The Uwell Caliburn X Pod kit has a contemporary, stylish appearance. This is a wonderful alternative for new vapers as it is easy to use and offers MTL (Mouth To Lung) inhalation. With a built-in 850mAh battery, a 5-to-20W output range, and compatibility with both G and G2 Coils, the authentic Uwell Caliburn X 20W Pod System offers powerful vaping. The aluminum alloy chassis of the Caliburn X Pod System offers a strong and durable structure against slight dips and drops. The refillable pods can hold up to 3ml of liquid and employ a juice viewing glass to ensure a minimum fill level to avoid any dry hits or coil burning. Every package includes a Caliburn X refillable pod with an already-installed mesh coil and an extra for better flavor.
