Have been using my computer for the past 2 weeks, and everything has been amazing. I use a 2nd charger when I'm on the go, and when I get home, I have a USB hub, external monitor, and another Apple 87w adapter plugged into a Apple Digital AV adapter as a sort of "single cable docking solution". I noticed today that my battery was at 75% (was at 100% before it was 'docked'). The icon indicated "plugged in, but not charging". Oddly enough, when I plug the 87w charger directly into the Mac, it charges just fine. The status reads "charging", and sure enough, the battery percentage goes up. I checked System Report, and noticed that when the 87w adapter is plugged in directly, it shows as "87 watts, charging". However, when it's plugged in via the Digital AV adapter, it reads "55 watts, not charging". Reset the SMC, issue persists. Issue reproducible with both Apple 87w adapters, and regardless of HDMI/USB ports on the adapter are plugged in. Looking to talk to Apple Support next, but I thought I'd throw this out there to see if anyone else is experiencing this issue... --- Post Merged, Feb 21, 2017 --- UPDATE: Apple support has provided me with an answer, and this is expected behavior: https://support.apple.com/en-us/HT207256 MacBook Pro can receive a maximum of 60W of power through the Apple USB-C VGA Multiport Adapter or USB-C Digital AV Multiport Adapter. For the best charging performance on MacBook Pro (15-inch, 2016), connect the power supply directly to your Mac. Guess that ruins my dream of a single-cable dock, but at least I know there is nothing wrong with my Macbook. Leaving this post for anyone who happens to search for the same issue.
