ahh, sorry I missed your reply post. I apparently have the memory of a goldfish.
I would have suggested "simply" swapping the output wires from your old charger to the new. I've done that a couple of times. Its easier than getting a replacement plug and putting it on...and those tend to look makeshift anyway.
An adapter makes good sense too!
Is it a bad sign when the manufacturer sends you spare fuses with your charger?
