I am trying to make a little cell phone charger using a USB socket. I have built it as per the attached diagram.
I get a regulated 5 Volt output but the phone does not seem to be charging the battery monitor shows that its plugged in and charging but the percentage charge seems to go down.
I tried it on my ipod and nothing happened.
Have a left something critical out? Does it need a blocking diode.
Any advice is greatly appreciated.
