      This PCB is built around a NanJing Top Power ASIC corp. TP4056 charging chip. Search for the datasheet of this part for full details. Everything works as described in the datasheet. The Rprog resistor is 1.2kohm which sets the maximum charging current to 1amp. Beware of over-heating and burning-out the chip at this current! Rprog (the resistor in the centre of the bottom edge of the PCB marked "122") can be changed to a higher value to reduce the charging current and so reduce the power dissipation. e.g., Rprog=4.7Kohm will set the charging current to 250mA. High power dissipation can occur when charging a cell which is discharged. When the cell voltage is <2.9v the charge circuit is in trickle charge mode (130mA). As soon as the cell voltage reaches 2.9v, the charge circuit will switch into constant current charge mode. At 5v input and 1amp charging current, the asic and 0.4ohm series resistor will now dissipate 2 watts between them. This will burn-out the asic very quickly. Provided the circuit is used within its power dissipation limits, it does everything you would expect of a LiIon cell charger.

      Can overheat if used to charge over-discharged cells at the maximum charge current.

      very small size, can charge at 1000mah, very bright led.

      I would prefer a micro usb interface.
