    I have received the charger today. I haven't tried to connect it yet. The device came with a push button to be installed (soldered) and two resistors, I don't know what for are those two resistors, there is no any place on the board to place a resistor, the only available place is for the switch. It came with a Chinese manual, that I don't understand, but however, I'm sure there is no mention of the two resistors included. I'm not sure about the function of the switch but it might be a discharging

    a clean build on a good quality PCB. it does exactly what the description says and delivers at least 800mA at the output - I didn't test it for higher currents yet. very happy with this one.
