Mu Plug

2 This is a genius idea. When not in use, Mu Plug folds flat, as shown in the picture. But when you need to charge your iPhone, iPod or other USB-charged device, snap back the wings and twist the lower prongs, and it’s a USB charging plug, as also shown. The problem of bulky British three-pin plugs is solved at last. Mu Plug usually costs £25, but it’s currently ten pounds cheaper on Amazon. It doesn’t currently carry enough power to charge an iPad, but a tablet version is on the way.
