How to use

Connect the adapter to the mains supply using a suitable local mains lead or plug, then attach a USB‑C cable between the adapter and the device’s USB‑C power input. Ensure the connected device supports USB‑C power delivery and that its power requirement does not exceed 45W. Charging will begin automatically when the cable is connected and the mains supply is active. Disconnect the adapter by removing the USB‑C cable and then unplugging the mains lead when charging is complete or when the adapter is not in use.

Recommendations

Use a high-quality USB‑C cable rated for power delivery, avoid using the adapter in damp or excessively hot environments, and store it in a dry place when not in use. If a device requires more than 45W, use a higher-wattage adapter designed for that device to ensure proper charging and performance.
