65W AC adapter for Chromebooks

This 65W AC adapter delivers 19V at 3.42A through a 3.0mm barrel connector. It is built for Chromebook models across the 11, 13, 14 and 15 series including CB3, CB5, C720 and C720P families. The unit accepts 100-240V input at 50-60Hz for worldwide use. It ships with an AC power cord included.

Replaces original chargers like A11-065N1A

The adapter matches part numbers such as N15Q8, N15Q9, N16P1 and ADP-45HE B used on many Chromebook 15 CB3-531, CB3-532 and CB5-571 models. It also covers Chromebook 14 CB3-431 units and Chromebook 11 R11 CB3-111, CB3-131 systems. The jump is worth it when the original brick is lost, damaged or no longer holds a stable charge.

Steady 65W output under continuous load

The power supply maintains its rated 65W during extended charging sessions rather than throttling after a short burst. The 100-240V input handles voltage fluctuations without dropping the DC rail. Connector fit stays secure on the 3.0mm jack through repeated insertions. The brick runs within normal thermal limits while powering the laptop and charging the battery simultaneously.
