The Uwell Caliburn Koko Prime is a compact CRC open pod system with a multi airflow system that changes draw resistance between restricted DTL and MTL by reversing the pod direction, allowing you to enjoy freebase e-liquids or nicotine salts with one device.

Koko Prime Kit

The Uwell Caliburn Koko Prime has a buttonless ergonomic square frame that fits comfortably in either hand with a lanyard loop for added portability, highlighted by replaceable magnetic panels on each side, housing a 690mAh internal cell with maximum output of 15W, USB C charging, and a multicolor battery indicator which displays the charge level during use or while plugged in. The Caliburn G/Koko Prime pod series is cross compatible and the puff activated Uwell Caliburn Koko Prime delivers the same new dual airflow system as the Caliburn G which allows you to change the draw resistance by reversing the pod. When the one sided bottom air inlet is near the single intake channel on the device, the airflow is suitable for restrictive direct to lung vaping. When you turn the pod so the air inlet is on the opposite side of the device from the intake, the airflow becomes more restrictive and suitable for mouth to lung vaping.

This new pod series has capacity for 1.6mL of e-liquid and a built in coil. The pod included has a 1.0Ω atomizer rated for 10 - 15W, and pods with a 0.8Ω mesh coil rated for 13 - 18W are sold separately. The removable mouthpiece covers a large top fill port that integrates a press to fill spring loaded automatic lock that prevents leaks, and makes filling a breeze.
