UWELL CALIBURN G4 KIT

UWELL CALIBURN G4 KIT – Premium Pod System for Serious Vapers

The UWELL Caliburn G4 Kit delivers a smooth nicotine experience optimized for salt nic up to 20mg, perfect for ex-smokers switching to vaping or anyone craving reliable, hassle-free daily vaping. With a powerful 1300mAh battery, adjustable airflow, dual firing modes, and an HD color display, the G4 is the most refined Caliburn pod system yet.

What Makes the Caliburn G4 Special?

The Caliburn G4 isn’t just an update—it’s a complete rethink of what a pod system should be. UWELL took feedback from years of G-series success and added what was missing: bigger battery, smarter display, real airflow control, and pods that actually last longer without leaking or losing flavor mid-week.

Unlike its predecessors, the G4 introduces dual firing modes (Storm and Waves), adjustable airflow that you control via a physical slider or by flipping the pod itself, and a 0.85-inch HD color screen with animated themes. The battery jumps to 1300mAh—35% larger than the G3—so you can vape all day without hunting for a charger.

Design & Build Quality – Pocket-Friendly Without Compromise

The G4 weighs just 48 grams and fits naturally in your palm or pocket thanks to its durable aluminum alloy body with rounded corners and a subtle ridged grip. The design feels premium without being fragile—it’s built to take a knock during commutes or outdoor breaks.

The 0.85-inch HD color OLED display is legible in sunlight and offers a dynamic user interface with two distinct themes: switch between vibrant animated screens or a classic black-and-white interface depending on your mood. Battery indicator, wattage readout, puff counter, and mode status all display clearly. You can adjust brightness too, so screen brightness never drains battery unexpectedly.

Battery, Charging & Real-World Runtime

The 1300mAh battery is a game-changer for all-day users. On moderate use, expect a full day of vaping before needing to recharge. Heavy vapers may need an evening top-up, but you’ll never be stranded mid-session like with smaller pod systems.

USB-C fast charging delivers full power in about 45 minutes with the included 2A cable. The screen shows charge status in real-time, so you know exactly when your device is ready. No guessing, no surprises.

Airflow Control – Three Ways to Dial Your Draw

This is where the G4 shines for vapers who care about consistency. You get three independent airflow adjustment methods:

• Airflow slider – Physical slider on the device body for instant draw tightness adjustment from restricted MTL to loose lung hits
• Pod orientation – Flip the pod 180 degrees to access a different airflow channel built into the cartridge itself
• Coil resistance – Swap between included 0.4Ω, 0.9Ω coils (and compatible G3 pods) to further fine-tune draw resistance and vapor production

Combine slider position + pod orientation and you unlock multiple distinct vaping profiles from a single device. Tight MTL smoker’s draw in the morning, looser RDL vape at lunch—no need to carry two devices.

Performance with Salt Nicotine – Smooth, Satisfying Hits

Load your 20mg salt nic liquid into the G4 and adjust to tight MTL airflow for maximum throat hit without harshness. The UWELL Pro-FOCS 4.0 flavor technology ensures every puff tastes consistent and vibrant—no flavor fade mid-session.

The new U² coil technology (ultrasonic welding + U-shaped airflow channel) distributes heat evenly, preventing dry hits and burnouts that plague older pod systems. Pods now last 35% longer than G3 cartridges while delivering better flavor throughout their lifespan.

Storm Mode delivers a punchier, more aggressive hit favored by salt nic users. Waves Mode smooths out the draw for flavor-chasing or all-day comfort. Switch between them with a double-click and find your sweet spot.

Pod Compatibility & Filling

The G4 accepts both UWELL Caliburn G3 pods and the newer GPP cartridges designed specifically for the G4. Both fit magnetically and hold 2–3ml of e-liquid depending on the model.

Filling is dead simple: pop the pod cap from the top, fill through the wide opening (no fiddly needles required), and snap it back into place. There’s also a side-fill option if you prefer. The clear-view juice window lets you see your e-liquid level at a glance—no more surprise dry hits.

The GPP pod design features an improved seal and leak-resistant build, so your pocket stays dry even if you accidentally tilt the device. Each kit includes two pre-installed coils (0.4Ω and 0.9Ω), so you can experiment with draw resistance right out of the box.

