This is a really handy plug-in invention for travelerers and even for home use. I like the size of it. It is easy to pack in a bag or carry on. It is big enough so that I won't lose in a drawer. It is really ingeneous. It has slide out plugs for the Eu, the USA/Australia, and the UK. Then in the back it has a plug in for the US, and other countries. So you can take your hair dryer with you. Then it has the USB ports, both A and C. I bought it for the USB ports and have already used it for charging and it works very well. Eventually you will have to replace a fuse but it is fine right now. It would make a great gift for travelers you know also.
