I purchased this travel adapter for our upcoming trip to UK. Seriously, I had many different types of power adapters and I have to say that this is the most brilliant one. Period! It has 4 USB ports and one universal AC sockets to charge all my devices. So compact, the US, UK, EU and AUST plugs are all in one built. Much lighter than expected so that it can stay on wall with no problem. Bright blue color, so easy to find in rooms or suitcase and never leave it in hotels when check out. Great price, solid quality, highly recommended! Please be aware- this is not a converter! It can’t convert voltages from 110V to 220V, or 220V to 110V. No hair dryer, curler, straightener, or steam iron can be used with it. But the small dual voltage devices such as my iPhone, iPad, MacBook, Kindle all can be charged for sure. Fully tested! More update will come up if I experience any problem during my trip in UK.
