Good news for smartphone owners. There was a curious invention called WonderCube. This is a tiny 1-inch key chain, capable of replacing 8 accessories.
That fit into such a small square case? A lot of useful things, required for each holder mobile devices.
“On board” has a flashlight, memory card slot, sockets, USB, microUSB and Lightning (in a separate version). Cube easily turn into a compact stand – on while watching a movie or a video.
There is a unique jack traditional batteries. For example, a 9-volt battery. This allows us to use as a portable WonderCube “battery.”
In addition, key chain can charge the phone from a laptop (or desktop PC). With the transfer of files is also no problem.
Authors of the project have already collected on Indiegogo the necessary amount for mass production. In the open sale of the unit will be in August 2015.
Pre-order price – $ 49.
