Mophie Juice Pack Helium
Not content with your iPhone 5’s battery life, but unwilling to compromise (too much) on aesthetics? Mophie’s Juice Pack Helium is as good as it’s gonna get, for the time being anyhow. Within Helium’s relatively slim profile hides a 1500mAh li-ion battery that basically doubles your device’s typical mileage: just flip the switch to activate the Juice Pack’s battery, effectively recharging your phone on the go. Our favorite feature: wireless syncing to iTunes without plugging in – simply flip the switch instead.
