Mine gives exactly the same numbers as the back of the UK one which suggests that a UK power supply should work fine :-s I'll wait til I can try another charger before I buy anything else as it looks like the problem is a faulty charger or a faulty DS rather than it being incompatible.
Edit: This is REALLY annoying me now. You'd think somewhere on the entire internet someone would have written a clear explanation of all this but I can't find one anywhere
