The Caliburn Pod System uses both button and draw activation and comes with a built-in 520mAh battery with 1A charging via a micro USB port on the base. The pod has a 2ml capacity with a 1.4 ohm coil. The Caliburn features an LED battery indicator and a nice big firing button. This is a great device that will go with you anywhere.
The Uwell Caliburn Replacement Pods are disposable consumable parts and as such over time will need to be replaced to maintain a great vaping experience. Typically a coil will last 1 - 2 weeks before it will need to be replaced.
