Uwell

Uwell is the brand behind the Caliburn pod kit family, one of the most recognised MTL setups on the UK market, and now the higher-puff Viscore 8000 line. We carry the full current Caliburn generation, from the compact G3 Pro to the bigger-battery G5, along with genuine Ironfist L and GPP ALPHA replacement pods to keep them running. Everything here is the real Uwell hardware, ready to add to your basket today.

About Uwell

Uwell built its reputation on the Caliburn pod kit family, the compact MTL/RDL kits that popularised refillable pods with adjustable wattage in a shirt-pocket size. That's still the backbone of what we stock: refillable Caliburn kits running from a 1000 mAh battery up to a 2000 mAh one, all built around 2ml pods you top up with your own e-liquid. Alongside them sits the Viscore 8000, a fixed power kit built around bigger prefilled pods for anyone who'd rather not fill up at all.

You'll hear the Uwell name alongside the Valyrian range too, though what we stock here is the Caliburn and Viscore side of the catalogue, the kits, the KOKO colourways and the spare pods that keep them going. Running low on a pod? The Caliburn range covers the Ironfist L and GPP ALPHA pods that fit most of the newer kits.

A quick shape of what's here:

  • Caliburn G3 Pro / G3 Pro KOKO: 1000 to 1250 mAh batteries, the smallest of the line.
  • Caliburn G4 / G4 Mini / G4 Classic: 1100 to 1400 mAh, the everyday MTL workhorses.
  • Caliburn G4 Pro / G4 Pro KOKO: bigger 1800 to 2000 mAh batteries, with a screen on the KOKO edition.
  • Caliburn G5 / G5 Lite / G5 Lite SE / G5 KOKO: the newest shells, 1200 to 1600 mAh.
  • Viscore 8000: fixed power, prefilled pods good for 8,000 puffs, no filling or wattage dial needed.

How to choose your Uwell

Battery life vs pocket size

If you vape a lot and don't want to top up charge mid-afternoon, go for the Caliburn G4 Pro or G4 Pro KOKO: their 1800 to 2000 mAh batteries are the biggest in the range, and the KOKO edition adds a screen so you can see where the charge is. If you'd rather have something that disappears into a pocket, the Caliburn G3 Pro's 1000 mAh cell keeps the kit small.

Refillable or prefilled

Every Caliburn kit here is refillable: you fill a 2ml pod, or the XL-capacity GPP ALPHA pod, with your own e-liquid and swap it when the coil inside wears out. If you'd rather skip the bottle altogether, the Viscore 8000 runs on prefilled pods instead, so you just click one in and vape.

Which Caliburn generation

  • New to Uwell or want the current shape: pick a Caliburn G5 kit. The Lite SE and Lite are simpler versions of the same shell, and the standard G5 has the bigger 1600 mAh battery.
  • Want something proven and widely used: the Caliburn G4 family (Classic, Mini, Pro) covers most battery sizes and is the one most vapers already know how to use.
  • Fancy a leather-effect finish: the KOKO editions (G3 Pro KOKO, G4 Pro KOKO, G5 KOKO) swap the standard shell for the KOKO design in finishes like Golden Leopard and Brown Leather.

Coils and pods

Running a Caliburn dry or getting a burnt taste means the coil built into the pod needs replacing, not the whole kit. Grab a pack of refillable pods sized for your device, GPP ALPHA pods for that system or Ironfist L pods if your kit takes that shape, and you're back to full flavour in seconds. In day to day use, most people find a Caliburn pod lasts a good couple of weeks before it's worth swapping, longer if you keep the wattage moderate.

Starter kit or pods only

If you're picking your first Uwell, start with a full kit from the pod kits range, battery, pod and cable included. If you already own the device and just need pods, head straight to vape pods instead, or to prefilled pods if you're running the Viscore 8000.

Uwell FAQs

Which Uwell Caliburn should I buy?

If size matters most, take the Caliburn G3 Pro. If you want the biggest battery, go for the G4 Pro or G4 Pro KOKO. Want the newest shell with a proven battery size, pick a Caliburn G5. All are refillable, so it mostly comes down to battery size and finish.

Are Uwell Caliburn pods refillable?

Yes. Every Caliburn kit we stock uses refillable pods, either the standard 2ml pod or the larger GPP ALPHA pod, so you top up with your own e-liquid rather than replacing the whole pod each time. Only the Viscore 8000 uses prefilled pods instead.

What is the Uwell Viscore 8000?

It's a fixed power kit built around a prefilled pod rated for around 8,000 puffs, with a pod capacity of 2ml plus 10ml. There's no wattage dial to set and no bottle to carry, you click a prefilled pod in and you're ready to go.

How do I get replacement coils for my Uwell?

On Caliburn kits the coil sits inside the pod itself, so you replace the pod rather than a separate coil. Choose GPP ALPHA pods or Ironfist L pods to match your device, both refillable, and swap in a fresh one whenever flavour starts to fade.

Does Uwell make the Valyrian?

Uwell's line-up does include the Valyrian range alongside Caliburn, but on this page we stock the Caliburn pod kit family and the Viscore 8000. If you're after Valyrian specifically, it isn't part of the range we currently carry here.

What's the difference between the KOKO editions and the standard Caliburn kits?

The KOKO editions (G3 Pro KOKO, G4 Pro KOKO, G5 KOKO) use the same MTL/RDL pod system and adjustable wattage as their standard counterparts, just in a different shell and finish, with colourways like Golden Leopard and Brown Leather.
