AC Adapter
AC adapters are used to supply power to portable computers and certain desktop computers. AC adapters convert AC current to DC current for supplying to
computers. The Dell AC-adapter kit consists of the AC adapter and the power cable. The AC-adapter power rating (65 W, 90 W, and so on) depends on the
computer it is designed for, and the power cable varies based on the country where the AC adapter is shipped.
CAUTION: It is recommended to use only the AC adapter that shipped with your computer or a Dell-approved replacement AC adapter,
to avoid damaging your computer.
