2. Safety Information
Please read and understand all safety instructions before using the adapter. Failure to follow these instructions may result in electric shock, fire, or other hazards.

- Protection Features: The adapter is equipped with OVP (Over Voltage Output Protection), OCP (Over Current Output Protection), and SCP (Short Circuit Output Protection) to ensure safe operation and protect your device.
- Environmental Conditions: Use the adapter in a dry environment. Avoid exposure to water, moisture, or extreme temperatures.
- Ventilation: Ensure adequate ventilation around the adapter during use. Do not cover it with cloths or other materials.

5. Operating

- Its advanced power management chips ensure efficient and safe power delivery.
6. Maintenance
Proper care will extend the life of your UpBright AC/DC Adapter:
- Cleaning: Disconnect the adapter from both the power outlet and your device before cleaning. Use a soft, dry cloth to wipe the surface. Do not use liquid cleaners or solvents.
- Storage: When not in use, store the adapter in a cool, dry place, away from direct sunlight and moisture. Avoid tightly winding the cable to prevent damage.
- Handling: Do not drop, disassemble, or attempt to repair the adapter yourself. This can void the warranty and pose safety risks.
7. Troubleshooting
If you encounter issues with your UpBright AC/DC Adapter, refer to the following common problems and solutions:
- Device Not Charging:
- Ensure the adapter is securely plugged into both the wall outlet and the massage gun.
- Test the wall outlet with another device to confirm it is functional.
- Verify that your massage gun's battery is not at the end of its lifespan. Old or faulty batteries may not accept a charge, which is a limitation of the battery, not the adapter.
- Confirm that the massage gun model (e.g., Cotsoco m679) is compatible with this 8.4V 1A adapter.
- Adapter Feels Hot: It is normal for the adapter to feel slightly warm during operation. If it becomes excessively hot or emits a burning smell, immediately unplug it from the power source and discontinue use. Contact customer support.
- Loose Connection: If the barrel connector feels loose in the device's port, ensure it is fully inserted. If the issue persists, the device's port or the adapter's connector may be worn.
