Abstract
A portable self-contained power pack is described including a miniature internal combustion motor/alternator combination with an attached fuel supply. The electrical output from the motor/alternator is rectified and controlled to provide a DC output. The DC output is used to charge batteries and/or capacitors. The power pack is designed to be of a weight and size so that it may be carried while in use on the person of the user. The DC output and the batteries and/or capacitors are connected and power personal items. These personal items include, but are not limited to, cell phones, portable radios, laptops, stand alone computers, music and video players and recorders, personal electronic organizers, games and cordless power tools.
