The WonderCube packs 8 mobile essentials in a tiny 1 cubic inch cube.
You no longer have to carry a bunch of accessories for your smart phone as you travel. The WonderCube is attached to your keyring for ultra portability. It's a built-in cable, charger, phone stand, charger, sync cable, OTG USB, flash memory and led light. To charge your phone you can just pop a 9V battery onto the WonderCube and get about another 3.5hrs of talk time.
