Abstract
A combustion heat powered portable electronic device. At least one thermoelectric module is sandwiched between a hot block heated by a combustion heat source and a cold-side heat sink and provides electric power to a portable electronic device from the temperature difference. An electric circuit provides power for purposes of operating the portable electronic device either directly or indirectly by charging a rechargeable battery which in turn provides power to the electronic device. In a preferred embodiment the combustion heat source is a catalytic combustion unit. The hot block and/or cold side heat sink can be integrated into a single unit with the thermoelectric module. In a preferred embodiment the cold side heat sink is cooled by fins cooled by air driven by a forced air fan powered by the thermoelectric module.
