About Caliburn Pods
Every Caliburn pod is ultrasonically welded to keep the coil chamber sealed tight. The magnetic connection clicks straight into your kit, no fiddling about, and the fill ports are wide enough for any e-liquid bottle nozzle. Uwell got the basics right and it shows in how long these refillable pods hold up.
Two ranges are available. Caliburn G3 pods come with G3 series kits but work with both G3 and G4 Series. Caliburn GPP pods (sometimes listed as G4 pods) also work with G3 and G4 series kits. Same four resistances in both, so if you own more than one Caliburn pod kit, GPP keeps things simple.
2ml capacity and 10 to 15 refills per pod means you'll get 20ml to 30ml through each one before the flavour drops off.
Caliburn G3 Replacement Pods
Caliburn G3 pods give you four resistance choices in one range. The lower resistances use top-fill designs and the MTL options use side-fill.

Top-fill pods let you refill without pulling the pod out of your kit. Side-fill pods have a rubber plug on the side that keeps things clean during refills. G3 pods work with all the Caliburn G3 & G4 series including; G3 Pro, G3 Lite, G3 Pro KOKO, G4 Pro, G4 Classic. All but the 0.4ohm will work with G3 Lite, as it doesn’t give enough power to fire it.
You get 10 to 15 refills out of each pod, so a single four-pack goes a long way.
Caliburn GPP Pods and G4 Compatibility
GPP pods work with every G3 and every G4 kit, including the G4, G4 Pro, and G4 Pro KOKO. If you've gone from a G3 to a G4, you don't need to buy two different pod types anymore.
All four resistances carry over to the GPP range. You also get Uwell's PRO-FOCS 4.0 flavour technology and the U² anti-leak design. The pods are made from PCTG so they hold up well, and you can tweak your airflow by rotating the pod in the kit.
Side-fill GPP pods come in 3-packs and top-fill in 4-packs. Top-fill gives you an extra pod for the same money, so it's the better deal if your resistance is available in both.
Uwell Pods and Refilling
Uwell refillable pods are quick to fill. It takes less than a minute either way.
How to refill your Caliburn pods:
- Pull the silicone plug (side-fill) or lift the top cap (top-fill)
- Insert your e-liquid nozzle into the fill port and fill to the line
- Let the pod sit for five minutes on your first fill so the cotton wicks properly
- After that first soak, you can refill and vape straight away
- Avoid overfilling past the line as this can cause gurgling or spit-back
50/50 VG/PG e-liquids and nic salt e-liquids work best in Caliburn pods. Thicker 70/30 VG juices can struggle to wick in the 0.9Ω and 1.2Ω MTL pods. Really sweet e-liquids will wear the coil out faster too, so you'll get closer to 10 refills than 15 with dessert or candy flavours.
G3 vs GPP Pods
Same four resistances, same vape. The only thing that changes is which kits they fit. G3 pods and GPP pods work with G3 and G4 series kits. But watch out for the 0.4ohm GPP, this won’t work in the G3 Lite as it doesn’t give out enough power to fire such a low coil. Previous Caliburn kits are not compatible either. So look for the original Caliburn pods for earlier series.
GPP pods also run Uwell's newer PRO-FOCS 4.0 technology, a step up from the G3 coil design. If you're buying your first set of pods or just want one type that fits everything, go GPP. Our guide to the best G3 series pod kits covers the full lineup if you're still choosing a kit.
Both ranges cost the same, any resistance. GPP just gives you more kit options down the line.
