5V 1A Type Micro USB 18650 Lithium Battery Charging Board Charger Module + Protection Dual Functions TP4056
- 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 Micro USB connector from USB or external +5V source.
- With a Micro USB onboard connector, you can directly connect to a 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
Specifications
- Chipset: TP4056

- 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: Micro USB
- Size: 25 x 19 x 10mm.
Safety Notes:
- The ampere meter can only be connected to the 5v input end of the module.
- The charging current should be 37% of the battery capacity. If you charge to the battery of 1000mAH, a current of 400mA is enough.
- The connection wire should not be too thick.
- Make sure the connection points are well-soldered.
- If the input voltage is too high, like 5.2v, the current will be less than 1000mA, which is normal. It is a protection function, that auto-subtracts the charging current to avoid burn damage to the chip.
- NO Reversal polarity.
