It depends on the airlines, but most Asian ones do have outlets. They're usually located at the base of the armrests. You may have to share, as it is usually a 2 outlets / 3 seats.

That said, The exit seats might not necessarily be "worth it" for you. For example, to me, the thicker than normal armrests are a bad thing for me. While I can fit into the seat, the inability to stretch sideways a bit is not good. Also since you're in the exit row, it'll often be colder than further in the cabin. Just having a plug at the seat might not be enough for you.
