Review on 65W AC Adapter Charger for Acer C720 C720p C740 Aspire P3 P3-131 R14 R5-471T S7 S7-191 S7-391 S7-392 Chromebook 15 14 13 11 R11 CB3 CB5 CB5-571 - Cord Wall Ac Adapter by Frank Chinchilla

Update: Yes, the mouse pad does not work when charging. It also gets a lot hotter than the charger that came with my C720P Chromebook. I've been using it for 2.5 months now. I just turn it on when I'm around and leave it off when I'm leaving. I just quickly pull it out to perform certain mouse pad movements and then plug it back in. The alternative, which might not have been better, cost three times as much. So now I'm happy.
