How to use

Attach the appropriate plug insert for the destination socket (EU, UK or US) until it locks into place. Connect the permanently attached USB-C cable to the device to be charged and plug the adapter into a compatible mains socket (110–240 V AC). The charger negotiates the required voltage and current via Power Delivery or PPS where supported. Disconnect the charger by first unplugging from the mains and then detaching the device cable when charging is complete. Allow the unit to cool if it has been used under heavy load before storing.

Usage recommendations

Use only approved USB-C cables and ensure the device supports the required PD or PPS profiles for optimal charging. Do not cover the adapter during extended high-load operation and keep it away from liquids and extreme temperatures. For travel, verify local mains voltage and socket type before connecting and securely attach the correct plug insert.
