The Caliburn G was the first model in the Caliburn line to introduce replaceable coils, allowing users to change only the coil instead of the entire pod. This innovation lowered long-term vaping costs and added more customization to the series.
Design and Build Quality
One of the reasons the Caliburn lineup became popular is its simple but refined design.
The Caliburn G keeps the same slim “vape pen” style as the original model but improves the structure with better grip and durability. The device is built from zinc alloy, making it lightweight but resistant to minor drops and everyday wear.
Key design highlights
- Ribbed surface improves grip
- Lightweight and pocket-friendly
- Clear e-liquid viewing windows
- Click-fit pod connection for secure attachment
Compared to the original Caliburn, the G model features small refinements such as a more tactile fire button and improved mouthpiece shape, making it more comfortable during daily use.
Overall, the device strikes a good balance between portability and durability, which explains why many users keep it as their everyday carry vape.
Ease of Use: A Beginner-Friendly Device
The Caliburn G is designed for simplicity. Unlike complex vape mods that require settings and adjustments, this device works almost immediately after setup.
Setup process
- Install the coil into the pod
- Fill the pod through the top-fill port
- Wait 5–10 minutes for the coil to soak
- Turn on the device with five clicks
After that, users can vape by either pressing the button or simply inhaling.
This dual firing system is especially helpful for beginners who want a cigarette-like vaping experience.
Performance Review: Flavor, Vapor, and Throat Hit
Performance is where the Caliburn G truly stands out.
Flavor Quality
The UN2 Meshed-H coil heats e-liquid evenly, producing consistent flavor with every puff.
Many reviewers consider the Caliburn G’s flavor output one of the best in its category, especially for nicotine salts and 50/50 e-liquid blends.
Vapor Production
At 18 watts of power, the device produces a warm and satisfying vapor without becoming too intense.
This makes it ideal for:
- Mouth-to-lung vaping
- Smooth restricted lung hits
Throat Hit
The tighter airflow combined with mesh coils produces a strong throat hit, which many former smokers prefer.
Dual Airflow System Explained
Instead of a traditional airflow slider, the Caliburn G uses a clever trick.
You can change airflow simply by reversing the pod orientation.
- One orientation → tighter MTL draw
- Opposite orientation → slightly looser draw
Both options remain within the mouth-to-lung vaping style, but the difference is noticeable enough for users to customize their experience.
This simple design avoids extra parts while still offering flexibility.
Coil System and Longevity
The Caliburn G uses replaceable coils rather than disposable pods.
Coil options
- 0.8Ω Mesh Coil – warmer vape, stronger flavor
- 1.0Ω Coil – smoother and cooler draw
Coil lifespan
Most users report coils lasting 1 to 2 weeks, depending on the sweetness of the e-liquid and usage frequency.
Cost advantage
Replaceable coils make the Caliburn G more economical than many pod devices because you only replace the coil instead of the entire cartridge.
Battery Life and Charging
The Caliburn G runs on a 690mAh built-in battery, which is larger than many compact pod systems.
Battery performance
- Light users → full day
- Moderate users → almost full day
- Heavy users → may need recharge
The device can vape through roughly 3 ml of e-liquid before needing a recharge, depending on usage.
Charging speed
The USB-C port charges the battery in about 45 minutes, making it convenient for quick top-ups.
Pod System and Leak Resistance
Leakage is one of the most common issues with pod vapes, but the Caliburn G handles this well.
Why it rarely leaks
- Secure top-fill system
- Tight coil installation
- Solid pod sealing
The design prevents common issues such as spit-back or gurgling, which many users appreciate.
One minor drawback is that the mouthpiece can feel slightly stiff when removing it for the first few refills.
Real-World Daily Use Experience
After long-term use, the Caliburn G proves to be a dependable device.
What stands out in daily use
- Fits easily in pockets
- Minimal maintenance
- Coils are easy to replace

Many vapers keep the Caliburn G as a backup device, even if they upgrade to newer models.
Its reliability is one of the reasons it remains popular years after its release.
