I was looking for a charger for my 2017 15" MacBook Pro. The Apple charger was too big to travel with. Although it has less power, it works and can charge you , if you do low intensity tasks on your computer. Of course, this can charge a computer overnight. One downside I don't see, you have to use the USB-C cable that comes with the charger. It looks like small capacitors have been built into the cable which has allowed the size of the charger itself to be reduced. It's about a meter or so. Too bad it was a bit longer. Overall the fit and finish is good. It's nice to have a smaller charger in your pocket to have. A really noticeable difference. I bought this instead of GAN chargers because nowadays they max out at around 45 W. In general I'm satisfied, I want d he cord is more authentic.
