Onerbl AC-DC Adapter Instruction Manual

1. Introduction

This manual provides essential information for the safe and effective use of your Onerbl AC-DC power adapter. This adapter is designed to convert standard AC electrical power into the DC power required by compatible devices, specifically the Olubfdh JY-LB2201 and JYLB2201 21V Lithium-Ion battery-powered electric cordless leaf blowers. Please read these instructions carefully before use.

2. Product Overview

3. Compatibility

This AC-DC adapter is specifically designed for use with:

• Olubfdh JY-LB2201 Electric Cordless Leaf Blower
• Olubfdh JYLB2201 Electric Cordless Leaf Blower
• Devices requiring a 21V DC input and compatible barrel connector, typically for 4.0Ah Lithium-Ion (Li-ion) batteries.

Important Note:

The 21V specification refers to the leaf blower's battery voltage, not the charger's output voltage. This adapter is engineered to provide the correct charging voltage for 21V battery systems.

4. Setup

Follow these steps to set up your Onerbl AC-DC adapter:

1. Inspect the Adapter: Before each use, visually inspect the adapter, cable, and connector for any signs of damage, fraying, or exposed wires. Do not use if damaged.
2. Connect to Device: Insert the barrel connector of the adapter firmly into the charging port of your Olubfdh leaf blower's battery or the leaf blower itself, if it has an integrated charging port. Ensure a secure connection.
3. Connect to Power Outlet: Plug the AC adapter into a standard 110-240V AC electrical wall outlet.
4. Verify Charging: Observe the charging indicator on your leaf blower or battery (if available) to confirm that charging has begun.

5. Operating Instructions

Once connected, the adapter will supply power to operate your device or charge its battery. For optimal battery life, it is recommended to fully charge the battery before initial use and to avoid completely draining the battery frequently.

Important Note on Batteries:

Rechargeable batteries have a finite lifespan, typically 1 to 3 years depending on usage and care. If an older battery does not accept a charge, it may indicate the battery has reached the end of its service life, not a fault with the charger.

6. Maintenance

To ensure the longevity and proper function of your adapter:

• Cleaning: Disconnect the adapter from the power outlet and device before cleaning. Use a dry, soft cloth to wipe the exterior. Do not use liquid cleaners or immerse the adapter in water.
• Storage: Store the adapter in a cool, dry place away from direct sunlight and extreme temperatures. Avoid wrapping the cable too tightly around the adapter to prevent damage.
• Handling: Do not pull the cable to disconnect from the outlet or device. Always grasp the plug or connector directly.

7. Troubleshooting

If you encounter issues with your adapter, refer to the following common problems and solutions:

• Device Not Charging/Powering On:
  • Ensure the adapter is securely plugged into both the wall outlet and the device.
  • Verify the wall outlet is functional by testing it with another device.
  • Check the adapter cable and connector for any visible damage.
  • If using an older battery, consider that the battery itself may be at the end of its lifespan.
• Adapter Feels Warm:
  • It is normal for the adapter to feel slightly warm during operation. If it becomes excessively hot, disconnect it immediately and contact support.
