This adapter/USB charger is of really good quality! It's compact and lightweight, perfect for travel, and compatible with many different devices. Plus I love the blue color! It has a universal plug for USA/Japan, Australia, Korea/Germany, and U.K. It has 4 USB ports and a blue LED light that indicates that it's operating properly. Once you push down the button for the proper country, the plug comes out, ready to be plugged into a socket. Overall great buy and I highly recommend.
