The product, which is currently the subject of a crowdfunding campaign, promises to function as an emergency charger, a storage solution, an LED torch and more.

While the WonderCube packs a whole lot of functionality, its primary focus is keeping a user's smartphone charged. It's flexible 3-inch (7.6 cm) foldout cable is available in both micro-USB and Lightning varieties, making it compatible with both the Android and recent iOS smartphones. The idea is that the device replaces the user's charging cable, giving them one less thing to carry around.

Of course, it's sometimes not possible to plug your smartphone in to juice it up, but the WonderCube has you covered there as well. Opening up the top of the accessory reveals an adapter for a standard 9V battery. Clip one in, plug in your phone and you're promised another 3.5 hours of talk time.
