Troubleshooting Guide

Power bank is not charging:
Ensure the charging cable is securely connected to both the power bank's USB-C input and a working power adapter. Try a different cable or adapter.
Device is not charging from the power bank:
Check if the power bank has sufficient charge. Ensure the cable connecting the device to the power bank is secure and functional. Try a different port or integrated cable. Verify device compatibility.
Slow charging:
Ensure your device supports fast charging and that you are using a compatible cable. Some devices may limit charging speed to protect their battery. Charging multiple devices simultaneously may also reduce individual charging speeds.
Integrated cable not working:
Inspect the integrated cable for any visible damage. Ensure it is fully inserted into your device. If one integrated cable is faulty, try using the other integrated cable or a separate USB cable with the power bank's ports.
