Incase just launched this iPhone 4 battery case called the Snap which it says can extend the juice on your mobile device by 40%.
It’s got a built-in 900 mAh battery, features hardshell construction with a soft-touch coating, a female 30-pin connector for charging and syncing, an LED power indicator and control button, an included 30-pin to USB cable and open access to all ports and controls.
For sure, the Snap gives a little less of that piggy-back-bulk than competitor Mophie Juice Pack Air – and costs about $30 less at $60 than the Juice Pack.
$60 for a charger case isn’t exactly lunch money, but probably worth the back up if you face long commutes or watch a lot of battery-sucking video on your iPhone 4.
