More Information

  • Designed for use with the 15- or 17-inch MacBook Pro

  • In addition, the magnetic DC helps guide the plug into the system for a quick and secure connection
  • When the connection is secure, an LED located at the head of the DC connector will light; an amber light lets you know that your portable is charging, while a green light tells you that you have a full charge
  • An AC cord is provided with the adapter for maximum cord length
  • The AC wall adapter gives you an even easier and more compact way to travel
  • Designed to be the perfect traveling companion, the adapter has a clever design which allows the DC cable to be wound neatly around itself for easy cable storage

What is there to say about a power adapter

It works just fine. You will need this in order to power your Macbook Pro. I like the older style design better of where the adapter attaches to the laptop. Ergonomically the new one is a little awkward and the cord tends to get ion the way.

Great product, but poorly designed cord housing

I got one with my macbook pro 15" model, and it worked perfectly for a year and a half but then suddenly stopped, and upon further investigation i found that the white rubbery housing around the inner cable had been twisted off which means i have to buy a new one now :(
