What is the Uwell Caliburn G4?
The Uwell Caliburn G4 is the latest in Uwell’s iconic Caliburn series. It’s a compact pod vape designed for both MTL (mouth-to-lung) and RDTL (restricted direct-to-lung) vaping. With a 1300mAh battery, adjustable airflow, and a vibrant OLED screen, it promises a premium experience. But does it deliver? Let’s dive in.
Key Features of the Uwell Caliburn G4
First, let’s look at the specs. The Uwell Caliburn G4 boasts impressive features:
● Battery: 1300mAh, lasting up to 1.5 days for moderate vapers.
● Power Output: Adjustable wattage from 5W to 35W.
● Display: 0.85-inch OLED screen with customizable themes.
● Vaping Modes: Storm Mode (intense hits) and Waves Mode (smooth draws).
● Pod Compatibility: Works with G3 and GPP pods (2ml or 3ml capacity).
● Airflow: Adjustable slider for MTL or RTL vaping.
● Charging: Fast Type-C charging (full charge in ~30 minutes).
● Build: Lightweight aluminum alloy, ergonomic design.
These features make the Uwell Caliburn G4 versatile. But how does it perform in real life? Let’s explore.
Design and Build Quality
The Uwell Caliburn G4 is a stunner. Its sleek aluminum alloy body feels premium yet lightweight, weighing just 48g. The rounded corners and ridged texture ensure a comfortable grip. Available in eight vibrant colors, like Flamingo Red and Glacier Blue, it’s stylish without being flashy.
Moreover, the clear juice window lets you monitor e-liquid levels easily. No more guessing when to refill! However, the small screen and tiny buttons may pose challenges for users with vision or dexterity issues. For most vapers, though, the design is practical and portable.
Battery Life and Charging
Next, let’s talk about power. The Uwell Caliburn G4 has a 1300mAh battery, a big upgrade from the G3’s 900mAh. For moderate vapers, it lasts about 1.5 days. Heavy vapers may need a daily charge. Thankfully, the Type-C fast charging gets you back to full in roughly 30 minutes.
However, some users report the battery life feels slightly overstated. Compared to similar devices, it’s solid but not class-leading. Still, the quick charging and passthrough technology (vape while charging) make it convenient for busy lifestyles.
Pod and Coil Performance
The Uwell Caliburn G4 shines in flavor delivery. Thanks to Uwell’s Pro-FOCS 4.0 technology, it offers a 35% boost in flavor and pod lifespan. The kit includes 0.4ohm and 0.9ohm G3 pods, perfect for RDL and MTL vaping, respectively. Additionally, it’s compatible with GPP pods, offering 3ml capacity for longer sessions.
The side-fill system is mess-free, with a silicone plug that’s easy to access. The U² technology (ultrasonic welding and U-shaped airflow) prevents leaks effectively. In our tests at Galaxy Vapers, we found no sputtering or flooding. Each puff was smooth, rich, and consistent, whether using nic salts or freebase juice.
Vaping Experience: Storm vs. Waves Mode
One standout feature is the dual vaping modes. Storm Mode delivers intense, warm hits, ideal for cloud chasers. Waves Mode, on the other hand, offers smooth, steady draws for a relaxed vape. Switching between modes is easy via the OLED screen.
Additionally, the adjustable airflow slider lets you fine-tune your draw. Want a tight, cigarette-like MTL pull? Close the airflow. Prefer a looser RDTL hit? Open it up. This versatility makes the Uwell Caliburn G4 suitable for various vaping styles.
However, the button-firing mechanism feels unnecessary for MTL vapers. Most prefer the draw-activated system, which is precise and responsive. The button’s small size also makes it tricky for some users, especially those with dexterity issues.
User-Friendly Features
At Galaxy Vapers, we value ease of use. The Uwell Caliburn G4 excels here. The draw-activated firing is beginner-friendly—no complex menus to navigate. The OLED screen displays wattage, battery life, and puff count clearly. Customizable themes add a fun touch.
Moreover, the quick-start guide included in the box makes setup a breeze. You’ll be vaping in minutes, even if you’re new to pod systems. However, the small screen and button may frustrate users with vision or motor challenges. For most, though, the G4 is intuitive and hassle-free.
Who is the Uwell Caliburn G4 For?
The Uwell Caliburn G4 caters to a wide audience. Beginners will love its simplicity and consistent performance. Experienced vapers will appreciate the customizable airflow and power modes. However, it’s not ideal for sub-ohm vapers, as it’s not designed for high-VG e-liquids.
Additionally, accessibility is a concern. The tiny screen and buttons make it less suitable for those with vision or dexterity issues. If accessibility is a priority, check out our Galaxy Vapers guide on user-friendly vapes.
