4. Operating Instructions

The Onerbl AC-DC Adapter operates by converting alternating current (AC) from your wall outlet to direct current (DC) suitable for your device. It is designed for continuous operation when connected to a power source and a compatible device.

• Ensure the adapter is securely plugged into both the wall outlet and the device.
• Monitor your device's charging indicator to confirm proper function.
• Avoid covering the adapter during operation to allow for proper ventilation.

5. Maintenance

• Cleaning: Disconnect the adapter from all power sources before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or solvents.
• Storage: Store the adapter in a cool, dry place when not in use. Avoid wrapping the cable too tightly to prevent damage.
• Inspection: Periodically inspect the adapter and cable for any signs of damage, such as frayed wires or cracked casing. If damage is found, discontinue use immediately.

6. Troubleshooting

If you encounter issues with your Onerbl AC-DC Adapter, refer to the following common solutions:

• Device Not Charging:
  • Ensure the adapter is fully plugged into both the wall outlet and the device.
  • Verify the wall outlet is functional by testing it with another device.
  • Check the adapter's cable and connector for any visible damage.
  • Important Note: Rechargeable batteries have a limited lifespan (typically 1 to 3 years). If the battery itself is damaged or has reached the end of its life, it may not accept a charge, even with a functional adapter. This is not an issue with the charger.
• Adapter Feels Warm: It is normal for the adapter to feel slightly warm during operation. If it becomes excessively hot or emits a burning smell, disconnect it immediately and discontinue use.
• Loose Connection: Ensure the barrel connector is firmly seated in the device's port.
