mophie juice pack for iPhone 4 doubles battery for $80

Battery-case manufacturer mophie has put its juice pack for iPhone 4 up for sale, promising roughly twice the power of the Apple smartphone's own battery for $79.95.  The hard-shell case – which protects the back and edges of the iPhone 4, while matching the smartphone's color scheme – has a pass-through USB connection, for simultaneously recharging both case and phone while also synchronizing with iTunes.

As for the hard figures, mophie are saying up to an additional 6 hours of 3G talktime (or up to 12 hours of 2G), or up to 36 extra hours of audio playback, or up to 9 hours of video playback.  There's a four LED power gage on the bottom, and mophie even reckon the case "acts as a virtual speaker box" to redirect sound from the speakers underneath.
