Portable power supply

A portable power supply comprising:

• a body case having two opposing major surfaces;
• an attaching portion provided on one of said major surfaces;
• of said body case for detachably attaching said body case to an article of clothing worn on a human body;
• an input portion provided exposed from said body case to be connected to a commercial power source;
• a voltage lowering portion contained in said body case for lowering voltage of power supplied from said input portion;
• a storage battery contained in said body case charged by an output from said voltage lower portion;
• an output portion provided exposed from said body case connected for supplying power charged in said storage battery to a prescribed electronic device;
• and
• heat radiating means formed on the other one of said major surfaces for making higher heat radiation of the other one of said major surfaces than said one of said major surfaces of said body case.

A portable power supply, comprising:

• a body case having a first section and a second section divided by a prescribed reference line;
• an attaching portion for detachably attaching said body case to an article of clothing worn on a human body;
• an input portion positioned in one of said sections of said body case, provided exposed from said body case to be connected to a commercial power source;
• a voltage lowering portion, contained at a position biased with respect to said prescribed reference line towards said second section, for lowering the voltage of power supplied from said input portion;
• a storage battery contained in said body case to be charged by an output from said voltage lowering portion;
• and
• an output portion positioned in one of said sections of said body case, provided exposed from said body case connected to supply power charged in said storage battery to a prescribed electronic device;
• wherein
• the center of gravity of said portable power supply is positioned in said second section.
