present a real product for mobile geeks it is a backup battery! no bigger than a credit card, 5mm thick! This battery is equipped with a micro USB cable that completely fits into the edge of the battery into a compact and united object (be careful with my concerns, I have an iphone, I do not know if is a micro usb adapter / iphone would be nice to really use it) the battery comes with a micro USB / USB cable that comes removable plug into it then sector with an adapter (not supplied) The +: amazon book his product in a compact cardboard and with links to a small velvet bag to store everything in it, I loved this detail that protects the product Another +: price, it's worth it
