TP4056 Type-C / Micro-USB 5V 1A 18650 Lithium Battery Charger Module | Li-ion Charging Module with Dual Protection Function | Original Module in Pakistan

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 connect point is good. If the input voltage is too high, like 5.2v, the current will be less than 1000mA, it is normal. It is protection function, auto-substract the charging current to avoid burn damage to chip.NO Reveral polarityTP4056 Micro USB1. Feature1). High quality charging Chip TP4056, simple circuit, good protective value, high charging precision. 2). Complete mechanical automation processing, High reliability.3). Automaticlly adjust the output current from 100 to 1000ma by simply changing the fixed resistor on the circuit board.2. Applicationlt can be used to charge for one pcs of lithium battery or serval parallel lithium batteries.3.

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 burnning damage. Besides, it is normal that the chip feel hot when the working temperature of the chip is around 60°.TC4056A Micro USB100% brand new and high quality Charge module- Linear charging.Current- 1A adjustable.Charge precision- 1.5%.Input voltage-4.5V-5.5V.Full charge voltage- 4.2V.Led indicator-red is charging Green is full charged.Input interface- micro USB.Work temperature- -10° to +85°.
