Product Introduction:
1.Input Voltage:5V
2.Charging Cut-Off Voltage:4.2V±1%
3.Maximum Charging Current:1000mA
4.Overdischarging Protection Voltage:2.5V
5.Overcurret Protection Current:3A
6.Board Size:2.6*1.7cm

Notice:
1.Testing Current Meter can only serial conenct with charging board 5V input port
2.Charging current should be battery capacity 0.37C, that is 0.37 times
3.Charging connecting cable should not be too thin and long
4.Make Sure that connecting with battery perfectly
5.If 5V input voltage is a little high, such as 5.2V or 5.5V, it will cause charging current cannot reach 1000MA.This is normal phenomenon.
6.Input transposition hasn't impact on chip; but output transposition will burn the chip
