6. Have over-charge, short circuit, intelligent identification of bad batteries and reverse battery detection protection.    
7. Charging mode, constant current constant pressure    
8. Using DC input, the charger power supply for the 5V-2A (Micro plug)
9. With standard 5V / 1000mA USB automatic identification output function, Third, the key, LED and function description
1. Press the key: hold the selector key for 2 seconds to switch 500mA 700mA 1000mA 2000mA charge current at power on, When charging the battery, press the select key to change the type of rechargeable battery. When the rechargeable battery type is selected (for example, 3.20V 3.85V) for 5 seconds, enter the charging state.
2. LED: charger connected to the 5V power supply, the charger all the LED moment all bright, if the battery is not put into the charging slot, 500mA (LED) indicator light is on, the other lights go out. When the battery is detected, the four LED lights are all bright,
3. LED light will flash, then press the button to select the type of battery you need to charge, if not selected, 5 seconds into the default identification of the battery charge, charge The indicator light flashes at the corresponding charge ratio. Press the button to check the charge type (no power indication) 5 seconds after the return to the state of charge. When not energized, insert the battery to view the power ratio (5 seconds after extinguishing, need to view again press) USB output indication: When the USB output is detected, the power indicator turns on for 10 seconds and presses to check the power.
