• Programmable charging current (default 1A)
• Charge cycle termination based on charge current drop
• Charging indicator LEDs (RED for charging, BLUE for full)
• Overcurrent protection (external circuitry required)
• Current monitor, under-voltage lockout, and automatic recharge features

  Specifications:  

• Charging Accuracy: 1.5%
• Charging Method: Linear
• Full Charge Voltage: 4.2V
• Input Voltage: 4.5-5.5V
• Rated Power: 4.2W
• Operating Temperature: -10°C to 85°C
• Length: 25mm
• Width: 19mm
• Height: 6mm
• Weight: 3g

  Package Includes:  

• 1 x TP4056 1A Li-Ion Lithium Battery Charging Module – Mini B USB

  Note:  

• This module does not have overcurrent protection, so care should be taken to prevent excessive current flow.
• Connect an ammeter in series with the 5V input for monitoring.
• The charging current should ideally be around 0.37 times the battery capacity.
• Use appropriately sized and short charging wires.
• Ensure good contact between the module and the battery.
• Normal operating temperature of the chip is up to about 60 degrees Celsius.
• Reverse connection of the input has no effect on the chip, but reverse connection of the output (battery) will damage the chip.
