The OREI 6000 is a high capacity, aesthetically beautiful, portable power supply. The PowerBank will charge practically any device - iPad, iPad 2, iPad3, iPhone (3G, 3GS, 4, 4S), iPod (all generations), Galaxy Tab, Android, eReaders, Kindle and many, many more. Simply connect your device to the PowerBank via USB cable and that's it! The PowerBank has 2 usb input ports so two devices can be charged at the same time! This is unique to the PowerBank - no other portable power supply/battery supports dual charging. The high capacity, 6000 MAH Polymer Lithium-Ion battery provides a huge amount of portable charge - enough, for example, to charge an iPhone 4 from empty up to 3 times! And it does this whilst maintain a slim, sleek, ultra-portable design. The display on the beautiful mirror surface, shows how much charge is remaining. The OREI comes with a USB cable - allowing connection to any Apple Device as well as micro and mini USB compatible devices. This cable can also be used to charge the PowerBank itself. Standard USB cables (i.e. the ones that came with your gadget/device) can also be used with the PowerBank.
