Increase the storage capacity and battery life of your iPhone 5/5s with the black mophie 16GB space pack. This protective case features a built-in 1700mAh lithium-polymer battery and 16GB of additional file storage. The internal battery in the space pack increases your phone's talk time by up to 8 hours, your video playback time by up to 10 hours, and your audio playback time by up to 40 hours..
The case's 16GB internal storage can be managed wirelessly through the Wi-Fi Space Portal for Mac, Windows, and Chrome OS. Files can also be transferred via the included micro-USB cable, and the files can be passcode-protected. The free mophie Space app for iOS lets you access your files on your phone, and those files can also be accessed on Mac or Windows computers as an Internet-free "cloud storage" system.
The space pack has LED indicators on the outside so you always know how much power it has left, and an on/off switch gives you control over when the case's battery kicks in. It also features pass-through charging and syncing, so you can charge your phone's internal battery and transfer data via the included micro-USB cable, without removing the case.
