4. Setup
- Inspect: Before connecting, visually inspect the adapter and its cable for any signs of damage.
- Connect to Device: Plug the USB-C connector of the Onerbl adapter into the designated USB-C charging port on your CAT Cube PPSCL3 1750A Jump Starter Power Station.
- Connect to Power Outlet: Insert the AC plug of the adapter into a standard 120V AC wall outlet.
5. Operating Instructions
Once connected, the Onerbl AC-DC Adapter will begin supplying power to your device. If connected to a rechargeable device like the CAT Cube Jump Starter, it will initiate the charging process.
- Charging Indication: Refer to your device's user manual for specific charging indicators (e.g., LED lights, screen display) to confirm that it is receiving power and charging correctly.
- Charging Time: Charging times will vary depending on the device's battery capacity and current charge level.
- Disconnecting: To disconnect, first unplug the adapter from the wall outlet, then disconnect the USB-C cable from your device.
6. Maintenance
- Cleaning: Clean 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.
- Inspection: Periodically inspect the adapter and cable for any signs of wear or damage.
7. Troubleshooting
- Device Not Charging:
- 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 appliance.
- Important Note: If your device's rechargeable battery is old or dead (typically lasting 1 to 3 years), it may no longer accept a charge. This is a battery issue, not an adapter malfunction. A voltmeter can be used to confirm if the adapter is outputting power.
- Adapter Overheating: Disconnect the adapter immediately. Ensure it is used in a well-ventilated area and not covered. If overheating persists, discontinue use.
