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.
