ABSTRACT:
One or more circuit-breakers (20 and 32) are installed into power pack circuitry 10 to prevent fire and destruction of the power supply 12 and circuits as a result of shorted components. One or more additional circuits 30 allow simultaneous use of more than one device or provide for a backup device should the first circuit fail. The circuit-breaker (20 or 32) permits quick recovery of the circuitry in dangerous situations such as mining or hunting activities. Batteries 12 of a power supply are attached to a specially designed adjustable belt 40 that allows the weight of the power supply to be positioned over the hips of a user thereby reducing back strain and discomfort. The weight of the power pack is further distributed over the user's body by means of a shoulder harness 70.
