Uwell Caliburn A2S: simple draw-activated MTL
Quick answer: the Caliburn A2S is a compact 15W refillable pod device built around a 520mAh battery and a 2ml side-fill 1.2Ω A2S cartridge. It has no firing button or settings menu: fill the correct pod, allow the wick to saturate, then inhale to activate. Buyers comparing compact refillable devices can see the full pod systems range.

Who is this device for?
The A2S suits adults who want a narrow pen-format kit and a tighter MTL draw without adjustable wattage. It is materially simpler than screen-equipped devices such as the Caliburn G3 and the Caliburn G4 Pro. The trade-off is less battery capacity and fewer controls.
Pod compatibility and filling
Use cartridges made for the Caliburn A2/A2S/AK2 platform; do not assume G-series or GPP cartridges fit. Open the side silicone plug, fill through the intended port, close it firmly and let a new pod stand before the first draw. Wipe condensation from the contacts and use our pod leaking guide if liquid collects beneath the cartridge.
What is included?
Uwell’s standard A2S kit specification includes the device, two 1.2Ω A2S pods, a USB Type-C cable, lanyard and user manual. Regional packs can vary, so the sealed box is the final reference. E-liquid is not assumed to be included; browse UAE e-liquids separately.
