90W AC Adapter for ThinkPad X1 Yoga and Y40

This 90-watt AC adapter replaces the original charger for Lenovo ThinkPad X1 Yoga and Y40 series laptops. It supplies 20 volts at 4.5 amps and accepts 100 to 240 volts input for worldwide use. The unit includes a six-foot two-prong AC cord for flexible placement. Buyers needing a higher-wattage supply for larger workstations should look elsewhere.

Plug-in replacement with built-in protections

Installation is a direct plug-in: connect the barrel tip to the laptop and the AC cord to a wall outlet. The adapter carries overload, short-circuit, over-voltage, over-current and over-temperature protection to guard the notebook. No drivers or configuration are required. Users with damaged DC jacks or non-standard tip sizes will find this unit incompatible.

90 watts for everyday workloads

The 90-watt output comfortably powers the CPU, integrated graphics, display and peripheral charging during typical office tasks and media playback. Under sustained heavy loads such as discrete GPU rendering or simultaneous fast charging of multiple USB-C devices, the adapter reaches its limit and may throttle. It is not intended for systems that draw more than 90 watts.
