I was looking for a USB-C Ethernet adapter and came across the Belkin USB-C to Gigabit Ethernet Adapter which retails for S$49 in Apple Stores and Anker USB-C Aluminum Portable Gigabit Ethernet Port Network Adapter which retails for US$22.99 (S$32) on Amazon.
I find that the Belkin Ethernet adapter is overpriced and if you want to get the Anker Ethernet adapter, you might as well top up a little more to get the Anker USB-C to 3-Port USB 3.0 Hub with Ethernet Adapter.
If you are looking to use a USB-C to USB-Cable to charge your USB-C MacBook Pro, your USB-C power adapter and USB-C cable need to support USB Power Delivery.
The Anker PowerLine USB-C to USB-C Cable is retailing for US$15.99 (S$23) and is available in 3ft (0.9m).
It is tough to find a USB-C to DisplayPort Cable or USB-C to DisplayPort Adapter. I have not found any physical stores in Singapore selling it yet. Instead, you have to get it from online stores like Lazada or Amazon.
For USB-C to DisplayPort cable, I bought mine from Amazon as there are more choices to choose from.
I was looking for a USB-C micro/SD card reader and chanced upon SanDisk Extreme Pro SD UHS-II Card USB-C Reader on the Apple Store and it retails for S$75.
It is very expensive and can only read SD card.
