45W USB-C Power Adapter

This 45W USB-C AC adapter delivers up to 45 watts through a Type-C connector. It accepts a 100-240V AC input at 1.3A and provides selectable output voltages of 5V, 9V, 15V and 20V. The unit includes over-charge, over-voltage, over-temperature, over-current, short-circuit and lightning protection with CE, FCC and ROHS certificates.

Suits owners of listed Acer models

Buyers with an Acer Chromebook R721T, R752T, R752TN, CB5-312T or Switch Alpha 12 SA5-271P can use this adapter as a spare or replacement. It also matches the N17Q8, N18Q5, PA-1450-78 and other part numbers shown in the compatibility list. Users whose devices require a barrel connector, a higher wattage supply or a proprietary non-USB-C charging port should look at a different adapter.

Check your device before ordering

Verify that your laptop charges via USB-C and that its original charger is rated at 45W with 20V 2.25A output. Confirm the exact model number appears in the supported list, including Chromebook Spin 11, 13, 14, 15, 311, 314, 511, 512, CP311, CP315, CP511, CP713, CB311, CB314, CB315, CB514, CB515, CB713, CB714, CB715, CP5-471, C721, C732, C733, C771, C851 or C933 series.

Questions about this item

Does the adapter need a separate IEC C7 mains lead, or is the AC cable built in?

The unit ships with a fixed AC cable that plugs directly into a 100-240 V wall socket, so no extra mains lead is required.

Will it safely charge an older Acer model that only accepts 5 V or 9 V over USB-C?

Yes — the charger negotiates 5 V at 3 A, 9 V at 3 A, 15 V at 3 A or 20 V at 2.25 A, so legacy devices drawing 5 V or 9 V are supported.

How can I confirm the adapter is delivering the correct 45 W to my Chromebook?

The Chromebook's battery indicator will show charging at full speed and the OS power menu will report a 45 W USB-C source when the adapter is connected.
