Question: how long is it?
Document: It was delivered very quickly and is charging an older mac (2009) and a newer mac (2012). I've not had it very long, but it has worked as stated.
received it last week and it works just fine. I only gave it 4 stars because I haven't had it very long but I really don't see any problem on the horizon. Great Price!
why didn't i try this before?
the charger works good for the price i was going to buy a apple official one but they are so expensive .
only worked for few minutes and now its piece of junk.
Works perfectly and is SO MUCH less expensive than the Apple brand. It even has the light to let you know when the computer is charged. I have no complaints.
Works great!

Answer: A little over 8.5 feet long from wall plug to magnetic piece.
