I too thought that the cell phone adaptor was missing from the box. However, upon closer inspection, you will find a card that you must send in to the manufacturer to get the proper adaptor for your phone. Once you've done that, you will be sent the appropriate adaptor for your specific phone within a few weeks. At this point in time there is no standardization of cell phone chargers (which is unfortunate) so this is how they address this issue. This is a very handy device and great in a power outage.
