• Four charging current mode (500mAh/ 700mAhn/ 1000mAh/ 2000 mAh), 2000 mAh current mode is fixed only in the fourth slot
  

• The LED indicators show the charging progress: 25% -50% -75% -100% and  the type of battery (size): Ni-MH 1.2V, Li-Fe 3.2V, Li-ion 3.7V, Li -ion 3.85V
  

• Identify Li-ion and Ni-MH batteries automatically and manually adjust the charging mode of LiFePO4 battery and 3.85V li-ion batteries
  

• Update battery for OV. It does not charge any battery from 1.65 to 1.85V (update of the current can only be detected)
  

• Protection for overcharge and over-discharge and short circuit, identify broken battery and reverse polar inspection
  

• Low voltage and constant current charing
  

• Input interface by DC and operating voltage is 5V-2A (Micro plug)
  

• Built with 5V / 1000mAh USB discharge (output) function
  

Button, LED and function:

-Buttons: While the electricity is connected, 1) press the button to  change the battery type, start charging 5 seconds after adjusting the  type of battery (3.2 V or 3.85 V), 1.2 V Ni-MH and li -ion 3.7 V AC is detected automatically, so you need a set of only 3.2 V and 3.8 V batteries; 2) change the current load current amount 4 at any time during charging by long press on the button

-LED: While connecting to 5V input, all LEDs light up immediately 1) If  no battery is put on, 500mAh LED goes on and others will turn off. 2)  When the battery is detected in, 4 LED lights and 3.7V LED keep  flashing to indicate to set the battery type, if no operation, it will  start charging 5 seconds after automatically under detection, four LED  lights will show the state of charge. 3) Press the button. can show the battery type for 5 seconds. 4) No electricity is connected, insert a battery can quickly shows the volume of the remaining battery.

-USB output indicator: To the detected USB download port, battery  volume indicator will light up for 10 seconds and exit, press the button  to turn on again.

-LED show reference chart
