I have two of these adapters, one for home and one for my work bag. They work great, even with my 35-inch 3440 x 1440 monitor at home, and pass-through charging works with my personal 12-inch MacBook, which only has a USB-C port. One of them recently stopped working, more than a year after I ordered it. When I reported the blinking, Anker immediately sent a working, used replacement unit with an 18 month warranty. I was very happy that they could replace it for free: Anker's support is the best!
