A:AnswerThis tv plugs into a standard 110v plug. This would be any standard plug in your home.

A:AnswerThere are apps on the apple app store that allow you to do this. But it doesn't work the best, if you want to use iphone with this tv id recommend apple tv. They are 50$ and are sure to work better than the apps you'll find such as imediashare which is kind of slow.
