Type-C USB 5V 2A Boost Converter Step-Up Power Module Lithium Battery Charging Protection Board LED Display USB For DIY Charger
Features:
:When the load current is continuously less than 50mA, the output will be turned off.
:Support external buttons, connect the button to point K and the negative output, short press to turn on the power display and turn on the 5V output, two short presses in a row will turn off the power display and turn off the 5V output.
:When the charging current drops to 100mA after reaching the final float voltage, the charging cycle will be automatically terminated.
:When the battery voltage is lower than 2.8V, the battery will be precharged with a current of 180mA.
:The USB-A female socket welding position is provided on the back of the product, and the female socket can be manually installed.
:Support charging and discharging.
:When the battery voltage drops below 4.1V, the charging cycle restarts.
