Abstract
A cellular phone charging device including two separate solar panels and a battery/switch containing unit. The two panels are hingedly connected together, and the battery/switch containing unit is hingedly connected to the back side of one of the panels. The assembly is pivotable between a retracted configuration in which the three component parts lie in parallel planes, and a deployed configuration in which the two solar panels lie in one plane and the battery/switch unit lies in another plane angularly intersecting the solar panel plane. The device is selectively operable in three different modes; namely a first mode in which the solar panels are connected to charge or power a cell phone; a second mode in which the solar panels are connected to charge its internal battery, and a third mode in which the internal battery is used to charge or power a phone coupled to the device.
