The Uwell Caliburn G4 Pro is the first Caliburn with a full 2.51" shatterproof touchscreen — and it's not just a spec-sheet number. Every core function runs through the screen: wattage, vaping modes, themes, puff counter, and settings. No multi-click button combos to memorize. 1800mAh battery, 35W max output, 3 vaping modes (Storm, Waves, Custom), stepless airflow, and full compatibility with GPP and G3 pods. Available in 8 colours.

The Touchscreen Changes Everything
Previous Caliburn devices used button clicks to cycle through settings — 2 clicks for this, 3 for that, 5 to power off. The G4 Pro replaces all of that with one-tap touchscreen controls. Tap to adjust wattage. Tap to switch modes. Swipe down for settings. It's the kind of interface you'd expect on a phone, not a pod kit.
The screen also supports device renaming via an on-screen keyboard, 6 animated UI themes (3 are unlockable through puff milestones), adjustable brightness, screen timeout, and 8 language options. It's the most customizable Caliburn ever made.
Three Vaping Modes
Storm Mode delivers instant, punchy output for a strong throat hit. Waves Mode provides smooth, consistent power for flavour-focused sessions. Custom Mode is new to the G4 Pro — it lets you set different power levels at the start, middle, and end of each puff, creating a custom wattage curve. All three modes are accessible with a single tap on the touchscreen.

Pod Compatibility & E-Liquids
The G4 Pro works with all Caliburn GPP pods (0.4Ω, 0.6Ω, 0.9Ω, 1.2Ω) and G3 pods. If you already own pods from a Caliburn G3, G4, G5 Lite, or any GPP-compatible device, they'll work here. Refilling is mess-free — the side-fill port means you don't need to remove the pod.
Salt nic (10–20mg) pairs best with 0.6Ω and above for MTL. Freebase (3–6mg) works well with the 0.4Ω pod for RDL. Browse our salt e-liquids and freebase e-liquids.

Frequently Asked Questions
What pods does the Caliburn G4 Pro use?
All Caliburn GPP pods (0.4Ω, 0.6Ω, 0.9Ω, 1.2Ω) and G3 pods. The kit includes one 0.4Ω and one 0.6Ω GPP pod. If you have pods from a Caliburn G3, G4, or G5 Lite device, they're compatible.
How does the touchscreen work?
One-tap to adjust wattage, switch modes, or reset the puff counter. Swipe down for the settings menu (themes, brightness, language, device rename). It's a 2.51" shatterproof screen — no multi-click button sequences needed.
What's Custom Mode?
Custom Mode lets you set different power levels at the start, middle, and end of each puff. For example, you could start strong, ease off in the middle, then finish with a boost — creating a personalized wattage curve for each draw.
How is this different from the G4 Pro Koko?
Same internals, different form factor. The
G4 Pro is a pen-style device with an 1800mAh battery and the larger 2.51" screen. The
G4 Pro Koko is a box-shaped device with a larger 2000mAh battery, a 2.0" screen, and a wider body that sits comfortably in the palm. Choose based on your preferred form factor and whether you want more battery (Koko) or more screen (Pro).
How long does the battery last?
1–2 days of typical MTL use. RDL at higher wattage will drain faster. Fast USB-C charging (2.5A) gets you back up quickly.
Can I use salt nic and freebase?
Yes. Salt nic (10–20mg) with 0.6Ω, 0.9Ω, or 1.2Ω pods for MTL. Freebase (3–6mg) with the 0.4Ω pod for RDL.
