10K - 130mA
5K - 250mA
4K - 300mA
3K - 400mA
2K - 580mA
1.66K - 690mA
1.5K - 780mA
1.33K - 900mA
1.2K - 1000mA
Notes:
1. The Ampere meter can only be connected to 5v input port of the module.
2. It is better that the charging current is 37% of the battery capacity. For example, the charging current should be 400 for the 1000mAH battery.
3. The connection wire should not be too thick.
4. Make sure the connect point is good.
5. If the input voltage is too high, For example 5.2V or even 5.5V, then the charging current will be less than 1000mA, it is normal. When the voltage is too high, the chip will automatically reduce the charging current to protect the chip from burning damage. Besides, it is normal that the chip feel hot when the working temperature of the chip is around 60°.
Package Includes:
1 x MICRO USB 1A Lithium Battery Charging Power Module TP4056
