45W USB-C Charger for Chromebooks

This 45W USB-C power supply delivers 100-240V AC input at 1.3A and multiple DC output profiles from 5V to 20V. It is built for owners of compatible HP, Acer and Lenovo Chromebook models who need a replacement or spare adapter. The unit is supplied new and carries CE certification.

Output profiles and headroom

The charger negotiates 5V at 3A, 9V at 3A, 12V at 3A, 15V at 3A, 18V at 2.5A and 20V at 2.25A. It comfortably handles devices that draw up to 45W at 20V. Systems requiring higher voltage or current beyond these fixed steps will not charge at full speed.

USB-C Power Delivery limits

The adapter uses the USB-C connector with Power Delivery negotiation across six fixed voltage steps. It does not support programmable power supply (PPS) or adjustable voltage beyond the listed profiles. Cables must be rated for at least 3A at 20V to deliver the maximum 45W; thinner cables will limit charging current.

Questions about this item

Will this 45W USB-C charger work with my older Acer Chromebook CB311-1H that originally used a barrel connector?

This charger only supplies power through its USB-C output, so it cannot connect to the barrel port on your CB311-1H.

How can I verify the charger is delivering the correct 20V 2.25A profile to my Lenovo 500e after plugging it in?

The unit has no display; confirm the negotiated voltage on the laptop's battery settings or with a USB-C power meter.

Does the box include a detachable AC cable or must I buy a C5 lead separately?

The power cord is permanently attached to the adapter, so no separate AC lead is required.
