I got this device mainly so I can charge my iPhone with it. first time it worked great but then other time a message would appear on the iPhone saying that this device is not meant to work with the iPhone. It takes a few tries for it to charge. As this is mainly Apple's fault for creating more problems than solutions when working with products they do not sell them selves, I feel the manufacture of this charger should have placed a comment saying "May not work with apple products". In any case, with the rest of the products it works. fairly simple to use and does not weight much.
