How to fill the Caliburn X Pod

To fill the device, simply remove the drip tip from the pod. You can then fill the tank with your favourite OK Vape E-Liquid, through the red filling port. Once the pod is full, it can then be capped with the drip tip.


How to replace the coil in your Uwell Caliburn X

You'll need to change you coil when you notice a deterioration in flavour or experience a burnt taste. Depending on how much you vape, you'll probably need to change your coil every 1-3 weeks.

To replace the coil, simply remove the pod from the battery and remove the coil from the bottom of the pod. A new coil can then be inserted into pod, lined up with the cutouts. Please ensure the pod is empty before changing the coil. Once you've replaced the coil, fill your pod up with e-liquid and leave it to stand for at least five minutes before vaping to prime the coil.

Please see below for Uwell’s wattage ranges for the different resistance coils:

0.8 ohm: 13-18W

1 ohm: 10-15W

1.2 ohm: 9-13W
