Best Battery Pack For The iPhone 4S

The iPhone 4S has recently been released by Apple, with the super fast dual-core A5 chip built-in plus an 8mp camera packed in the beautiful body of the iPhone 4. Apple have also included an amazing assistant named Siri, which lets u do nearly anything on your iPhone just by speaking to it. For example replying to a sms or email, setting a reminder, setting an alarm, searching for information and many other features. Although this assistant is a great feature, Siri has a huge drawbacks on the iPhone 4S. This is that you will need an internet/data connection to use it and therefore it drain your battery much faster especially if you are using 3G. Also with the A5 being a dual-core it uses more power than the previous A4 chip, used on the iPhone 4. Therefore below are a few battery packs which can solve the problem of battery life on the latest and best iPhone yet.
MPJ Portable External USB 2600mAh Cell Phone Battery Charger Power Bank is a powerful dual-charging port battery pack, which also has a great and stylish design. It is also very light and thin which allows it to fit in your pockets.
MPJ PowerBank 5200 mAh Extended Backup Battery is a very good battery pack which has less power than the MPJ Portable External USB 2600mAh Cell Phone Battery Charger Power Bank but is more heavy-duty and resistant to drops.
