Very handy multifunctional USB Wall plug. It has 2 AC outlet plugs, as well as 2 USB charging ports, and serves as a surge-protector as well. It quickly, conveniently turns one outlet socket into 4 sockets.
I'm very happy with mind because it gives me 3 extra outlets. It's perfect to use anywhere - at home, work, etc. I highly recommend this mountable wall plug because it is convenient as well as very safe.
