Rotary USB Wall charger

3 This wall charger has two USB ports for charging iPhones and others gadgets on its round edges, so you can charge two devices at once. And the whole thing can rotate 90°, so if there’s something blocking you from plugging in at the sides, you move the ports to the top and bottom. (Putting ports on the front might be easier, but few chargers do this, to be fair.) It also has folding prongs for the plug, making it travel friendly (though these are a little loose). Sadly, its maximum 1A output isn’t high enough for the iPad, though. Matt Bolton

A smart design, and a useful travel accessory. However, we wish it could charge the iPad too, and had more secure plug prongs.
