2. Safety Information
Always observe the following safety precautions to reduce the risk of fire, electric shock, or injury:
- Use the adapter only with compatible devices as specified.
- Do not expose the adapter to water, moisture, or extreme temperatures.
- Do not disassemble or modify the adapter.
- Ensure the adapter is plugged into a properly grounded outlet.
- Unplug the adapter from the power source when not in use or during electrical storms.
- Keep out of reach of children.
This adapter features built-in protection mechanisms:
- OVP (Over Voltage Output Protection): Protects against excessive output voltage.
- OCP (Over Current Output Protection): Protects against excessive output current.
- SCP (Short Circuit Output Protection): Protects against short circuits.

3. Product Overview
The UpBright 31V AC/DC Adapter is a reliable power supply designed for specific vacuum cleaner models. It converts AC wall power to the DC voltage required by your device.

4. Setup
Follow these steps to set up your UpBright AC/DC Adapter:
- Verify Compatibility: Ensure your device (e.g., Buture Pro BP10 vacuum cleaner) is compatible with a 31V DC power input. Note: The vacuum's battery voltage (e.g., 25.9V) is different from the charger's output voltage (31V). This is normal for charging circuits.
- Connect to Device: Insert the barrel round connector of the adapter cable firmly into the charging port of your vacuum cleaner or its battery charging base.
- Connect to Power Outlet: Plug the AC prongs of the adapter into a standard wall power outlet (100-240VAC, 50/60Hz).
- Charging Indication: Refer to your vacuum cleaner's manual for specific charging indicators (e.g., LED lights) to confirm that charging has begun.

5. Operating Instructions
Once connected, the adapter will begin charging your device's battery. The charging time will depend on the battery's capacity and its current charge level. Always allow the battery to fully charge for optimal performance.
Important Note on Batteries: Rechargeable batteries have a limited lifespan, typically 1 to 3 years. If an old or faulty battery does not accept a charge, this is generally a battery issue, not a charger malfunction.
6. Maintenance
To ensure the longevity and proper functioning of your adapter:
- Keep the adapter clean and free from dust. Use a dry, soft cloth for cleaning.
- Store the adapter in a cool, dry place when not in use.
- Avoid bending or crimping the cable excessively.
- Regularly inspect the cable and connector for any signs of damage. Discontinue use if damage is observed.

7. Troubleshooting
If you encounter issues with your adapter, consider the following:
- Device not charging:
- Ensure the adapter is securely plugged into both the wall outlet and the device.
- Check if the wall outlet is functional by plugging in another device.
- Inspect the adapter cable and connector for any visible damage.
- If the device's battery is old or faulty, it may no longer accept a charge. Consider replacing the battery if it's past its typical lifespan.
- 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, unplug it immediately and discontinue use.
