Power Bank Case for Galaxy S3

Whilst looking for accessories to test on the Samsung Galaxy S3 we're currently reviewing I stumbled upon the Power Bank Case for the Galaxy S3. This case fits around the Galaxy S3's sleek frame and it's fair to say it adds quite a bit of thickness to the device, however this case provides an extra 2200mAh, effectively increasing the Galaxy S3's already massive 2100mAh battery to a gigantic 4300mAh which is about 4x larger than most smartphone batteries. 

MobileFun should be providing us with one of these cases to do a review on whilst we have the Galaxy S3, it will certainly make for a interesting review if you suffer from bad battery life on your phone.
