If you’ve ever looked for a reliable pod system, you’ve probably come across UWELL at some point. UWELL has been around long enough that most vapers already know what to expect: clean flavour, simple designs, and devices that rarely need babysitting.
The Caliburn series is one of the reasons for that reputation. It focuses on pod systems that are easy to use while still offering enough flexibility to suit different vaping styles. In this guide, we’re looking specifically at two popular models in the lineup: the Caliburn G3 and the Caliburn X, which are often compared but built with different priorities in mind.
UWELL Caliburn G3: Straightforward, Reliable, and Low Maintenance
The UWELL Caliburn G3 is designed for vapers who want a dependable daily device without unnecessary complexity. It supports both MTL and restricted RDL vaping, which makes it easy to adapt depending on pod choice and airflow.
Because the device runs on a 900 mAh battery and reaches up to 25W, it provides enough power for consistent flavour while staying within a range that works well with nicotine salts.
What you’ll notice in regular use
- 2 mL pod capacity, which suits compact pod systems
- Adjustable power output, allowing some control without overwhelming settings
- Magnetic pod connection, which keeps the pod secure
- Leak-resistant pod design, reducing common pod-related mess
- USB-C charging, making recharging quicker and more convenient
- 0.6Ω and 0.9Ω pod compatibility, covering both warmer and tighter draws
Most users choose the 0.6Ω pod when they want slightly stronger vapour and warmth, while the 0.9Ω pod works better for a classic MTL experience that feels closer to a cigarette.
The G3 suits beginners because it stays simple, and it suits experienced users because it doesn’t get in the way.
UWELL Caliburn X: More Control for Dial-In Users
The UWELL Caliburn X is aimed at vapers who prefer adjusting their settings rather than leaving everything automatic. It remains compact enough for daily carry, although the added features make it slightly larger than the G3.
This model includes an OLED screen, which displays wattage, battery level, and coil resistance so users can see exactly how the device is performing.
Key features in practice
- 2 mL pod capacity
- Adjustable wattage, allowing finer tuning
- Top-fill pod design, which simplifies refilling
- Stable chipset, keeping output consistent
- USB-C charging
- 0.8Ω and 1.2Ω pod compatibility, focusing on smoother MTL performance
The 0.8Ω pod offers a balance between flavour and vapour, while the 1.2Ω pod produces a cooler, milder vape that pairs especially well with nicotine salts.
If you like knowing your wattage and adjusting output manually, the X makes more sense than the G3.
G3 vs X: Which One Should You Choose?
Instead of repeating specifications, the difference comes down to how you vape:
-
Portability and Simplicity
The G3 stays lighter and more minimal, which suits users who want something they can just fill and use. -
Customization and Control
The X provides adjustable wattage and screen feedback, which appeals to users who like fine-tuning. -
Battery Use
Both last comfortably through a day for most users, although the X’s settings flexibility lets you manage power more precisely.
Both models support button-activated and draw-activated vaping, so the experience feels familiar regardless of which one you pick.
Choosing the Right Pod Resistance
Pod resistance affects warmth, throat hit, and vapour output more than most people expect.
Caliburn G3
- 0.6Ω for a warmer vape with more vapour
- 0.9Ω for a balanced, tighter MTL draw
Caliburn X
- 0.8Ω for slightly stronger flavour and vapour
- 1.2Ω for a smoother, lower-intensity vape
E-Liquid Compatibility Notes
This is worth keeping in mind when setting up your device:
-
Nicotine Salt (10–20 mg)
Works best in low-to-mid wattage pod systems, including the Caliburn series. -
Freebase Nicotine (3–6 mg)
Designed for higher-power tank systems, such as Geekvape Aegis L200.
Because pod systems are open refill designs, they are naturally more prone to minor leakage than disposables or closed pods. Using nicotine salt in high-power tank systems should be avoided, since thinner liquid can leak more easily. Freebase nicotine can work in pod systems, although flavour intensity may feel weaker.
Final Thoughts
The UWELL Caliburn series continues to appeal to vapers who value flavour consistency and ease of use. The Caliburn G3 works best for users who want something simple and dependable, while the Caliburn X suits those who prefer more control over wattage and output.
Choosing the right pod resistance and e-liquid will shape the experience far more than the device itself, and both models handle that balance well.
