First Claim
1. A portable power supply, comprising:
- a body case;
an attaching portion 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 and capable of being connected to a commercial power source through a connecting cord;
a voltage lowering portion contained in said body case for lowering the voltage of power supplied from said input portion;
a storage battery contained in said body case, charged by an output from said voltage lowering portion;
an output portion provided exposed from said body case and capable of being connected to a prescribed electronic device through a connecting cord for supplying power charged in said storage battery to the device; and
a cord connected to said output portion, said cord including a tip end portion having a plug portion with noise preventing means.

Abstract
A portable power supply has a body case, an attaching portion, an input portion, a voltage lowering portion, a storage battery, an output portion and heat radiating means. The body case has two opposing major surfaces and two sections divided by a prescribed reference line. The attaching portion is provided on one of the major surfaces for detachably attaching the power supply to a human body. The input portion and the output portion are positioned in one of the sections to be exposed from the body case. The input portion is connected to a commercial power source, and the output portion is connected to a prescribed electronic device. The voltage lowering portion lowers power from the input portion. The storage battery is charged by the output from the voltage lowering portion. The heating radiating means is provided on the other one of the major surfaces of the body case and makes the heat radiation of the other one of the major surfaces higher than that of the one of the major surfaces. Center of gravity of the portable power supply is positioned in the other one of the two sections.
