The 411 On Solar Cell Phone Chargers
Solar chargers of one variety or another have been around for years and they work by converting sunlight into electricity. Some of the first practical applications were done by NASA for space flights. Since then, they have been adapted by many other electronic devices. They can come in very handy in case of a power outage, or if you find yourself stuck out in the middle of nowhere, with no available electric outlet.
How They Work
Electrical currents are created from the movement of free electrons. These free electrons carry a negative charge and normally they revolve around the nucleus of an atom. When they are in orbit around the nucleus of an atom, they are called neutrons and protons, and have a negative and positive charge respectively. These are the building blocks of all life forms. Some of these atoms hold their electrons more tightly than others, but if enough energy is applied, an electron can be dislodged from this orbit.
The most effective energy particles to do the job of knocking electrons from an atom’s orbit is a photon. A photon is the basis for light, and they pack enough punch to knock an electron from their orbit and do it in the element silicon. Silicon is the material used in most cell phone batteries. The end result is an electrical field is created in the silicon.
Phones That Support Solar Cell Phone Chargers
While solar cell phone chargers are fairly new on the scene, they can be very handy if certain situations arise. The Apple iPhone is compatible with many cell phone chargers, and its companion electronic devices the iPad and iPod are as well. Many of them that work for the iPhone will also work on other cell phones. Most solar chargers can only charge one device at a time, and the cost of these units can go from $20 and up.
Some of the other cell phones that are known to work well with solar cell phone chargers include the Nokia, Samsung, and Sony.
Stay away from cheaper devices. Many of them will charge your device so slowly that they are of little to no use at all. So how do you know if your cell phone is compatible with a solar charger? Easy! Just look and see if it has a USB port 2.0 or higher or a mini-USB port. If it does, chances are your cell phone can be charged with one.
Tips for Shoppers
The best solar cell phone chargers come complete with several adapters. The most important adapters that any of these units should come with is the mini-USB and iPhone connectors. You also need to find our before you buy just what sun conditions are required for the charger to work. High quality chargers can work on a cloudy day, while others require exposure to direct sunlight to get the job done.
Your cell phone is your link to the outside world. In certain situations, it may even save your life. So having a reliable charger with you at all times is essential.
