What it is and who it's for

A 45W USB-C power adapter built for Chromebooks and laptops that charge through USB Power Delivery. It suits students, mobile professionals and IT teams replacing a lost or damaged original charger.

The spec that decides fit

Output reaches 45W through 20V at 2.25A with additional PD steps at 5V, 9V, 12V, 15V and 18V. The unit only works with devices that accept USB-C PD charging; laptops needing barrel connectors or higher wattage cannot use it.

Installation and common issues

Plug the detachable AC cord into the brick, connect the USB-C cable to the laptop and power begins — no drivers required. The reinforced joint survives over 10,000 bends, yet the fixed cable means a damaged wire still replaces the whole adapter.
