Designing Universal Smartphone Case with Solar Powered Chargers

Abstract

The purpose of this research is to design a product to transform solar energy to electric energy that can be used to charge the battery of phones. Method used in this study is to design chargers that can be used anywhere is ulrich method. This method consists of some steps such as planning, developing a concept stage, planning system-level, detailed design, experiment, and improvement. The results are the charging process on a smartphone with a capacity of 1810 mAh battery is fully charged within 1 hour and 23 minutes. The output generated by the tool is 0.8 ampere and 5 volts. The price is below the maximum target specification that is worth 150,000. The conclusion of this research is the concept of designing universal smartphone case with solar powered chargers requires the stages of elimination and filtering to produce a solar smartphone case that is made of brecket also using a solar powered converter and power transport mode such as USB female port. The impact of this charger is the product can be used by people that likes to go to nature.
