External battery with cable that can be connected both to iPhone connector and USB

For Apple products such as iPhone and iPad, exclusive cables are required because the connection with the outside passes through a proprietary 30 pin connector (Dock connector) rather than a general purpose mini USB terminal or micro USB terminal. However, I would like to reduce the number of cables to take to the destination. In such a case it is helpful to use a single gadget with a cable that can be connected to the 30 pin connector of the iPhone as well as to the mini USB terminal and the micro USB terminal.
