Please contact our support team at support@kandypens.com with pictures of your device and charge port. The charge port is naturally supposed to be receded slightly into the device, but you may have sustained damage to your charge port if you are having difficulty charging the device.

This usually indicates a poor connection between your cartridge and your battery. Try to rotate the cartridge inside the device, adjust the magnetic adapter alignment, and clean connection area and you should see instant results.

It seems silly, but the device is usually powered off. Once the device finishes charging, the light will go off to indicate it is no longer charging. Press the button on your device five times as quickly as you can, and the device will power on!

The C-box pro is compatible with cartridges sporting a diameter of less than 10.55mm. If you are unsure, please contact support.
