Since the original Uwell Caliburn made waves as one of the first successful pod vapes, Uwell has steadily refined its design and flavor tech. The G4 generation builds on that legacy by introducing PRO-FOCS 4.0 flavor technology for sharper taste and longer coil life. Both the G4 and G4 Mini maintain compatibility with Uwell’s GPP pod platform, so you don’t need to rebuy cartridges if you’re upgrading.

Performance & Features
Power & Output
Both models top out at 35W and auto-adjust to your pod’s resistance. The G4 adds user-selectable Storm (boost) and Waves (smooth) modes via its menu. The Mini sticks to a single, optimized power curve for simplicity.
Battery & Charging
- Caliburn G4: 1300mAh, recharges in about 30 minutes at 2A.
- G4 Mini: 1100mAh, recharges in about 58 minutes at 2A.
In practice, both last through roughly 4–5mL of e-juice before needing a refill or recharge.
Pod & Coil Compatibility
Both kits use Uwell’s GPP cartridges with built-in mesh coils. Each includes 0.4Ω (RDTL) and 0.9Ω (MTL) pods, while 0.6Ω and 1.2Ω options are sold separately. The PRO-FOCS 4.0 upgrade boosts flavor by 35% and extends pod life by 35%.
User Experience
Ease of Use
- G4: Requires a few button clicks to navigate its menu, but the quick-start guide makes it straightforward. The ability to lock both screen and fire button adds safety.
-
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.
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.
