How Cheetah Charge USB Charger Works?
(EMAILWIRE.COM, September 24, 2014 ) Eugene, Oregon -- Computers, laptops and other devices that have built-in USB (universal serial bus) ports come with a cable, or more popularly termed as connector.
Joe Schulz, Cheetah Charge marketing manager said a USB cable or connector works on two things to charge the device and transfer files from the device to a laptop or computer.
"A USB charger recharges the device through the USB port, which also serves as a
5-volt power source. It is the USB socket's outside pins that provide the 5-volt power supply, measured in milliamps (mA)," he explains.
He said the three specifications of USB are available -- USB 1.0, 2.0 and 3.0. The most common of these three is USB 2.0.
"A USB port also comes in three kinds, each of which supplies different amount of power -- a standard downstream port, a charging downstream port and a dedicated charging port."
Schulz added that a standard downstream port in USB 1.0 and 2.0 can deliver up to 500mA power while in USB 3.0, it goes up to 900mA.
Meanwhile, the charging downstream and dedicated charging ports can supply up to 1500mA. Literally, a Cheetah Charge usb charger works by plugging one end of the cable onto a computer or laptop with a USB port, which serves as the host, and connecting the other end to the device to be charged.
When the device is plugged in, it is initially allowed to get up to 100mA while still in the process of enumerating and negotiating its current budget with the host. In the USB 2.0 specification, the device would know how much power a USB port can source during enumeration and configuration.
After initial configuration, the device may be allowed to draw up to 500mA or remain at 100mA. Not all USB chargers, cables and connectors are the same.
"You have to choose the one that best suits your device. Check if the charger is capable of full-feature operation especially if the device has a dead battery," he concluded.
