With more than a dozen Caliburn models on the shelf, picking the right one can feel daunting. The best Caliburn to buy depends on you: choose the simple A series or original for fuss free beginner vaping, the G3 for the best balance of flavour and control. For a screen and full adjustability, the G3 Pro and Caliburn X are the picks. This buyer's guide walks you through the decision step by step.

If you want the full lineup first, our guide on the Caliburn range explained compares every model. Our guide on the best Caliburn for beginners goes deeper for new vapers.

Start with how you vape

The right Caliburn comes down to a few honest questions about how you actually want to vape. Are you brand new to vaping and want something that just works? Or are you an experienced vaper who likes to tinker with settings? Do you want a tight, cigarette like MTL draw? Or would you prefer a looser, airier draw with bigger clouds? How heavily do you vape through the day, plus how much would you like to spend? Answer those four questions and the choice narrows quickly, since each Caliburn is pitched at a slightly different kind of vaper. There is no single best model, only the best one for you.

If you are a beginner

If you are new to vaping or switching from cigarettes, simplicity matters more than features. The A series, such as the A2 and A3S, is ideal here, offering draw activated firing with little or nothing to adjust, pre installed mesh coils and a tight MTL draw that feels close to a cigarette. The original Caliburn is similarly straightforward if you find one. These models let you fill, prime and vape with no settings to learn, which is exactly what most beginners want. You can always move up to a more advanced model later once you know your preferences.

If you want the best all rounder

For most people, the Caliburn G3 is the sweet spot of the range and the easiest model to recommend. It pairs the Caliburn's signature flavour with a 900mAh battery, USB-C fast charging, an OLED screen, adjustable wattage up to 25W and adjustable airflow, yet it stays simple enough for a confident beginner. It works for a tight MTL draw or a slightly looser one depending on the pod, so it grows with you. If you are not sure where to start and want one device that does almost everything well, the G3 is the safe, sensible choice that rarely disappoints.

To weigh the options up, the Uwell Caliburn collection lists every current model with its specs, so you can compare batteries, pods and features side by side.

If you want power and features

If you are an experienced vaper who enjoys fine tuning, the top of the range rewards you. The Caliburn G3 Pro pushes output to 35W, adds a large full screen interface, a smooth slider for airflow and a bigger battery for all day use, making it great for both flavour and slightly bigger clouds. The Caliburn X is the other enthusiast pick, combining full wattage and airflow control with a roomy 3ml pod and a premium feel. Reviewers tend to advise against these as a first vape, since their extra features are wasted on a beginner, yet for a confident vaper they offer the most flexibility in the range.

Pen shape or KOKO box?

Many Caliburns come in two body shapes, with the choice mostly about feel. The classic pen style, slim and rectangular, is what most people picture and slips easily into a pocket. The KOKO models take the same internals and wrap them in a square, boxy shape, often with a lanyard loop and swappable decorative panels, which some find comfier to hold and easier to grip. Performance is essentially identical between a model and its KOKO version, so pick whichever shape you prefer in the hand. It is purely an ergonomic and style decision rather than a performance one.

A word on budget and pods

Two practical points round off the decision. On budget, the simpler models and the G3 Lite are the most affordable, often under fifteen pounds for the device, while the G3 Pro and X command a higher price for their extra features. On pods, remember that Caliburn pods are model specific and not interchangeable across families, so factor in the ongoing cost and availability of the right pods for whichever device you choose. Our guide on the true cost of owning a Caliburn breaks down what each model actually costs to run over a year.

Should you upgrade an older Caliburn?

If you already own an older Caliburn, the question shifts from which to buy to whether an upgrade is worth it. The honest answer is that older models still vape well, so there is no urgency to replace a device that is doing its job. That said, the jump from an original or G2 to a G3 brings a real improvement in battery life, charging speed and convenience, with an OLED screen and adjustable wattage added for the same sort of money. If your current device frustrates you with short battery life or slow charging, an upgrade pays off, whereas if it suits you fine there is little reason to change.

It is also worth thinking about pods when upgrading, since moving between families means buying new pods rather than reusing your old ones. Staying within the same family, for example going from a G3 to a G3 Pro, keeps your existing pods compatible, which saves a little money and hassle. If you are happy with your draw and just want more battery or a screen, a sideways step within the family is the cheapest route. Our comparison of the Caliburn G2 versus G3 goes into exactly what changes between those popular generations.

The bottom line

The best Caliburn to buy is the one that matches how you vape. Beginners and switchers are best served by the simple, cheap A series or original. The G3 is the standout all rounder, balancing flavour, control and value for almost anyone. The G3 Pro and Caliburn X suit experienced vapers who want power, a screen and full adjustability. Decide on your experience level, draw style, usage and budget first, then the right Caliburn will become obvious. Whichever you choose, the flavour and reliability are guaranteed.
