I have a new MacbookPro with only USB-C ports. Does there exist a wall charger for USB-C that can provide the appropriate power while also providing a sort of built in dongle for USB and an SD card reader? I am looking for something like the below image, where the extra USB ports also provide data to my mac when plugged in via USB-C. Does such a product exist? I would never need to remember to bring another dongle again, just bring my wall charger.
