Identify the required plug type for your destination (e.g., EU, UK, USA/AUS).
Locate the corresponding slider on the side of the adapter.
Slide the button forward until the pins fully extend and lock into place.
To retract, press the release button (if present) and slide the pins back into the adapter body.

5.2. Connecting Devices

Once the correct plug type is extended, insert the adapter into a wall socket. The adapter is now ready to charge your devices.

AC Outlet: Plug your device's power cord into the universal AC outlet on the front of the adapter. Ensure the device's voltage is compatible with the local power supply.
USB-A Ports: Connect your USB-A compatible devices (e.g., older smartphones, smartwatches) using their respective USB-A cables.
USB-C Ports: Connect your USB-C compatible devices (e.g., modern smartphones, tablets, laptops) using their respective USB-C cables. The USB-C4 port supports Power Delivery (PD) for faster charging of compatible devices up to 65W.

6. Maintenance

6.1. Fuse Replacement

The adapter is equipped with double fuses (10A) for safety. If the adapter stops working, the fuse may have blown due to an overload. A spare fuse is included with your adapter.

Unplug the adapter from the wall socket and disconnect all devices.
Locate the fuse compartment, usually on the side or bottom of the adapter.
Open the fuse compartment (you might need a small flat-head screwdriver or coin).
Carefully remove the blown fuse and replace it with the spare 10A fuse.
Close the fuse compartment securely.
Plug the adapter back into the wall and test its functionality.

6.2. Cleaning

To clean the adapter, ensure it is unplugged from all power sources and devices. Use a dry, soft cloth to wipe the surface. Do not use liquid cleaners or abrasive materials.

7. Troubleshooting

Adapter not powering on: Check if the adapter is securely plugged into the wall socket. Verify the wall socket is active. Check and replace the fuse if necessary (refer to Section 6.1).
Device not charging: Ensure your device is properly connected to the correct USB port or AC outlet. Check if your charging cable is functional. Verify that your device is compatible with the adapter's output specifications.
Slow charging: Ensure you are using the appropriate USB-C port (USB-C4 for PD fast charging) and a compatible cable for fast charging. If multiple devices are connected, the total output power is shared, which may reduce individual charging speeds.
Overheating: It is normal for the adapter to get slightly warm during operation. If it becomes excessively hot, unplug it immediately and allow it to cool down. Ensure proper ventilation and avoid covering the adapter. Do not exceed the maximum rated power (2500W).

8. User Tips

Check Voltage: Always double-check the voltage requirements of your appliances and the local power supply before plugging in, especially for high-power devices.
Optimal Charging: For the fastest charging of laptops or high-power devices, use the dedicated 65W USB-C PD port (USB-C4) with a compatible cable.
Compact Travel: The all-in-one design eliminates the need for multiple adapters, saving space in your luggage.
