Caliburn G3 Pods vs GPP Pods: Which Fit Your Kit and What's the Difference?

We get asked this constantly. "Do GPP pods fit my G3?" "Are G3 pods the same as GPP?" "Which resistance do I need?" Uwell hasn't made it obvious, so I'll clear it up.

There are Caliburn G3 pods and GPP pods. Both come in four resistances. Both have top-fill and side-fill versions. They look nearly identical. Confusing? Yeah. But the actual differences are small, and both work with the same kits.

What Are G3 Pods?

These launched with the original Caliburn G3 back in 2023. Four resistances: 0.4Ω, 0.6Ω, 0.9Ω, and 1.2Ω. Built-in mesh coils in every one, so when a pod's finished you bin it and grab a fresh one.

The 0.4Ω and 0.6Ω are top-fill - pull the mouthpiece off to refill. The 0.9Ω and 1.2Ω are side-fill with a rubber bung. All hold 2ml under UK TPD rules.

G3 pods fit every G3 series kit and every G4 series kit too.

What Are GPP Pods?

GPP stands for G Pod Platform. Uwell launched it alongside the Caliburn G4 as a universal pod system - one pod type that works across current kits and whatever comes next.

Same four resistances as G3 pods. Same mesh coil construction. They look almost identical from the outside. The upgrades are internal: PRO-FOCS 4.0 flavour tech (up from 3.0 on G3 pods) and a slightly tweaked version of the U² anti-leak construction.

Like G3 pods, GPP pods fit all G3 and G4 series kits.

G3 Pods vs GPP Pods: What's Actually Different?

Not much, honestly. I'll lay it out.

The jump from PRO-FOCS 3.0 to 4.0 is subtle. I've used both back to back and the flavour difference is marginal at best. If you're buying fresh pods today, go GPP - it's the newer line and where Uwell is putting its development. But if you've got G3 pods that work well, absolutely no reason to switch.

Which Pods Fit Which Kit?

Every G3 kit takes both pod types. One thing to watch: the 0.4Ω pod wants 20-25W to run properly. Kits that max out at 25W will fire it, but only just. The 35W kits give it room to breathe.

The G3 Lite doesn't support the 0.4Ω well at all - stick with 0.6Ω and above on that kit. The G3 Pro and G3 Pro KOKO handle everything including the 0.4Ω without issue.

Own a G4 kit? Same story. All G3 and GPP pods fit across the G4 range too.

Which Resistance Should I Pick?

Same options whether you buy G3 or GPP. The coil construction is identical across both lines.

1.2Ω (8-12W) - Tightest draw, closest to a cigarette. Strong throat hit, low vapour. Pair with 20mg nic salts. The go-to for heavy smokers making the switch.

0.9Ω (12-16W) - Comes included with most G3 kits for a reason. Slightly more open than the 1.2Ω but still firmly MTL. Works brilliantly with 10mg or 20mg salts. If you don't know what to pick, pick this.

0.6Ω (16-20W) - Restricted lung draw. Warmer, more vapour, sits between MTL and a proper lung hit. Better with 50/50 freebase or lower strength salts.

0.4Ω (20-25W) - Loose draw, most vapour. Only runs right on 35W kits. Best with freebase e-liquids.

Coming off disposables and not sure? Start with the 0.9Ω. Closest thing to what you're used to.

Do I Need to Switch from G3 to GPP?

No. If your G3 pods are doing the job, keep buying them. Both types fit the same kits, come in the same resistances, and perform near identically. GPP is where Uwell is heading with future releases, so it'll likely become the main option over time. But right now either works.

New G4 kits may ship with GPP pods in the box rather than G3. Doesn't matter - they're cross-compatible. Pick up whichever type you prefer from our Caliburn pods collection.

What About Prefilled Caliburn G3 Pods?

Uwell did release prefilled G3 pods through the GPP, preloaded with e-liquid in a range of flavours. These are MTL only at a single resistance. Availability varies by region and in the UK the refillable pods are what most retailers stock, us included. Worth checking back on as availability shifts.
