45W USB-C Adapter for Acer Chromebooks

This 45W USB-C AC adapter replaces the original charger for Acer Chromebook Spin 11 311 315 CP311 C771 C732 models. It also supports a wide range of Acer Chromebook series including 311 314 315 511 713 C721 C732 C733 C771 C851 C933 CB311 CB314 CB315 CB514 CB515 CB713 CB714 CB715 CB5-312 CB5-312T CP5-471 CP311 CP511 CP713 R721 R751 R752T R851. The package includes the power adapter and a detachable power cord.

Thermals noise and power draw in daily use

The adapter accepts 100-240V input at 1.3A 50-60Hz for worldwide voltage compatibility. It delivers a maximum output of 45W at 20V 2.25A with additional fixed voltage steps at 5V 3A 9V 3A 12V 3A 15V 3A and 18V 2.5A. The compact brick runs silently with no moving parts and stays cool during typical charging sessions.

Upgrading from a lost or lower-wattage charger

This unit replaces a missing or damaged 45W USB-C charger and restores full charging speed for compatible Chromebooks. The jump is worth it when the original adapter is lost or when a lower-wattage USB-C charger cannot sustain 45W output. It is not for devices that require a barrel connector or proprietary charging port.

Questions about this item

How do I install the USB-C adapter and what step do people often miss?

Connect the power cord to the adapter, plug into a 100-240V 50-60Hz outlet, then insert the USB-C connector into the Chromebook; the step often missed is confirming the laptop draws 20V 2.25A rather than a lower voltage.

What maintenance or replacement will this adapter need later?

The detachable power cord can wear at the strain relief; replace it with any standard IEC C7 figure-8 cord if the insulation frays or the plug loosens.

What limit appears first under sustained full-load use?

The 45W maximum output caps sustained power; if the Chromebook requests more than 20V 2.25A the adapter will not supply it and charging slows.
