New York City is well known as the City that never sleeps and was ruined by the loss of electricity to the residents in the city and region. The lack of electrical power to the residents of New York City pressured a huge number of people to line up at public battery charging stations, that had been established by volunteers throughout the Area of New York, with the intention of being able to help people charge their portable mobile devices. There had been plenty of people that lamented that the extensive wait to charge their mobile phones, that ranged from three to five hours, in the icy 40 cold, only to obtain thirty minutes of charging time for their cell phone as a result of the strict rationing by most of the volunteers, who said it was necessary because of the scarcity of electricity and the long lines of people waiting. There was numerous sad people in the area that decided that it was far better to stand and wait around on the long lines, in order to make use of the public payphone, since the distance to go to a local charging station, for their cellular phone charge, had been too far to travel, since a lot of the public transportation was not working, inside the city. One resident stated it was a total catastrophe for everyone.

There had been a questionnaire that was conducted, while people were waiting in a long line, at one local charging station, that's very revealing because the query asked of the participants in line had been, if they had actually heard of a solar powered battery charger and amazingly the majority of the waiting folks that were polled, just shook their heads and stated no. One of the other great advantages of these kinds of battery chargers, is that they are super easy to use, portable and amazingly very compact. The battery charger very easily converts the UV rays of direct sunlight, which is called solar rays, into electricity. Big and small devices benefit dramatically, by this energy transformation, which can be converted to a practical form of electrical current, which powers the electronic and electrical gadgets. These kinds of solar battery chargers, comes in a wide variety of sizes, capabilities, and shapes.

Examples include; a battery charger that is meant to charge only 12 V NiCad electric battery banks. The sort of battery charger is normally referred to as the trickle charger or a battery maintainer, for Automobile and Boat electric batteries. These larger sort of solar power battery chargers, also incorporate the usage of a built-in charge controller inside of the charging system. On the smaller types of solar power chargers, the controller is normally typically called smart charging technology or a smart battery charger. These over-current devices are are all specially designed to shield the battery from any chance for overcharging.

Solar power chargers in the smaller sized variation, are primarily produced to charge electronics and also portable electronic devices such as mobile telephones, lap tops iPads iPods etc. For instance, it's a great device to take with you anywhere to ensure that electrical energy needs are there, anytime, anyplace or whenever you are on the move. This smaller form of the solar battery charger, comes in a wide variety designs, stylish colors as well as various inner storage battery capacities, as well.
