Troubleshooting
If you encounter issues with your CSODINCE 40W USB C Charger Block, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not charging. | Loose connection, faulty cable, incompatible device, power outlet issue. | Ensure charger is firmly plugged into the wall. Check cable connections at both ends. Try a different cable. Test the power outlet with another device. Verify device compatibility. |
| Slow charging speed. | Using non-fast charging cable, multiple devices connected, device not supporting fast charge. | Use a high-quality cable designed for fast charging. Disconnect other devices to allow maximum power to a single device. Ensure your device supports PD or QC fast charging. Note that charging speed may slow down when the device's battery is above 60%. |
| Charger feels warm. | Normal operation, heavy load. | It is normal for the charger to become warm during operation, especially when charging multiple devices or fast charging. If it becomes excessively hot or emits smoke/odor, immediately unplug it and discontinue use. |
| Charger ports not working. | Debris in port, internal fault. | Inspect ports for debris and gently remove if present (with charger unplugged). Try a different port. If issue persists, contact customer support. |
