This is a miniature battery charger based on the TP4056 integrated circuit. It is ideal for adding an embedded battery charger to your new project.
Charge Li-Ion batteries from onboard Type C USB connector from USB or external +5V source.
With C Type USB onboard connector, you can directly connect to computer USB port for battery charging. If USB is not available you can use an external source voltage at IN+/IN- pads great for DIY projects
Input voltage: 4.5V~5.5V
Fully charged voltage: 4.2V
Charging current: 1A adjustable (Set originally to 1A)
Working temperature: -10’C~85’C
Charging method: Linear charging 1%
Charging precision: 1.5%
Charging indicator: Red light charging, Green light fully charged
Interface: Type C USB
Size : 25 x 19 x 10mm.
Ampere meter can only be connected to the 5v input end of the module.
It is better that the charging current is 37% of the battery capacity. If you charge to the battery of 1000mAH, current of 400 is enough.
The connection wire should not be too thick.
Make sure the connection points is good.
If the input voltage is too high, like 5.2v, the current will be less than 1000mA, it is normal. It is a protection function, auto-subtract the charging current to avoid burn damage to chip.
NO Reversal polarity.
