  • UL safety certification ensures reliable charging

65W UL-Certified Laptop Charger

This 65-watt AC adapter replaces original power supplies for compatible Vivobook and Zenbook laptops. It delivers up to 19 volts at 3.42 amps and automatically supports lower 45-watt and 33-watt requirements. The unit carries UL safety certification, confirming it meets recognised electrical safety standards. It is designed for users needing a direct replacement charger with a round connector.

Check Connector Size Before Ordering

Verify that your laptop uses a round barrel connector and not a USB-C port measuring 6.0 by 3.7 millimetres or 7.4 by 5.0 millimetres, as this adapter is not suitable for those interfaces. Compare the tip dimensions against the supplied reference images to ensure a proper fit. Confirm your device operates within the 100 to 240 volt input range, which covers most global mains supplies. Buyers who need a USB-C power delivery charger cannot use this model.

Four Swappable Tips Included

The package provides four detachable round connectors that cover the 65-watt, 45-watt and 33-watt variants, letting you match the exact tip size your laptop requires. This eliminates the need to source separate tips for different power ratings within the same laptop family. A two-year manufacturer replacement warranty backs the adapter and included connectors. Users who require a fixed-tip cable or a single-tip configuration will not find that here.
