About Your Computer Power Adapter Power adapters are used to supply power to portable computers and certain desktop computers. The Dell power-adapter kit consists of the power adapter and the power cable. The power‑adapter 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 power adapter is shipped. CAUTION: To avoid damaging your computer, it is recommended to use only the power adapter that shipped with your computer or a Dell‑approved replacement power adapter. 16  Power Adapter
