The purpose of this project was to design, build, and implement an autonomous portable USB charger to charge USB devices. A single IC MAX756 which acts a buck booster was selected to achieve the task. A DC voltage of 3.5V is converted to 5V and fed into the device using the buck boost converter. This will use only the power from the DC AA batteries instead of using the conventional power from the AC mains. This special property of it enables us to charge our gadgets more efficiently with expended range of compatibility.
