FUNCTION
When the load current is less than 50mAcontinuously the output will beturned of f.
Support external key connect the key to K point and output negative poleshort press to turn on power display and 5Voutput continuousTwo short presses will turnoff the power display and turnoff the 5Voutput.When the charging current dropsto100mA after reaching the final floatingcharge voltage the charging cycle wil be automatically terminated .
When the battery voltage drops below 4.1V the charging cycle starts again .When the battery voltage is lower than 2.8Vthebatterywilbep rechargedat180mA.
Usb-abase welding position is provided on the back of the product whichcan be installed manually .
It supports discharging while charging .
