This is a genuine Lenovo 90W AC adapter (model ADLX90NLC3A, identical to ADP-90XD B) in fully working condition. It outputs 20V at 4.5A and uses the rectangular yellow slim-tip connector plug. This original OEM charger is compatible with a wide range of modern Lenovo hardware, including ThinkPad (T, L, X, E series) laptops, IdeaPad models, Yoga configurations, and ThinkCentre Tiny PCs. It accepts global input voltage (100–240V) but will not fit older models with round barrel charging ports
