220V AC to 3.7V DC Lithium-ion 18650 battery Charger Circuit.
Hello friends, today in this video i have shown how to make a 220v to 3.7 v Transformerless Battery Charging Circuit. Please note the circuit is not isolated from maims so don't touch any naked wire in this circuit when the circuit is plugged in.
Parts list:-
105j / 450v pf capacitor
1M resistor
1N 4007 diode
470uf / (16-25v) capacitor
5mm green LED
330Ohm resistor
