I believe a "currency converter" is a small computer that tells you how much your money is worth. Perhaps you meant a voltage adapter, which I guess probably exists, but may be more expensive than a replacement power supply.
Doh, yeah, that's what I get for typing fast. I ment current, not currency. I can't even edit that now cause you quoted me on that.
I've seen them for sale, but no clue as to how much that one costs.
Cheers guys! I will get a UK power supply from Telegames
