Uwell Caliburn guide: G3, G4 and G5 compared

Three Caliburn names keep coming up when people ask us for a pod kit: G3, G4 and G5. They look alike on a shelf, they take the same cartridges, and the price gap between them is bigger than the difference in how they vaporise. Here is what actually changes from one to the next, going by the specs on each product page and what Uwell says about its own cartridges.

The Uwell Caliburn family in one table

Every kit below is a pen-style open pod kit that you fill yourself, and every one is listed in our Uwell Caliburn range alongside other open pod kits. Prices are ours today.

Caliburn G3: the compact one with the smallest battery

The G3 is where the current Caliburn cartridge family began. It has a 750mAh battery, up to 25W and a 2.5ml side-fill cartridge, plus an OLED that shows power and puff count. The cartridges come in 0.6, 0.9 and 1.2 ohm mesh, so it leans towards a tight, cigarette-style mouth-to-lung draw.

It is the one to pick if you want a small, simple device and are happy to charge it often. At 750mAh it will not last as long between charges as anything newer in this list.

Caliburn G4 and G4 Pro: the screen models

The Caliburn G4 adds a bigger 1300mAh battery, a 0.85 inch colour screen and two modes, Storm and Waves. It ships with a 0.4 ohm and a 0.9 ohm 3ml cartridge, so you can try a looser restricted lung draw and a tighter mouth-to-lung one before you commit. The 0.4 ohm cartridge runs 5 to 35W and the 0.9 ohm one 5 to 15W.

The G4 Pro steps up to an 1800mAh battery, a touchscreen with six themes and 2.5A USB-C charging, and adds a Custom mode. You get a 0.4 and a 0.6 ohm cartridge in the box. At today's prices it costs the same as the plain G4, so the Pro is the easier pick of the two.

Caliburn G5 and G5 Lite: the long-battery pair

The G5 has a 1600mAh battery that Uwell rates at up to six days, 35W, stepless side airflow and a tap sensor that switches modes with a triple tap. It comes with three 3ml cartridges: 0.4 ohm, 0.6 ohm and a longer-life GPP Alpha pod. For a first Caliburn, it comes with a full set of cartridges to try.

The G5 Lite keeps the same 1600mAh battery and 35W ceiling but drops the sensor and screen. It is draw-activated, has a four-bar LED for battery level and ships with one 0.6 ohm cartridge. If you never look at a screen anyway, it saves a few thousand rupees.

Caliburn G4 Mini: for the smallest pocket

The G4 Mini is a 24mm wide pen weighing about 46g, with an 1100mAh battery and the same 35W ceiling. No screen, no button, one 0.6 ohm cartridge. It is a light, pocket-friendly way into the current cartridge family.

Caliburn pods: which ones fit which kit

This is where people buy the wrong part. Uwell says its G Pod Platform (GPP) cartridges fit the G3, G4 and G5 series, so one cartridge style covers every kit in the table above. The coil is built into each cartridge, so changing the cartridge changes the coil.

Older Caliburns work differently. The Caliburn G and G2 take 2ml top-fill pods with a removable coil sold separately, and the Caliburn A3 uses its own 2ml pod with a built-in 1.0 ohm mesh coil. Do not mix them up: they are different parts for different devices. Browse our replacement pods and check the "fits" line on each page before ordering.

One honest limit: we do not currently list a GPP cartridge as a stand-alone product, so for G3, G4 and G5 kits the cartridges in the box are what we stock. Keep a spare in mind when you buy.

Which Caliburn should you buy?

• Longest battery for the money: the G5 Lite or the G5.
• Screen and the most modes: the G4 Pro.
• Smallest and lightest: the G4 Mini.
• Cheapest way into the GPP family: the G4 Mini or the G5 Lite, which sit close together in price.

Whichever you choose, nicotine strength is your call and e-liquid is sold separately. Uwell says its GPP cartridges handle both freebase and nic salt. If you are not sure how much to buy, start with one kit and one bottle.

Checking the box before you pay

Counterfeit pod kits exist, so check the packaging. Uwell's own verification page offers a photo-based check using the code on the packaging, or a QR scan, depending on your box. Our guide on how to check a scratch code walks through it for Uwell, Voopoo, OXVA and Vaporesso, and our authenticity page explains where our stock comes from.
