Why am I the only person who see's the easy answer here? Go to work EARLY and just swap her power supply with someone else's who was dumb enough to leave theirs at the office? Seriously though - there is an EASY way to get free laptop chargers, phone chargers, etc any day of the week; I have a Macbook Pro charger in my bag, one at my desk and one at home and I only paid for one of 'em. If you ask nice I'll tell you the secret to free shiznit!
