The Uwell Caliburn is a pod kit offering excellent performance in a beautifully thin and light design.
The chassis of the device is made from sturdy but lightweight aluminum alloy, with a matte finish giving Caliburn a luxurious feel resistant to dirt and finger oil.
The dual-firing mechanism is a rarity, giving the user an option between puff-activation and button-activation. Pods may be filled with up to 2mL of liquid, one of the largest capacity in the market for the Caliburn's form factor (J***L in comparison has less than 1mL per pod).
Caliburn's coil uses Uwell's proprietary Pro-FOCS technology, directing airflow along the coil several times before output in order to express the flavor of liquids as accurately as possible.
Another highlight feature is the 520mAh battery. Given Caliburn’s size and the coil’s power efficiency, the battery allows for longer use between charges versus comparable devices. What's more, the built-in battery is replaceable at the user's option.
