main features

1: Small volume. Smaller than similar products.

2: 4. 5-5. 5V power supply, suitable for single lithium battery (parallel connection is not limited), MAX1.2A, Use a stable 1A current as required.

3: Suitable for various types of 3.7V lithium batteries, including 18650 and composite batteries.

4: Equipped with over surge and over discharge protection, over discharge protection 2 9V, Charging cut-off voltage 4.2V

5: Automatically switches to output mode when there is no external input voltage, supports low current output of 5V, and outputs around 450ma. If outputting 1A, the voltage will be around 4.9V-4.5V depending on the battery level.

6: Automatically switch input and output, charge the battery when external voltage is input, otherwise discharge, the charging green light flashes, the fully charged green light stays on, the light does not light up when discharging without load standby, and the blue light lights up when discharging with load. The standby power consumption is about 0.8mA.

 

Usage

The module can be used by connecting the positive and negative poles of a 3.7V lithium battery. The module itself comes with overcharge and over discharge protection, and the lithium battery can also be equipped with a protection board.

The Type-C port, solder holes, and reserved input/output interfaces on the back are the same and directly connected on the circuit, so there is no significant difference between the three sets of interfaces.

Function Introduction

When the charging current drops to 100mA after reaching the maximum float charging voltage, the charging cycle will be automatically terminated.

The charging current is MAX1.2A, and when used properly, it can stabilize above 1.1A while ensuring the power supply.

 

precautions

Do not reverse connect the battery, connect it to the reverse burning board.

Before connecting the battery, first connect the charging head and test whether the charging light of the module displays normally.

The wire cannot be too thin, otherwise the power supply current cannot keep up. The wire must be welded.

Batteries can be connected in parallel, not in series. It can only be a 3.7V lithium battery, fully charged with 4 About 2V.

This product is not intended for use as a power bank and has a relatively low power output, with a MAX of only four to five watts. And it doesn't come with a charging protocol. It may cause problems with the use of some mobile phones, so when it comes to modifying power banks, our store is not responsible for any usage issues with some phones.
