A:AnswerYou cannot plug this into a phone wall plug. A phone jack is RJ-11. An Ethernet jack or internet plug is an RJ-45. This is a usb hub and it needs plugged into a computer.
A:AnswerYes it will help with that but keep in mind this is not an adaptive fast charging port in itself so even if plugged into one, the speed will be split between any devices plugged in.
