Kinds of battery charger come in the market. Today I have seen a piece of news of battery charger which is protective case/battery charger that’ll increase battery life by 80%. This is an additional 6 hours of talk time and internet use on 3G, 7 hrs of video play back and 30 hrs of audio playback. This popular accessory works much the same as previous version. An included micro-USB cable connects the unit, and four LED lights on the case’s lower back panel will display its charge status. When you’re ready to charge up your phone, flip the standby switch for power on-the-go. If you’re playing music or on speaker, forward-ported speakers redirect audio towards you so that you don’t have to lay your iPhone facedown to experience optimized acoustics.
Of course, this is an ideal and great design. But I think this also have its weakness. It is easy to damage the iPhone’s battery if charger case covers it all the time. So the normal USB power bank is saver than iPhone case charger. Mystore365 introduce a 12000mAh charger for you here. This 12000mAh USB power bank emergency battery charger is applicable to all USB charging devices such as mobile phone, iPhone 4, iPhone 3G, iPhone 3GS, iPod, iPod Classic, iPod Touch, iPod Touch 2G, iPod Nano, PSP, MP3, MP4, PSP, GPS, digital camera, Bluetooth, etc.
