Happen to walk by some movie premiere and can't take pictures because your phone is dying? The iCruiser External Battery Pack will prevent that from happening.
The iCruiser External Battery Pack isn't a case that goes onto a smartphone -- quite the contrary in fact. This is an external, portable charger with a built-in 11000mAh capacity lithium ion rechargeable battery, which offers 50 hours of movie time for the iPhone or 17 hours for the iPad. The additional retractable USB cable also works on other advices which include Android and Blackberry mobiles, Nintendo DS and more.
The iCruiser External Battery Pack is a pretty nifty little accessory. Even if you don't want to bring it on a night out, it's still perfect to carry around for trips.
