Uwell Caliburn G4 Pro Pod Vape Kit

Description - Uwell Caliburn G4 Pro Pod Vape Kit

The Uwell Caliburn G4 Pro Pod Vape Kit brings something genuinely new to the Caliburn lineup: a full 2.51" colour touchscreen with real-time control over wattage, output modes, and device settings. Built around an 1800mAh battery and adjustable output from 1 to 35W, it covers both MTL (mouth-to-lung) and RDL (restricted direct lung) vaping through the complete GPP pod range, from a tight 1.2Ω all the way to an open 0.4Ω. It works with nic salts and 50/50 e-liquids, ships with a full 1-year warranty, and every pod included is 2ml and UK TPD-compliant. Whether you're stepping up from a disposable or moving from a simpler pod kit, the G4 Pro gives you structured control without demanding any technical expertise to get started.

Introducing the Uwell Caliburn G4 Pro Pod Vape Kit

Most refillable pod kits give you a single button and a fixed power output. The Caliburn G4 Pro takes a different approach, putting a responsive touchscreen at the centre of the experience so you can actually shape how the device performs rather than just accepting its defaults.

The screen handles wattage adjustment, output mode selection, theme switching, puff tracking, and all device settings. It responds in 0.2 seconds and supports swipe navigation, making it straightforward to use even if you've never touched a device like this before. Six UI themes customise the visual layout, and eight language options are built in.

What separates the G4 Pro from the rest of the Caliburn family is Custom Mode. This lets you set three distinct wattage points across a single draw: the start, the middle, and the end. You can dial in a sharp opening hit that tapers into a smoother finish, or build gradually for a more relaxed draw throughout. It's the kind of control that experienced pod users have wanted from the Caliburn range for some time.

PRO-FOCS 4.0 flavour technology reads the resistance of whichever GPP pod you insert and automatically adjusts output to suit it. That means consistent flavour from the first pull, without needing to manually recalibrate every time you swap pods. All versions sold at Vaping 101 are fully UK TPD-compliant, with 2ml pod capacity and nicotine-containing e-liquids capped at the UK legal limit of 20mg.

Why Choose the Uwell Caliburn G4 Pro?

• Device type: Refillable pod kit with a premium aluminium body, available in 8 colourways: Desert, Stripe, Iron, Pearl, Frost, Ink, Light, and Fantasy
• Battery: 1800mAh internal battery, the largest in the Caliburn range, built for full-day MTL use
• Power range: 1-35W adjustable, with three output modes: Waves (smooth, steady output throughout the draw), Storm (front-loaded power that reduces as the draw progresses), and Custom (user-defined wattage across start, middle, and end)
• Screen: 2.51" shatter-resistant colour touchscreen with a 0.2-second response time, 6 UI themes, and 8 language options
• Airflow: Stepless slider with no fixed click stops, adjustable from tight MTL through to a more open RDL draw
• Flavour tech: PRO-FOCS 4.0 automatically reads the inserted pod's resistance and matches output accordingly for consistent taste
• Pod platform: Compatible with the full GPP (G3) range: 0.4Ω, 0.6Ω, 0.9Ω, and 1.2Ω
• Charging: USB-C, 5V/2.5A fast charging
• Ideal for: Everyday vapers upgrading from a basic pod or disposable, and switchers who want customisable output with an intuitive interface
• Compliance: 2ml pod capacity, UK TPD-compliant; UK legal nicotine limit applies (20mg maximum for nicotine-containing e-liquid)

The Custom Mode power curve is a feature that doesn't exist on the standard G4. It's the primary reason experienced pod users choose the Pro over any other model in the range.

