2. Safety Information
To ensure safe operation and prevent damage, observe the following safety precautions:
- CAUTION: RISK OF ELECTRIC SHOCK. DRY LOCATION USE ONLY. This adapter is intended for indoor use in dry environments. Do not expose to water, moisture, or high humidity.
- Ensure the adapter's input voltage (100-240V 50-60Hz) matches your local power supply.
- Do not attempt to disassemble, modify, or repair the adapter. Refer all servicing to qualified personnel.
- Keep the adapter away from heat sources, direct sunlight, and flammable materials.
- Inspect the power cord and adapter for any signs of damage before each use. Do not use if damaged.
- This adapter is equipped with safety protection mechanisms: OVP (Over Voltage output Protection), OCP (Over Current output Protection), and SCP (Short Circuit output Protection) to safeguard your device.
- Important Note: The 25.9V mentioned for the vacuum cleaner refers to its battery voltage, not the charger's output voltage. This adapter provides a 30V output, which is correct for charging the 25.9V battery.
3. Setup
Follow these steps to set up your Acdctek 30V AC/DC Adapter:
- Unpack: Carefully remove the adapter from its packaging.
- Connect to Power Outlet: Plug the adapter's AC input plug into a standard wall power outlet (100-240V AC, 50/60Hz).

4. Operating Instructions
Once properly connected, the adapter will begin supplying power to your Fieety Elite 9-US vacuum cleaner. If the vacuum cleaner is turned off, it will typically begin charging its internal battery.
- Observe the charging indicator on your vacuum cleaner (if available) to confirm that charging is in progress. Refer to your vacuum cleaner's manual for specific charging indicator behavior.
- Disconnect the adapter from the vacuum cleaner once charging is complete or when the vacuum is not in use for extended periods.
- Always unplug the adapter from the wall outlet when not in use.
5. Maintenance
Proper care and maintenance will extend the life of your adapter:
- Cleaning: Disconnect the adapter from both the power outlet and the vacuum cleaner before cleaning. Use a soft, dry 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.
- Inspection: Periodically inspect the adapter's casing, power cord, and connectors for any signs of wear, cuts, or damage. If any damage is found, discontinue use immediately and replace the adapter.
6. Troubleshooting
If you encounter issues with your Acdctek 30V AC/DC Adapter, refer to the following common troubleshooting steps:
- No Power/Not Charging:
- Ensure the adapter is securely plugged into a working wall outlet. Test the outlet with another device.
- Verify that the DC output connector is fully inserted into the vacuum cleaner's charging port.
- Check the adapter's cable for any visible damage or kinks.
- Confirm that the vacuum cleaner itself is functioning correctly and its battery is not completely depleted or faulty.
- Adapter Overheating:
- It is normal for adapters to become slightly warm during operation. However, if the adapter becomes excessively hot, disconnect it immediately.
- Ensure adequate ventilation around the adapter and avoid covering it.
