Keeping your shiny new iPhone 4 powered throughout the day, while also retaining its sexy form factor can be difficult. The myriad of cases available with built-in battery packs add too much bulk.
Mophie, the leader in battery-embedded cases, have released their new Juice Pack Air for the iPhone 4 and put as much emphasis on style as they do battery power.
Featuring a two-tone, metallic design, the Juice Pack Air slips over the iPhone 4 and provides up to six additional hours of 3G talk time, five hours of 3G Web browsing and nine hours of WiFi Web browsing.
If you work away from a power cord all day and need to have your iPhone ready at all times, you might want to invest $80 for the added security of what essentially amounts to an extra battery.
