90W 4.5mm AC Adapter

The Dell 450-AKVN 90W AC adapter powers laptops with a 4.5 mm barrel connector. It is intended for indoor use with a laptop equipped for this connector; the rating and connector identify this variant.

The black adapter has a 2 m cable, allowing it to be placed between an indoor outlet and the laptop within the cable’s reach. The package contains one adapter.

It can serve as a second power adapter for a laptop setup. Keeping one at home and another in the office avoids moving the same adapter between those locations. The distributor also describes keeping it for travel. Its role is to provide an additional indoor power source for a compatible laptop, with the 90W rating and 4.5 mm connection defining the model.
