Great piece of kit
Fabulous phone the Galaxy S3 but the battery soon loses charge,I was fed up of charging it so I looked on MobileFun and found this Power Bank Case. Wow its brilliant my phone now lasts twice as long as it did. This piece of kit is easy to use and looks cool {love the blue lights}. Recommended if you play games and or watch films on the go.

Perfect External Charger
I use this charger everyday. I play poker, while at the poker table, I either watch a movie or listen to music. I will use the phone battery until about 20%, then switch over to the Bytech charger. Not only does it recharge the phone battery, but adds hours to the use of the phone. LOVE IT!

    Protective Case

    The Powerbank battery is built in to sleek and compact cover.  The case comes in two parts, just slide your handset into the first half of the case and on to the micro USB attached at the bottom of the case.  The second part then clips in and secures the phone in the case.   The case is made from a durable plastic and has a soft to touch feel.  So not only does it give you the extra power capacity but also protects the back of your handset from scratches and accidental dropping.
