ABSTRACT
Technological development in the third world nation like Nigeria should incorporate finding solutions to seemly small problems like while trying to plan for the big ones. This statement is necessary given that Nigeria having been able to launch NigeriaSat I and about to launch another code named NigeriaSat 2, would be said to be progressive in their approach to technology acquisition and indeed retrogressive applying same to solving little problems.
The need for a home used charging device is timely, given that daily avoidable accidents occur on our highways due to SLI (starting, lighting and Ignition) faults in motor vehicles.
