Wanted to Borrow!

I have a friend visiting at the moment who left the charger for her 600D at home and the battery is running low! Is there any kind soul, preferably located on the North Shore, that would have a charger they could spare for the week? She flies home on Sunday so I could return it then. I don't know how long the battery lasts so I might only need to borrow it for a day if a single charge would last her.

Thanks in advance!
