Apple has come out with the new Magsafe called "Magsafe 2" In reality, it has actually gone through 4 revisions. But we guess the reason why it's considered the "Magsafe 2" is because the actual magsafe tip is narrower from top to bottom and a bit wider to accommodate the slim Macbook Airs and the New Macbook Pro retina laptops. The “L” shaped Magsafe is a direct replacement for the original Magsafe and will fit ALL MacBooks, EXCEPT the Magsafe 2 can ONLY be used for the new Macbook Pro Retina and mid 2012 Macbook Air.
Other then the new size of the "Magsafe 2" there is also another minor change in the voltage output of both the 85w model and the 45w models.
The new 85w model is actually 20v at 4.25A. The old was 16.5 - 18.5 at 4.1A. The New model is set at 20v constant, while the old 85W is actually 60w, but powers up to 85w if the Macbook needs it.
The Macbook Air is 14.85v at 3.05A. The old was 14.5 at 3.1A. Not a whole lot different there.
For those who are planning on upgrading to the new "Magsafe 2", you can probably continue using the our old car adapters, but you might come up short of you are a high CPU user. All you'd need to do is purchase the just the "Magsafe 2" cable and plug in the car adapter that you already have from us. Since you just got a brand new Macbook, why no purchase a new car adapter since we will be shipping our adapters with the higher voltages with the "Magsafe 2" cables?
For our existing users, please contact us before you do however, most of you have adjustable voltage adapters and it could simply mean a different voltage selection.
Until next time, Happy charging and powering your Macbook Air and Macbook Retina display on the road (Retina display is gorgeous isn't it?)!

Thanks for the picture clarifying them. It made it so simple to explain the difference.
