Besides carrying charger or take a backup battery and other traditional ways, how many charging methods do you know? There are actually quite a lot of special even very interesting charging ways. These special charging methods are very helpful for environmental, such as solar energy, wind energy and momentum, etc. For charging, many ways has evolved from the concept stage to our life living things.
Solar charger
Solar charger employs solar energy to supply electricity to devices or charge batteries. They are generally portable. Such as the solar laptop battery charger, it can automatically detect a smart charging voltage, comes with a voltage selection button to ensure full compatibility with a wide variety of electronic products, such as; MP3/MP4 players, portable DVD players, mobile phones, or any other USB powered device using the built-in 5V USB port.The more you use your solar charger, the less carbon dioxide you emit into the atmosphere. From day one, you will generate your own free, clean electricity directly from the sun. The amount of energy used to create yoursolar chargerhas been negated by removing unsustainable processes and using carbon offsets. This means that yoursolar chargeris a net producer of energy from the very start.
With sound waves to electricize
Sound is a kind of energy, too. American scientists at the University of Houston put forward the acoustic new charging ways. The principle of "is actually very simple, piezoelectric effect", driven by vibration and acoustic piezoelectric crystal, which produces energy for mobile phone battery. Because of the ordinary acoustic vibration is weak, the built-in phone piezoelectric crystal is very small, about 23 nano (the person's hair has about 10 million, the diameter of nano).