Modes & Power Delivery

Storm Mode and Waves Mode represent UWELL’s take on personalized vaping profiles. Storm delivers consistent, full-power output for dense vapor and strong nicotine delivery. Waves mode softens the hit and optimizes for smooth flavor waves. Both modes maintain steady wattage (up to 35W) across the full battery charge—no performance drop as the battery depletes.

The intuitive control scheme uses simple button clicks: power on/off, mode switching, and airflow adjustment all happen without menu diving. New vapers figure it out immediately; experienced vapers appreciate the straightforward interface.

Available Colors – Find Your Style

The Caliburn G4 comes in six distinct colorways, so you can match your device to your vaping personality or wardrobe:

• Glacier Blue – Cool, crisp aesthetic perfect for summer vibes
• Gunmetal Grey – Classic, professional look that works everywhere
• Polar Black – Timeless dark finish, hides minor scuffs
• SeaShell White – Clean and minimalist, stands out in a crowd
• Twilight Silver – Modern, sleek metallic tone
• Karst Grey – Sophisticated earthy grey for understated elegance

All colors feature the same premium aluminum alloy construction and identical performance. Choose based on personal preference—your vaping experience won’t change, but your device will look exactly how you want it to.

Is the Caliburn G4 an Upgrade for You?

If you’re using an older Caliburn G, G2, or G3, the G4 delivers real improvements: longer battery, smarter display, better airflow control, improved pods, and refined flavor delivery. You’ll notice longer sessions, more consistent flavor, and fewer maintenance headaches.

New vapers coming from cigarettes will appreciate how the tight MTL draw mimics a traditional smoke while delivering nicotine satisfaction without the tar, ash, or smell.

Cloud chasers may find the G4 too restrictive for RDL—consider a sub-ohm tank if you want big vapor. But for anyone prioritizing flavor, battery life, and reliability, the G4 is hard to beat at this price point: just 9 BHD at VapeShop.bh.

Daily Usage Tips for Maximum Performance

• Prime new pods – Fill and wait 5 minutes before your first puff to avoid dry hits
• Clean contacts weekly – Wipe the pod connection and device contacts with a dry cloth to maintain consistent firing
• Use proper e-liquids – Salt nic up to 20mg works best; freebase works but lacks the punch MTL vapers expect
• Rotate pods every 1–2 weeks – Flavor will fade gradually; swap for a fresh pod to reset
• Match coil to liquid – 0.9–1.2Ω for salt nic, 0.4Ω for freebase or lower nic strength
• Lock the screen – Double-click to prevent accidental firing in your pocket

Frequently Asked Questions

How long does the battery last on a single charge?

On moderate use, you’ll get a full day. Heavy vapers might need a top-up in the evening, but the 1300mAh capacity is significantly larger than earlier Caliburn models. USB-C fast charging refills it in roughly 45 minutes.

Can I use the G4 with freebase e-liquid?

Yes, the G4 works with freebase vape juice, but it’s optimized for salt nicotine. Freebase at high strength (18–24mg) tastes harsh in the G4’s tight MTL airflow. Lower freebase (3–6mg) works smoother for lung-hitting, but salt nic delivers the smoothest experience overall.

Are Caliburn G3 pods compatible with the G4?

Yes. The G4 accepts both G3 pods and the newer GPP cartridges. Both fit magnetically. The GPP pods are slightly improved with better leak resistance and slightly longer lifespan, but G3 pods work perfectly fine too.

What’s the difference between Storm Mode and Waves Mode?

Storm Mode delivers consistent, full-power output for a punch and denser vapor. Waves Mode optimizes for a smoother, more balanced hit with emphasis on flavor smoothness. Switch between them based on your mood or time of day.

Is the Caliburn G4 leak-proof?

The G4 uses UWELL’s U² welding technology to minimize leaks, and it’s dramatically better than older pod systems. That said, no device is 100% leak-proof if you overfill or store it horizontally for days. Fill to the line, keep contacts clean, and you’ll rarely see leaks.

How many puffs do I get per pod?

Pod lifespan depends on wattage and frequency, but expect 1–2 weeks of daily use before flavor noticeably fades. The GPP pods last about 35% longer than older G3 cartridges.

Can I adjust the wattage on the Caliburn G4?

The G4 supports full wattage adjustment from 5–35W controlled via the display, so you can fine-tune power delivery to your coil and liquid. Most MTL users stay in the 12–18W range for balanced flavor and throat hit.
