The Uwell Caliburn A3S Pod Kit is a premium, compact vape system that combines portability, high flavour output, and beginner-friendly operation in one device. Part of Uwell’s renowned Caliburn series, the A3S is designed for users who want a smooth, consistent Mouth-To-Lung (MTL) vaping experience without complicated controls or bulky hardware.
Engineered with premium aluminium alloy, the device is both durable and stylish, fitting comfortably in the hand or pocket. The draw-activated mechanism eliminates buttons entirely, letting users enjoy a truly hassle-free vaping experience. The 520mAh built-in battery ensures consistent all-day use, while USB-C fast charging minimizes downtime.
The refillable 2ml pods feature integrated mesh coils and Uwell’s Pro-FOCS flavour technology, delivering rich, balanced vapour with each inhale. The improved side-fill port reduces the risk of spills, and the leak-resistant design ensures a clean, mess-free vaping experience. Ideal for both nicotine salts and 50/50 VG/PG e-liquids, the Caliburn A3S is perfect for beginners transitioning from smoking, as well as seasoned vapers who value convenience, reliability, and high-quality flavour.
