Mophie today announced a new 64 GB version of its Space Pack for the iPhone 5 and 5s, which is currently available for pre-order on the company's website. First introduced in January of this year, the Mophie Space Pack is a 1700 mAh battery case that includes built-in storage.

The Space Pack aims to double the battery life of the iPhone while also increasing the built-in storage space. Originally only available in 16 and 32 GB capacities, the new 64 GB option doubles the storage space of Apple's highest capacity iPhone.

Using an accompanying Space app, the Space Pack can store photos, videos, music, and more. Accessing files does not require a data or Wi-Fi connection, and content like music and movies can be played directly from the Space app.

The 64 GB Mophie Space Pack, currently only available in black, can be pre-ordered from the Mophie website for $249.95.
