Motorola USB Universal laptop Power Pack review P793
Motorola USB Universal laptop Power Pack P793 and design:
Review Introduction
Motorola Universal package P793 double charging portable power is really what you can expect from a mobile device – a thin juicer that can provide 1420mAh worth extra free to satisfy his craving energy from your mobile phone. MicroUSB cable built in compact package contributes to the feeling of this portable charger. The energy package is actually a slightly down to the business firm black body appearance and simple forms. The device has a height of 3.94 "(110 mm) and weight of 2.16" (55 mm) thin profile 0,23 "(10 mm). This overlapping scales in 1,92 ounces, making it an easily pocketable item, which you can carry around easily.

New Tech Could Power Cell Phones Through Sound
Talk about cool new technology! No, seriously—you should talk about a breakthrough by South Korean researchers in the conversion of sound into electricity, because that conversation could be what's powering your future cell phone calls.
"Sound power can be used for various novel applications including cellular phones that can be charged during conversations," said Dr. Sang-Woo Kim in a recent interview with The Telegraph.
Kim and his colleagues at Sungkyunkwan University's Institute of Nanotechnology in Seoul say they have developed a new method of converting sound into electricity. They say a cell phone could be charged simply by talking into it while other applications could include installing "sound-insulating walls near highways that generate electricity from the sound of passing vehicles."
Even when a phone wasn't in use, background noise could be used by the process to charge the device, Kim said.
"Energy scavenging" to power mobile devices is a growing field in the high-tech industry. Researchers have explored such areas as the use of movement, or kinetic energy, to top up gadgets without requiring a wall socket and a charger.
The Sungkyunkwan University team hasn't yet figured out a way to completely charge up a device using only converted sound. But Kim said the technology, which generates an electrical current via zinc oxide wires that compress and release when sound waves cause an absorbing pad to vibrate, should only get better when his team switches out the zinc oxide for a more efficient material.
"Our current output performance can be applied to various electronic devices with low-power consumption such as self-powered sensors and body-implantable tiny devices. We believe that we can realize more efficient sound-driven nanogenerators," he told The Telegraph.
At present, the prototype sound converter is able to turn about 100 decibels into 50 millivolts of electricity, according to the British daily.
