Portable power supply using hybrid battery technology
First Claim
1. A portable power supply, comprising:
- a first cell of a first type, said first cell being rechargeable and having a first peak amperage and having a first discharge rate, the first cell including positive and negative terminals;
a second cell of a second type, said second cell having a second peak amperage and having a second discharge rate, said second peak amperage being smaller than said first peak amperage, said second discharge rate being slower than said first discharge rate, the second cell including positive and negative terminals; and
a housing, the first and second cells being positioned in the housing, the housing having positive and negative terminals, the positive terminal of the housing being connected to the positive terminals of the first and second cells, the negative terminal of the housing being connected to the negative terminals of the first and second cells, the housing having a handle capable of lifting and carrying the housing.

Abstract
A personal portable power supply containing first and second different types of cells or batteries of cells. The capacity and discharge rate of the power supply is such that it is capable of starting automobile engines on several different occasions without needing to be electrically recharged. The capacity is also such that it can power personal devices for relatively long periods of time. The first cell or battery of cells is chosen to have a high discharge rate and high peak amperage or cold cranking amperage. The second type of cell or battery of cells is chosen to have a high energy density and a low cost. The electrical characteristics of each cell or battery of cells is chosen so that the second type of cell is able to recharge the first type of cell during periods of non-use.
