UWELL has become one of the most respected names in pod vaping, and the Caliburn series is widely regarded as one of the benchmarks for MTL vaping in the UK.
Among the latest versions is the UWELL Caliburn G3 - a compact refillable pod kit designed for smooth airflow, strong flavour and simple everyday use. It has become especially popular with:
- adult smokers switching to vaping
- disposable vape users moving to refillables
- nic salt users
- MTL vapers looking for reliable flavour performance
In this guide, we review the UWELL Caliburn G3, explain how to set it up correctly and help you choose the best Vampire Vape e-liquids for your device.
What Is the UWELL Caliburn G3?
The UWELL Caliburn G3 is a rechargeable refillable pod vape designed primarily for MTL (mouth-to-lung) vaping.
Compared to larger sub-ohm kits, the Caliburn G3 focuses on:
- compact portability
- simple operation
- nic salt compatibility
- flavour clarity
- smooth adjustable airflow
The device uses refillable pods with integrated coil options, making maintenance simpler than traditional vape tanks with replaceable coils.

Flavour Performance
One of the biggest reasons the Caliburn series became so popular is flavour quality.
The G3 is designed to deliver:
- clean flavour reproduction
- smooth nicotine delivery
- consistent airflow
- efficient coil performance
Compared to many basic pod kits, the Caliburn G3 is often praised for producing richer flavour from nic salt e-liquids.
Airflow and Draw Style
The adjustable airflow system allows users to customise the inhale style.
Tighter airflow settings are ideal for:
- cigarette-style MTL vaping
- stronger throat hit
- higher nicotine strengths
Looser airflow settings work better for:
- restricted DTL vaping
- warmer vapour
- lower nicotine strengths
This flexibility makes the G3 suitable for a wider range of adult vapers than many fixed-airflow pod systems.
Battery Life
The Caliburn G3 offers strong battery performance for a compact pod kit.
USB-C charging also allows:
- faster recharge times
- more reliable charging
- easier everyday use
For most MTL users, battery life is usually sufficient for a full day of moderate vaping.
Other Caliburn G3 Kits Worth Considering
If you like the Caliburn G3 but want a different style or feature set, Uwell also offers several newer versions in the same family:
Uwell Caliburn G3 Pro
The G3 Pro builds on the original G3 with a larger display, increased power output and a more premium design. It’s a good choice for vapers who want more control over their settings while keeping the same excellent flavour performance.
Uwell Caliburn G3 Lite
The G3 Lite is a simpler, lightweight version designed for easy everyday vaping. It keeps the refillable pod system and smooth draw of the G3 while removing some of the more advanced features.
Uwell Caliburn G3 Pro KOKO
The G3 Pro KOKO uses the same G3 pod platform in a compact box-style design. Its larger battery and portable shape make it popular with users who want a pocket-friendly alternative to the standard stick-style device.
All three devices remain compatible with the Caliburn G3 pod platform, making it easy to switch between models while continuing to use your preferred pods and e-liquids.
Why the Caliburn G3 Is So Popular for Nic Salts
The Caliburn G3 is especially well suited to nic salts because of its:
- MTL airflow design
- lower wattage operation
- efficient coil resistance
- smooth inhale style
Higher-resistance pod options - including tighter MTL setups - work particularly well with 50VG/50PG nic salt e-liquids.
This combination helps provide:
- smoother nicotine delivery
- strong flavour
- efficient battery usage
- reduced e-liquid consumption
For many adult vapers moving away from disposables, the Caliburn G3 feels like a natural transition device.
How to Set Up the UWELL Caliburn G3
Setting up the Caliburn G3 is straightforward, but proper preparation helps improve flavour and coil lifespan.
Step 1: Fill the Pod
Remove the pod from the device and open the refill port.
Fill the pod with a compatible e-liquid, ideally:
- nic salts
- 50VG/50PG e-liquid
- MTL-friendly blends
Avoid overfilling.
Step 2: Prime the Coil
After filling the pod for the first time, allow it to sit for around 5–10 minutes before vaping.
This helps the coil absorb e-liquid properly and reduces the risk of dry hits or coil damage.
Step 3: Insert the Pod
Insert the filled pod securely into the device.
The magnetic connection should hold the pod firmly in place.
Step 4: Adjust the Airflow
Adjust the airflow to suit your preferred inhale:
- tighter airflow for MTL vaping
- looser airflow for restricted DTL vaping
Best E-Liquids for the UWELL Caliburn G3
The Caliburn G3 performs best with:
- nic salts
- 50VG/50PG freebase e-liquids
- MTL-focused blends
High-VG shortfills are generally not ideal for tighter Caliburn pod setups because thicker liquids can reduce wick efficiency and coil lifespan.

- Pinkman Nic Salts
- Strawberry Kiwi Nic Salts

Most adult vapers switching from disposables to the Caliburn G3 begin with either 10mg or 20mg nic salts.
