This adapter features built-in safety protections including Over Voltage Protection (OVP), Over Current Protection (OCP), and Short Circuit Protection (SCP) to safeguard your device.
3. Setup and Connection
- Verify Compatibility: Ensure your device is an AFNOP AceVac 11 cordless stick vacuum cleaner. This adapter is specifically designed for this model.
- Connect to Device: Insert the barrel connector of the adapter's output cable firmly into the charging port of your AFNOP AceVac 11 vacuum cleaner.
- Connect to Power Outlet: Plug the adapter's AC prongs into a standard 100-240VAC wall outlet.

The device should now begin to operate or charge its battery. Refer to your vacuum cleaner's manual for specific charging indicators.
4. Operating Instructions
Once connected, the adapter provides continuous power to your AFNOP AceVac 11 vacuum cleaner. If the vacuum's battery is depleted, the adapter will initiate the charging process.
- Charging: The adapter supplies 36V DC to charge the vacuum's 29.6V Li-ion battery. Note that the 29.6V refers to the vacuum's battery voltage, not the charger's output voltage.
- Battery Life: Rechargeable batteries have a finite lifespan, typically 1 to 3 years. If your vacuum's battery is old or faulty, it may not accept a charge, which is a battery issue, not an adapter malfunction.
- Continuous Use: The adapter can be used to power the vacuum directly while plugged in, or to charge the battery for cordless operation.
5. Maintenance and Care
To ensure the longevity and proper function of your Kircuit AC/DC Adapter, follow these simple maintenance guidelines:
- Cleaning: Disconnect the adapter from the power outlet and the device before cleaning. Wipe the adapter with a dry, soft cloth. 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 Inspection: Periodically inspect the power cord and connector for any signs of damage, such as fraying, cuts, or bent pins. If damage is observed, discontinue use and replace the adapter.
