Caliburn pods come in five families, and the family, not the model number, decides the fit. Every G3, G4 and G5 model, plus the Caliburn Air, takes G Pod Platform (GPP) cartridges, so G3 pods fit them all. The A3, A3S, AK3, AZ3 and AZ3 Grace share A3-family pods, while the A2, A2S and AK2 share the A2 pod. The G2, GK2, Tenet and GZ2 run on replaceable Caliburn G and G2 coils, and the original Caliburn and KOKO have pods of their own. The chart below covers 41 Caliburn devices, checked against Uwell’s own pages and manuals.
AT A GLANCE
✓G3 pods fit G4 and G5 Uwell says GPP cartridges are fully compatible with the Caliburn G5, G4 and G3 series. The Air takes them too.
✓A3 pods travel Uwell groups A3, A3S and AZ3 (Grace) pods for the A3, A3S, AK3, AZ3 and AZ3 Grace.
✓A2 pods stay in A2 The 0.9Ω A2 pod fits the A2, A2S and AK2. Uwell doesn't list A2 and A3 pods across families.
✓G coils, not G3 Caliburn G and G2 coils fit the G2, GK2, Tenet, GZ2, X and Explorer. G3 and later pods have the coil built in.
How Caliburn pod compatibility works
Uwell has made more than 40 Caliburn devices, and they don’t all share a pod. What decides the fit is the pod family the device was built around. Grouping the pods by the devices Uwell lists them for, we count five families:
1.G Pod Platform (GPP): G3, GPP and GPP Alpha cartridges for every G3, G4 and G5 model and the Caliburn Air. The coil is built into the cartridge, so you replace the whole pod.
2.Caliburn G coil platform: refillable pods with replaceable Caliburn G (0.8Ω, 1.0Ω) and G2 (1.2Ω) coils, for the G, G2, GK2, KOKO Prime, Tenet, GZ2, X, Explorer and Ironfist L.
3.A3 pods: A3, A3S and AZ3 (Grace) pods for the A3, A3S, AK3, AZ3 and AZ3 Grace.
4.A2 pods: the 0.9Ω A2 pod for the A2, A2S and AK2.
5.Original pods: the 1.4Ω Caliburn pod and the 1.2Ω KOKO pod.
One thing to know before you read the chart: none of the Uwell pages we checked says
“not compatible.” Uwell lists which pods and coils each device takes. When a pod isn’t on a device’s list, we don’t recommend it for that device.
The Uwell Caliburn pod compatibility chart
Each row shows the pods and coils Uwell lists for that device on an official Uwell source: the device’s product page, Uwell’s G Pod Platform page, another Caliburn page’s compatibility section, or the user manual.
Uwell Caliburn pod and coil compatibility chart: 41 devices
Not in the chart: Caliburn-branded prefilled and disposable products, which don’t take refillable pods. The G3 ECO has no page of its own: its row comes from the G3 ECO specifications on Uwell’s G3 page and from the GPP page.
G3, G4, G5 and Air: the G Pod Platform
Yes, G3 pods fit the G3 Pro, G3 Lite, GK3, every G4 and every G5. Uwell calls this the G Pod Platform and says GPP cartridges are “fully compatible with the CALIBURN G5·G4·G3 series devices.” Its GPP page names 16 devices. The G5 and Air pages add themselves with “All cartridges in G Pod Platform (GPP) are compatible with CALIBURN GPP series devices,” and the G5 KOKO page says they “are compatible with CALIBURN G5 & G4 & G3 series devices.” The G4 pages also say the upgraded GPP cartridges “are also compatible with the CALIBURN G3 series devices,” so the fit goes both ways.
The G3 and GPP cartridges have the coil built in. Uwell calls them “Integrated Coil Cartridges,” so there is no separate coil to buy and you replace the whole pod. We carry them as Uwell Caliburn G3 replacement pods.
