The latest in portable chargers, Mutants DesignLab's WonderCube is yet another step towards a future in which all of our tech comes integrated within a small number of devices. Weighing in at a paltry 20 grams, the keyring-appropriate cube takes up just one cubic inch of space. While the charging aspect is obvious, the crowdfunded device also features memory, a flashlight, bridging capabilities, and more. It may also be used as a stand for your cellphone.
The WonderCube ranges in price from $45 to $89, and can be bought in anticipation of final release via Indiegogo.
