The Uwell Caliburn series has earned a strong name for flavor quality, reliability, and simplicity. Every new release improves airflow, coil design, and power delivery while keeping the same easy feel. The Caliburn G4 and Caliburn G4 Mini continue that legacy. Both are compact pod systems built for clean taste and steady performance. This comparison explains how they differ and which version fits your vaping style best.
Overview of the Uwell Caliburn Series
The Uwell Caliburn series started with a simple goal: to make vaping easy and enjoyable for everyone. Over the years, each version has refined that formula. The Caliburn G2 brought better airflow control. The G3 improved flavor and coil options. Now the Caliburn G4 and G4 Mini focus on smoother vapor, faster heating, and longer coil life.
Both use Uwell’s Pro-FOCS flavor system, which keeps e-liquid taste clean and balanced. These updates show how the brand continues to lead in compact pod design while maintaining reasonable prices for everyday users.
Caliburn G4 vs. G4 Mini: What Sets Them Apart?
The two models share many features but serve different types of vapers. The Caliburn G4 is slightly larger and more powerful, designed for people who prefer stronger performance and adjustable airflow. The Caliburn G4 Mini is smaller, lighter, and made for simple use on the go.

-
Mini: Completely plug-and-play—fill, flick the airflow slider, and vape.
Flavor & Vapor Production
Reviewers agree both devices deliver clean, punchy flavor thanks to PRO-FOCS 4.0 and ITO atomization. The G4’s adjustable power and airflow let you dial in your draw, while the Mini still surprises with strong MTL and RDTL hits for its size.
Pricing & Value
G4 Mini Pod Kit – $12.98
A cheap option that still performs well. The G4 Mini has a long-lasting battery and great flavor, so it’s an easy pick for everyday vaping.
G4 Pod System – $23.98
If you like more control, go for the G4 Pod System. It adds customization, a display screen, and extra modes — worth the bit higher price.
Use and Safety Tips
Prime each new pod with a few drops of e-liquid before vaping. Charge only on a flat surface using the included USB-C cable. Avoid leaving devices unattended while charging. Always store your Uwell Caliburn in a cool, dry place away from direct sunlight.
Which One Should You Choose?
- Choose the G4 Mini if you’re new to vaping or want a lightweight, foolproof device for everyday carry.
- Opt for the Caliburn G4 if you value a color screen, adjustable power modes, and separate locks for screen and firing button.
Both models uphold Uwell’s reputation for durability, leak resistance, and pure flavor. Your choice simply depends on whether you prefer ultimate simplicity or extra customization.
