Replacement 65 W USB-C adapter

This 65 W USB-C AC adapter replaces the original charger for a wide range of Dell Latitude, Inspiron, XPS and Chromebook models. It delivers up to 65 W and is backward-compatible with devices that require 45 W. The unit accepts 100 V to 240 V input at 50 Hz or 60 Hz, making it suitable for travel. A USB Type-C connector provides the physical link to the laptop.

Power delivery limits of USB-C PD

The adapter negotiates five fixed voltage steps: 5 V at 3 A, 9 V at 3 A, 12 V at 3 A, 15 V at 3 A and 20 V at 3.25 A. Maximum output is capped at 65 W, so systems that demand more than 65 W will not charge at full speed. The 1.8 A input rating at the mains side sets the upper bound for AC current draw. No higher voltage or current profiles are supported.

Upgrade from lower-wattage or barrel-tip chargers

This unit replaces older 45 W USB-C chargers and legacy barrel-tip power supplies on compatible Dell laptops. The jump is worth it when the original adapter is lost, damaged or limited to 45 W while the laptop can accept 65 W for faster charging. It is not for users who need more than 65 W, multiple simultaneous outputs or a different connector type.