Picking a resistance: Uwell’s G5 KOKO manual gives a power range for each one: 0.4Ω at 19W to 35W, 0.6Ω at 13W to 25W, 0.9Ω at 9W to 15W and 1.2Ω at 6W to 11W. The G3, G3 ECO, G3 Lite, G3 Lite KOKO, GK3, GK3 Tenet and Air top out at 25W, while the G3 Pro, G3 Pro KOKO, G4, G4 mini, G4 Pro KOKO, G4 Classic, G5 KOKO and G5 Lite models go up to 35W. Check your device’s maximum before you pick the 0.4Ω pod.
Caliburn G and G2 coils: which devices take them
Before the G3, most Caliburns used a refillable pod with a coil you press in and swap. Uwell lists three coils for this platform, and lists them across far more devices than any one pod:
Caliburn G and G2 coils and the devices Uwell lists them for
Do Caliburn G coils fit the G2? Yes. Uwell’s G2 manual lists a 0.8Ω Caliburn G coil as the spare in the G2 kit, next to the pre-installed 1.2Ω G2 coil. Do they fit the G3? No coil fits the G3: its cartridges have the coil built in, and Uwell doesn’t list G or G2 coils for any G3, G4 or G5 model.
The pods are a different story. The coils are shared, but Uwell groups the pods more narrowly:
G2, GK2, GK2 (Vision), Tenet, Tenet KOKO, GZ2 and GZ2 Cyber: Uwell’s GZ2 page puts all six under a “Wide compatibility” heading, “the smarter way to use pod,” and the GZ2 Cyber page adds itself.
Caliburn G and KOKO Prime: each has its own 2mL top-fill pod for G coils. Uwell doesn’t place them in the GZ2 group or say they swap with each other.
Caliburn X: its own 3mL pod. Uwell’s manual calls it the “CALIBURN X Empty Cartridge.” Buy Caliburn X pods with coils fitted, or Caliburn X empty pods for your own coils.
Caliburn Explorer: a side-fill Explorer empty cartridge with 4mL of capacity, 2mL per side, and a coil on each side. Uwell ships it with a 0.8Ω G coil and a 1.2Ω G2 coil. Replacements are Caliburn Explorer pods.
Caliburn & Ironfist L: a 2.5mL pod that takes all three coils. Uwell doesn’t list it for any other device.
A2 and A3 pods: two separate families
Uwell lists the A-series pods by resistance with no separate coil, so you replace the whole pod. It also keeps the A2 and A3 families apart. No Uwell page lists an A2 pod for an A3-family device or the reverse.
A2 and A3 family pods
How to read the A3 group: the A3S page says it “is compatible with A3’s pod,” the AK3’s spec lists the 1.0Ω A3 pod, and the AZ3 ships with A3 pods in 0.8Ω and 1.0Ω. Uwell’s AZ3 Grace page then shows the A3, A3S and AZ3 (Grace) pods together under “Wide compatibility” with all five devices: A3, A3S, AK3, AZ3 and AZ3 Grace.
How to read the A2 group: the A2S page says the device “is compatible with the 0.9 Ω CALIBURN A2 refillable pod,” and the AK2 page says “Caliburn A2 & Caliburn AK2 can share one pod cartridge.” The A2S ships with its own 1.2Ω side-refill pod, which Uwell lists only for the A2S.
Original Caliburn, KOKO and KOKO Prime pods
The first Caliburns use pods you won’t find on any newer model.
Caliburn (original): Uwell’s manual gives the pod a resistance of 1.4Ω (plus or minus 0.1Ω) and an 11W maximum. Replacements are Uwell Caliburn 1.4Ω pods.
Caliburn KOKO: ships with a 1.2Ω KOKO pod, and its manual adds “Compatible with 1.4 Ω CALIBURN pod which needs to be purchased separately.” So a KOKO takes both KOKO pods and original Caliburn pods. Uwell doesn’t say the KOKO pod fits the original Caliburn.
