samsung galaxy s2 i9100 extended battery case

While smartphones have increased in power and decreased in size exponentially over the past few years, the one thing that hasn't improved is the battery. While 5 years ago you could expect your phone to last a week before needing to be charged, now you can hardly expect more than a day from the top handsets. With that in mind, QYG have released a powerful external power pack for the Galaxy S2, which extends your standby time and talk time by up to 9 hours. It is also designed to complement the sleek shape of the Galaxy S2, and so is thin as not to add too much bulk to the phone. The battery has a capacity of 1000mAh.

In order to function as an external battery, the case has to plug into the charging port at the bottom. However, within the case lies an integrated port for use with your existing cables and chargers. On the front of the power pack is a multi-coloured LED status indicator that gives you an idea of the current charge level of the battery at the press of a button.
