I lost the battery charger for my camera on holiday, so I picked up a new one while I was there, but as it has a US plug that means I would have to buy an adapter to use it over here. I know they're only cheap, but I have a few spare plugs lying around and for convenience sake I was wondering if I could just cut the US plug off and rewire it to a UK one? I'm guessing that's not a problem since the charger says it accepts a 100-240V 50-60Hz input, but the cable only has 2 wires, which I'm guessing are live and neutral. How do I know which one is which? Or does it not matter? Does it matter that it doesn't have an earth wire? And how do I know what amp fuse to use?
