Ideal for Lenovo IdeaCentre AIO owners

This 90 W AC adapter delivers 20 V at 4.5 A through an 11x5 mm barrel plug. It replaces the original ADP-90XD B or ADLX90NLT3A charger for compatible all-in-one desktops. The unit ships new with a detachable power cord included.

Check your device label before ordering

Verify that the original power supply lists 20 V output and 4.5 A current with the same 11x5 mm connector. Confirm the part number matches ADP-90XD B or ADLX90NLT3A exactly. Ensure your mains supply falls within the 100-240 V 50-60 Hz input range.

Runs cool and quiet in daily use

The adapter operates on standard 100-240 V 50-60 Hz mains without a fan, so it remains silent during normal operation. Rated at 90 W, it draws only the power required by the connected AIO. CE certification confirms compliance with European safety standards.
