Keychain-sized cables, we’ve seen. WonderCube outclasses them all with its extensive list of functions, doubling as a 3-inch long charge/sync cable when unfolded, a stand (thanks to a micro suction cup plate), an LED light, and a backup battery charger by plugging to it a standard 9V battery.
It even functions as both a memory stick and OTG (On-the-go) memory for Android devices thanks to a micro-USB card reader built into its USB plug. All this tightly packed into a compact, one cubic inch ABS plastic device.
