Hello, I'm new here and i'm not very expirienced in electronics.
I bought a beard trimmer in ireland, it came with this funny plug:
4.3V output max 70mA
I thought instead of using a plug converter im my home country i maybe could build a little power converter on my own, since i have som resistors laying around at home and use USB to charge it up.
I came up with this little scheme:
I actually don't know the battery's resistance, it's just guessed using ohms law (5V÷70mA=61Ohm).
Do you think this would work to charge up the trimmer without breaking it?
