Replacement AC adapter for Acer Chromebook

This 65 W AC adapter supplies 19 V at 3.42 A and accepts 100-240 V input at 50/60 Hz. It uses a 3.0 mm by 1.1 mm barrel connector that matches the original charger for listed Acer Chromebook models. The package includes the adapter and a mains power cable.

Installation check and common issues

Verify that your old charger has the same 3.0 mm by 1.1 mm tip before ordering; the connector is not USB-C. A loose fit or reversed polarity will prevent charging, so compare the plug visually with the product image. No drivers or software are required — simply plug the adapter into the laptop and the cable into a wall socket.

Who this suits and who should look elsewhere

Suitable for owners of compatible Acer Chromebook C720, C720P, C730, C731, C732, C738T, C740 and CB3, CB5 series laptops needing a direct replacement. Buyers whose devices use USB-C charging or a different barrel size cannot use this adapter.
