Safety Features:
This adapter incorporates multiple professional protection features to ensure safe charging:
- OVP (Over Voltage output Protection): Prevents damage from excessive output voltage.
- OCP (Over Current output Protection): Protects against damage from excessive output current.
- SCP (Short Circuit output Protection): Safeguards against short circuits.

4. Maintenance
Proper maintenance ensures the longevity and optimal performance of your UpBright AC/DC Adapter.
- Cleaning: Disconnect the adapter from the power source and the device before cleaning. Use a dry, soft cloth to wipe the surface. Do not use liquid cleaners or abrasive materials.
- Storage: Store the adapter in a cool, dry place away from direct sunlight and extreme temperatures. Avoid tightly coiling the cable to prevent damage.
- Cable Care: The adapter features a flexible and durable TPE material wire. Avoid sharp bends, kinks, or excessive pulling on the cable, as this can damage internal wiring.

5. Troubleshooting
If you encounter issues with your UpBright AC/DC Adapter, refer to the following common troubleshooting steps:
- No Power/Charging:

- Verify the wall outlet is functional by testing it with another appliance.
- Check if the device itself is functioning correctly with its original charger (if available).
- Slow Charging:
- Confirm the device is fully compatible with the adapter's output specifications (15V, 1A).
- Ensure the adapter and device are not in an excessively hot environment, which can affect charging efficiency.
- Adapter Overheating:
- While some warmth is normal, excessive heat may indicate an issue. Disconnect immediately.
- Ensure adequate ventilation around the adapter during use.
- The adapter has good heat resistance, but prolonged use in confined spaces can lead to heat buildup.
If issues persist after following these steps, please contact UpBright customer support.
