Description

• 22.5W Quick Charging Mobile Power Module QC4.0 PD3.0 5 Port Dual USB Mobile Power Bank Circuit Board Protection Diy Motherboard

Product parameters:|The charging process is divided into the following three processes: trickle mode, constant current mode, constant voltage mode. When the battery voltage is lower than 3V, the charging module is in trickle mode and the charging current is 300mA. When the battery voltage is greater than 3V, the charging module enters the constant current mode and charges at full speed according to the set target current, with the power of about 21W. When the battery voltage rises to the target charging voltage (such as 4.2V), the charging module enters the constant voltage mode, and the current gradually decreases while the terminal voltage of the battery remains unchanged. When the charging current decreases to the charging cutoff current, the charging ends. If the battery voltage drops to 0.1V lower than the target charge, the battery automatically starts charging again. (
Notes:
If the voltage exceeds 4.2V, it is normal and will not damage the battery. If the voltage is 4.2V, the lamp still flashes, which means it is not full yet. Full charge is not just to see the charging voltage.)

The motherboard has a total of 5 USB ports, Are respectively the Type A1 + A2 + Type Micro - B + C + 20 Type, including the Type A1 and Type - A2 support QC3.0 / QC2.0 AFC/FCP/SCP/PE2.0 / PE1.1 / SFCP/VOOC quick charge output;

Type C support PPS/PD3.0 PD2.0 / QC4 + / QC3.0 / QC2.0 AFC/FCP/SCP/PE2.0 / PE1.1 SFCP quick charge output, support PD3.0 PD2.0 /

Notes:

1: motherboard external battery line needs to be able to pass 10A current, at least with more than 1 square copper wire, ordinary line to use 1.5 square. It doesn't have to be too thick, but it shouldn't be too thin. Too thin could be a safety hazard. (because there is a lot of current at the battery end)

2: The motherboard comes with a protection chip, the battery can not be added to the protection board, if there is please remove the protectio
