Mophie’s Space Pack doubles your iPhone’s battery, storage, and size

Ars Technica:

The Mophie Space Pack does three things, but it doesn’t do them equally well.

This is an accessory that will appeal mostly to Apple die-hards who use their phones all the time and want to carry as much of their stuff with them as possible.

I’ve always been a fan of Mophie products but this one seems to be too much for me. Is it a product you’d be interested in?
