90W USB-C charger for Dell laptops

This 90W USB-C power adapter supplies up to 20V at 4.5A and also delivers 85W at 11.8A for compatible Dell Latitude, XPS, Precision and Vostro models. It accepts 100-240V AC input at 1.8A for worldwide use.

Output profiles and headroom

The charger provides fixed profiles of 5V 3A, 9V 3A, 15V 3A, 20V 2.25A and 20V 4.5A, automatically negotiating the highest voltage the laptop supports. It covers 45W, 65W and 90W requirements, but cannot power devices that need more than 90W or a voltage above 20V.

Build integration and portability

A single USB-C cable handles both power and data negotiation, removing the need for a proprietary barrel connector. The compact casing fits easily in a laptop bag, and the corded design keeps the connector close to the device without an extra brick on the desk.
