90W 20V AC Adapter for ThinkPad

This 90-watt AC adapter delivers 20 volts at 4.5 amps through a 7.9 by 5.5 millimetre three-prong round tip. It is built as a direct replacement for the original power supply on a wide range of Lenovo ThinkPad T, X, L and Edge series notebooks. The unit weighs about 0.75 pounds and ships with a detachable DC power cord.

100-240V Input with Safety Protections

The adapter accepts worldwide mains voltage from 100 to 240 volts at 50 or 60 hertz, so it works on any standard wall outlet without a voltage converter. Built-in over-current and over-voltage protection circuits guard the connected laptop against power anomalies. Output is fixed at 20 volts, so the charger cannot be used with devices that require a different voltage.

Black Housing with Round Three-Prong Tip

The black plastic enclosure houses the transformer and regulation circuitry while the 7.9 by 5.5 millimetre round tip with three prongs mates securely with the ThinkPad charging port. A detachable DC cord lets you replace a damaged cable without discarding the whole adapter. The connector geometry matches the listed FRU and part numbers, ensuring a firm fit on compatible models.

The brick supplies 20V at 4.5A, giving up to 90 watts of continuous DC power so the system can run and charge the battery simultaneously under full load.
