Design and Build Quality

The Caliburn G3 has adopted a different design approach compared to its predecessors. The pods are now larger, holding 2.5ml of e-liquid, providing a bit more capacity for users. It’s important to note that the G3 has now moved to integrated coils within the pods, which means that you can no longer just replace the coil itself; instead, you have to replace the entire pod when it’s time for a new coil. This has its pros and cons, but it’s a noteworthy change in the design.

Two new coil types are available: a 0.9-ohm coil designed for mouth-to-lung (MTL) vaping, and a 0.6-ohm coil intended for a restricted direct lung (RDL) experience. This allows you to choose the coil that best suits your personal vaping preference.

Filling the Caliburn G3’s pod is simple, thanks to a bottom-fill rubber plug design. Just open the plug, insert your e-liquid, close the plug, and ensure to let it sit for five minutes to fully saturate the cotton before use. Although some may miss the top-fill feature of previous models, it’s a minor change in the filling process.

Regarding airflow control, the Caliburn G3 offers a unique solution where you can reverse the position of the pod inside the device to either increase or decrease the airflow depending on your preference.

The device itself is slightly taller and wider than its G2 counterpart, but it still feels just as comfortable in hand. With a 900mAh battery and a Type-C charging port, it offers ample power for daily use.

A noteworthy additional feature is the haptic feedback when inserting or removing the pod, which provides a subtle vibration for users.

In summary, the Caliburn G3’s design and build quality offer several improvements, although it also introduces some design changes that may be subjective to individual users’ preferences. Overall, these changes make it an excellent choice for those seeking flexibility in coil options, increased e-liquid capacity, and adjustable airflow options in this latest Caliburn device.


To fill your pod, locate the rubber plug on the side and open it. Carefully pour your e-liquid, ensuring not to overfill the 2.5 mL capacity. Close the plug securely when you’re finished. It’s a good idea to let the pod sit for around five minutes, allowing the cotton to become fully saturated with e-liquid.

After your pod is filled and its cotton has been saturated, you’ll want to attach it to the device. The pod is designed with two airflow openings on opposite sides, allowing you to control your airflow. Just insert the pod into the device with the desired airflow orientation, either more open for a looser draw or with less exposure for a more restricted draw.


When the pod is attached, press the fire button five times to power on the device. You’ll see the display come to life, showing you the wattage, puff counter, and resistance. If you want to reset your puff counter, press the fire button four times quickly. To change the wattage, triple-click the fire button and select your desired wattage, going up to a maximum of 25 watts with the 0.6 Ohm coil and 15 watts with the 0.9 Ohm coil.

Remember, the device has a smart resistance check, which means it automatically limits the maximum wattage based on the coil you’re using. For example, when using a 0.9 Ohm coil, you’ll be limited to a 15-watt maximum. If you want to lock your fire button, double-click it rapidly, and double-click again to unlock.

Now you can enjoy your vaping experience, whether you prefer mouth-to-lung (MTL) or restrictive direct lung (RDL) vaping. Adjust the wattage accordingly and make use of the different airflow settings to suit your preferences.


The G3 offers a noticeably enhanced flavor, making your vaping experience more enjoyable. The device has a satisfying feel in hand, with a comfortable fire button. Its larger size compared to the original does not detract from the overall experience, maintaining the familiar “caliburn” feeling.

You can customize your experience by adjusting the wattage of the device. Fine-tuning the power output lets you cater to different vaping preferences, from a stronger hit to a more mellow draw. Along with this, the G3 provides several smart features, such as a puff counter that is resettable by the user, and automatic resistance detection.

The G3 allows for versatile airflow control by simply reversing the pod. You can choose between tighter, mouth-to-lung (MTL) draws or looser, restricted direct lung (RDL) hits. This feature caters to both novice and experienced vapers, ensuring optimal satisfaction for your individual preferences.

Comparison with Predecessor Devices

The G3 has some noticeable differences compared to the G2. Firstly, the G3 has a 2.5 mL e-liquid capacity, allowing for more liquid in the pod. The G3 also offers the option to use strictly auto-draw without needing the fire button, which is a convenient feature. Another advantage of the G3 is the ability to fine-tune and adjust the wattage, which was not available in the G2.

However, there are some changes in the G3 that might not appeal to everyone. For instance, the G3 no longer features a top-fill design, which was a popular feature in the G series. Furthermore, the coils in the G3 are not replaceable, making the pods more of a throwaway item.

Another thing to consider is the mouthpiece, which is slightly wider on the G3. Depending on personal preferences, some users may prefer the smaller mouthpiece on the G2.

When it comes to flavor, the G3 coils are said to offer improved flavor compared to the G2. The difference in flavor might not be significant, but it is noticeable when testing the devices side by side. The mixed berry flavor, for example, comes across as slightly more pronounced in the G3.

In terms of airflow, the G3 provides more control and customization, allowing for both tighter and looser mouth-to-lung (MTL) vaping experiences. This is a significant advantage for users who want to fine-tune their vaping experience.

Overall, the G3 has some improvements over the G2, but it also comes with trade-offs. The choice between the two devices ultimately depends on personal priorities and preferences.



The flavor enhancement of the new G3 is noticeable but not so dramatic that you would need to transition to it immediately. However, if you are looking for a device with better flavor delivery, the G3 may be a good option. Airflow control, adjustable wattage, and the option to use auto draw all contribute to a positive vaping experience with the G3.

In conclusion, the G3 has a few minor drawbacks, but the advantages certainly outweigh them. It is a worthy option in the market for those seeking improved flavor, airflow control, and customizable wattage settings in their vaping experience.
