Introduction
The vaping world is evolving at a fast pace, and Uwell is consistently at the forefront of innovation. Their Caliburn series has built a reputation for exceptional performance, sleek design, and user-friendly features. In this Uwell Caliburn AK3 Review: Compact and Reliable, we’ll explore why this pod kit has quickly become a favorite for both beginners and experienced vapers. We’ll examine its design, performance, coil quality, battery life, and ease of use, while also comparing it to previous models in the Caliburn lineup.
Whether you’re looking for a portable vape to carry anywhere or a reliable daily driver, the AK3 offers a strong balance of convenience, flavor, and quality.
Design and Build Quality
The Caliburn AK3 stands out for its ultra-compact profile without compromising on performance. Its boxy yet sleek frame fits comfortably in your palm or pocket, making it ideal for on-the-go vaping. Weighing just around 35g, it’s extremely lightweight yet feels solid in the hand thanks to its aluminum alloy construction.
Uwell has refined the design with smooth edges, an embossed Caliburn logo, and an LED indicator for battery and draw status. Available in multiple colors, the AK3 also features a lanyard attachment, which adds practicality for those who want quick access without pocket clutter.
The magnetic pod connection ensures a snug fit while allowing easy removal for refilling or coil changes. The top-fill system minimizes leaks, which is a big plus for anyone tired of messy refills.
Ease of Use
The AK3 is as straightforward as it gets—perfect for beginners who want a hassle-free vaping experience. It’s a draw-activated device, meaning there are no buttons to press. Simply inhale, and the device does the rest.
Refilling is quick and clean thanks to the flip-top cap design. Just snap it open, fill your e-liquid, and close it securely. The transparent pod makes it easy to monitor your e-liquid levels, helping to avoid dry hits.
Maintenance is minimal—there are no complex settings or modes to adjust. Simply swap out the pod when the coil is burnt or flavor diminishes.
Performance and Flavor Quality
Performance is where the AK3 truly shines. Equipped with Uwell’s Pro-FOCS flavor technology, the device delivers pure, rich flavor with every puff. The technology recycles drawn air through the atomizer, enhancing taste while prolonging coil life.
The AK3 uses Caliburn A3 refillable pods with built-in 1.0Ω mesh coils. This resistance is perfect for mouth-to-lung (MTL) vaping, providing a satisfying throat hit and excellent nicotine delivery—especially for salt nic users.
Vapor production is smooth and consistent, with no spit-back or dry hits when used properly. The mesh coil heats evenly, producing warm vapor that captures the full profile of your e-liquid.
Battery Life and Charging
The AK3 is powered by a 520mAh built-in battery, which is impressive for its size. For light to moderate vapers, a single charge can last an entire day. Heavy vapers may need to top up in the evening, but that’s where the fast charging feature comes in.
With USB-C charging, the AK3 can reach 90% battery in just 20 minutes. The LED indicator lets you know your current battery status: green for high, blue for medium, and red for low. This eliminates guesswork and ensures you’re never caught without power.
Comparing the AK3 to Previous Caliburn Models
If you’ve used earlier Caliburn devices, you’ll notice some clear upgrades in the AK3. Compared to the original Caliburn and Caliburn KOKO, the AK3 offers:
