1. Introduction
This manual provides essential information for the safe and effective use of your Onerbl AC-DC Adapter. This adapter is designed as a high-quality replacement power supply for specific Shark ION Robot 725 Series robotic vacuum cleaners. It enables you to power your device or charge its battery from standard electrical outlets.
The Onerbl AC-DC Adapter converts alternating current (AC) from your wall outlet into the direct current (DC) required by your compatible Shark ION Robot vacuum cleaner. It has been tested and validated to ensure compatibility and reliable performance.

6. Troubleshooting
If you encounter issues with your Onerbl AC-DC Adapter, consider the following:
- No Power Indicator Light:
- Ensure the AC power cord is securely connected to both the adapter unit and the wall outlet.
- Verify that the wall outlet is functional by testing it with another device.
- Check for any visible damage to the adapter or cables. If damaged, discontinue use.
- Vacuum Cleaner Not Charging/Powering:
- Confirm the DC output connector is fully inserted into the vacuum cleaner's charging port.
- Ensure the adapter's indicator light is on, indicating it is receiving power.
- Consult your Shark ION Robot's manual for specific charging requirements or troubleshooting steps related to the vacuum itself.
- 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, immediately unplug it from the wall outlet and discontinue use. Ensure it has proper ventilation.
