WonderCube has a built-in Lightning and microUSB cable, a micro-suction phone stand, USB key and microSD card reader, a USB connection, emergency 9V battery connection and mini torch. And all in a package no bigger than one cubic inch.
In other words, it can charge your phone, sync files and prop your phone up in either landscape or portrait by sticking to the back. In order to charge your phone 'on the move' you slot in a 9V battery, giving you around three hours extra talk time for Android and iOS devices.
It is a neat little device that packs a lot into a small package. And for $69 (£46), or $49 if you buy from Indiegogo, it's very affordable too.
