Introduction
This manual provides instructions for the safe and efficient use of your UpBright 31V AC/DC Adapter. This power supply unit (PSU) is designed to charge various Laresar Elite series cordless stick vacuum cleaners, including models Elite 1, Elite 3, Elite 4, Elite 5, and Elite Pro, which utilize a 25.9V Li-ion battery pack.
Setup Instructions
Follow these steps to properly set up your AC/DC adapter:
- Select the Correct Outlet Adapter: The package includes one suitable regional outlet adapter (EU, UK, or AU) to fit your country/area. Attach the appropriate adapter to the main AC/DC adapter unit.

Ensure a secure connection.
- Connect to Power Outlet: Plug the AC input side of the adapter into a standard wall power outlet (100-240VAC, 50-60Hz).
- Verify Charging: Refer to your vacuum cleaner's manual or indicator lights to confirm that it is charging correctly.
Operating Instructions
This AC/DC adapter is designed for straightforward operation to charge your compatible Laresar vacuum cleaner.
- Charging Process: Once connected as described in the Setup section, the adapter will begin supplying power to charge the vacuum cleaner's internal battery. The charging duration will depend on the battery's current charge level and the specific Laresar model.
- Voltage Compatibility: Please note that the vacuum cleaner's battery voltage (e.g., 25.9V) is different from the charger's output voltage (31V). The charger is specifically designed to provide the correct voltage and current for safe and efficient charging of the 25.9V Li-ion battery packs found in compatible Laresar models.
- Automatic Protection: The adapter features built-in Over Voltage Protection (OVP), Over Current Protection (OCP), and Short Circuit Protection (SCP) to ensure safe charging and protect both the adapter and your vacuum cleaner from electrical damage.
Maintenance
To ensure the longevity and optimal performance of your AC/DC adapter, follow these maintenance guidelines:
- Keep Dry: Always keep the adapter in a dry environment. Avoid exposure to water or high humidity, which can damage internal components.
- Clean Gently: If cleaning is necessary, disconnect the adapter from all power sources and wipe it with a soft, dry cloth. Do not use liquid cleaners or abrasive materials.
- Proper Storage: When not in use, store the adapter in a cool, dry place, away from direct sunlight and extreme temperatures. Avoid tightly coiling the cable to prevent damage.
- Inspect Regularly: Periodically check the adapter and its cable for any signs of damage, such as cuts, fraying, or bent pins. Discontinue use if any damage is found and replace the adapter.
Troubleshooting
If you encounter issues with your AC/DC adapter, consider the following:
- No Charge Indication:
- Ensure the adapter is securely plugged into both the wall outlet and the vacuum cleaner.
- Check if the wall outlet is functioning by plugging in another device.
- Verify that the correct regional plug adapter is firmly attached.
- Battery Not Accepting Charge: Rechargeable batteries have a limited lifespan (typically 1 to 3 years). If your vacuum cleaner's battery is old or dead, it may not accept a charge, even if the charger is working correctly. This is a battery issue, not a charger issue.
- Testing the Charger: To determine if the charger is functioning, you must use a voltmeter to check its output voltage. A working charger should output approximately 31V DC. If it does not, the charger may be faulty.
- Overheating: If the adapter feels excessively hot during use, disconnect it immediately and allow it to cool. Ensure it is used in a well-ventilated area and not covered.

User Tips
- Battery Lifespan: Be aware that rechargeable batteries typically last 1 to 3 years. If your vacuum cleaner is not charging, first consider the age of its battery. An old or dead battery will not accept a charge, and this is not an issue with the charger itself.
- Verify Charger Functionality: If you suspect the charger is faulty, use a voltmeter to test its output. A working charger should show an output of approximately 31V DC.
