InfinityPV designed a portable smartphone charger called ‘HeLi-on’. Inside, there’s a retractable powerful solar panel which generates the energy and a storage battery bank that stores the collected energy. On sunny days it will fully charge your smartphone in 2-3 hours. You can charge any smartphone using the USB port. HeLi-on will easily fit in your pocket because it measurements are just 11.3 x 3.6 x 2.8 centimeters and it weighs only 105 grams. It also has a LED charge indicator that shows the battery life at all times.
