8. Troubleshooting
If you encounter issues with your Techsmarter Power Bank, please refer to the following common solutions:
| Problem | Possible Cause / Solution |
|---|---|
| Power bank not charging | Ensure the charging cable is securely connected to both the power bank and the wall charger. Use a 45W PD compatible wall charger. Try a different cable or wall charger. |
| Device not charging from power bank | Ensure the power bank has sufficient charge. Press the power button to activate output. Check if the charging cable is securely connected to both the power bank and the device. Try a different port or cable. Ensure your device is compatible with the power bank's output (e.g., 45W PD for laptops). |
| Slow charging | Ensure you are using the correct port for fast charging (USB-C PD or USB-A TS+). The cable used also affects charging speed. Some devices may limit charging speed if they are in heavy use. |
| "Insufficient power supply" error on laptop | Some laptops require a higher wattage than 45W, especially under heavy load. While the power bank provides 45W PD, some laptops (e.g., certain Dell XPS models) may require 65W or more for consistent charging during active use. Try charging the laptop while it is off or in sleep mode. |
| LED indicators not working | Press the power button firmly. If still unresponsive, the unit may be fully discharged or require service. |
