G3, G4 and G5 devices use cartridges with integrated coils rather than separate replacement coils. Check the exact compatible cartridge, capacity, fill format and marked band before ordering.

Not sure it is the right one? Message us on WhatsApp with a photo of the pod or cartridge you are replacing rather than of the device, and we will tell you which one it is. The resistance and the capacity are usually printed on the cartridge body or stamped into its base: that marking identifies the part far more reliably than the name of the device it came out of.
One cartridge, seventeen devices, no coil to buy
GPP is UWELL’s G Pod Platform, using cartridges with integrated mesh coils. Match the exact cartridge capacity, resistance and supported device before ordering.
The GPP cartridge has an integrated coil, so the whole cartridge is replaced when replacement is indicated. A flavour change alone does not establish that it is worn: check liquid supply, charge, settings, seating and condition according to the exact instructions.
Reading a table with two variables
The listed GPP options span different draws, with 0.4 and 0.6 ohm offered for a more open option and 0.9 and 1.2 ohm for MTL use. Airflow, exact cartridge design and supported device settings matter alongside resistance; follow their instructions.
Capacity and fill method are the second axis, and they are not independent. Three millilitres comes in both side and top refill. Two and a half millilitres is side refill only. Two millilitres is top refill only. So choosing a capacity often chooses your fill method for you.
The stocked 3ml GPP cartridges serve the compatible G4 and G5 devices listed here. For an older G3 or GK3, match the exact device and cartridge size before ordering; the name of the platform alone is not a size specification.
Four of them are in the Vapesoko range
The G4, G4 Pro, G5 Koko and G5 Lite SE all run this cartridge, which makes GPP the busiest consumable on the UWELL side of this catalogue. For an older Caliburn G3 or GK3, select the GPP cartridge capacity and resistance supported by that exact model.
G4 and G5 coils are integrated into GPP cartridges
The G3, G4 and G5 devices discussed here use cartridges with integrated coils. Replace the supported complete cartridge, rather than buying a separate coil.
Choose a GPP cartridge supported by the exact device, checking resistance, capacity, fill format and marked operating band. The stocked pack is three 3ml side-fill cartridges; matching resistance alone is not the complete compatibility check.
The older UWELL Caliburn G2 Replacement Coils platform is the one where a separate coil exists, and it fits nothing on the list above. The UWELL Caliburn G3 Refillable Pod is the same idea as a GPP cartridge under an earlier name, while the UWELL Caliburn A3 Refillable Pod belongs to a separate line altogether.
Getting a new cartridge started
The coil is integrated, but its wick still needs liquid saturation. Fill through the correct port and wait for the exact cartridge/device first-fill duration before use. The G4 manual specifies ten minutes after first fill; do not apply a blanket five-minute wait across every supported GPP device. Use powered-off priming pulls only where the exact instructions support them, checking the state of any auto-draw device.
Power controls depend on the device. Automatic-output models select power from the fitted cartridge; adjustable models let you change it. Follow the cartridge guidance and your device manual rather than assuming that every GPP-compatible kit chooses the same output. UWELL publishes resistance-specific bands on the G5 Koko device page; older devices may have different limits.
GPP Alpha and its manufacturer lifespan benchmark
UWELL make a second cartridge on this platform called GPP Alpha, in the same four resistances at three millilitres and two, with a fill port at the top and side. It carries a manufacturer-published lifespan benchmark; other consumable families also have attributed figures.
UWELL gives the separate GPP Alpha cartridge a 50ml manufacturer benchmark, expressed as 17+ refills for 3ml or 25+ for 2ml. That claim belongs to Alpha, not to this original GPP cartridge.
GPP Alpha also has a soft-touch mouthpiece. Check the exact cartridge version when comparing these features.
Liquid ratio and concentration are separate choices
Suitable 50/50 liquid is the stocked pairing for supported pod/MTL configurations at 0.6Ω and above. Check the exact GPP cartridge and device instructions; neither pod construction nor resistance alone determines nicotine form, concentration or every compatible liquid ratio.
Choose the exact coil code and a compatible cartridge/device, then follow its marked power range and liquid guidance. Resistance alone does not prescribe nicotine concentration or guarantee nicotine delivery. Suitable 50/50 liquids are used on our stocked pod/MTL setups at 0.6Ω and above; concentration suitability remains separate, and lower-resistance DTL options require their own exact guidance. Compare individual bottles in ELFBAR ELFLIQ 10ml and ELFLIQ Salts Ice King 30ml.

When to replace a pod or coil
Use the pod and coil replacement guide to check symptoms and identify the correct part. Check liquid supply, charge, supported settings and component condition before replacing a pod or coil.
