In all seriousness though, these are important for a non-obvious reason: Nexus 6x devices don't ship with USB2-USB3 adapters (they only have a USB3 cable with a wall charger).
So ... anyone who wants to hook up their Nexus 6x to a laptop will almost certainly to Amazon to buy a cable. This is what I did last week, and just today I discovered that certain cables do not quick charge.
Benson Leung, you are doing the lord's work. May future Nexus 6x owners benefit from your expertise.
