In this paper, we design, construct as well as test and analyze an electronic circuit that can be used as a solar portable charger for mobile phone devices using the solar energy as a source of electric power. A suitable small size solar cell panel is selected that is easy to carry to any locations farther from city electric grids. The alternative use of the solar energy as power source is helpful in outdoor emergency situations and avoids the traditional way of waiting beside an electrical sockets or outlets for charging. We suggest here a special electronic design and construction with an important merit related to controlling battery charging currents. Software verification and simulations, laboratory experiments on the circuit, practical testing to the charging capabilities; all these are discussed in this paper.
