Solar Powered Mobile Charging Unit

Abstract: Mobile and other smart devices keep on running all the time anywhere and everywhere, draining its battery. Recharging mobiles need certain time and suitable place. Sudden shutdown of mobile phones due to lack of charge, creates huge embargo for people who is in rush to workplace, market, school, college, office, train and bus station and so on. It would be great if we could facilitate these people with instant smart device charging opportunity through renewable energy harvesting, which they can avail whenever they need, on the go. Several researches have been done so far to fulfill this issue of providing itinerant charging facility to smart devices. Among those developments, some are portable while others are stable large charging stations but the common feature among those is that power generation of these systems are fully or partially based on one or more renewable resources of energy for example solar, wind, hand crank generator driven by physical movement etc. Most of these are for public use but some can be intended for commercial purpose too. This article reviews the types/ varieties of renewable sources that have been used for development of portable or stationary mobile charging stations, along with the features the system comprises.
