How to use

Confirm that your laptop requires 20V and does not exceed 8.5A draw, and that the 10×4 mm barrel connector matches the laptop’s DC jack. Connect the adapter to mains power using the supplied AC input cable, then insert the 10×4 mm barrel plug into the laptop power socket until it seats firmly. When charging is complete, unplug the adapter from the laptop, then disconnect mains power if not in use. Avoid forcing the connector or using adapters that modify the connector shape or polarity.

Usage recommendations

Use this adapter only with devices that match the specified voltage, current and connector size. Operate the adapter within ambient temperature limits, keep ventilation openings unobstructed, and avoid exposing the unit to moisture or prolonged direct sunlight. For prolonged heavy loads, ensure adequate cooling and periodically inspect the cable and connector for wear or damage.
