Common Issues and Solutions:
- Power bank not charging: Ensure the charging cable and adapter are working correctly and properly connected. Try a different cable or adapter.
- Device not charging from power bank: Check if the power bank has sufficient charge. Ensure the cable connecting your device to the power bank is functional and securely connected. Try a different port or cable.
- Slow charging: Verify that your device and cable support fast charging. Ensure the power bank has enough charge. Some devices may limit charging speed if they are too hot or cold.
