Uwell's Caliburn A3S epitomises elegance and efficiency in a refillable pod vaping kit. Equipped with a robust 520mAh inbuilt battery, the A3S offers the convenience of swift recharging via a USB-C cable (which is not provided). Its design is both slim and sophisticated, featuring an aluminium body with intricate laser detailing. Remarkably user-friendly, it operates without a fire button; simply inhale to activate the device.
Included with the kit are two A3S refillable pods (one 0.8ohm and the other 1.0 ohm, both with mesh coils) that allow you to enjoy your preferred e-liquid. Refilling is a breeze: push against the mouthpiece to remove it, add e-liquid to the side port, secure the leak-proof closure, and reattach the mouthpiece.
For optimal performance, we suggest using e-liquids with a maximum of 60% VG, like those from the Bar Juice or ElfLiq range. The pods should be replaced when the flavour diminishes. Thanks to the kit's prominent e-liquid window, it's easy to monitor when a refill is needed.
The kit is available in a variety of colours and is compatible with both A3S and Caliburn A3 coils.
The Caliburn A3S Vape Kit works best with 50/50 VG/PG e-liquids, thin enough to wick efficiently through compact MTL coils and consistent enough to deliver clean flavour at lower wattages. It is built exclusively for mouth-to-lung vaping, with coil resistances spanning from 0.8Ω to 1.0Ω across a 16W output range. Nicotine salt e-liquids are the natural choice at these resistance levels, delivering a smooth, satisfying throat hit at higher nicotine strengths without harshness, which suits the tighter draw of MTL vaping particularly well. Freebase e-liquids at 3mg or 6mg also work well if you prefer a lighter nicotine hit.
Each pod holds 2ml of e-liquid and uses a side fill system, keeping refilling straightforward and mess-free. High-VG liquids such as 70/30 blends are generally not recommended for tighter MTL pods, as thicker e-liquid can struggle to wick efficiently at lower wattages and may lead to dry hits.
