Universal 65W 45W 33W Laptop Charger

This universal AC adapter replaces lost or damaged power supplies for compatible VivoBook, ZenBook and Chromebook notebooks. It delivers up to 65W at 19V 3.42A and automatically steps down to 45W or 33W for lower-rated models. The unit includes interchangeable tips covering four common barrel sizes. It suits students and professionals needing a single spare charger for multiple supported laptops.

Connector Compatibility Check

Before ordering, verify that your laptop uses one of the supplied tip sizes: 3.0 x 1.1 mm, 4.0 x 1.35 mm, 4.5 x 3.0 mm or 5.5 x 2.5 mm. Confirm the device requires 19V DC input and that its original adapter is rated at 33W, 45W or 65W. Cross-reference your exact model number against the supported series list to ensure the correct fit. Polarity and voltage must match the original specification.

Thermals Noise and Power Draw

The adapter operates silently with no moving parts and runs warm during normal charging at 65W output. Heat dissipates through the plastic enclosure without active cooling. It draws only the power required by the connected laptop up to the 65W maximum. Efficiency meets standard levels for universal laptop power supplies of this class.
