It is true that nowadays everybody wants to stay closer with their friends and relatives, wherever they are, but sometimes it is not possible, because of some reasons. One of them is that your smartphone is just “dead” and you start from that point looking for a place to charge your gadget, which sometimes, could be too difficult to do so. However, let’s forget about the negative sides and go directly to the solution. In that case, people all over the world are looking for portable device, which could fit into a backpack, and that particular device could charge your smartphone or laptop couple of times in any situation without a socket. Next fact is that it should be environmentally friendly and saves energy. Taking everything into consideration, portable solar recharger is one of the easiest solution nowadays. PICTURE 1. Portable solar rechargers (Smirniotis M.) As it has been tested, a basic solar charger could refill 13,000 mAh battery pack in about 8 hours, in addition it could directly charge smart phone and fill most of its 2,000 mAh battery in less than 90 minutes (Smirniotis M., 2015). Meanwhile, there are many different models of solar chargers right on the market. To choose the best one for yourself, take the following into consideration: power, portability and price. So, if you want a compact charger with a high power you need to pay a lot for it (Pierotti et al, 2015). It is true that there are different options to charge your phone. For instance, use the charger, which is consuming the electricity. From the environment point of view, it can be said that the solar chargers are environmentally friendly gadgets. The fact, that they are not consuming electric power, and use only energy taken from the sun, prove that case. It has been calculated, that the general 5 Watt/hour phone battery and a 2-Watt output solar charger you would needed 3 hours of direct sunlight to fully charge your battery. In addition, if you have 18 Watt solar charger, only 30 minutes is nedded. Even a solar phone charger could be done at home. Start by taking apart your solar lamp, the top usually snaps off, and then you have to unscrew the portion with the led and circuit board, unscrew the circuit board, and the light sensor, being careful not to damage any of the wires. Use the pliers to cut away excess plastic from around the battery casing, and to remove the on/off switch. You want it intact. After that, carefully remove the solar panel. Discard the led. Repeat with each solar light. Solder the battery compartments positive to negative, in a chain using some extra wire. Remove the part of your charger that plugs into your phone, soldering the wires to each end of your solar panel chain. Glue the panels around the record. Charge your phone using the sun (Goal Zero, 2013). All in all, solar power from a portable panel is still generally more expensive. However, if you do not have access to the grid and you need to power your device, a portable solar panel is often the only option. Finally, when you are generating your own power, you usually use way less. The usage of such charger is growing and in the nearest future, the prices will fall down and such devises will be easily accessible in the Third World countries. References Goal zero. 2013.
