About Uwell Caliburn

Uwell Caliburn is the pod vape kit line most UK vapers reach for first, and it's easy to see why the caliburn uwell name keeps coming up in searches: every model on this page uses a refillable pod, an MTL / RDL draw built for nic salts, and a battery sized to get you through a working day. Whether you're picking your first pod kit or swapping a device that's finally given up, the range below runs from a small first kit right up to a bigger, screen-equipped option built to last longer between charges.

In day to day use, most people find a Caliburn pod holds its flavour well across a fill, and swapping a spent pod for a fresh one takes seconds rather than minutes. That's a big part of why the family has stuck around across so many generations, from the original G3 through to the newer G5.

What actually changes between models here:

  • Battery size, from 1000 mAh in the smallest kit up to 2000 mAh in the biggest
  • Whether the kit gets a KOKO-style pod and, on one model, a screen
  • Pod capacity and pack size on the standalone replacement pods

If you'd rather start from scratch and browse every refillable pod kit we stock, that's the wider shelf this range sits on.

How to choose your Caliburn

All 11 Caliburn kits here share the same basics: MTL / RDL draw, adjustable wattage and a refillable pod. What separates them is battery size, a couple of screen and pod-style extras, and how compact each one is in the hand. Here's what actually differs.

Uwell caliburn g3 and g3 pro

The Caliburn G3 Pro carries a 1000 mAh battery and a 2ml pod, making it the smallest and lightest kit in the range: a solid first buy or a spare to keep in a bag. The Caliburn G3 Pro KOKO steps the battery up to 1250 mAh and pairs it with a KOKO-style pod, so it's a good pick if you liked the G3 Pro's size but want a bit more battery between charges.

Uwell caliburn g4 and g4 pro

The standard Caliburn G4 runs a 1300 mAh battery with a 2ml pod. The G4 Mini is the more pocketable option at 1100 mAh, while the G4 Classic nudges up to 1400 mAh for a longer day. If you want real battery headroom, the Caliburn G4 Pro jumps to 1800 mAh, and the G4 Pro KOKO goes further still with a 2000 mAh battery and a 2 inch screen to keep an eye on it. Anyone searching for a caliburn uwell g4 pro kit specifically for a longer battery life should start here.

The G5 line

The Caliburn G5 Lite SE and G5 Lite are essentially matched at 1200 mAh with a 2ml pod, so don't overthink the choice between those two. The Caliburn G5 steps up to 1600 mAh for noticeably more time off the charger, and the G5 KOKO matches that 1600 mAh battery with the KOKO pod style if you prefer that fit.

Stocking up on pods

Once you've settled on a kit, keep spares in stock. The Caliburn X Ironfist L Replacement Pods come in packs of 2 with a 2ml capacity, built for the Caliburn X Ironfist L. The Caliburn GPP ALPHA Pods come in packs of 4 with an XL capacity, so they're worth grabbing if you get through pods quickly. Either way, buy the pod that matches your kit rather than assuming they're interchangeable across the range.

If in doubt, here's the shape of it

  • If you want the smallest, lightest kit: take the Caliburn G3 Pro
  • If you want a similarly compact kit with a bit more battery: take the Caliburn G4 Mini or G3 Pro KOKO
  • If you want an everyday all-rounder: take the Caliburn G4 or G4 Classic
  • If you want the longest battery life and a screen to track it: take the Caliburn G4 Pro KOKO
  • If you're building a nic salt routine around it, browse our nic salts to pair with whichever pod you pick

Caliburn FAQs

Which Uwell Caliburn model should I choose?

Start with battery size. Pick the G3 Pro or G4 Mini for the smallest, lightest kit. Pick the G4 or G4 Classic as a well-rounded everyday option. Pick the G4 Pro or G4 Pro KOKO if you want the longest run time and don't mind a bigger device.

What is the Uwell Caliburn series?

It's Uwell's line of refillable pod vape kits built for an MTL / RDL draw, meaning a tighter pull that suits nic salt e-liquid. The series runs from the compact G3 through the G4 and G4 Pro kits to the newer G5 line, all sharing adjustable wattage and a top-up pod rather than a sealed cartridge.

Are Caliburn pods and coils interchangeable across models?

Not automatically. The Caliburn X Ironfist L pods and the GPP ALPHA pods are separate products with different capacities and pack sizes, built for specific devices. Match the pod to the kit you own rather than assuming one fits all, and check the product name against your device before you buy.

How long does a Caliburn pod last before I need a new one?

It depends on how often you vape and what e-liquid you run through it, so we won't put a fixed figure on it. Most people find flavour is the tell: once it starts to taste flat or the draw feels harsher than usual, that's your cue to swap in a fresh pod.

Are Caliburn kits suitable for beginners?

Yes. Every kit here is a refillable pod vape kit with a straightforward MTL / RDL draw, which is the closest style to drawing on a cigarette. Fill the pod, let the coil settle for a few minutes, and you're set. If you'd rather compare against other pod kits first, that's a good place to browse.

Do you stock the Caliburn A2 or AZ3?

Not currently. Our Caliburn shelf covers the G3, G4 and G5 families along with their KOKO editions and spare pods. If you were after an A2 or AZ3 specifically, the closest equivalents here for size and battery are the G3 Pro and G4 Mini.
