4. Setup
Follow these steps to set up your UpBright AC/DC Adapter:
- Verify Compatibility: Ensure your device is an EICOBOT A10 or A-10 High Efficiency Stick Cordless Vacuum Cleaner. This adapter is specifically designed for these models.
- Inspect the Adapter: Before first use, visually inspect the adapter and cable for any signs of damage. Do not use if damaged.
- Connect to Device: Insert the barrel round connector of the adapter cable firmly into the charging port of your EICOBOT vacuum cleaner.
- Connect to Power Outlet: Plug the AC adapter into a standard wall power outlet (100-240VAC).
- International Use (if applicable): If you are in a region requiring a different plug type (e.g., AU, EU, UK), attach the appropriate outlet adapter (only one is included per international order) to the AC adapter before plugging it into the wall outlet.

5. Operating Instructions
Once the adapter is properly connected, the EICOBOT vacuum cleaner's battery will begin charging. Observe the charging indicator on your vacuum cleaner for charging status.
- Allow the battery to fully charge for optimal performance.
- Do not leave the adapter plugged in indefinitely after the battery is fully charged, although the adapter includes overcharge protection.
- The adapter is designed to provide a stable 26.5VDC output at 500mA for efficient charging.

6. Maintenance
Proper maintenance ensures the longevity of your adapter:
- Cleaning: Disconnect the adapter from the power outlet and the device before cleaning. Use a soft, dry cloth to wipe the surface. Do not use liquid cleaners or solvents.
- Storage: Store the adapter in a cool, dry place when not in use. Avoid wrapping the cable too tightly around the adapter to prevent damage.
- Cable Care: Regularly check the cable for any cuts, fraying, or bends. If damage is observed, discontinue use immediately.
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 vacuum cleaner.
- Check if the wall outlet is functional by plugging in another device.
- Inspect the adapter cable and connector for any visible damage.
- Note: Rechargeable batteries have a limited lifespan (typically 1 to 3 years). If the vacuum cleaner's battery is old or faulty, it may not accept a charge, which is not an issue with the charger itself.
- Adapter Overheating: While the adapter has built-in overheat protection, ensure it is used in a well-ventilated area and not covered during operation. If it consistently overheats, discontinue use.