KOKO Prime: despite the name, it isn’t built around KOKO pods. Its 2mL top-fill pod takes Caliburn G coils, with a 1.0Ω coil pre-installed and an 0.8Ω UN2 Meshed-H coil sold separately. The KOKO Prime (Vision) lists the same coils and adds the 1.2Ω G2 coil.
Which pods fit the KOKO Prime? Uwell lists its own pod with Caliburn G coils. Uwell doesn’t name a separate replacement pod for it, and doesn’t say whether Caliburn G or G2 pods fit it.
What Uwell's pages don't settle
We built this chart from Uwell’s own pages and manuals only, and a few of them disagree or leave gaps. Here’s where, and what we did about it:
G pods, KOKO Prime pods and G2-group pods. All three take the same coils, but Uwell never says the pods swap with each other. The chart lists only the pods Uwell names for each device.
G2 coils in the Caliburn G and KOKO Prime. Uwell lists the 1.2Ω G2 coil for the KOKO Prime (Vision) but not for the Caliburn G or the standard KOKO Prime, and the Caliburn G page lists only the 0.8Ω coil.
A3 pod resistances. The A3 and AK3 pages list a 1.0Ω A3 pod; the AZ3 and AZ3 Grace pages also list an 0.8Ω A3 pod.
GPP Alpha cartridges. Uwell calls them GPP cartridges and says all GPP cartridges fit GPP devices, but the GPP page’s device list doesn’t yet name the G5, G5 KOKO or Air, and the only Alpha resistance Uwell lists is the 0.6Ω version in the G5 and Air kits.
KOKO Prime (Vision) output: the page title says 15W and the spec list says 18W.
G3 ECO: it has no product page of its own. Uwell lists it on the GPP page and gives its specs in a G3 ECO block on the G3 page.
If you’re not sure a pod fits your device, stick with one Uwell lists for it in the chart. If the pod doesn’t seat firmly, don’t force it.
Frequently asked questions
Which pods are compatible with the Caliburn G3?
Any G Pod Platform (GPP) cartridge. Uwell says GPP cartridges are fully compatible with the Caliburn G3, G4 and G5 series, in 0.4Ω, 0.6Ω, 0.9Ω and 1.2Ω, side refill or top refill. That means Caliburn G3 pods also fit the G3 Pro, G3 Lite, GK3, G4 and G5 models. Older A-series and G2-style pods aren’t listed for the G3.
Do Caliburn A3 pods fit the A3S, AK3 and A2?
They fit the A3S, AK3, AZ3 and AZ3 Grace: Uwell groups the A3, A3S and AZ3 (Grace) pods across all five devices. Uwell doesn’t list A3 pods for the A2, A2S or AK2, which use the A2 pod. Shop Caliburn A3 pods or A3S pods.
Do Caliburn A2 pods fit the A2S and AK2?
Yes. Uwell says the A2S “is compatible with the 0.9 Ω CALIBURN A2 refillable pod” and that the A2 and AK2 “can share one pod cartridge.” The A2S’s own 1.2Ω side-refill pod is listed for the A2S only. See Caliburn A2 pods.
Do Caliburn G coils fit the G2 and G3?
They fit the G2: Uwell puts an 0.8Ω Caliburn G coil in the G2 kit as the spare. They don’t fit the G3, whose cartridges have the coil built in. The 1.2Ω G2 coil fits the G2, GK2, Tenet, GZ2, X and Explorer, per Uwell.
Which pods fit the Caliburn KOKO and KOKO Prime?
The original KOKO takes its 1.2Ω KOKO pod and, per its manual, the 1.4Ω Caliburn pod. The KOKO Prime uses its own pod with replaceable Caliburn G coils (1.0Ω and 0.8Ω). Uwell doesn’t say other pods fit the KOKO Prime.
What pods does the Caliburn X take?
Its own 3mL pod, which Uwell calls the Caliburn X Empty Cartridge, with Caliburn G or G2 coils (0.8Ω, 1.0Ω or 1.2Ω).
