UWELL CALIBURN G4 PRO KIT

Take full control of your nicotine delivery with the Caliburn G4 Pro, a touchscreen pod system built for vapers who demand precision over everything else. Whether you vape salt nicotine at 20mg, switch between devices, or adjust your setup based on mood and time of day, this kit adapts to your style—not the other way around.

Caliburn G4 Pro Kit: Three Distinct Power Delivery Modes for Salt Nic and Beyond

The standout feature is choice across three firing modes. Storm Mode cranks output hard from the first draw—ideal if you vape salt nic and want that fast, cigarette-like throat hit. The device fires at maximum wattage right away, sustaining that intensity throughout the entire puff. This is the path for ex-smokers chasing instant nicotine satisfaction with a tight MTL draw. Waves Mode takes the opposite approach: it ramps power up slowly, letting the flavor develop and deepen across the whole draw. This mode suits vapers who prefer smoother, more complex flavor profiles—especially those using lower-strength salt nic or who occasionally switch to freebase liquids in a pod. Custom Mode is where the engineering truly shines. You adjust the power curve at three distinct points during each puff: start, middle, and end. Want a gentle ramp-up into a harder mid-puff hit, then a soft taper toward the finish? Done in seconds via the 2.51-inch touchscreen. Want maximum power the entire draw? One tap. The display is high-resolution, shatterproof, and bright enough to use outdoors without squinting. Each mode delivers a visibly different experience—you’ll see exactly which curve you’ve selected before you draw, so there’s no guesswork.

This approach to power delivery is uncommon in pod systems. Most devices lock you into a single output profile. The Caliburn G4 Pro recognizes that vapers need flexibility: your ideal experience on a Monday morning (strong throat hit to wake up) differs from Friday evening (smooth, complex flavor). The three modes, combined with a 5–35W wattage range, mean you’re not buying a static device—you’re buying a tool that evolves with your habits.

Stepless Airflow, Coil Options, and Pod Compatibility for Precise MTL Control

The G4 Pro ships with two coil options: a 0.4Ω coil for tight MTL draws and a 0.6Ω coil for slightly more open airflow. This gives you immediate flexibility out of the box. The 0.4Ω coil is the MTL sweet spot if you vape 20mg salt nic—the high resistance pairs with Storm Mode to deliver that sharp throat hit and quick nicotine onset. The 0.6Ω opens things up, lowering heat and spreading vapor delivery across a longer draw, which works well if you prefer Waves Mode or occasionally use freebase nicotine. Beyond coil choice, stepless airflow control means you’re not locked into a fixed draw restriction. The airflow collar adjusts smoothly from fully closed to fully open, so you can tighten it for a cigarette-like restriction if you want maximum TH, or open it wider for a more relaxed, airy pull. This is critical for MTL vapers: different salt nic brands, different VG/PG ratios, and even different ambient humidity levels can shift your ideal airflow sweet spot. Stepless control lets you dial that in without swapping coils.

The 3mL pod capacity uses Uwell’s CALIBURN GPP (G Pod Platform) cartridges, and the fill system is side-fill with a clear e-liquid viewing window. Side-fill means you never remove the pod from the device to refill—it stays magnetically connected and perfectly positioned. U² Anti-Leak Technology prevents the messy leaks that frustrate users of cheaper pod systems; the seal is tight even if you overfill slightly or accidentally tip the device. The pod connection is magnetic and rock-solid—no wobbling, no intermittent disconnections mid-vape. The magnetic contact is flush and consistent, so every puff fires cleanly.

Battery Endurance, Charging Speed, and Real-World Use Scenarios

The 1800mAh integrated battery lasts up to seven days on moderate usage, though heavy users (30+ puffs per hour, all day) may need to charge every other day. USB-C charging is fast and standard across modern devices. For salt nic users, consider this: if you vape 12mg or 20mg salt nic, your usage pattern is often shorter sessions (a hit or two, then break). This means the 1800mAh stretches far. Heavy vapor chasers using Waves Mode at higher wattage will deplete the battery faster. Battery Saver Mode, toggled from the touchscreen, extends endurance on days you’ll be away from a charger.

The device pairs seamlessly with both nicotine salt e-liquids (up to 20mg) and standard freebase liquids. Ex-smokers transitioning to vaping should start with Storm Mode + a 0.4Ω coil + 20mg salt nic—this combination delivers the fastest nicotine hit and most familiar throat sensation. Flavor chasers should experiment with Waves Mode, a 0.6Ω coil, and lower-strength salt nic (12mg or less) or freebase, depending on how much vapor production you want. The ergonomic, contoured mouthpiece is smooth and designed for hours of comfortable vaping. The touchscreen includes brightness adjustment, screen timeout settings, animation toggles, and a puff counter reset—all accessible in one tap. Six UI themes ship with the kit; three unlock immediately, three more unlock at usage milestones. This is thoughtful design that keeps the device feeling fresh.
