Nothing is more frustrating than needing a USB cable for your iPhone and not having it around. The ZiPAC happens to be a case that can be turned into a USB cable. Just unzip the case to turn it into a USB cable. The developers are going to release microUSB and Lightning versions. The cable is covered in a durable, nylon weave material. It does not damage your phone.
ZiPAC is good looking, protects your phone, and serves as a USB cable any time you need one. The product is on Kickstarter.
