• Protection features: short-circuit and overload protection (device-level protection common to notebook adapters)

How to use

Choose the DC voltage that matches the voltage requirement of your notebook or device before connecting. With the adapter unplugged from mains, set the output to the required voltage, then connect the DC output plug to the device and plug the adapter into an AC outlet. Use the integrated USB port to charge phones or other USB-powered accessories while the adapter supplies power to the notebook. Verify polarity and voltage compatibility with your device specifications to avoid damage.

Recommendations

Always confirm that your device accepts one of the selectable voltages and the connector fits securely. Do not use this adapter with devices that require voltages or connector types not listed. Avoid exposing the adapter to moisture, extreme temperatures or prolonged heavy load beyond the rated 45 W output. For reliable operation, ensure good ventilation around the adapter and periodically inspect the cable and connectors for wear.
