You won't want to give Zack back! Its retractable USB cable and 2-in-1 plug for Android and iOS devices makes keeping your charging cables organized a cinch. Flip the top and pull the cables out to charge your smartphone or tablet via a power source and then when you are done, simply unplug the cables and give it a tug to retract the cables back into the rubberized case for easy storage and portability. No more tangled cables or getting your wires crossed. Cable transfers data between connected devices.
