Boost Efficiency: 92.5% (3.6V input, 5V2A output)
Quiescent current at the battery end:
Function introduction:
The output will be turned off when the load current is continuously less than 50mA.
Support external buttons, connect the buttons to the K point and the output negative pole, short press to turn on the power display and turn on the 5V output, two consecutive short presses will turn off the power display and turn off the 5V output.
When the charge current drops to 100mA after the final float voltage is reached, the charge cycle is automatically terminated.
When the battery voltage drops below 4.1V, the charging cycle starts again.
When the battery voltage is lower than 2.8V, the battery will be pre-charged at 180mA.
The back of the product provides a USB-A receptacle soldering position, which allows the receptacle to be installed by hand.
It supports charging and discharging at the same time.
