20 LED’s on Mobile Charger

About: Now I am a retired person, who enjoys life and making small things to pass the time keep myself busy.


Many of my friends at Instructables asked me to glow some LED’s by a mobile Charger. Most of the time your Mobile Charger is not in use. So I thought of using it to glow a LED Night lamp as it has a DC power supply.
