Uwell Caliburn G3 Pod Kit

Uwell Caliburn G3 Refillable Pod Kit

The Uwell Caliburn G3 is a compact aluminium alloy pod kit built for both mouth-to-lung (MTL) and restricted-direct-to-lung (RDTL) vaping. It comes with a 900mAh built-in battery, variable wattage from 5 to 25W, and an OLED display screen that shows wattage, resistance, battery level, and puff count at a glance. The G3 uses Uwell's side-fill G3 pod platform, with three coil options (0.6ohm, 0.9ohm, and 1.2ohm) to cover different vaping preferences.

Three firing modes give you full control: button only, auto-draw only, or both simultaneously. The kit includes two pods to get you started and suits both beginners stepping up from disposables and experienced vapers wanting a dependable, feature-rich daily device.

900mAh Built-In Battery

The Caliburn G3 carries a 900mAh built-in battery, which is a 20% increase over its predecessor. Most vapers will get through a full day on a single charge with moderate use. The battery level is shown clearly on the OLED screen so you always know exactly how much charge remains, rather than relying on a coloured LED. When it does need charging, the USB Type-C port supports 2A fast charging for a quick turnaround.

5-25W Variable Wattage Output

Unlike fixed-output pod kits, the Caliburn G3 lets you adjust wattage in steps between 5W and 25W to suit your pod and preference. Lower wattages give a cooler, tighter draw with more flavour subtlety, while higher settings produce a warmer hit with more vapour. Wattage is changed with three quick clicks of the fire button and displayed immediately on the OLED screen. The 0.6ohm pod runs best at higher wattages for an open RDTL draw, while the 0.9ohm and 1.2ohm options are better suited to lower settings for a tighter MTL vape.

OLED Display Screen

The G3's OLED screen gives a clear read of the current wattage, coil resistance, battery level, and puff count. This puts the Caliburn G3 in a different category to simpler pod kits that rely only on LED indicators. Seeing the resistance reading is particularly useful when switching between pods, as it confirms the coil has been detected correctly. The puff counter also helps you keep track of your usage. Safety alerts including low battery, short circuit, and atomiser errors are shown on the screen too, so you are not left guessing if something is wrong.

Three Firing Modes and Button Lock

The G3 offers three activation options: fire button only, auto-draw only, or a combined mode that allows both simultaneously. To cycle between modes, click the fire button three times. Auto-draw mode is the most familiar option for those switching from disposable vapes, while button mode gives more precise control over when vapour is produced. Pressing the button five times locks the device, preventing accidental firing in a pocket or bag. The current mode and lock status are reflected on the OLED display, so there is no guesswork involved.

To unlock the Caliburn G3, press the fire button five times in quick succession. The screen will confirm that the device is unlocked and ready to use.

Compatible with Caliburn G3 and GPP Pods

The Caliburn G3 accepts pods from both the Caliburn G3 series and the Caliburn GPP series. The kit includes one 0.6Ω and one 0.9Ω G3 pod as standard. Both series use integrated coils, so you replace the whole pod rather than swapping coils separately.

Caliburn G3 pods (included in box):

• 0.6Ω: RDTL, side-fill
• 0.9Ω: MTL/RDTL, side-fill
• 1.2Ω: MTL, side-fill, tightest draw

Caliburn GPP pods:

• 0.4Ω: RDTL, 35W
• 0.6Ω: RDTL, 25W
• 0.9Ω: MTL, 15W
• 1.2Ω: MTL, 13W

2ml Side-Fill Refillable Pod

Each Caliburn G3 pod holds 2ml of e-liquid in line with UK TPD regulations. Refilling is done through a side port sealed with a red silicone plug. Push the nib of your e-liquid bottle into the port to fill, then release to let the silicone seal close again. You do not need to remove the pod from the device to refill. The side-fill design, combined with Uwell's ultrasonic welding construction, keeps the pod sealed tightly and greatly reduces the chance of leaking. After filling, leave the pod to stand upright for a few minutes before vaping to allow the coil to saturate properly.

Dual Airflow via Pod Rotation

The Caliburn G3 uses the same pod rotation system as other devices in the Caliburn G series. Rotating the pod within the device aligns different-sized airflow inlets on the base of the pod with the device's air channel. Pointing the smaller inlet towards the device tightens the draw for a closer MTL feel; rotating the pod so the larger inlet faces the device opens it up for an RDTL style. No sliders or switches are needed, which keeps the device clean and reduces wear points.

E-Liquid Viewing Window

The Caliburn G3 pod has a clear PCTG body with a wide viewing window on both sides, allowing you to check the e-liquid level without removing the pod. The dual-window design is an improvement on earlier models and means you can see the level from whichever angle the device is facing. Keeping an eye on the level helps you top up before the coil runs dry, which preserves both coil life and flavour quality.

Pro-FOCS Flavour Technology with Ultrasonic-Welded Pods

Uwell's Pro-FOCS (Flavour Optimisation Coil System) technology is built into every Caliburn G3 pod to maximise how completely the coil extracts flavour from your e-liquid. Alongside this, the pod construction uses ultrasonic welding to create an air-tight seal throughout the pod body, which addresses the leaking issues that affected earlier Caliburn generations. The welded design also includes a small anti-spitback channel between the coil and the mouthpiece, which prevents hot e-liquid droplets from reaching the mouth during use.

USB Type-C Charging with 2A Fast Charge

The Caliburn G3 charges via a USB Type-C port and supports 2A fast charging, so a flat battery can be topped up quickly. A Type-C cable is included in the box, which is a practical touch not found on all pod kits in this range. The device can be used while plugged in, which means you do not need to pause vaping during a charge. The OLED screen shows the charging status and remaining battery level while the device is connected.
