1. Introduction
This manual provides essential instructions for the safe and effective use of your UpBright 31V AC/DC Adapter. This adapter is designed to provide power to specific Laresar Elite series cordless stick vacuum cleaners. Please read this manual thoroughly before use and retain it for future reference.
2. Important Safety Information
To ensure safe operation and prevent damage, observe the following precautions:
- Compatibility: This adapter is designed for direct charging of the vacuum cleaner. It is NOT compatible with charging docks or stations. Ensure the connector type matches your vacuum's charging port.
- Voltage Match: The vacuum's battery voltage (e.g., 25.9V) is different from the charger's output voltage (31V). This is normal for charging Li-ion batteries. Always verify the charger's output voltage matches the required input voltage for your device.
- Protection Features: The adapter includes Over Voltage Protection (OVP), Over Current Protection (OCP), and Short Circuit Protection (SCP) to safeguard your device and the adapter itself.
- Battery Condition: Rechargeable batteries have a limited lifespan, typically 1 to 3 years. If your vacuum's battery is old or faulty, it may not accept a charge, which is not an indication of a charger malfunction.
- Environmental Conditions: Use the adapter in dry conditions. Avoid exposure to moisture, rain, or extreme temperatures.
- Damage Inspection: Do not use the adapter if the cord or plug is damaged. Contact support for a replacement.

6. Operating Instructions
The UpBright AC/DC Adapter operates automatically once connected. It provides a constant 31VDC output to charge your vacuum's battery.
- Charging Time: Charging time will vary depending on the battery's current charge level and capacity. Refer to your vacuum cleaner's manual for estimated charging durations.
- Charging Indicators: Monitor the charging status directly on your Laresar vacuum cleaner, as the adapter itself does not have charging indicators.
- Disconnection: Once the vacuum's battery is fully charged, disconnect the adapter from both the vacuum and the wall outlet.
7. Maintenance
Proper maintenance ensures the longevity and performance of your adapter:
- 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 away from direct sunlight and moisture when not in use. Avoid wrapping the cable too tightly around the adapter to prevent damage.
- Cable Care: Do not bend, twist, or pull the cable excessively. Avoid placing heavy objects on the cable.
