A:Answer Hi, MrsO,
Thank you for reaching out.
Your Acer Chromebook 11 CB3-111 seems to use a DC jack in (barrel) for its power port. The 65W Chromebook Power Adapter is a USB-C power adapter with two tips for barrel power ports. To understand if one of these tips is compatible with your laptop, contact us at support at einova dot com and we'll gladly help. -
