Tourism in our time has become one of the most popular types of outdoor activities. It's nice to get out of the hustle and bustle of the city to the virgin nature with friends or family, explore the unexplored spaces and conquer mountain peaks. But, no matter how attracted by the lack of civilization and the novelty of sensations, a modern person can hardly do without his favorite gadgets: a phone, player, laptop, tablet, camera, navigator and a host of other useful little things. Until recently, this was a rather big problem, because all these devices were discharged on the very first day of the outing, and after that they became useless cargo. But today there is a convenient and very practical solution - Solar Battery Backpack.
Typically, solar panels are located on the most sun-exposed front of the backpack. The design of the backpack provides for them a special pocket-compartment that fixes the batteries and protects them from mechanical damage. The battery itself is thin, flexible sheets with thousands of photovoltaic converters needed to transform the sun's energy into electricity. The resulting energy is stored in a battery with a USB port, for which there is also a special place in the backpack.
