The power supply was required to have an output capacitive energy of less than 15.1 µJ and an inductive energy at disconnect of less than 5.3 µJ. [1] The standard defines an AC adapter to power devices requiring from 10 W to 130 W (~20 V × 6.5 A) or (extended voltage option) up to 240 W (60 V × 4 A). [2]
Apple offered an EmPower MagSafe power adapter for their MacBook, MacBook Pro, and MacBook Air lines of notebooks, and also included a cigarette lighter socket adapter.
