• AC/DC Wall Adapter: This unit converts household AC power to 5V DC power. It features a standard 2-pin plug for wall outlets and a USB-A output port.
• USB-A to USB-C Cable: This cable connects the wall adapter to your CARHEV JS-01 jump starter, which typically uses a USB-C input for charging.

4. Setup

Follow these steps to set up your Yustda AC/DC Adapter for charging:

1. Connect the Cable: Insert the USB-A end of the charging cable into the USB-A output port on the Yustda AC/DC wall adapter.
2. Connect to Jump Starter: Insert the USB-C end of the charging cable into the designated charging input port on your CARHEV JS-01 JS01 Car Battery Jump Starter.
3. Plug into Power Outlet: Plug the Yustda AC/DC wall adapter into a standard 100-240VAC 50/60Hz electrical wall outlet.

Ensure all connections are secure before proceeding.

5. Operating Instructions

Once properly connected, the adapter will begin supplying power to your CARHEV JS-01 jump starter. The jump starter's charging indicator (if available) should illuminate or change state to show it is receiving power.

• Allow the jump starter to charge fully according to its own instruction manual.
• Once charging is complete, disconnect the adapter from the wall outlet and then from the jump starter.

6. Maintenance

To ensure the longevity and proper functioning of your Yustda AC/DC Adapter, follow these maintenance guidelines:

• Keep the adapter and cable clean and dry. Avoid exposure to moisture or liquids.
• Store the adapter in a cool, dry place away from direct sunlight and extreme temperatures.
• Do not bend or crimp the cable excessively, as this can damage internal wires.
• Unplug the adapter from the wall outlet when not in use for extended periods.

7. Troubleshooting

If you encounter issues while using your Yustda AC/DC Adapter, consider the following:

• No Power/Charging:
  • Ensure the adapter is securely plugged into a working wall outlet.
  • Verify that the USB-A to USB-C cable is firmly connected to both the adapter and the jump starter.
  • Important Note: Rechargeable batteries do not last indefinitely. The average lifespan of a battery is 1 to 3 years. If the jump starter's internal battery is old or completely depleted (dead), it may not accept a charge, even with a functional charger. This indicates a battery issue, not a charger malfunction.
  • To confirm if the charger is working, a volt meter can be used to test its output.
• Overheating: If the adapter feels excessively hot, immediately unplug it from the wall outlet and disconnect it from the jump starter. Allow it to cool down. Ensure there is adequate ventilation around the adapter.
