• Specifications :
• The TP4056 1A Li-ion Lithium Battery Charging Module – Micro USB is a 3.7V lithium battery charger module that has an onboard Micro USB interface. TP4056 With Micro-USB onboard connector, you can directly connect to the 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. It is small size and lightweight.
• It uses the internal PMOSFET architecture which eliminates the use of a blocking diode. It prevents negative Charge Current Circuit. Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature. The charge voltage is fixed at 4.2V, and the charging current is programmable externally with a single resistor. The TP4056 automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached.
• TP4056 Other features include the current monitor, under-voltage lockout, automatic recharge, and two status pin to indicate charge termination and the presence of an input voltage.
• 1 x TP4056 1A Li-Ion Lithium Battery Charging Module – Micro USB
• I used it to charge dead batteries which i had taken out of old mobile phones. Batteries are working fine now and using the charger is easy. Nice module at low price.
