If you are talking about the plug part that goes into the wall & not the USB cable that goes to the phone then it may work. You need to look at the specs on the wall plug part. It it says the output voltage is 5V, 500mA output to the USB cable or higher mA not Volts then it will work. That's assuming you are using the USB charging cable meant for the battery charging that is right for your battery. Some of the phone changing plugs are only 100mA, they won't work. You need 5V, 500mA for wall or car charging adaptors to power USB cables for PV's.
