, which Uwell credits with a 35% improvement in both cartridge lifespan and flavor satisfaction compared to earlier generations. They also share GPP (G Pod Platform) cartridge compatibility — meaning G4 pods work across all three models, and are also backward-compatible with Caliburn G3 series devices.
The lineup covers three distinct profiles: the G4 for balanced everyday performance, the G4 Mini for maximum portability, and the G4 Pro for users who want a touchscreen interface and extended battery life.
What makes Uwell Caliburn G4 devices popular
Battery performance
Battery capacity ranges from 1100mAh in the G4 Mini up to 1800mAh in the G4 Pro, with the standard G4 sitting at 1300mAh. All three support USB-C fast charging, keeping downtime short during the day.
Flavor performance
Pro-FOCS 4.0 is the shared flavor engine across the entire G4 lineup. The GPP pod system uses leak-resistant U² anti-leak technology (ultrasonic welding plus a U-shaped channel design), which keeps flavor consistent and refills mess-free. Many users find that a single pod delivers reliable taste for several days before it begins to fade.
Storm Mode, Waves Mode and Custom Mode
Ease of use
All three models use top-fill GPP pods that can be replaced in seconds without removing the pod from the device. Draw activation is standard across the lineup, with button firing also available on the G4 and G4 Pro for users who prefer manual control.

The Caliburn G4 is the balanced option in the lineup. Its 1300mAh battery handles a full day of moderate vaping, and the animated color display gives clear readouts of battery level, wattage, and puff count. Adjustable airflow lets you dial in a tight MTL draw or open it slightly for a smoother restricted draw. Storm and Waves modes let you switch between an intense throat hit and a mellow, consistent puff depending on your mood.
Caliburn G4 Mini review
Caliburn G4 Mini

|---|---|
| Battery | 1100mAh |
| Max output | 35W |

| Screen | LED indicator |
| Airflow | Fixed MTL draw |

The G4 Mini strips the design down to its essentials for vapers who prioritize pocket-friendly size over advanced controls. Its 1100mAh battery is slightly smaller than the standard G4, but still handles a solid day of regular use. The simplified LED indicator replaces the full color screen, keeping the interface minimal. Storm and Waves modes are still available via a single button, and draw activation makes one-handed use effortless. Pro-FOCS 4.0 ensures the compact size doesn't compromise on flavor.

The G4 Pro is the flagship of the series. Its 2.51-inch ultra-shatterproof touchscreen is the most visible upgrade — all core functions are accessible with a single tap, and you can choose from 6 UI themes to personalize the display. The 1800mAh battery supports extended sessions, and the exclusive Custom Mode lets you fine-tune output power at the start, middle, and end of each puff for a fully personalized draw. An ergonomic contoured mouthpiece completes the experience.

Who should buy each device?
Pros and cons of the Caliburn G4 series
The G4 lineup shares several strong advantages: Pro-FOCS 4.0 flavor technology, GPP pod compatibility across all three models, USB-C fast charging, and Storm and Waves modes on every device. Pod replacement takes seconds, and the anti-leak GPP cartridges keep things clean.
The main trade-offs depend on which model you choose. The G4 Mini offers the least control — no adjustable airflow and a fixed output — which is intentional for simplicity but may frustrate vapers who like to fine-tune their draw. The standard G4's 1300mAh battery is sufficient for most users but may fall short for very heavy vapers. The G4 Pro adds the most features but comes at a higher price point and a slightly larger body.
