Battery purchased in order to increase the power of my iPhone during road bike outputs to run intensive applications GPS resources. Very good well the finished product to the French far from the Chinese standard assembled in a hurry. In addition to a broad set of connectors included in the box. Keeping the batteries an excellent iPhone to load. I highly recommend this product because takes up little space and product that is used on my iPhone 4 but iPad mini ... In short, the top French and more to more affordable that ... Super purchase.
