Abstract:
1. A portable power supply system to provide power to an electrically powered device having at least two electrodes configured to provide an electrical potential therebetween and a set of at least two contacts accessible from an exterior of the electrically powered device and electrically coupleable to the at least two electrodes, the portable power supply system comprising: a power source including at least one cell selected from a group consisting of a chemical battery cell, an ultra-capacitor cell and a fuel cell; and a first magnetic coupling element coupled to the power source and that is magnetically-releasably attachable to the electrically powered device to retain the portable power supply system directly to the electrically powered device without the use of mechanical fasteners or adhesives such that at least two electrical contacts of the power source electrically conductively couple to respective ones of the at least two contacts of the electrically powered device to provide electrical power to power the electrically powered device in response to the portable power supply system being magnetically retained to the electrically powered device by the first magnetic coupling element.
