USB Type-C ports have become fairly common, with Google adopting them on their Pixel and Nexus computers and phones and Apple implementing them on the 12″ MacBook and now the new MacBook Pro. Shoppers have to be very careful to buy exactly the right cable for their devices! With Apple, Google, and many other companies jumping on USB Type-C and Thunderbolt 3, the world of connectivity just got very weird USB Type-C: Ports vs. See, that simple-looking port hides a world of complexity, and the (thankful) backward-compatibility uses different kinds of cables for different tasks.

Did you buy the new MacBook or MacBook Pro? Maybe the Google Pixel? You’re about to enter a world of confusion thanks to those new “USB-C” ports.
