Good day to all. Do you have experience in making usb charger for Li-Ion? You need either a circuit or a specialized microcircuit (are there any) that provides for the installation of a charging process indicator diode.

Up to currents of 1 ampere, you need tp4056
From the pros - there is a charge indication and from the strapping, at least one resistor is set by which the charge current is set.
Ready-made, you can already buy on eBay for space two bucks.
