The Uwell Caliburn X Pod kit has a modern, fashionable design. It is simple to use and provides an MTL (Mouth To Lung) inhalation, this is a good option for novice vapers. The authentic Uwell Caliburn X 20W Pod System has a built-in 850mAh battery, a 5-to-20W output range, and it works with both G and G2 Coils. The Caliburn X Pod System's chassis, made of a sturdy aluminum alloy, provides a sturdy and resilient chassis against minor dips and drops. The reusable pods also use a juice viewing glass to ensure a minimum fill level to prevent any dry hits or coil burning, and they can store up to 3ml of liquid. Each kit comes with a Caliburn X refillable pod with a mesh coil already installed and a spare for improved flavor.
