Galaxy S3 extended battery case doubles your battery life

There's no denying that the Galaxy S3 has got some legs. Even after a two year shelf life with both the Galaxy S4 and Galaxy S5 taking the spotlight, the S3 remains the favorite daily driver of many. But as with many smartphones, the battery life could be better. Well, now it is, with the MobileFun extended battery case.

The Galaxy S3 extended battery case doubles the battery life of your smartphone! 

 

The MobileFun Power Bank for the Galaxy S3 follows a familiar pattern: just drop your S3 into the ''cradle'' case and hit the power button on the case when you want to transfer the stored charge to your handset. You can keep the case on as an admittedly rather bulky protective shield, or just keep it in your bag for those emergency moments when you need to recharge on the go. It's capacity is 2,200 mAh, which will double the run time of your Galaxy S3. Your camera lens, flash and speaker all work as normal through cutouts in the case design and the case weighs in at just 83 grams.

Camera, flash and speaker work through cut-outs and there's a fold-out kick stand. 

An added bonus comes in the flip-out kickstand on the back of the case, making watching movies a breeze. LEDs arrayed along the bottom edge of the device let you know how much juice you've got stored up and all it takes is the tap of a button to start the power transfer. Unfortunately, pass-through charging is not supported (allowing you to charge the S3 while it is in the case). You must charge the phone and case separately, unless, of course, you are charging the phone through the case! You can pick up the Galaxy S3 battery case through MobileFun's website for around 50 USD. They ship globally.
