How to use

Connect the adapter to an appropriate AC mains outlet using the supplied or compatible mains cable, then plug a USB-C cable into the adapter's USB-C output and into the device's USB-C power input. The adapter will negotiate power delivery with the connected device and supply up to 65W as supported by the device. Ensure the USB-C cable used is rated for the required power level to enable full charging performance.

Recommendations
