The Innergie PowerJoy 30C, unveiled at Computex 2017, is Innergie's first USB-C wall charger, retailing for US$44. It features SmartBoost for up to 35% faster charging and InnerShield power protection, and ships with three interchangeable travel plugs.
The Apple USB-C Digital AV Multiport Adapter retails for S$98. It extends a single USB-C port into three: HDMI, USB-A, and USB-C. The HDMI supports full HD at 60Hz or 4K at 30Hz, though Apple notes some incompatibilities.
I found an unopened Apple Mini DisplayPort to VGA Adapter in my drawer and decided to write it up. It retails for S$38, a price unchanged after all these years; the Mini DisplayPort to DVI Adapter costs the same.
