Power adapter
Power adapters are used to supply power to portable computers, tablets, and certain desktop computers. The Dell power-adapter kit
consists of the power adapter and the power cable. The power‑adapter rating (90 W, 65 W, and so on) depends on the device 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 shipped with your device or a
Dell‑approved replacement power adapter.
