The Mojo Hi5 Powerbank is a new case for the iPhone 5 that according to a report enables the user to remove the 2500mAh iphone extended battery from the case when desired, which enables the user to keep their shiny new iPhone as a slim handset when they do not need that extra power.
However apparently when you do need that extra juice to power your iPhone 5 it is reasonably quick and easy to simply slap that 2500mAh iphone battery extender back onto the case.
