Review on AC Power Adapter Charger for Acer Chromebook 15 14 13 11 R11 CB3 Series CB3-111 CB3-532-C47C CB3-431 CB3-431-C5FM CB3-131 CB3-111-C8UB CB3-131-C3SZ CB3-532 AO1-131, AO1-431 Laptop Power Supply by Mike Kimball

Bought this to have a charger at home and at work. The I/O specs match the OEM charger, but I will not charge my laptop unattended as the transformer gets too hot to touch. TO UPDATE. After 60 days, this device failed. I contacted the supplier through Revain late Friday evening and they responded almost immediately. After answering a few questions they said they would send me a new one. I received it mid next week and it works great. does not heat like the first. I have to say that the customer service I received far exceeded my expectations.
