Uwell Caliburn G4 Classic Vape Pod Kit

Description - Uwell Caliburn G4 Classic Vape Pod Kit

The Uwell Caliburn G4 Classic is a refillable pod kit built on a precision CNC-crafted aluminium body, packing a 1400mAh battery with adjustable output up to 35W into a genuinely pocket-friendly form factor. It runs on a dual pod platform that handles everything from tight MTL draws to more open RDL vaping, supported by twin auto-draw sensors, stepless airflow control, and Uwell's PRO-FOCS 4.0 flavour technology. This isn't just a stylish device, it's a capable daily carry that earns its keep through consistent performance.

It suits adult switchers moving away from cigarettes or disposables, everyday vapers after reliable flavour and solid build quality, and anyone who wants more airflow versatility than a basic single-pod kit provides. Available in four colours, it comes with a free nic salt, fast UK dispatch, and Vaping 101's full one-year warranty.

Introducing the Uwell Caliburn G4 Classic

Uwell is one of the most trusted names in pod kit hardware, and the Caliburn G4 Classic sits comfortably near the top of what this price point can deliver. The CNC-crafted aluminium body gives it a premium, solid-in-hand feel that most similarly priced kits simply don't match. The aero-grade build, zirconia-smooth surface finish, and four distinct colour options make it easy to carry without it feeling like a compromise.

Under the hood, the 1400mAh battery and 5W-35W variable output give you a reliable all-day charge for MTL and RDL vaping. The kit ships with two Caliburn G3 pods at different resistances, and it's also compatible with the full range of Caliburn GPP pods. That combination of G3 and GPP compatibility gives this device a genuine flexibility that most pod kits at this price can't offer.

If you want a pod kit that doesn't force you to choose between build quality and performance, the Caliburn G4 Classic is one of the strongest options available right now.

Why Choose the Uwell Caliburn G4 Classic?

The G4 Classic stands out because of how its features work together rather than as a list of individual selling points. Here's a clear breakdown of what you're getting:

• Device style: Refillable pod kit, compact and pocket-friendly with a premium CNC-crafted aluminium body
• Battery and power: 1400mAh built-in battery with 5W-35W adjustable output; Type-C charging at 5V/2A for quick top-ups
• Dual activation: Twin auto-draw sensors with 99.999% trigger accuracy and a 300% longer lifespan than single-sensor kits, plus a micro-pressure fire button. Two clicks locks the button for draw-only use
• Airflow control: Stepless external slider for continuous adjustment from tight to fully open, combined with reversible pod orientation for a secondary layer of fine-tuning
• Pod platform: Compatible with both Caliburn G3 pods and the full Caliburn GPP range (0.4ohm to 1.2ohm), giving you genuine flexibility across resistance and vaping styles
• Flavour technology: PRO-FOCS 4.0 optimises the coil's heating output to protect flavour from the e-liquid rather than burning it, producing a cleaner and more consistent taste
• Leak protection: U² anti-leak pod engineering with a clear e-liquid window to monitor levels
• Status feedback: 14 RGB LEDs colour-coded for battery level: green for high, blue for medium, red for low
• Target vaping style: MTL (mouth-to-lung) and RDL (restricted direct-to-lung). This is not a sub-ohm device
• Best for: Switchers, everyday vapers, and anyone stepping up from a basic single-pod setup
• TPD compliant: 2ml pod capacity, fully UK-legal

The combination of dual pod compatibility and layered airflow control means this kit genuinely grows with your preferences, rather than locking you into one vaping style.

Compatibility and Performance

Getting the most from the Caliburn G4 Classic starts with picking the right pod. The kit includes two Caliburn G3 pods, and both serve different purposes.

Included pods:

• 1 x Caliburn G3 Pod (0.9ohm mesh, MTL) - top-fill, 2ml TPD capacity
• 1 x Caliburn G3 Pod (0.4ohm mesh, RDL/RDTL) - top-fill, 2ml TPD capacity

Extended pod compatibility: Caliburn GPP pods are available separately in 0.4, 0.6, 0.8, 1.0, and 1.2ohm, covering the full MTL-to-RDL spectrum.

Which pod to start with: If you're moving from cigarettes or disposables, or if you're using nic salts (nicotine salt e-liquids designed for higher-resistance, lower-wattage pod kits), start with the 0.9ohm pod. It delivers a tight MTL draw that closely replicates the feel of a cigarette. The 0.4ohm pod is better suited to freebase e-liquids and a more open, airier draw. One important note: using nic salts in the 0.4ohm pod can cause leaking and a harsher, less consistent experience.

Suitable e-liquids by pod:

• 0.9ohm pod: Nic salts (10mg or 20mg) and 50/50 freebase e-liquids
• 0.4ohm pod: 50/50 freebase and higher-VG blends
• GPP pods (0.8ohm and above): Nic salts and 50/50 freebase

Nicotine strength guidance:

• 1-5 cigarettes per day: 5mg nic salt or 3mg 50/50 freebase
• 6-14 cigarettes per day: 10mg nic salt or 6mg freebase
• 15 or more cigarettes per day: 20mg nic salt (the UK legal maximum for nicotine-containing e-liquid)

Charging: Type-C at 5V/2A. Note that no USB-C cable is included in the box, so you'll need a standard one before you can charge.

Pod capacity: 2ml (TPD compliant)

Having GPP pod compatibility alongside the G3 pods means you're not limited to two resistance options. Pick up a pack of Caliburn GPP replacement pods and you can dial in exactly the draw you want without needing a new device.

Uwell Caliburn G4 Classic Highlights

The G4 Classic brings a level of hardware refinement that genuinely stands out at its price point. These aren't just box-ticking features: each one has a practical impact on your daily vaping experience.

• 1400mAh battery with up to 35W output for reliable all-day MTL and RDL use
• Twin auto-draw sensors for consistent activation and a significantly longer sensor lifespan than single-sensor alternatives
• Stepless airflow plus reversible pod for two layers of draw customisation in one compact kit
• PRO-FOCS 4.0 flavour tech fine-tunes coil heating to preserve e-liquid flavour and prevent that burnt, overheated taste
• U² anti-leak pod design with a clear juice window for worry-free carrying and easy liquid monitoring
• 14 RGB LED battery indicator for at-a-glance status without a screen
• CNC-crafted aluminium body available in Classic Black, Classic Silver, Alpine Green, and Abyss Blue

These features work together to make the Caliburn G4 Classic a practical, consistent daily kit, built to deliver from the first puff to the last.

Box Contents

Everything in the box is ready to use straight away. The only thing you'll need before your first fill is a standard USB-C cable for charging.

• 1 x Caliburn G3 Pod (0.4ohm mesh, 2ml)
• 1 x Caliburn G3 Pod (0.9ohm mesh, 2ml)

New to vaping? The 0.4ohm pod comes pre-installed in the device. If you're using nic salts, swap to the 0.9ohm pod before you fill up. It's the better starting point for an MTL draw and will perform more consistently with higher-nicotine e-liquids.
