Andrews mobile phone data cable is a USB interface, the other end is called the Micro interface, full name is Micro-USB interface.

Micro USB is a portable version of the USB 2.0 standard, smaller than some of the mobile phone using the Mini USB interface, Micro-USB is the next generation of Mini-USB specifications by the USB standards organization USB Implementers Forum (USB-IF) in 2007 January 4 to complete the development. Micro-USB support OTG, and Mini-USB, is 5pin.

The Micro family includes Micro-B slots for standard devices, Micro-AB slots for OTG devices, Micro-A and Micro-B plugs, and cables.

Modern mobile phone power management is perfect, mobile phone battery is full, the charger at light load work, the output current is very small, because the battery is basically full, can flow through the current is very small. This time is often automatically stop charging the chip, the battery into the discharge mode. While also using an external charger, work together.

Theoretically, there will be no damage to the cell phone because there are a lot of protection mechanisms in control of this process. However, considering the connection of the charger, the system becomes complex, the probability of problems will indeed become high, so full of pull or not pull, by your own decision. Taking into account the security, unattended occasions, it is recommended to unplug the charger.

According to the voltage on the charger, the voltage is generally printed on the charger's surface:

If it is 100 ~ 220V, it can be used in Taiwan,

If it is 220V, it needs to bring a conversion socket.

Charging line connected to the four lines, red, black, respectively, said 5V positive and negative.

As shown below: The meaning of each port are as follows:

1) on the right 1 #: then VCC +5 V voltage, is the red line;

2) on the right 2 #: then D-line negative, is a white line;

3) on the right 3 #: D + data cable is positive, is the green line;

4) Right 4 #: connect to GND ground (that is, 0V), is a black line.

The frequency is different according to the voltage of different countries.

China single-phase electrical frequency is 50Hz. Preliminary statistics, the global single-phase power, the basic only two frequencies 50Hz, 60Hz, and the voltage is different, 100,110,120,127,220,230,240 range.
