It doesn't, and it probably isn't (beyond being 5V/3A capable). It was cheap so I took a flyer on it. If it can charge the unit while in use, that's fast enough for me.

Competition instead of cooperation seems to have turned usb charging into a total cluster**** and I'm just not interested enough to delve into it. I will settle for something that gets the job done in reasonable time and doesn't feel like it might catch fire on the way

Edit : Also noted from your stockmind link that usb-c data isn't currently working, so maybe all is not lost for the lan adapter
