The 12-inch MacBook is the first Apple product with new USB Type-C port. USB Type-C or USB-C port is getting ubiquitous especially in Android smartphones and non-Apple gadgets. It is build to replace the standard USB-A and USB-B. Be careful when you buy a USB-C cable as Google engineer Benson Leung has managed to get one cable that fried his $1.5k Chromebook computer.
USB Type-C manufacturers are making cables so poor that Amazon has banned USB-C cables that are not compliant with standard specifications. That’s some peace of mind but you might want to opt for Apple’s USB-C 2m Charge Cable if you don’t mind paying for the premium. To connect your Macbook’s USB-C port to standard USB device such as thumb drive, Apple has you covered with its USB-C to USB Adapter. If you’re buying a power adaptor for your MacBook, it is recommended that you buy the Apple made 29W USB-C Power Adapter.
