USB signal line through, does not affect the normal USB communication.

Function description:

1,Screen rotation function: press the back button display interface will rotate 180 degrees, to adapt to the computer about the use of the two side of the USB port angle, and automatic memory for the net boot mode.

2,Off electric storage function: module shutdown will accumulate MAH automatically stored in the internal EEPROM, the net boot capacity will flashes to remind the last accumulative capacity until the cumulative capacity of more than 1mah. Last time data is automatically cleared and re start counting.

Calculate the capacity and efficiency of mobile power battery:

The Ah data of output voltage, battery voltage.Efficiency = mobile power battery Ah(output voltage is generally 5V, the battery voltage is generally 3.7V, the efficiency is generally by 85-90%)

3,Over voltage and under pressure:Instrument on the display of the voltage is less than 4.7V (charger output) or higher than the 5.3V (such as Samsung 5V2A, 5.3V2A, etc.)With line loss compensation, LCD charger)There will be an arrow on the blink., in order to prompt the voltage is abnormal, flashing can not be closed.
