OXVA XLIM Pro 3 vs Uwell Caliburn G4 — Which Pod Kit Should You Buy? (UK 2026)
The Uwell Caliburn G4 is Uwell’s premium pod kit for 2026 — a step up from the widely loved G3 with a larger battery, HD colour display, and 35W output. The OXVA XLIM Pro 3 sits in the same premium budget tier at a similar price. This comparison settles which one to buy.
Short answer: The XLIM Pro 3 wins for MTL flavour, pod capacity, and charging speed. The Caliburn G4 wins for maximum wattage output (35W vs 30W) and for existing Caliburn users who know the pod ecosystem.

Pod Ecosystem — The Hidden Differentiator
The Caliburn G4 uses Uwell’s GPP pod platform — which means you get the same pods as the Caliburn G3. Only two resistances: 0.4Ω for DTL and 0.9Ω for MTL. The XLIM range gives you four resistances (0.4, 0.6, 0.8, 1.2Ω) plus three pod types (V3, EZ, Stainless Steel). More pod choice = more control over your vaping experience.
Flavour for MTL Vapers
For mouth-to-lung vapers specifically, the XLIM Pro 3 with a 0.8Ω or 1.2Ω pod delivers tighter, more flavourful hits. The Caliburn G4’s 0.9Ω MTL pod is good, but the OXVA Pulse System means flavour stays consistent even when the battery drops below 30%. This makes a real-world difference for full-day vapers.
Pod Capacity
The XLIM Pro 3’s 4ml pod holds twice as much e-liquid as the Caliburn G4’s 2ml pod. For heavy vapers this halves the number of refills needed per day — less mess, more convenience.
