How to use

Connect the adapter to an appropriate AC mains outlet using the supplied or compatible region-specific power cord or plug. Insert the USB-C plug into the USB-C power port of the laptop or device. The adapter and the connected device will negotiate the required voltage and current via USB Power Delivery; charging will begin automatically once negotiation completes. Disconnect the adapter from the device and then from the mains when charging is finished or when transporting the adapter. Avoid using the adapter with devices that require higher than 45W unless the device supports negotiated lower-power charging.

Recommendations

Use the adapter with cables and devices that support USB-C Power Delivery. For optimal performance, use the original or certified USB-C cable rated for power delivery. Avoid exposure to extreme temperatures, liquids, and prolonged direct sunlight. If the adapter becomes unusually hot or emits odors or smoke, disconnect it immediately and stop use. Ensure the mains supply matches regional specifications and use a suitable plug or power cord where required.
