Type-C USB 5V 2A Boost Converter Step-Up Power Module Lithium Battery Charging Protection Board DIY Charger,with Welding

Type-C USB 5V 2A Boost Converter Step-Up Power Module Lithium Battery Charging Protection Board DIY Charger,with Welding Description

When the load current is less than 50mA continuously, the output be turned off. It supports the external key, which is connected to the K point and the output negative pole. Short to turn on the power display and turn on the 5V output. Two consecutive short presses turn off the power display and turn off the 5V output. When the charging current drops to 100mA after reaching the final floating charging voltage, the charging cycle be 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 be pre with a current of 180mA. Type-C input, high accuracy of charging voltage. It supports discharging while charging. Note:power off operation is required to adjust the charging voltage setting Input voltage range:5 - 5.5V Charging cut-off voltage:(4.2v/4.35v) 0.5% Charging current:2.4a 5% Boost output voltage:5V - 5.15v (line loss compensation) Boost output voltage ripple:100mV Boost output current:2A Boost conversion efficiency:92.5% (3.6V input, 5v2a output) Static current at battery end:Less than 30uA Version:With Welding Colour:Black Material:PCB+electronic components Package Contents: 1 * 5V 2A Charge-discharge Integrated Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
