WonderCube is a 1-inch (2.5 cm) cube keyring that’s designed to function as a numerous accessories for your iOS or Android smartphone. 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.

The second major component of the WonderCube is its ability to provide users with extra storage via the inclusion of a microSD reader, supporting cards up to 64 GB. Direct file transfer between a smartphone and the accessory is currently only available with Android devices, but the crowdfunding campaign includes a stretch goal for the development of an iOS app.

As if that functionality wasn’t enough, the little device also packs a flashlight (3 mm or 0.1 inch wide LED with a 3 V button cell) and has a micro-suction cup plate on one side, meaning you can fix it to the back of a smartphone and use it as a stand. Lastly, there’s a full-sized USB connector, meaning the WonderCube can be used as a bridge to connect a smartphone to a computer for backing up or transferring files.

As the WonderCube is a crowdfunding effort, there’s no guarantee that it'll make it to market. However, if you’re interested in the little cube becoming a reality, you can make a pledge over on Indiegogo, where the project is aiming to raise US$50,000.

The $30 super early bird pledges are already sold out, with single WonderCubes now starting at $45. The team is targeting a $69 final retail price for the accessory, and assuming the campaign is successful, aims to ship initial units in August.
