The Uwell Caliburn G was released as a follow-up to the highly successful original Caliburn, aimed at vapers seeking a reliable and versatile pod system. With significant design and performance upgrades, it is tailored for users wanting a fulfilling mouth-to-lung (MTL) vaping experience. The introduction of replaceable coils marks a pivotal shift, making it appealing to both new and seasoned vapers looking for customization and convenience.

This review is based on a synthesis of insights from multiple credible sources, including Vaping360, BEST VAPE, and myvpro.com. Each source provides details on the Caliburn G's performance, specifications, and comparisons with its predecessor and competing devices on the market. By analyzing these findings, I aim to present a balanced view of the Caliburn G's capabilities and potential drawbacks.

Overall, the Uwell Caliburn G receives high praise for its enhanced vapor production and ease of use, making it a strong contender in the pod system category. However, some users have noted minor design flaws, such as limited e-liquid capacity and concerns regarding the mouthpiece comfort. These aspects should be weighed against its commendable performance and customizable features.

How user-friendly is the Caliburn G?

The Uwell Caliburn G maintains a compact design with dimensions of 108.3 mm x 22.5 mm x 12.6 mm and a weight of just 60 grams, making it extremely portable. Its intuitive one-button operation simplifies the vaping experience, while the adjustable airflow feature provides versatility, allowing users to customize their draw style easily.

Unlike its predecessor, which required completely new pods when the coil wore out, the Caliburn G introduces a replaceable coil system. Users can now easily swap out the 0.8-ohm UN2 Meshed-H coils, extending the lifespan of the device and minimizing waste, which many vapers find appealing.

Does the Caliburn G deliver on vapor production?

The Caliburn G operates at a maximum wattage of 18 watts, a substantial increase from the original's 11 watts. This enhancement yields better flavor and vapor production, catering specifically to MTL users who appreciate rich, warm hits. Users have reported a satisfying throat hit that does not compromise on flavor depth.

The introduction of meshed coils represents a significant technological improvement in this model, allowing for more efficient e-liquid vaporization. This leads to lesser frequent refills, contributing to overall user satisfaction.

How does the Caliburn G compare in terms of build quality?

Constructed from durable PCTG material and aluminum alloy, the Caliburn G boasts a premium feel while ensuring reliability. It also retains the original Caliburn's sleek aesthetics with several color options, appealing to a wide array of users seeking both style and durability.

However, some users have expressed discomfort with the mouthpiece design, finding it less ergonomic than expected. A few complaints regarding the e-liquid capacity of 2 mL also surfaced, especially for heavy users, who feel that more frequent refills disrupt their vaping experience.

Is the Caliburn G worth its price?

Given its range of features and improvements over previous models, the Uwell Caliburn G delivers strong value for vapers who appreciate customizable experiences. The replaceable coils and advanced vapor production certainly justify its position as a reputable choice among its peers.

When comparing to alternatives like the Voopoo Vinci and the Vaporesso XROS, the Caliburn G stands out with its user-friendly coil system and MTL-focused design. Each competitor brings unique features, but the Caliburn G balances performance and practicality well.
