I'm just wondering that when charging different devices via USB is it a standard voltage that is used on all devices? I've got a fuji camera that came with a USB plug and a USB lead which connects to the plug for charging or to the computer. The thing is I lost the plug but I notice that if I used an i-pod plug and connect the camera lead to this it seems to work for charging.
If I where to buy a replacement plug with USB connection to use for the camera do I have to buy the correct one or are they all the same? Also is using the i-pod plug likely to cause any damage to the camera?
