Uwell Caliburn Pod Compatibility Chart: Which Pods and Coils Fit

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.

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. Device names link to the kit on Black Note where we carry it. Output is Uwell’s spec.

Where to buy each family: Caliburn G3 pods (all GPP devices), Caliburn G coils, Caliburn G2 coils, Caliburn G pods, Caliburn G2 pods, Caliburn X pods, Caliburn X empty pods, Caliburn Explorer pods, Caliburn A2 pods, Caliburn A3 pods, Caliburn A3S pods, original Caliburn 1.4Ω pods and Caliburn KOKO pods.

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.

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.

For the devices themselves, see our G3 review, G3 Pro review and G3 Pro KOKO review.

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:

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. We carry Caliburn G2 pods for this group.
• 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. We carry Caliburn G pods for the G.
• 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.

Our reviews of the Caliburn G, G2, GZ2, Tenet, Caliburn X and Explorer cover each device in more depth.

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.

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.

More on the devices in our A3 review, A3S review, AK3 review, A2S review and AK2 review.

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. Our KOKO Prime review covers the device itself.

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.

Resistance tells you how a pod draws. As a general rule (our guidance, not Uwell’s), higher-resistance MTL pods and coils, such as the 1.0Ω, 1.2Ω and 1.4Ω, run at low power with a tight, mouth-to-lung draw that suits Black Note salt nicotine and Black Note 50/50 tobacco e-liquids. Lower-resistance pods and coils, such as the 0.8Ω, 0.6Ω and 0.4Ω, run at higher power with a looser draw and pair with thicker 70VG/30PG e-liquid. The 0.9Ω pods sit between the two, so choose by the draw you like.

For adults 21 and older only. Nicotine is an addictive chemical. This guide is educational and does not make medical or stopping-smoking claims. Follow the manufacturer’s instructions for your device and pods. Compatibility, power and capacity details were checked against Uwell’s official product pages, G Pod Platform page, user manuals and kit images on October 15, 2026. Where Uwell’s sources disagree, we say so above. Black Note did not bench-test the pods for this guide.
