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.
