2. Setup

1. Unpack the Adapter: Carefully remove the Kircuit USB-C 5V AC/DC Adapter from its packaging.
2. Connect to Power Outlet: Plug the AC adapter into a standard wall power outlet (100-240VAC, 50/60Hz). Ensure the outlet is functioning correctly.
3. Connect to Device: Insert the USB-C connector of the adapter into the designated USB-C charging port on your CAT Cube PPSCL3 1750A Jump Starter.
4. Verify Connection: Ensure both connections are secure. The device should indicate that it is receiving power or charging (e.g., via an indicator light).

3. Operating

Once connected, the adapter will begin to supply power to your device or charge its internal battery. The charging process is automatic.

• Charging Indication: Refer to your CAT Cube Jump Starter's manual for specific charging indicators (e.g., LED lights, display messages).
• Important Note on Voltage: The 11.1V specification often associated with jump starters refers to the jump starter's internal battery voltage, NOT the charger's output voltage. This Kircuit adapter provides 5V DC output, which is the correct input for the USB-C charging port of compatible devices.
• Battery Lifespan: Rechargeable batteries have a finite lifespan, typically 1 to 3 years. An old or dead battery may not accept a charge, which is a battery issue, not a charger malfunction.

4. Maintenance

• Storage: Store the adapter in a cool, dry place when not in use.
• Cleaning: Use a soft, dry cloth to clean the adapter. Do not use liquid cleaners or solvents.
• Avoid Damage: Do not bend or crimp the cable excessively. Avoid exposing the adapter to extreme temperatures or moisture.
• Unplug When Not in Use: For safety and energy conservation, unplug the adapter from the wall outlet when it is not actively charging a device.

5. Troubleshooting

• Device Not Charging:
  • Ensure the adapter is securely plugged into both the wall outlet and the device.
  • Test the wall outlet with another device to confirm it is supplying power.
  • Inspect the USB-C port on your device and the adapter's connector for any visible damage or debris.
  • If the device's battery is old or completely depleted, it might not accept a charge. A voltmeter can be used to verify if the charger is outputting power correctly.
• Adapter Overheating:
  • It is normal for the adapter to feel slightly warm during operation. If it becomes excessively hot, unplug it immediately.
  • Ensure the adapter is used in a well-ventilated area and not covered.
