Now this is a good idea--a replacement AC outlet cover that includes two USB ports. There have been some replacement duplex outlets around for a while, but they require a little more work, as you have to re-wire them into the outlet box. This RCA wall plate is simple--unscrew the existing wall plate, replace it with this one, and you are done. You have two USB ports and 1 AC port. I will note that the replacement outlet devices preserve both AC outlets.
