The board was taken from new and non-used power bank, the charging control chip is IP5318

Before buying, you must be optimistic about whether the phone supports QC2.0 QC3.0 DCP BC1.2 fast charge protocol, does not support only the default 5V charge.

 

It is suitable for polymer rechargeable lithium Li-ion battery.

Access battery requirements: 3.3-4.2V polymer Li-ion battery:

Do not connect other batteries, such as 1.2V nickel-metal hydride batteries, 3.2V iron-lithium batteries, all dry batteries, 12V lead-acid batteries.

The battery current requires more than 3A to discharge and charge. Please do not use a battery with high internal resistance.

When you combine several battery in parallel, the battey should be in same voltage and resistance.

Immediately after the battery is connected, the board is usually activated to have an output.

 

B+ is the positive batter,  B- is the negative battery negative
Notes: polarity should be connect correctly, or ban the chip.

 

 

parameter:

1. Input USB model; Micro USB (support protocol fast charge input)

                            Type-C (does not support protocol fast charge input)

2, input voltage; 5-12V (fast charge protocol automatically adjusts the voltage)

3, charging current; 3100mah (fast charge protocol automatically adjusts the current)

4, charging method; automatic adaptation

5, output 1 USB fast charge mother

6, the output voltage is; 5V-12V ± 0.3V (fast charge protocol automatically adjusts the voltage)

7, the output USB rated current is; 3.1A (fast charge protocol automatically adjusts the current)

         5V3.1A/9V2.0A/12V1.5A

8, discharge efficiency: >85%

Support Apple 2.4A and Samsung 2A fast charging, the operation steps press the switch, the light is on and then plug in the charging cable to connect the mobile phone. This test with the detector does not guarantee to identify each model of the mobile phone, or Qualcomm QC3.0 and QC2 .0 protocol is fast charging.
