It IS a case of using a wall wart to provide enough power to run the Dot 3rd gen. Not even linking two USB ports could you obtain that level of power. Amazon had to use a wall wart.

I know and I guessed it was likely for the speakers. Again, it's just inconvenient. Even the charging tip is fairly standard. It's just not ubiquitous like USB is. Kinda wish Amazon had gone the USB-C PD route.