Compatibility and Performance

• Compatible pods: All Uwell Caliburn GPP (G3) pods: 0.4Ω (RDL), 0.6Ω (light RDL), 0.9Ω (MTL), and 1.2Ω (tight MTL). Both the 0.4Ω and 0.6Ω are available in top-fill and side-fill formats
• E-liquid type: Nic salts for MTL pods (0.9Ω and 1.2Ω); 50/50 freebase for MTL and light RDL (0.4Ω and 0.6Ω). Avoid max-VG liquids as they wick too slowly in GPP pods and will cause dry hits
• Pod resistance to wattage guide:

• Output character: At higher wattage, the 0.4Ω pod produces solid vapour volume with a more open draw. The 0.9Ω and 1.2Ω at lower power deliver a concentrated, flavour-forward MTL hit that closely replicates the feel of a cigarette
• Pod capacity: 2ml per pod, UK TPD-compliant
• Charging: USB-C fast charge at 5V/2.5A keeps downtime minimal

Staying within the recommended wattage range for each pod resistance extends coil life and keeps flavour clean. There's no benefit to pushing the device toward its 35W maximum on a 1.2Ω pod - you'll burn the coil faster and the flavour will suffer.

A quick note on pod platform naming: some retailers describe the G4 Pro as compatible with "G3 pods only," which creates unnecessary confusion. GPP pods are the G3 pod series. All GPP resistances from 0.4Ω to 1.2Ω are confirmed compatible with the G4 Pro. If you already own GPP pods from another Caliburn device, they will slot straight in.

Uwell Caliburn G4 Pro Highlights

The G4 Pro is built around the idea that a pod kit can offer genuine customisation without becoming complicated. Here's what sets it apart from the rest of the range:

• 1800mAh battery - the largest internal battery in the Caliburn lineup, comfortably lasting a full day of MTL use on a single charge
• 2.51" colour touchscreen - responsive at 0.2 seconds, with swipe navigation for wattage, modes, themes, and settings
• Custom Mode power curve - set three separate wattage points across a single draw (start, middle, end) to shape each hit to your preference
• PRO-FOCS 4.0 flavour technology - auto-matches output to pod resistance for consistent, accurate taste from the first puff
• Full GPP pod compatibility - works with every GPP (G3) pod from 0.4Ω to 1.2Ω, covering both MTL and RDL in one device
• Stepless airflow - no click stops, fully adjustable from tight MTL to a more open RDL draw using a single slider
• Premium aluminium build - lightweight at 78g, available in 8 finishes across metallic, patterned, and solid colourways

Three UI themes are available straight out of the box. A further three unlock at milestone puff counts (5,000, 10,000, and 20,000 puffs). The themes are cosmetic, changing the screen's colour scheme and animation style without affecting any wattage or pod settings.

These features give the G4 Pro a daily carry quality that satisfies experienced vapers, while remaining structured enough for a switcher to get set up correctly within a few minutes.

Choosing the Right Nicotine Strength

The pod resistance you choose shapes everything: airflow, vapour volume, and which nicotine strength actually works for your habits. Use this table as a starting point if you're using the G4 Pro to move away from cigarettes.

Nic salts are formulated to deliver nicotine more smoothly than freebase, producing a softer throat hit even at higher strengths. That makes them particularly well suited to the tighter MTL draw of the 0.9Ω and 1.2Ω GPP pods. The UK legal limit for nicotine-containing e-liquid is 20mg - all products at Vaping 101 comply with this.

Browse nic salts by strength or explore our 50/50 e-liquids to find the right match for your setup.

First Use - Getting the Best from Your G4 Pro

A few straightforward steps before your first vape will protect the coil, extend pod life, and get you better flavour from the start.

• Prime the pod: Fill a new pod and leave it to sit for 5-10 minutes before firing. This lets the wick saturate fully and prevents dry hits on the first draw
• Start low: Begin at the lower end of the recommended wattage range for your pod resistance and increase gradually until you find your preference
• Watch the liquid level: Keep e-liquid above the minimum fill line at all times. Running a pod dry is the fastest way to burn the coil
• Replace the pod when flavour drops: A muted or slightly burnt taste is the pod telling you it needs replacing - not the device
• Screen navigation: Swipe up to unlock the screen, swipe down to access the settings menu, and swipe left or right to browse themes

Dry hits from an unprimed pod are the most common reason first-time users think a device isn't working. The 5-10 minute wait before firing is worth it every time.

Compare the Caliburn G4 Range

The G4 Pro is the only model in the Caliburn range with a full colour touchscreen and the Custom Mode power curve. The standard G4 shares the same maximum output and pod platform but relies on button navigation and offers no wattage curve control. For vapers who want maximum control over how each draw feels, the Pro is the clear choice.
