This 65 W AC adapter delivers selectable USB-C output voltages from 5 V to 20 V at up to 3.25 A. It is designed as a direct replacement for the listed OEM part numbers across HP EliteBook and Lenovo ThinkPad, ThinkCentre, IdeaPad and Chromebook models.

Check your device and connector before ordering

Verify that your laptop or desktop accepts USB-C charging and matches one of the compatible part numbers such as 4X20M26268 or ADLX65YCC2A. The unit operates on 120 V or 230 V AC mains input, so confirm your local outlet type and cable.

Thermal and acoustic profile

The adapter runs passively with no internal fan, so it produces no audible noise during normal use. Heat is dissipated through the enclosure; keep ventilation slots clear and avoid covering the brick while it supplies the full 65 W load.
