GCROWN 45W USB-C Adapter for Lenovo Chromebook

This GCROWN 45W USB-C AC adapter supplies power to Lenovo Chromebook series laptops. It accepts 100-240V 50-60Hz input for worldwide use. The unit is UL Listed, confirming it meets recognised electrical safety standards. It is intended for owners who need a replacement or spare charger.

USB-C Power Delivery 45W output limits

The adapter delivers 45 Watts through USB-C Power Delivery with fixed output profiles of 5V-3A, 9V-3A, 15V-3A and 20V-2.25A. It cannot supply voltages or currents outside these four steps. Devices requiring more than 45 Watts will not charge at full speed. The single port charges one laptop at a time.

Simple plug-in installation and common issues

Installation requires only connecting the USB-C plug to the laptop and the mains lead to a wall socket. No drivers or configuration are needed. The most frequent problem is using a cable that does not support the required Power Delivery profile, which prevents fast charging. A damaged or loose port on the laptop can also stop the charger from working.

Questions about this item

Which voltage step should I expect this 45 W adapter to use with my Chromebook?

The adapter negotiates 5 V 3 A, 9 V 3 A, 15 V 3 A or 20 V 2.25 A via Power Delivery; your Chromebook will draw the highest voltage it supports up to 45 W.

What does the 45 W rating mean when the charger is plugged into my Lenovo Chromebook?

It is the maximum power the brick can deliver; actual draw depends on the Chromebook’s charge state and PD negotiation, so you may see less than 45 W once the battery nears full.

Does the USB-C connector on this adapter support the full USB Power Delivery specification?

Yes, it implements PD with the four fixed voltage steps listed — 5 V, 9 V, 15 V and 20 V — enabling fast charging on compatible Lenovo Chromebooks.
