Uwell is a Shenzhen-based vape hardware brand established in 2015, best known in the UK for the Caliburn pod-kit family – one of the most-recommended entry and mid-range MTL pod systems in Europe. The Uwell range at Local Supplies covers the current Caliburn kit line-up (G3 Pro, G4, G4 Classic, G4 Pro KOKO) plus the matching replacement pods for the A2, GPP and older Caliburn generations. Prices run from £9.49 for a 4-pack of replacement pods up to £22.99 for the flagship G4 Classic kit.

What separates Uwell from a lot of the UK vape hardware market is engineering quality. The Caliburn brand has a solid reputation for pod integrity (they don't leak the way cheaper pod kits often do), battery life that matches the advertised numbers, and coil consistency – a fresh pod tastes the way a Caliburn is supposed to taste, and the last few draws before you change it still taste passably good. That's why Caliburns are one of the most common first refillable kits UK vape shops recommend to people moving off single-use bar vapes.

The Uwell Caliburn Range – A Quick Map

Uwell's naming can be confusing at first – there are Caliburn G-series, A-series, KOKO variants, Mini variants, Pro variants, and pod names that don't match the kit names. Here's the plain version:

• Caliburn G-series – the main lineage. G, G2, G3, G4, and their Pro/Mini variants. Rectangular device shape, higher battery capacity, more advanced draw controls on the Pro versions.
• Caliburn KOKO series – squarer, more pocket-friendly form factor. KOKO Prime, KOKO variants, G4 Pro KOKO. Same pod system as the G-series equivalent, different device shape.
• Caliburn A-series – simpler, cheaper starter kits. A2, A3, A3S. Draw-activated only, no buttons, different pod fitting to the G-series.
• Caliburn GPP pods – the newer, wider-coil pod format designed for the G3 and G4 Pro variants. Not backward-compatible with older G-series kits.

The single most important thing to check before buying a replacement pod: match the pod name to the exact kit you own. Cross-compatibility is limited even within the Caliburn family – more on that further down.

Uwell Caliburn Pod Compatibility – Which Pods Fit Which Kits?

The single most-asked question about Uwell hardware, and the source of the most wasted orders. A quick reference:

Two rules that solve 90% of the confusion:

1. The G3 Pro, G4, G4 Classic and G4 Pro KOKO all use the same Caliburn GPP pods. If you own any of those four kits, GPP pods are what you need.
2. The A-series (A2, A3, A3S) uses a completely different pod system. A2 pods do not fit A3S kits, and neither fits any G-series or KOKO kit.

Uwell vs Other UK Pod Kit Brands

Uwell sits in the same competitive tier as Vaporesso and Aspire, priced slightly higher than the cheapest Aspire options but with a reputation for slightly better pod integrity and coil consistency. If you specifically want a Caliburn (many long-term vapers recommend Uwell over the alternatives), no other brand really replicates the Caliburn draw feel. If you just want a solid refillable pod kit at the lowest price, the Aspire Gotek X starts at £8.49 and is a genuine competitor.

How to Get the Most From a Uwell Caliburn

Practical setup notes that most product pages skip:

Prime the pod before first use

Every fresh Uwell pod needs 5–10 minutes of soak time after filling and before your first puff. This lets the e-liquid saturate the wick around the coil. Vape a dry pod and you'll get an immediate burnt taste that the pod usually doesn't recover from. This applies to GPP pods, A2 pods, and every other Uwell pod format.

Match the coil resistance to your vape style

Lower resistance (0.4Ω, 0.6Ω) = warmer draw, more vapour, better for restricted direct-lung inhale. Higher resistance (0.9Ω, 1.2Ω) = cooler draw, tighter mouth-to-lung inhale, closer to how a cigarette feels. Most bar-vape switchers prefer the 0.9Ω or 1.2Ω XL pods; anyone stepping up from a Caliburn to bigger clouds usually drops to 0.4Ω.

Refill before it runs dry

Empty pods with a still-active coil dry-burn the wick just like unprimed ones. If you're seeing the e-liquid level get low, refill it before the last few drops. Trying to squeeze out every last puff kills pods.
