Features
MagSafe has connector pins that are designed so the rectangular connector can be inserted in either orientation (however, the L-shaped version of the connector can only be fitted in one orientation without blocking neighboring ports, such as USB). LEDs on both sides show green if the computer battery is fully charged and amber or red if the battery is charging. MagSafe can be found on the MacBook, MacBook Pro and MacBook Air notebook computers, as well as the Apple LED Cinema Display.
The MacBook and the 13-inch MacBook Pro use a 60 W MagSafe charger, whereas the 15- and 17-inch MacBook Pro use an 85 W MagSafe charger. The MacBook Air has a lower-powered 45 W version of the MagSafe adapter. The power brick is smaller, but the MagSafe connector is the same as on the 60 W and 85 W chargers. Apple has made it clear that an adapter with the same or higher wattage than originally provided may be used without problems.
Apple also offers a "MagSafe Airline Adapter" for use on certain compatible airplanes. It has a DC input (instead of AC like the original MagSafe chargers) and will power the computer, but will not charge the battery.
On June 11, 2012, a thinner "MagSafe 2" connector was announced at Apple's 2012 Worldwide Developers Conference. It was manufactured in order to fit the (slimmer-than-previous) new MacBook Pro 15-inch with Retina display, as well as the updated line of MacBook Air. It also has a new connector shape based on the original one.

Famous quotes containing the word features:
““It looks as if
Some pallid thing had squashed its features flat
And its eyes shut with overeagerness
To see what people found so interesting
In one another, and had gone to sleep
Of its own stupid lack of understanding,
Or broken its white neck of mushroom stuff
Short off, and died against the windowpane.””
—Robert Frost (1874–1963)
“Art is the child of Nature; yes,
Her darling child, in whom we trace
The features of the mother’s face,
Her aspect and her attitude.”
—Henry Wadsworth Longfellow (1807–1882)
“These, then, will be some of the features of democracy ... it will be, in all likelihood, an agreeable, lawless, particolored commonwealth, dealing with all alike on a footing of equality, whether they be really equal or not.”
—Plato (c. 427–347 B.C.)
